1-2 months ago my nexus 7 fell from my hand and it has a small dent in its left top edge. Since then (not sure, noticed it first time 2-3 days after that happened) I have noticed that my N7's WiFi signal has been very weak. The router is 15-20 meters away in some other room and I used to get 2/3 bars in my room and it was basically just great, never had problems with WiFi before. But now I get 1 bar mostly, 2 bars rarely, sometimes I get no bars (WiFi still works, as per usual belief there are not 4 levels cause there are 4 bars, there is also a 5th level of WiFi on android with no bars, fully grey WiFi icon in status bar but WiFi still works but very slow and weak) and sometimes it just disconnects and I have to manually reconnect it in settings or wait some minutes for it to get reconnected.
Something weird I have noticed is that I get normal (like it was in old and normal case, 2-3 bars and no drops and choppyness) WiFi signal sometimes when I have held the tablet in portrait but as soon as I rotate it to right, signal jumps right back to weak (1 bar or no bar or disconnects even) and when I rotate it to left it also jumps to weak (1 bar or 2 bars or no bars) but not as weak as when I rotate to right (upside down is also similarly weak as left side).
Earlier I used to think its software problem cause I believed that if WiFi chip has been damaged then WiFi would have stopped working altogether but now I am pretty sure its hardware damage since I have updated through many night lies of cm10.1/10.2 and I have even tried absolute stock 4.2.2/4.3 and wiping many times. I have also tried many kernels.
My device was bought from US from office max by a relative of mine. I live in India and since the bootloader is also unlocked I doubt warranty will work.
I need help to decide what should I do, it wouldn't have been a problem it signal was just a bit weak but speeds slow down and sometimes WiFi disconnects so it is a problem.
Is there something I can do myself? Should I contact Asus support? The thing with Asus support here in my part of country (my city) is that they take long times to process things.
And also I want to know if someone has any idea how much it (the repair, if any) might cost.

It sounds like you have probably damaged the wifi antenna.
ASUS warranty support doesn't cover customer damage, but non-warranty support ought to be able to repair it. I don't know how much they would charge, but you can ask them.
It's possible someone with more hardware knowledge could tell you how to troubleshoot it yourself, but I don't know how.

Hey ppl, had my HD for about 2 weeks now and im loving it, soo much better than my N95 8gb, however I do miss the camera..! Anyway back to subject, today i went down my garage to work on my car (dont worry the phone was put well away from where i was working, have got it in the silicone case and its been very well looked after!!!), the battery was on 1/3 and in the space of 2 hours the phone was dead (not sure when in those 2 hours it died!) so plugged it in, let it charge a little then turned it on, now im having massive problems with the phone not connecting to the network???
I live in a city and as such never ever have problems with coverage, its always at max, however the phone will connect to the network with full signal strength, then within 5-10 seconds the signal strength goes down and down, then i lose connection all together for a few mins then it will reconnect at full strength again????
I've not really installed any apps recently, the only thing i've installed which i can think may have contributed toward something was HDtweak but it was all working fine yesterday...
Reallllly confused and frustrated, hoping its not a hardware issue already
Andy
right ive gone through all the settings, even hard reset the phone, still doing the same so it's got to be the phone itself... whoopdedoo
Did you ever sort this out? it seems I have the same issue, when the phone goes to 'sleep' it disconnects itself from the network, I wake it up and within a minute or two it reconnects back at full strength....meanwhile im missing calls....
I hate to ask this........if its in another forum or not but do you guys have the same problem running your internet when you are on edge. What sucks is my house switches from H to E and when on E there is no action. If there are others let me know cause I this is my second phone already due to black screen.

I get internet access on edge... it's slow but it works.
I'm having the same issue with the edge... I'm in Salt Lake City, where are you?

Same here, in southern Arizona. This is also my second phone. First one bricked mysteriously I can't access the app store or do ANYTHING data-related in EDGE mode. 3G works very well, but I get nothing whenever I'm in EDGE. At least I have wifi at home.
I've called customer support and their recommendation was to do a factory reset. I tried that, no improvement. I get slightly more stable connections after changing my radio to GSM (auto PRL) in the phone information menu, but it's still awful.
I'm thinking of calling back again in a week or so and bugging them to give me a third phone. Maybe the second batch with tighter hinges will be out by then...
I am on my third G2 and all of them have had much the same issues. All have had loose hinges. The last one I received started out by rebooting on its own as I charged it. With my Nexus One and my Vibrant I always get 1-3 bars of 3g with the G2s I get virtually no H consistently or 3g and 2-3 bars of E or a lot of G. This last one will go from suddenly having 4 bars of H to 1 bar of G it just does not stay on H and I get numerous No signals. Getting on the market at times is frustrating and downloading is a real adventure. I like the phone but am becoming disenchanted as it seems with this last G2 I am uncovering different problems every day. I have had black screen freezes random reboots etc. Also while in a conversation on the phone it put the call on hold without my doing anything. Perhaps the sensor malfunctioned and my ear hit the hold or mute button but this should not happen. I have also dropped calls and have had calls come in with no notification except for notice of voice mail after the fact. I am about ready to throw in the towel and send it back for a refund. If anyone has any ideas or fixes for any of the issues I have mentioned I would greatly appreciate hearing them
Just had a screen freeze and when it booted backup by itself it just went into a loop of home screen to black screen and home screen to black screen. Had to power off and pull battery and reboot and it now seems okay. That probably does it for me. I am tired of the constant problems and after 3 devices all with similar or same issues and more being uncovered every day,I am coming to believe that another replacement will not be the answer.
Yes this happens to me pretty often. I live in a building in Brooklyn NY, and when I am moving around in the building, my data connection goes out and I get 5 bars of signal but no data, no G, E, 3G or H+.
Also if I'm in an area where data connection or the signal is spotty, it will go from H to E and then back to E, and then give me a error about not being able to get any data connection.
i noticed that every few seconds or so the wifi icon would go all black, no bars, and the connection of whatever i was doing such as browsing would be lost.
when i did some searching on xda it seems most people believed that it was to do with their routers but one person said it was the antenna being connected to the case at the top left when in portrait so if your hand was holding it there, that would cause it. i held it elsewhere and no drop out.
if i put my hand back there, it wasnt instantly dropped but after a few seconds it did and when i removed my hand again not instant but the signal came back.
anyone else experiencing this?
i just ordered a case that i wanted anyway, will this maybe help this issue also as my hand wont be directly touching that area?
if I put my hand over the top of the device while in portrait view the signal drops down a bit but I don't lose signal.
I've never actually lost signal while in a covered area. At home at the farthest distance from an AC point, I still have good signal w/65Mbps connection.

cheers.
there is a definate drop from 3-4 bars down to 1-2 bars within 1 second of putting my hand over that location. if at the same time there is maybe something else downloading on my PC or something similar, that causes that last bit of a problem and the signal drops.
You're holding it wrong!
Lol jk I have the same issue too. This tablet has the worst wifi reception of all times... Of all times.
I'm seeing slight issue at 11.g, would probably be accentuated at a further distance from router.. perhaps an external mod, foil under tape?
What does the black dot on WiFi icon indicate?
I experience this exact issue. My router is at the top of the stairs on the 2nd floor. I can sit on the couch downstairs about 20 feet away and this happens all the time. This may be the type of antennas and or software these companies are using in general. My wife has the same issue with the galaxy tab 7.7.
My iPad however reaches through the whole house including from the basement and never drops below the max 4/4 bars on either a 2.4 or 5 Ghz bands.

I remember reading that apple had some top notch experts working on antenna designs during issues with iphone reception. The rhing is I can get great speeds with good reception, so it must be antenna proficiency that is the issue.
I have this issue too
I have this issue too but I'm not certain it has anything to do with the the way I hold the tablet.
It's really annoying, and I don't have a clue about what the cause is. Like thevuman said, worst wifi reception of all time, of all time.
Wifi channel?
you could try changing your wifi channel through the routers settings because interference may be the problem.
the below app can tell you the best channels to use though my router tells me to not use channel 13 and 14 because it might be incompatible.

I used wifi analyzer like you suggested and ended up changing my channel and killing the guest network, and it hasn't dropped again, at least not like it used to. So yeah this looks like a good fix.

So I may have ****ed my Wi-Fi Antenna or hopefully some sort of software setting.
I tore down my Note 3 to examine the ear-piece cause it stopped working. However after putting everything back together again, I noticed the Wi-Fi range has DRASTICALLY reduced. To the point where if it is more than 2 meters away Wi-Fi will not work. However if I am right next to the router it works swimmingly.
The Wi-Fi reception signals reflect this as well. Used to get okay strength from everywhere within the house (even upto 10m away through bricks etc) and now pretty much range is useless.
Was wondering if anyone else had experience similar problems after tear downs? and if maybe there is a setting that auto resets when you unplug the antenna. I had absolutely no problems when disconnecting it and looking at the headers again, they seem to be okay.... no physical damage noted. Just wanted to get some opinions before i get a new replacement that may not even help.
Did a factory reset 2 months ago.
main issue is it will hang on any web/page/link with 1 bar signal. A few seconds after turning it horizontal, it will get 4+ bars and behave like I turned on cell data and continue. I can't use the phone all the time in horizontal. Keyboard app is very big and uses almost the whole screen. From covid my stress levels are through the roof and have very shaky hands. I was admitted to psychology ward from too much stress a few. Months back
Anyone have this problem?
Will factory reset. I use work wifi with no issue at all. Never hanging or no internet working. Might be an antenna issue. I'll try to pay attention but outdoors no issues. Indoors seems to be the issue. I've captured this with another phone. Ironic... I hold it vertically and it has 1 bar and hangs....turn horizontal and it goes to 4-5 bars and internet kicks in
