Perhaps I was being complacent, but I just assumed the prime would hop on the 5ghz network in my house....but in fact I can only see the 2ghz network. Anyone have input on this?

The TP has a Broadcom BCM4329 chip which does support 5GHz mode of operation. However, Asus did not include the support for running the device at that mode, either in software or due to the type of antennas used. Could be for saving power..
Perhaps we might see a custom ROM which enables this mode of operation.
This sucks! I just got my prime and I can't use the 5ghz speeds in my house to stream HD video.
I've tried the 2.4ghz N speeds but the max speed is about 65mbps...nothing close to the 130mbps that my laptop gets. And, this is next to the router.
When I tried to stream HD video from my home server, it is a bit choppy and has lots of dropped frames.
Any suggestions???

Though I would agree with you that it's a major bummer, I don't know why it's surprising,. This limitation has been mentioned before, research is your friend...especially when you're giving them $500 of your hard-earned money.

It was on the front page for a while in the same thread discussing the single speaker. It is wierd that the chip supports it but they disabled it.

Don't know why it was disable and I don't think the hardware is there it can't be for power savings the iPad 2 has it
I don't think its fair to say the consumers in general are going to be able to spot the fact that this doesn't have 5ghz. You'd have to be somewhat technical and do a lot of digging. As long as the wireless N standard has been around, it is very odd to me that they disabled this.
5ghz is great for streaming video and I'm having a lot of trouble with 2.4ghz streaming clean HD video.

I would say consumers in general are using 2.4ghz and the somewhat technical are using 5ghz. Personally I tried using 5ghz in my house but the range limitation put me back on 2.4ghz since I didn't want access points set up all over the place.
I dunno i think they should have still made it available. If it sucks the power up then people can switch. I am forced to use 2.4ghz at home because my phone doesnt support it but being that i will be using the tablet instead it be nice to switch back to 5ghz.
The hardware supports it so thats good atleast, which means asus or a dev can enable it in the future.

While the 2.GHz band is narrower and frequently more crowded, it isn't inherently slower -- at least not so much that it would cause the video streaming problems cited here. Using WiFi Analyser I am able to see the channels in use in my area by WiFi and changed the channels used by my router. My initial change failed - maybe I chose a channel with a lot of non-WiFi traffic on it. But my 2nd choice worked brilliantly. I can stream HD from my Twonky over WiFi with no problems.

What do you guys think for the tradeoff? $100 for an uglier plastic backing (just for wifi and gps, although I'm having no issues with my wifi and gps atm) with a 1080P on a tablet with only a 10'' screen?

updated video link, unlisted video.
I like how the back looks. I don't know why, the black strip looks good to me
I think it looks really bad compared to the Prime^^ Also it seems waaay thicker on those pictures. Could be due to the high resolution display? Or it could just seem that way because of the picture.
Must be the picture as they claim T201 and TF700T use the same dock mount. The dock mount has front and rear guide/stabilization rims which the TF700T has to fit between, so it must be same height/thickness.
Does anyone know must you use a sim card inside the 3G Prime to get better working WiFi or will it have better WiFi performance just by using WiFi only over the original Prime?
WiFi only is really all I need just trying to work out if its possible to use the 3G version as WiFi only.

Um... what 3G Transformer Prime? There is none at the moment.
If there was a 3G Transformer Prime, you can be sure there will be a plastic RF window for better RF transparency, like the strip the TF700T has, or the Wifi Ipad versus the 3G one.

I can only connect to the 2.5 Ghz frequency.
I know the 5Ghz works because my laptop can access it. I want to take advantage of the troughput the wireless "N" gives you.
It's listed in the specs that the TF201 only supports 2.4 ghz wifi. *shrug* What else is there to say?

The 5ghz N range is way overated. Not as good as people think as your range is more limited than 2.5Ghz.

No where in the article they mention about crowded frequencies. You know how your troughput degrades when your home is bombarded with all the WiFi access points advertising in the same frequency (dif. channel). Is this also true?
Different channels use different frequencies inside the 2.4Ghz spectrum. Use Wifi Analyzer to find an unused channel in your vicinity.

Will do.
Once I find a clear or not so crowded channel, how do I go about having the Prime use that channel?
The router end is easy to change.
Will that involve ADB come into the picture?

Once you change the channel on the router, all client devices, including your tablet, will find the network on the new channel and connect to it.
that was a dumm question from my part.
I will downlaod WiFi analyzer from the market and run it once I get home.
Thank you.
Yeah,wifi analyzer is a great free app. It will let you see what channels are crowded n what's the best one to switch your router to. Plus will let you see a real time signal strength meter also for whatever channel you on. Glad the article helped.
+1 recommendation of using wifi analyzer app.. very good and useful app
Do keep in mind that the app only shows wifi AP's and what channel they are on. It doesn't show how busy they are. Only way to see that is to use an PC with linux running something like Kismet. Kismet will let you see how many packets are being sent on a given channel so you can dodge busy wifi channels that are being used for bittorrent, netflix, etc.,.
Second, notice the parabolic arcs in wifi analyzer and remember that 2.4Ghz frequency channels have some overlap. Many people don't understand that moving their AP a signal channel up/down does nearly nothing to avoid the busy channel's traffic. Due to overlap, an AP on channel 2 will still see interference/traffic from an AP on channel 1.
Which is why I wish the TF201 was 5Ghz capable. 2.4 Ghz airspace is very crowded where I live. But 5Ghz is nearly empty except for my AP and one other. I can copy over 30mb per second via 5Ghz on my laptop but, as the other poster mentioned, range is better on 2.4Ghz.
Developers are looking into enabling the 5ghz frequency as the info or instruction set for it is inside the prime already. So it seems as if Asus just disabled it or something similar. There is a thread somewhere around here on it..lol
Right.
In my case all I needed to find out was how many APs were using the same channel as I. WiFi analyzer did its job. There were 4 APs using the same channel as I was. Changed the broadcast channel in my router and it's smooth sailing for me now.
I'm streaming Blue ray quality movies to the prime from a share drive with no lag unlike before.

I was just making a sarcastic comment.
Hello people,
This is not the normal complaint thread about WiFi and Bluetooth issues, so please don't flame without reading.
I have managed to reproduce and NOT reproduce the WiFi speed issues when streaming data or audio thru Bluetooth, and I have found a pattern.
I'm almost sure it is a Software issue. With the Prime running WiFi and Bluetooth over the same chip/antenna it is normal to have a speed drop when using both, but not to bring WiFi speed to a crawl (300kbps tops).
So, what I'm asking for is information about the Bluetooth device you are using, if you can give me brand and specific model better, the more information I have about the device the merrier
Second, I need information about your Wifi speed with stream and without stream or at leleast if you have major speed drops or your if Prime works well.
Ill be going this weekend to Saturn or something to try top-notch super expensive Bluetooth devices and see the results.
What is the pattern you found? It might explain why some people bt/wifi works fine and others dont.

Something about the Bluetooth profile being used by the tablet when connecting to devices.
I posted some videos about my prime being able to stream HD video while listening to it through Bluetooth. And some speed tests while using my AKG 830BT headphones.
What was my surprise when using the cheaper Motorola DC800 Bluetooth receiver or headphones? The issue everyone was complaining about here, WiFi speeds of 150K... which of course is useless for anything but chatting.
Doing some research I've found out that those motorola devices use older BT versions (2.0) and one of them does not have HQ A2DP audio.
Long story made short, after testing a few of the BTdevices I own, I found out some of them cause issues while others not.
That's why I'm asking now here, users with and without issues to post their BT Device Models/Brand so I can search which BTprofiles are being used and if some of them are causing issues.

This makes sense though since it most likely is a hardware issue. A2DP is high bandwidth. The identified cause of our woes is the fact that wifi and bluetooth are on a single module. So when A2DP is being used, most of the modules time is used on bluetooth and less on wifi, thus slowing down speeds. The solution from ASUS was using RMAs to add another module so that one is dedicated to wifi and the other to bluetooth.
I could be wrong though.

It would make sense, if it wasn't backwards!
The High Quality A2DP Profile audio is the one NOT killing my WiFi speeds. Every time my Prime connects to an older device using one of the other profiles the WiFi speeds go to hell.
Both WiFi/Bluetooth being in the same Module can cause speed drops, but not completely kill WiFi Speeds.
These are my speeds when using the AKGs Headphones:
No BT stream: 24.91 Mbps.
BT Audio streaming: 18.13 Mbps.
(video and stuff here)
That speed difference IS the one caused by both running on the same chip.
Same tablet, same router, but I change the headphones and the speed wont go past 150kbps. Doesnt matter if the prime is sitting on the router.
Anyways, I'm asking the people who was complaining about the speed (and those whose Primes do work)to feed some info, it is not like I'm gonna waste others time Ill do the research and tests. Just need a bigger data pool.
Go for it. Good luck

How bad is your WiFi loss, partial loss (normal from using WiFi/BT on same chip) or total, like going down to 150K~?
I have never measured as I just don't use the combo anymore. I know it happens, got frustrated, and use my wired ear buds after the first few weeks of owning the tablet. It does have the signal degrade though. The headset is about 2yrs old.
I can test it out when I get home. The work wifi is limited to 750kb download speeds per user.
I have a Netgear WNDR3700V1 with fibre 35/35mbit
Using the Plantronics BT300 headset the wifi drop to under 1 mbit or almost zero, YouTube buffers.
Without BT I have full speed above 30mbit at least.
The only way to "avoid buffering and dropouts" is to use a WN3000 Netgear Extender in same room where the Prime is.
This way I manage to listen to Youtube without drops.
So if the signal is still stron the loss is "not bad", but how many do have 35mbit up and down with fibre.
Those with low speed, will still have drops.
Wifi specs for N10 is listed as "WiFi 802.11 b/g/n (MIMO+HT40)". Can anyone confirm that this is indeed dual-band (2.4 & 5GHz), because HT40 mode is well nigh useless in 2.4GHz--the reason being that 40MHz mode would eat up about 2/3 of the entire usable allotted 2.4GHz spectrum, and would be extremely unfriendly to neighboring devices. Most routers don't allow 40MHz mode in 2.4GHz band.
Now that 4.2 supports Miracast, 5GHz support for high throughput is pretty much a necessity. Kindle Fire HD has dual-band, and it's kinda the baseline for tablets. Thus I'm assuming the same for N10, but would like confirmation.
Check this link: https://sites.google.com/site/androidpresssite/home/tech-specs
It says "Dual-band Wi-Fi 802.11 b/g/n (MIMO+HT40)"
I would think this is 2.4 & 5GHz. Samsung has been using dual band in most of their products. So, don't think this would be any different.

>But wouldn't you expect a listing of 802.11a then as well?
That was the erstwhile practice, posting abgn spec as an indicator of dual-band capability, hence my question. But .11a has been out of fashion for years now, so phasing it out of the specs list is a good thing. I did check into a few recent wifi adapters with dual-band support, and the 'a' is not present in their specs.
I doubt normal users would notice whether a tablet is dual-band--at least for now. But Miracast capability should push dual-band awareness to the fore, and I expect the next gen of tablets will have dual-band alongside Miracast. The trend is already set for the latest entrants--Surface RT, KFHD, and N4/N10 all have dual-band and MIMO ants. N10 in particular has HT40, which would be useful since it will be outputting 1080p, whereas the others only need to output ~720p.
i think dual-band is a definite necessity in any of today's tablets, I couldn't believe the nexus 7 didn't have one when I originally bought one, then was astonished Asus would drop the ball even on the infinity! A mid-2012 device that retails for $500, without dual-band! Crazy talk I say!

This is outside my range of knowledge, but I ran a few Google searches.
"The Nexus 10 does have enterprise-class wireless networking hardware, with dual-band 802.11n supported alongside MIMO internal antennas (oddly, 5GHz 802 11a has dropped off the specifications — probably because nobody has ever cared very much)."
The Nexus 10 features the latest 5GHz, MIMO Wi-Fi 802.11n. Its wireless performance was considerably faster than the Google Nexus 7, but not as fast as the fourth-generation iPad. On a 5GHz, high-speed corporate network using the Ookla Speedtest.net app, the Nexus 10 averaged an admirable 22.3Mbps down, while the iPad 4 hit 37Mbps down.
Dual-band Wi-Fi 802.11 b/g/n (MIMO+HT40), Bluetooth, Dual-side NFC (Android Beam)
I assume "dual-band" is what you're looking for. One article I read mentioned that it had 5GHz 802.11n. Anyway, the pcmag review -- where they ran the Ookla Speedtest.net app -- sounds like an intelligent, reliable source. I hope that's the info you're looking for.

I believe the specs were a 64-bit dual channel memory interface w
Yes it does have high memory bandwidth for a tablet or phone, but that memory bandwidth is actually just the theoretical max and furthermore is completely used up by the devices screen resolution. It may be high compared to what past devices have had, but it is still not enough for what the device should have. I believe the specs were a 64-bit dual channel memory interface with low power DDR3-800 speed memory chips. Samsung really should have gone with their incredibly cheap and high density 1333 chips since it probably wouldnt have even cost anything more.
This lack of memory bandwidth was my reason for making a thread a couple days ago on the possibility of adding RAM overclocking to kernel tunables, and possibly even RAM timing adjustments. The largest thing holding back gaming and benchmark performance will be the memory bandwidth, second worst thing will be the GPU speed
As for wifi, Ill know for sure when my device gets here in a day or two but I would suspect it will have both 2.4 and 5GHz bands. No sense having MIMO and HT40 if it doesnt even support 5GHz

That's twice the bandwidth of the fastest Tegra 3 devices. I was just looking at the GL offscreen benches, too, and the GPU seems quite capable. The hardware is there; if there are performance problems, they must be firmware or software issues -- and correctable.

Not yet they are not worth it. If you do some research on AC it will double in speed and bandwidth in the next gen of AC devices. Besides it will take some time for devices to gain native AC support. Think back to when N (draft) came out and only the last year or so has really maxed the potential of N capabillities. Id wait. Just my 2 cents.
>Does anyone know if the Nexus 10 will benefit from a 802.11AC router, like for example the Linksys AC1750 or NetGear R6300? Is getting a 802.11 AC router worthwhile?
802.11ac requires hardware on both ends to potentially realize the higher speed. And even when the equipment has the label, it doesn't mean that it has the additional hardware (radios & antennas) needed to attain higher bandwidth. Nexus 10 doesn't have, nor can it be upgraded to .11ac.
Moreover, 802.11ac is not finalized, and all AC equipment are draft-based. That means brand-interoperability is low, and it's best to buy both router & adapter from the same vendor.
These said, a new 802.11ac router may confer benefits if its N portion performs better than your present router.
Suggest reading reviews of current draft-AC routers for better grasp of the pros and cons. Here's a typical review from a respected site:

Thank you very much for that reply. Just to be clear so I understand this properly; the Nexus 10 does not have a 802.11AC chipset? I'm better off getting a 802.11N router that is able to do 450x450?
I don't know about speeds, but my N10 connects to my 5ghz network and performs better there (i.e. no YouTube buffering problem) whilst performing worse on the 2.4ghz (a few disconnects here and there)
If you have a decent proximity to your router you will almost be better served using the 5ghz instead of 2.4ghz because of saturation. In my neighborhood I've had to turn my router power up considerably just get a foothold on my living area with my 2.4ghz devices. I use 5ghz instead with my n10 and the performance is awesome. If it only had less screen issues! Mechanically it is amazing.

My N10 has a 5ghz 40mhz band all to itself at the office, which leads to some rather nice transfer rates when I'm grabbing 720p tv show rips from the NAS.
It's the fastest device on wifi in general I've owned. Very pleased with it.
one more question:
my router does not support 5ghz, but it does support 2.4ghz and 40Mhz mode.
Will the N10 support that, too?

Good question: or better, what is the max connection rate on each band?
Does it have 2 or three antennas and support 40MHz mode on both?
Wil check tonight with my ASUS N66U (2*450) and let you know.
Cheers
Why is it that once I connect to miracast it will disconnect from wifi? Is it hardware limitation or software bug? My Samsung note 2 can connect on both miracast and still maintain wifi connection.

I believe that Sonys implementation of Miracast is wrong.
From what I read, Miracast it self allows for up to 10 connections and as you say your Samsung Galaxy Note 2 can handle both network connection and Miracast.
There's two threads at Sony's Xperia Forum that discuss this problem.
At first the Xperia Team said it was by design, but when several users explained that Samsung phones can have a Wifi connection active at the same time and that all Nexus phones running 4.2.2 could also handle this,
then the Xperia Team said that they would escalate the issue, but after that there has been no more feedback...

This is actually a really bad thing. I also purchased the push2tv system so could stream Netflix and YouTube from my tablet. No luck with that. My HTC one does it without problems.
I am starting to think that what if the random wifi disconnections are related and is because Sony uses only one antenna while there should be two.

actually the tablet z uses MIMO and has 2 antennas. in my opinion it´s clearly a software restriction.
I had the same issue since i bought the dock and push2tv for the same reason. Unfortunately nothing so far. It is definitely a software problem as Sony seems to have fixed it with the Xperia Z Ultra. It works fine while still connected to wifi.
The Xperia Z disconnects also by the way.

Is it a restriction on the S4, over Snapdragon 800? That could be why the Ultra (and then Honami) works.

So it was not fixed with 4.2.2? LOL

No. I have to assume it's a hardware restriction then, or Sony can't or won't fix it.
I am now using MHL, which seems like a far easier solution - although even that cuts the performance of the phone considerably. Epic Citadel can benchmark at around 59fps on the phone display, but output via HDMI and it drops things to 30-40fps.

weird, some say it works on T, so why would XZ and XTZ be affected?

That's weird if it works on the T. I think this needs to be clarified. If it does, Sony really should be able to make it work, or else asked why they went backwards with the Z/TZ by changing the Wi-Fi specs/antennas.
I am going to go and check my Nexus 4 and see if that retains the connection. Previously I couldn't connect it to my TV but a new LG update on the TV has hopefully fixed things.
So did Sony really f*ck this up here. Unbelievable..I must say that I am so disappointed now. I was hoping to stream Netflix from the tablet.
Maybe I then have to get chromecast when available in Europe. I assume that it doesn't use miracast to do the streaming but likely it will stream on its own.

Right, just tried my Nexus 4 and it does keep the Wi-Fi connection. However, there's a lot more lag and the TV image doesn't quite keep up. What's more, the picture breaks up when it doesn't on the Xperia Z.
However, having an Internet connection does of course mean you can now stream TV and movies with Netflix or Google Play. Play crashed when playing a film though, and I have to say I didn't realise it could output a different screen. Netflix doesn't support this, and I'm not sure what else might (perhaps YouTube and other Google apps?).
Anyway, here are some photos I took;

Forget it, guys.
This concept of streaming stuff from the tablet is going to fade anyway.
For Youtube, Netflix etc. simply shell out $35 and get a Chromecast.
Or buy a Raspberry Pi and make your own Chromecast-y device.
Or buy a Satellite receiver like the Vu+ Solo2 and use Airplayer plugin.
All these solutions have in common that the streaming happens on the other device, not the tablet, and therefore is simply more stable and reliable (especially when a wired network connection is used). The tablet is only a controller, a"chooser" for media. (That's also more battery-friendly, by the way.)
Yes I know it should keep the wifi connection. I am mirrorring with my HTC One and wifi doesn't disconnect.
Only problem with HTC One is that after using for an hour or so the phone will get so hot that I get some warning message about it.
So that much for watching a movie like that.

Yes thats basically the better way to do it. I also do have WDTV Live and I can basically use Youtube so that I control with tablet and play on the big screen. Unfortunately the software on WDTV Live is buggy as hell and it crashes every now and then.
Also for some reason Netflix doesn't have this similar possibility.

I agree that the Chromecast way of doing things is the way forward for streaming services. However, I'd have liked to be able to play games without lag/dropped frames on the big-screen - and it seems that with or without the Wi-Fi connection staying open, the quality isn't quite there.
Maybe Snapdragon 800 improves this - and that could be something to sway me towards Honami - but perhaps Miracast will remain useful for showing off photo and videos stored locally (your own content) as a far better option than DLNA that rarely, if ever, works with modern video formats and resolutions.
Things like Miracast etc. are mostly used at home, where you have your TV or projector.
But at home it's not necessary to store the videos on a tablet and then stream them to the TV.
At home one has some kind of NAS from which the files are fetched.
I admit that for a long time I also thought about using the tablet as media hub / storage.
But if one thinks a bit about it and researches, it becomes obvious that much better and tried-and-tested options exist.
And for all other cases (like projecting different apps or playing a game on the big screen) the Tablet Z has a MHL/HDMI output, that's what it's for.

Even MHL slows the phone down, which must be a hardware limitation of the phone.
SlimPort is even worse. I don't know what sort of handshaking is carried out with that, but on my Nexus 4 when I was at CES I was on the stand of a company making them and we hooked my phone up to have the phone crash (even restarting on occasion) within seconds of connecting it.
I'd be interested to see if Snapdragon 800 has less problems with TV output, via Miracast or a cable - but the idea of using the smartphone as a remote to control streaming directly to a device (like a TV with a wired Internet connection) certainly makes sense. Google has once again come up with something great here, and it's probably totally the opposite of the direction Apple intends to take TV in the future.
Miracast
Hi guys, has anyone else had problems connecting their XTZ using miracast? I have the push2tv and my HTC One connects perfectly, but my Xperia tablet gives the error "Could not turn on screen mirroring. The output device does not support HDCP". It seems very strange as the tablet is listed the supported devices on Netgear's site.
I have the 312 version, and have the latest firmware on the push2tv.
this problem definitely not solved within 4.2 update. Dissapointing.

This ist what I posted in the sony forum thread under talk.sonymobile.com/t5/Xperia-Tablet-Z/Can-t-do-Screen-Mirroring-miracast-and-WiFi-connection/td-p/333179/page/3[/url]
Sooo, installed Cyanogenmod 10.2 (based on Android 4.3 which supports WiDi/Miracast natively) and see there:
WIDI/Miracast and the connection to my home WiFi Network work simultaneously.....!!!
So Sony, two lessons for you here:
1. Get of your collective ***** and get Android 4.3 going without nerfing perfectly fine core features
2. If you're going the forum/community way, provide correct information (aka really ask your developers) and don't spew half informed nonsense/play the information hiding game...
To everyone else here: give them ****, or they will never learn!
PS: Who wants to try, google Cyanogenmod ("Pollux" -for LTE variant- or "Pollux_Windy" -for WiFi only variant-). Warning!: Possible Warranty void when flashing custom ROMS
