HI everyone.
Ok, so my luck with mounts runs parallel to my luck with women. Got one, just not the right one... b'doom - tchsss!! (always open with a joke).
I can get the sounds coming through the speaker fine (though I have to not plug it all the way into the XDAiis) and it accepts voice commands etc, the only problem is - the damn "dibide dibide dibide deeeeee" noise that keeps coming through the speaker!
Is there no way to guard against this happening? (in case you can't work out my phronetic typing, I mean the interference caused by the phone's radio waves (or whatever the hell they are).
I saw mention of an external antenna for the phone - surely not - there must be an easier way - wrapping in tin foil maybe?
If there's a secret to getting this to work without interference, PLEASE share it - it's driving me potty!!

the easyest way is to swap to a pcn (orange)network not gsm(o2) pcn transmits on 1800 mhz and does not usally affect electronics as bad.
all vw car radios phone input suffers the same problem on o2 and vodaphone, orange and tmob are fine
Believe me, in January, when my contract ends, I'm going to go back to Orange!! But for the time being, I'm looking for something to stop this until then.
(Not that I'm completely unhappy with O2, it's just there's SO many thigns you have to forgive (Not getting reception in the area where I live being a large one!))
Thanks for your suggestion, more ideas welcomed.

Has anyone come across this before? It cannot possibly work, could it? I don't even understand how it's supposed to function. "the HTC Hero antenna booster also captures stray radiation emitting from within the housing of your wireless phone and uses it in order to improve performance of your phone"
So it catches radio waves in my house, attaches the signals from my phone to them and together they fly far, far away?
Anyone?
those have been around for years.
its not unique to the hero.
they are worthless, and if you can get it for $2, mobile phone manufacturers could develop them for alot less and implement them.
Well said!
There are also versions of these things with LEDs inside -I can only gues, but these things must be decreasing the signal strength, as the LEDs are consuming power from the antenna signal, right?
Hello,
I just bought a GTab and am really excited about it. However, I am not particularly happy with the wi-fi range of the device. It goes to zero bars barely 15 feet away from the router. Did anyone else face similar problems? Let me know
Yup. I lose a bar just by turning my chair away from my router. No solution so far.
Thanks, How long have you had the device? Did you contact Customer Service?
Could be your router. I have no problem using my tab anywhere in the house and out on the patio with a crappy old D-link.
I don't get a full signal, but it is enough to stream my music and browse fine.
Google "cantenna" and you will find a cheap and easy way to extend your range.
This is actually one thing that amazed me about the g-tablet. I Took my g-tab to my mom's house and logged into their unsecured Linksys router. It worked fine, no issues whatsoever. My mother lives a block from the church where I serve as an elder (roughly 50-60 yards away...) I took my g-tablet to a meeting one evening, opened the case, and found that I was already connected to network. I hadn't had a chance to set up the church's network yet...the Tablet actually automatically connected to my mother's network. The signal isn't the strongest, but I hadn't expected ANY signal whatsoever. It works fine in every room of my house as well.
I ended up setting up the Church's network, but the g-tab still automatically connects to my mother's when I'm anywhere near there. My Pastor said that it's because the church's router is has protection and that typically linux based devices tend ot take the path of least resistence. I'd prefer if it checked for the strongest signal, first, though.
I agree it soundls like your router unless you got a leamon. My router is in m livingroom and my gTab drops only one bar when it is in the bedroom, meaning the wifi signal is going through the bathroom to get there, through 2 walls and maybe 15 feet, no line of sight.
When it is charging in the kitchen the signal goes 20 feet and through one wall, again no line of sight, and if I position the tablet just right I can get no bars dropped.
I have a wifi-g router, Westell I think (whatever wifi router Verizon sent me lol). I haven't tried the gTab outside yet, but my daughter's iPod tough can get a weak signal in the back yard and the router is in the livingroom at the front of the house.

Well, Mike, this is where the materials used in buiding construction might make a difference.
If sudeep_itbhu is here in India, then the WiFi signals have to pass through dense brick or stone walls to reach his gTablet. In the US, the signals might just have to pass through things like wood or plaster which won't absorb the signals as much. I've brought access points from the US to India only to have it fail miserably because of our brick walls.
sudeep_itbhu, you could try boosting the "Transmit Power" on your wireless router or AP. You can usually change that setting via a browser if you connect to the router.
Of course, my signal is going (from my mother's 100+ year old house to the 80 year old church lounge) through one interior wall, one exterior wall aluminum siding, 50 - 60 yards though a couple trees, power lines all around, through the brick exterior church wall, and through an old wood interior wall and I'll still have a signal. A weak signal, but still a signal.

I just went into my back yard and from about 65 feet away from the router (no line of sight) I was able to surf the web on wireless g. I get 3 or 4 bars everywhere inside on the same floor, 2 bars right outside the house, and it drops to 1 bar by the time I hit the trees. It's wet, I'm not going any further today.
It's just another data point to help you figure out if you have either a bad router signal or a bad tablet, because at 15 feet the gTab is able to get a great signal with an 'no frills' router. Everyone else seems to have similar experience.
@rajeevvp: Agreed. I got the impression he had a bad signal at 15 feet with a direct line of sight, but I may be mistaken.
mine works fine but the only problem that annoys me is that the wifi is always automatically turned off (especially when I turn the screen off and leave it idle). When I turn the screen back on, I need to go to settings and turn the wifi on. is there any ways to solve it?
wifi dropping
I am having the same problem with my wifi not automatically reconnecting after going to sleep. This happens if the tab is off for an extended period of time. I am running vegan 5.1.1. Any ideas???
thanks for your replies, I think I might go and get a replacement and check that out. The range of my device is about 15 yards through a couple of walls. I am in the US.

Set your "WiFi sleep policy" to "Never" in Settings > "Wireless & networks" > "Wi-Fi settings" > menu key > "Advanced", and see if that helps.

The Wi-Fi signal would only have trouble with the brick wall, then.
As for range, the maximum values for 802.11g signals are ~38 m (125 ft) indoors and ~140 m (460 ft) outdoors. In practice, I've found that these maximums decrease considerably.
Using "Wi-Fi Analyzer" I saw a received signal power of ~ -75 dBm 20 ft indoors (through a few intervening brick walls) at the other end of my house. I got ~ -85 dBm ~100 ft away from the back of the house and outside (through the intervening exterior wall and the low garden wall). And, at that signal strength, which is at the very low threshold of the wireless received signal power range, I was only able to see my wireless router, but, I couldn't use it.
At the other end of the signal-strength range, 2 feet away from, and directly in sight of the wireless router, I see a signal strength of ~45 dBm. This means that there is a drop in signal strength of around 3 orders of magnitude (1000x) from one end of my house to the other.

Nice--A tech-savvy pastor . But, he's wrong about Linux. Linux prefers to connect to the last access point you configured it to connect to (if it can see it). This is the correct behaviour--you wouldn't normally want the tablet to connect to some random access point or wireless router just because its signal strength was higher for some reason.

This tablet, bought Nov 2010, is very good on reception. It picked up 15-20 signals around any communities as we traveled aboard Amtrak from Philadelphia to Denver and return. It also saw a half-dozen signals (other than the in-house networks) when I was in a hospital for 6 days. I like WiFi Analyzer to see what's available.
Router
I have a few different routers (types) running here (Primary and Clients) for different reasons.
It seems to be router dependent (at least in my case). All are N capable. One stays connected all the way around the block when I walk my dog (yes, I walk my G-Tablet with us). One fades out if I am one house down. The other somewhere in between.
--You can try to reposition your router
--You could get another router, use as a client, or get a range extender
--You could log into the admin panel of your router and determine if you can increase the broadcast power.
--If it doesn't have this option and you are somewhat tech savvy (and have a compatible router), you could flash your router's firmware with DD-WRT (google it) or other similar. It should allow you to increase the broadcast power. You can look up your router on the website to determine compatibility, then carefully follow the directions to flash (standard-if you brick it please do not blame me or them)
--Hope it helps. That is pretty much all I know about this issue. Not sure where you are but the ATT DSL Router (that they provide here in the Bay Area, Cali) does not seem to have a very strong signal and is not (last time i checked) compatible with DD-WRT.
I've been reading for a while trying to evaluate the different level of Prime problems. My return window for the prime closes tomorrow. I'm an android kind of guy and I also own a Samsung Galaxy S.
I'm trying to evaluate the degree of problem with my GPS, WiFi and Bluetooth.
WiFi
===
Running wifi analyzer on both the prime and the sgs the signal readings are almost similar the connection speeds vary greatly with the prime often connecting at faster speeds. I have several wifi routers in my house for coverage with the same ssid. The prime seems to have a little more problems switching from one to the other but not that much.
GPS
===
My prime gps does work but the reception is much weaker than my sgs. This is especially true from inside my house. My sgs is easily able to see and fix 5-8 sats while the prime is completely blind. Outside the house but not in the city, the results are more encouraging with the prime being able to fix almost the same number of sats than the sgs but I cannot see the exact signal strength. I haven't tested in a city with tall buildings all around.
Bluetooth
=======
I haven't found any tools to evaluate the BT signal strength. I'm able to pair a headset and it appears to work properly but no other tests were made.
Soooo, my questions are: Was there batches of primes that were more problematic than others? Is the unconnected antennas problems random or related to the first batches? Compared to other working prime; is mine as good as it gets or I should roll the dices and try to find a better prime?
My serial number begins with: C1OKAS0xxxxx
Thanks in advance for any replies.
JF.
Sounds to me like you have a good one. Your wifi works well compared to your other devices LR even better. You have a working GPS. despite being weaker then your other device it works. Asus removed GPS spec so consider yourself lucky on GPS side. Then for BT seems like you have no issues. I'd think your device was a keeper. As far as wifi antennae issues, that's very random and very small in numbers compared to overall prime users here in xda. The biggest complaint is GPS, not wifi. The other gripe is some experience slowdown of speeds when BT and wifi are both streaming data. But you have alot also that don't experience that. So I wouldn't be too pressed about it. If your device works well, keep it. Or you could gamble on a new device. It could be better. But it could also not be. All primes no matter the batch has the identical same hardware. I have an early batch one I purchased on 12/22. Its been working great for me. Had no issues with it at all. So it is a hit or miss but odds are in favor of finding a good one.
Good luck on your decision. I'd say keep your prime if it works well for you. Its not a matter of if its as good as it gets. What you described your device as is a really good working one. Why take risk n get rid of it.
I don't think there are any "good ones", specially if Asus has to make a physical hardware change. UNLESS they are already manufacturing this change into production already, but I highly doubt that. A company like Asus could never move that fast.
The WIFI will always be an issue to some, and not an issue to most people. If you happen to be near a router (less than 50-75 feet away) you will be in good shape. If you are in a place like a school or office building where there are many routers, you will be in good shape. If you are trying to hold on to the edge of your routers max range, you will be in bad shape.
for GPS,
people are trying to get a lock with out a data connection. These tablets use the same GPS chip a cellphone would meaning it needs data connection for an accurate lock. You will NOT get an accurate lock using the GPS outside with no data connection. This is how all mobile devices are.
Thanks for the replies. I will sleep on it and decide tomorrow. I also have hopes that Asus will eventually do the right thing and replace the back of the prime...

With what, plastic? That is probably what is going to happen....
I have owned (and still own) ONE Prime. It works great. Wifi is strong or perhaps even stronger than any of my other devices in the house. I own a Playbook, Slider, Evo 3D, Photon, and some other random wifi devices. I was not even aware that there *was* an issue with the Prime and wifi until I started reading posts here with all of these issues and blaming the backing..etc.
I still truly believe that it is environment over the actual device. Wifi is a signal that must pass through walls, etc. I can bet there are times that the overly paranoid Prime owner sees his bar go down one notch and immediately posts up here that he is experiencing the famous "wifi problem". I do not doubt there are some people out there with real problems (such is the nature of electronics manufacture), but I also do not doubt that people overreact when they *think* its a "known problem".
No, I really like the spun metal back, and I'll be pissed if it gets reduced to plastic because of some kind of nonsense. Actually, I won't be THAT pissed...as I already own it
@zektor,
I was thinking more like the current aluminium design which is rigid and resistant but with plastic "windows" at the right places for maximal signals reception. A little like the iPad's solution.
I'm also learning to live without 3G built-in with my sgs wi-fi tether but that another story.

Sorry, but this simply isn't true.
I very frequently use GPS on my Android phones for GPS navigation when traveling overseas, and most of the time I am not using mobile data due to the exorbitant cost when roaming.
This would not be possible without an accurate lock.

Dave

Assisted GPS, using a wifi or 3G signal to assist the GPS location only allows a slightly faster location fix. After the GPS gets a location fix, it's not used at all. GPS signals from the satellites are very weak, and metal and water will block them. If you're inside, you simply can't get a good GPS signal. Moving a few feet one way or another can make a big difference, but not always. Being outside is essential for getting a good GPS signal. It's also essential that you don't put your hand over the antenna, because the water in your hand can completely block the signal. Holding the tablet in any position other than horizontal, facing straight up, can also degrade the signal, since the metal case blocks it. Putting a metal case over a GPS antenna is a bad idea, and after Asus did it, they had to decide whether to keep the metal case or make the GPS more usable. Fortunately, IMO, they decided that the metal case was more important than the GPS, so they just dropped the GPS specs from the Prime. Asus does not guarantee that the GPS in the Prime will work at all. However, the latest update, .15, seems to help the GPS reception a lot.

i know this have been discussed before but there is still no solution.
here s my problem: wifi signal drops suddenly when i hold my phone. ive done sevral speed tests. These tests confirm that holding the phone results in a really bad wifi quality. I ve tried eveything.
does anyone have any ideas? even if its hardware moding
thx
+1
Sad to say, in my tests, by tightly holding the phone, especially at the bottom right, the signal strength reduced by about 20dBm.
Sent from my XT910 using XDA
this really sucks since this phone is pretty good and so far its the only BIG problem i found. and no solutions....
Must be a random problem. I have the RAZR and RAZR Maxx and neither has this problem.
For me, on 2.3.6 wifi signal was low, especially taking phone by bottom, but on ICS, both t-mobile ics and latest eu ics, wifi signal is very improved. Hand issue remains, but signal is for me stronger.
well i guess im just going to wait for stock ics update and hope it improves but im guessing the problem wont disappear since this is clearly a hardware issue. and if this is random then im very unlucky
When software fixes a radio that software usually just makes the signal-strength meter show signal that's not really there.
There are apps on Play that "fix" all kinds of radio problems by installing signal-strength icons with the low-strength indications set inaccurately. It *looks* like more signal, but it's the same low signal you had before.
Signal strength has almost nothing to do with reception anyway. Signal/Noise ratio is what's important, and there's no meter for that. One bar of signal in a very RF-quiet area, is much better than five bars in a computer data center.

I have no wifi issues with this phone. The GNex however was unusable at 30 feet from a high-powered Hawking WAP, or an Apple Airport Extreme WAP.
If you have a plastic case, try removing it. Some cases are made with recycled plastic and are infused with conductive material that can act as a Faraday Shield, blocking part of the signal. Easy test, costs nothing but a few seconds...
yea i already knew about the plastic thats why i bought a rubber case. I have to say it helped a little but didnt fix it. the problem is still there.
thx
Haven't seen any problems with my wifi, although I mainly use the 3G simply because I have 4 GB of data a month and I will never use that much when I'm out around town.
If the problem occurs when holding it a certain way wouldn't the simplest solution be to not hold it that way, also be very aware of any metals between you and the router as metals block radio signals, how old is your house, if old enough maybe lead paint, unlikely but just throwing all possibilities out there.
thx for your help. i didnt only test this at home and as for holding the phone im used to hold it like i hold all phones and its pretty annoying if i always have to hold it differently if i want to use the internet
Have you tried the free Play Store app, WiFi Analyzer?
This will help you find out what works/doesn't as it provides more sensitive strength measurements from the chip. It's handy anyway, since it shows WAPs that you aren't connected to. yet.
It's quite possible that your antenna wire bounced off the connector. An insignificant drop of an inch could do that if it was never seated correctly. It would likely operate in a degraded capacity as a result. If you're OK with cracking the case open, that's something quick to check.
How long have you had this phone?
I have never heard anyone complain about the Razr's WiFi reception, so I suspect this is something unique to that phone right there. What is your idea of poor reception? 100 feet, inside, is the practical limit. 300 feet in an open field. Metal wall studs, sheet metal siding, all of these will stop radio waves dead.

Then you haven't been listening. The RAZR is universally acclaimed to have the worst WiFi reception of ANY device since 1999.
im ok with opening it... i actually opened it a couple of times and removed the battery but idk what to look for since nothing is labeled i dont even know where exactly is the wifi ship and antenna. i tested this as close as 6 feet from my router when i leave it on the table i get full wifi signal and speed test at max then i hold it and try... wifi signal goes down and speed test at 3/4 max speed...
thx
It's possible that I have an extraordinary phone then. I decided to compare.
My phone is seeing -60dbm from the Hawking extender that I'm closest to, which is about 20 meters away, behind three stick-frame (pine 2x4 studs, sheetrock) walls. The reading varies dramatically, depending on where I put it on my desk. So let's see what some other WiFi devices do...
My MacBook reads -58dbm. My iPad2 reads -59dbm. An HP Envy 15 reads -65dbm. And a Moto Atrix2 WCS (With Cracked Screen) reads -61dbm.
A transfer of 200MB ("random" data created via linux: 'dd if=/dev/random of=200mb.dat bs=1048576 count=200' so that compression algorithms don't skew the results):
Razr (6.12.79 ICS Black Widow): 9s
MacBook (Lion): 6.5s
iPad2: 10s
HP Envy 15 (Ubuntu 11.10): 7.5s
Moto Atrix2 WCS: 10s
I didn't repeat the test, and that is a busy WAP, but the results are what I expect for battery-operated devices. I also expected the ipad, atrix and razr to lose the race, since they have relatively slow storage systems, which have inherently poor write performance on files of this size (200MB won't buffer at all).
The WiFi cable will look like a white or black wire with a gold junction on the end where it meets the motherboard. I would expect that if you've had the phone open, you would definitely notice a wire hanging loose! I doubt that's the problem, but that wire is a coaxial shielded cable - like on cable TV only really tiny - and you can do all kinds of DIY replacement antenna stuff eg, adding an external jack so you can "beam" WiFi a mile away using a hacked Pringles potato chip can.
I actually think the problem might be RF noise in your environment. Florescent lights (CFLs), computing equipment, HVAC compressors, and motors can effectively "jam" WiFi signals, causing packet transmission failures to increase rapidly as the distance from the WAP increases.
We have a Fluke RF analyzer here, and our WiFi setup is quite good as a result.
Does anyone know if the Razr is unusually susceptible to RF noise? Maybe noise that the Razr generates from the motherboard/CPU/radios/BT? I'm not equipped to test that.
---------- Post added at 09:15 AM ---------- Previous post was at 08:29 AM ----------
Do you have other devices to compare the Razr to?
Did you try pointing all the rubber duck antennas on the WAP straight up?
I just checked an iphone, another ipad, another Razr, and a Dell laptop, and my boss's Razr was technically the winner on signal strength and transfer speed, but let's call it even. There are too many variables, and statistically significant benchmarking is beyond the scope of a forum comment.
The Razr has typical WiFi performance in this environment.
Thank you very much for your post. I did try with the desire z and the evo 3d which are doing jist fine wheather i hold them or leave them on the table: both signal and speed test are amazing compared to the razr (if i hold it). If you could tell me where the wifi ship and antenna are located (a pic maybe) it would be great because when i open the razr all i can see are metal plates everywhere probably for cooling. I dont understand what you mean by pointing all the rubber duck antennas on the WAP...
Thx again
I haven't had a Razr open yet. Even after dropping mine from a motorcycle and watching it slide into a ditch with an inch of water in it. Tough li'l bastards...
The WiFi antenna cable and connector are probably under one of the metal shields.
Most WAPs have 1, 2, or 3 "rubber duck" antennas that you can move to maximize the signal lobe pattern. You can use the WiFi Analyzer app to adjust them, but be prepared to walk a lot...
Others are just a box. The only one of those that *I* know of that works well is the Apple Airport Extreme. The Netgear Wireless-N HD, which is very highly rated, is a P.O.S.: it has a narrow, elongated lobe pattern, and if you're in that narrow lobe, it works REALLY well. If not, you'll be lucky to connect to it. Two people standing 10 feet apart, and one can have great service while the other can't even get an IP address.
The fact that you have other devices working well, and you sound like you've done this quite a bit, I'm guessing you have a problem inside the phone itself.
I manage about 200 phones here, and I haven't heard one word of complaint about WiFi. 3G/4G service? Yeah, lots of complaints about 3G/4G from people out in the woods or working in a valley.
These also work well as a WAP (tethering). We have a few of the Personal WiFi devices - a handheld that converts 3G/4G to WiFi for up to five users - but most people prefer this phone for that.
My old DroidX has a better WiFi antenna, but that's an exceptional phone with only one core: I spit on it. Ptui.
