I actually have an asus rt-n58u router (which is SUPER fast and strong), yet I could only get like 5 mbs on my prime! Great signal, but no speed for some reason.
I had the 2.4ghz N-only on channel 11 originally. When I moved it down to 1 or 3 in the 20/40mhz range, it upped the connection speed 5x from where it was so my transformer is connecting at 54-72 mbs instead of the 19 before.
Odd, but give it a try on your router and see what works!
That kind of makes sense - lower frequencies are better able to penetrate solid substances, so it might make the signal strength better.
It's very odd, however, that a drop of only 40 MHz would have such a huge influence if that was the reason. Are you in a highly-populated area? I think it's more likely that there was interference on the other channel. Do you have any other wireless devices to test with? Did you try putting it back to the original channel and seeing if the speeds went back down? Also, were you holding the tablet in the same position during both tests?
I live in a small condo complex, but I used wifi analyzer to see what channels the other networks were in... At my old 11 channel, there were zero, while at 3 there are 2 others to contend with. My laptop works at 300 mpbs at either channel but the prime seems to perform much much better at the lower frequencies.
Odd part is that the signal strength was the same between channels 3 and 11, the only thing that changes was the speed thoroughput. Suddenly the speed listed in Android went from 5mpbs to 65 ish by just changing the channel, yet the db- signal strength remained very good.
If anyone can explain this, I would be all ears.
I recently used Wifi Analyzer to change to channel 11 from 1. Why? Farther away from my router 11 was stronger than 1. So maybe speed is sacrificed by distance & vice versa? Wifi Analyzer also tells which channel is "better" but is it using "better" as determined by???
Interesting, I am playing around with the channels as well, and there seem to be differences in speed of each channel.
I live alone in the woods, where definitely no intereferences from other WiFi Networks appears.
Channel 11 works slightliy faster than channel 1, but I have not tested many configs yet.
The signal strength is not the issue because I am sitting right next to the router, but the speed behaves odd.
I cannot connect to my DLINK DIR 655 on channels 6 and 13, no problems on others.
The Prime WiFi wierdness continues

It determines better based on the channel of other networks in range. So the higher the channel rating, the fewer other networks there are in that frequency range.

looking at this from a physics standpoint, this makes sense. lower frequencies use more energy and so at a higher energy, you're able to pump out more speed. I'm guessing it's the prime that's using more energy since the router is not the device in question...
interesting though...you would think that it wouldn't make such a big difference!
FWIW, I've always gotten much better performance on my wireless network in both terms of speed and connectivity, using channel 1.
what app are you guy suing to test speeds? Speedtest.net

Yup. That seems to be the standard app for speed testing. If you really want to be accurate, the best thing you can do is transfer a large file locally over your WiFi network.

Interference. Other Overlapping wireless routers.
I'm a little skeptical of the OPs findings, as the difference in channels (in the tens of Mhz range) shouldn't make a significant (and definitely not a factor of five) difference in bandwidth. It is interesting though. Can you do some controlled test runs and provide the specific data?
I am just as confused as everyone else...but trust me it makes a big difference.
The DB rating at channel 11 was -40 (lower better), while the DB rating at channel 1 was -38. Again, channel 1 is crowded with other routers, yet 11 or even 14 is empty (no one knows how to properly use their router here!)
I would have full bars (according to android) at the higher wifi channels, yet the prime would only show 5 mbs, sometimes 19, but most of the time around 13-19mbs (per android menu, speedtest around 7 mbs). When I moved to channel 1, the prime (and my droid charge) would go to 52-65mbs (android, 13-15 using speedtest)...but my computer would go to 144mbs only because of no channel bonding.
Moving to 3, a 40mhz channel, my charge would get 52 mbs and my computer bonded to a full 300mbs. Channel 11 is a 40mhz channel too so not sure why 3 is any different than 11 that is also 40mhz, but the speed rates in android is consistently higher.
The test is through one wall, about 20 feet from the router. Could be just my router, but who knows! I have an Asus rt-n56u router, with dual bands. I would be curious to see what the tests would be at the 5ghz band if that was ever enabled in android.
My tests were in a controlled place, same spot for laptop, droid charge and my prime. All i did was change the wifi channels from 11 to 7 to 3 to 1 and see how it changed the speeds.
I measured the rates speed provided in android from the wifi interface and also used speedtest on all 3 to rate actual speeds. speedtest results went from 6-7mbs at channels 11, to around 15-16 at 1. Just checked again this morning and still faster.
Here is a wiki article picture on the bands:
http://en.wikipedia.org/wiki/File:NonOverlappingChannels2.4GHzWLAN-en.svg
I also got a significant speed boost from moving off channel 11 onto 1. Went from 3mbit to 14mbit
I am about to conduct my own channel 1 versus channel 11 tests right now...
I've just tried it on mine and Channel 1 and 11 were near identical and 3 halved my DL speed.
Did the most scientific test I could. Never moved tablet, same environment, same location, 10 feet from router, Los Angeles server, ran 5 tests as quick as possible on each channel - with 3 minutes in between to change channels and let the change settle - and then spent 3 minutes watching dbm strengths on each after all tests complete
CHANNEL 11 =2462mhz
0. ping ms/ down mbps / up mbps
1. 24 / 20.15 / 1.15
2. 22 / 20.44 / 1.16
3. 21 / 19.92 / 1.16
4. 18 / 21.81 / 1.17
5. 24 / 21.26 / 1.17
*high and low dbm over 3 minutes -36 to -47
CHANNEL 1 = 2412mhz
0. ping ms/ down mbps / up mbps
1. 21 / 19.84 / 1.16
2. 22 / 20.57 / 1.15
3. 23 / 21 / 1.13
4. 21 / 20.79 / 1.16
5. 23 / 20.34 / 1.15
*high and low dbm over 3 minutes -39 to -43
Results = Negligible differences with 1 real benefit to channel 11 shown by Wifi Analyzer is that it reachs around my home farther. Channel 11 seemed to stick to better dbm ratings but had wider range in high to low but stayed mostly in 30's. Channel 11 got the best average up speeds barely. Channel 11 got the best average down speeds barely. Channel 1 barley had best average png. As well, of the other neighbors signals I pick up, most are in 1 and 6 - no one on 11 but me. Thus, I will stay on channel 11 for all obvious reasons.

Looks like maybe you conducted your tests close enough to the router that the bottleneck is in your internet connection, rather than the wireless connection. Try again far enough away that the connection drops to like half of that speed on channel 11. If the speeds are still the same then, that will be strong evidence that it's local conditions causing the speed boost for those who report it.
This may be related to your routers and not the TF.

Easy enough.. will do maybe tomorrow at same time of day to try to best mimic and remove confounding variables best as possible (though saturday may have more congestion as people are home). Either way, will do in my living room, farthest point from my router. Will be interesting to see how distance changes results.
I just got around to downloading the speed test app to see how fast me x2 is and after the first test here is what I got:
Ping:19ms
Down:4989kbps
Up:703kbps
Now I dont know much but something tells me that up speed is a little low.
Im on cm7 with the Mash up script and wifi on.
Will the numbers be different if Im on 3G? Are these numbers even remotely good?
Many thanks to all!!
Apps aren't always accurate. I'm not sure what you meant will it be different if I'm on 3G? Wifi and 3G will always differ, wifi is much faster depending on your provider, where 3g can lag at times
On 3g I usually hit 3d and 1 up
Where wifi I'm like 25 down 8 up out there about.
SMILE It's Not Illegal Yet
Your ping time and up/down speeds can vary even when connected to the same tower or wifi network depending the congestion at any given time on the bandwidth provider's network, among other factors.
Your seemingly low upload speed could be attributed to other devices on the wifi network using the upload bandwidth allotted by the isp at the time you performed the speed test. It may also be the case the connection supplying the wifi network is 6Mbps down/1Mbps up. Your upload and download speeds while on wifi can only be as good as the connection from the isp regardless of the settings on your device or how many other devices are on the network.
For what it's worth, I have a Verizon 3G Network Extender plugged into my wireless router, meaning that both my WiFi and the Network Extender can only supply a connection that at best is only as fast as my cable modem's connection to Comcast. Eliminating all conflicting variables (e.g. no other devices on the network when running tests), my Droid X2's 3G upload and download speeds are consistently slower than when I'm on wifi.
19ms is a pretty good ping time, btw.
Lots of useful info. Thanks guys!

I have also been curious and suspicious of my 3g data speeds. When I was stock and rooted with 2.3.4 I would get on average 20-30 kilobytes/sec in my house with a poorer signnal of -87dbm this is using speed test and checking the down up speeds with the mobile network app that puts the speeds up on the notification bar. I used that to monitor downloads and web browsing speeds which agreed well with speed test. In a good coverage area -67dbm I achieved pretty consistently 130-230 kilobytes/sec. I am now running eclipse 2.0.4 with CMDA build.prop edit to increase 3g speeds. I ve only noticed a doubling of speed when in -87dbma area nut otherwise I cannot achieve anyhigher than 300 kilobytes/sec. I wonder could my radio be weak or bad? I thought 3g speeds would but up to ~500 or greater in really good coverage areas.

I never considered radio quality when I looked at my speeds. Exactly how one would go about checking ones radio quality is far beyond me. Its definitely something worth exploring (in my opinion)
Right I would also need to test other 3g speeds on a different phone on the same networko in the same area to rule out network end probs. Plus I got my DROID x2 used so that might be it there. Also if the radio heats up from persistent use that might reduce efficiency and lower speeds.
Those are fairly decent speeds. For a mobile device, that's about what I would expect. Your ping, 19ms, means that it takes .019 second to reach from your device to the Verizon servers, then to the servers of the sites you are accessing, and then finally back to your phone. Anything less than 80ms is considered good, so you have an excellent ping.
And to clarify, your upload speed will never be as high as your download speed. It's a throttling mechanism used by all (and I do mean all) internet providers of any kind to prevent things like hogging their bandwidth with torrents and the like. It's essentially an industry standard.
In this day and age of 802.11n I would have thought that a tablet would consistently connect at speeds of 100 - 150 Mbps, even 300 Mbps doesn't seem like an unreasonable expectation if the signal strength is good. However, the fastest I've seen on my Tab Z is 72 Mbps. Is this speed a hardware limitation? Anyone connecting faster?
Answer:
What makes 802.11n different is the specification’s support of multiple radios and antennas that can transmit/receive multiple data streams – called spatial streams. In 802.11n vernacular, these send and receive antenna configurations are noted as 1×1, 1×2, 2×2, or 3×3. These numbers indicate how many transmit and receive antennas and radios are in an 802.11n access point (AP) or client. They determine how many different spatial streams of data can be sent at one time to improve signal reception.
More antennas and streams mean faster speeds, less dead zones, fewer dropped connections, and better coverage. 802.11n 1×1 Wi-Fi adapters don’t take advantage of 802.11n’s multi-stream capabilities so they can only reach a maximum data rate of 72 Mbps. A 1×2 802.11n adapter with two receive streams can double the maximum data rate to 150 Mbps. Take it up to 3×3, the maximum data link can reach 450 Mbps.

Why not try Googling "wireless n 72mbps" - you'll see loads of stuff about this on various devices

Good and how do we go from 72 mbps to 100 mbps or more.
There are solutions for this?
Try using 5Ghz router.

probably your device connects to 2.4Ghz band on your router. Check your settings to connect it in 5Ghz mode.

i check this and i have the same problem i buy a new rooter and i have the same problem
No matter what i do I can only get 65Mbits (10Meg) per second (and thats on 5Ghz) Is this the max speed the phone can handle? I have 150Mbit per second internet connection.
Im good here...

How did you attach your screenshot, I'm trying to add mine and can't find an option to add an attachment.
NEed to be a bit more specific....
Airplane mode on, then wifi on, speed test, should usually get you 80mbps or higher..
The real test is doing a SMB or internal network transfer... can only get 5-8MB if I am lucky...
First phone was 500k for internal SMB. Speed test always shows great speed going out, but never on a local network..
My speed is super ok WiFi up 380 / down 411 Mbps
I get the advertisex ISP speed (120mpbs) using the speedtest app.
SMB I just about get 1 MB/s
Are you getting 8 MBytes/s ie 64 mbps? I would be very happy that. I warch videos by running the straight of a network drive, the get choppy.
Hi.
What wifi speeds is the galaxy S9 plus capable of. I have Gigabit broadband and the max speed I can get on the 5Ghz is 160mbps.
The router from provider isn't the best
Will I get much higher speeds if I upgraded my router or purchased a wireless access point connected to 1gb LAN port and access point capable of 1300mbps on 5Ghz?
Thanks
I have 500Mbps from my provider plus custom router(DIR-882) AC2600 MU-MIMO. And this is what I can get(400Mbps) from room next to my router(3m + wall/door) : http://www.speedtest.net/my-result/a/4290259062
I've gotten up to about 530mbps once in a while. More typically just under 500.
You need a high end router in order to get higher speeds over WiFi
Try to change to a not frequented channel and set the Bandwith to 80MHz.
I can get 800Mbit/s when nobody other is using the WiFi.
Allways 866Mbps guys.
Tp-Link Vr900
But when i send videos to the nas usually the speed is 40mb/s
Maybe your drive in the NAS can only write with 40MB/s. Remember, that 40MB/s are 320Mbit/s.

I think that with 1+6 i was writing with 50-60mb/s.
Also my nas can write with 1gbit connection (lan) 100mb/s.
Do you have any sort of an extra firewall on your phone?
View attachment 4609511
My S9+ will connect via 5GHz to my Netgear R8500 at a LAN speed of 1083Mbps - but you have to be within 3m/10ft to get that speed. It falls back to 866Mbps pretty quickly if you are only just a little further away.
Real-world download/throughput performance will be lower.
