I've noticed my wifi reception dropping greatly as well as my cellular signal strength. I reflashed different modems and even went back to my regular one. Many times it wouldn't even regain the cellular signal at all. When I choose to search for network, it gives me an error.
As for wifi, I normally get almost full signal in all rooms of my house. Now I find I barely get reception and it completely drops at times.
I'm on Flapjaxxx's Cm9 rom if that means anything.
SOLVED: wifi antenna making poor contact internally. Adjusted spring contacts inside. All is well.

Flash a new modem that will boost signal in the carbon installer app

so no one else has this issue?
I walk 5 feet from my router and the signal drops to 1 bar.
I have this same issues ever since moving to CM9. My 5GHz N network is unusable. I'm five feet from the router with direct line of site and it's seeing about 2 bars (fair) and -70db. Moving 10 feet away moves it down to -80 or -90 and 19Mbps before it ultimately disconnects. I've tried reverting back to modems that I was successfully using on stock ICS, including UCLC5, UCLF6, and UCLE2, but none of them have made a bit of difference. Is there some other component aside from the modem that governs wifi?
My laptop and HTPC which uses a USB WIFI adapter and is about 20 feet away from the router have no issues getting 5 bars, and inSSIDr shows that I'm the only 5GHz AP in the area.
Anyone have any ideas?
Antenna issue? Perhaps an unlucky drop caused the antenna to become unseated?
It is possible to open the phone and push in the antenna.

Agreed.....
We've seen at least two other users this week with a loose antenna seat, that required a repair to correct the lost signal issue..
this may not be the problem, but certainly something to consider....g
I neglected to mention that my 2.4GHz signal works great, 4 or 5 bars throughout the apartment. I'll take a look at the antenna. I don't supposed there's a less warranty-voiding way of doing it than pulling up the sticker?
I'm seeing the exact same thing. as soon as I rooted and flashed a custom rom my 5GHz has dropped to virtually nothing. my cell strength and 2.4GHz are weaker than they once were but 2.4GHz and cell is still very usable. my 2.4GHz drops to 19mbps constantly. I've bounced my phone back to completely stock ICS and that resolved the issue, though stock rom just isn't fast enough for me anymore so I'm back on Paranoid Android CM10 Aug27 release 1.992
A couple of other things, I use AT&T, my router is an ASUS RT-56U dual band wireless N, I live in an apartment complex where 2.4GHz is saturated, but 5GHz is clear and I live roughly 1 mile from the closest cell tower. I run my laptops in 5GHz and my streaming media in 2.4GHz. So for all intents and purposes my 5GHz should be much stronger.
Any thoughts on why the custom Rom is doing this?
If I have time today or tomorrow I'll do a backup and try out a stock ROM to see if the problem goes away.
Yes...It sounds rom related at this point...
A stock rom test, "With" a stock modem would be a good test....g

Update. Rolled back to OEM ICS 4.0.4 and my wifi reception is MUCH stronger. Guess I'll be staying with ICS.

It seems I was wrong. I took my phone apart and checked out where the WiFi antenna contacts were. One of the springs was flat and barely making contact. I pried it up slightly and things seem better. I will update again if I am full of fail.
Just a tidbit:
On every one of my devices, with CM9/10 loaded, my 5Ghz signal strength is weak...
Sitting on stock, and my signal is fine for 5Ghz WiFi...
I said it back when CM9 was starting to become regular, it still hasnt changed...
Something changed in CM when CM9 and now CM10 came to be that 5Ghz WiFi now sucks very much badly!
The ONLY time I get full strength with 5Ghz is when my phone is sitting on my router, I sit maybe 3-4ft away (no walls, level, in-sight range), and it drops a bar sometimes two...
This happens on all my devices with 5Ghz WiFi and CM9/10, my HD2 (for example) on CM7.2 has matching 5Ghz performance with 2.4Ghz, but on CM9 its the craps :<
Update: yup. It worked. Full bars on WiFi in my house again. Even in areas where I had zero reception. Possibly a small drop caused the spring contact to be compressed.
Currently running. Flapjaxxx AOSPxXx ROM from Oct 23.

You didn't by chance get any pictures did you?

Unfortunately no. But its fairly easy to see where the WiFi contacts are when you open the case. When you pull the battery cover off, there is a pad/ sticker on the upper left. That's the antenna, right next to the power button and SIM tray.
NOTE: DO NOT PEEL ANY STICKERS/PADS OFF
If you take the phone apart, the contact pads are right under it.
When the housing/is separated from the screen (snaps off) you can see two gold springy contacts that look like the ones in the SIM tray. Like this > . If its flat like this _ just pry it back open GENTLY. Only like 1mm.
Then reassemble phone and test in a recently known bad WiFi area.
Mine is finally awesome again.
AWS cellular reception is still mediocre since day one tho.

Going out of the comfort zone usually has its rewards. Good job!
Hello everyone, this is my first post here. Awesome, I know. I was curious if any of you experience a weird wifi issue. I have full signal and the bars are indicating things are good, but I cannot access my internet from my bed. I can move about 5 feet towards the door and it works just fine. My old EVO 4G wimax has never had a problem, and could work outside even. Do you all think I just have a bad phone and I should return for another one, or is this maybe just a glitch that others are experiencing and i should just wait for a fix.
I have the same issues with, and without, the best wifi performance enabled.
I'm open to suggestions, as I really love the phone.
I have had this happen too. I don't believe the number of bars showing is correct. And that in fact the signal was weak.

You can try to disablr then reconnect again. Sometimes this helps. I also have mine set to 2.4ghz only and I installed wifi manager. I haven't had any wifi issues since. I hope this helps.

Try to set it to 2.4 only. My router doesnt like it any other way.

Does your router firmware show you the signal strength of each connection? I would leave your phone in the room that is causing problems and then check the signal strength. Also try this just to be in the clear:
Forget network on phone, delete and release lease on router (if you have it set up this way), reboot phone, reboot router. Now try to reconnect again.
The above is always worth a shot. Reply with results and we'll take it from there

Thank you all for the advice. I changed this to 2.4 ghz only and it works perfectly now.
I have similar problems even after the update that I though fixed the wifi issues. Now instead of it reconnecting like you said it shows connected and I have to cycle it on and off to get it to work. Very frustrating. Guess will have to wait for an ota again.

Hello,
I can browse internet only in room with router and near router rooms.
Will i able to use wifi in any room in house with this device(s) ?

thanks
Sv: Can wifi repeater resolve room wifi ?
Yes,it will help. I have one, but not same model and it increased a lot my wifi range. I can have my Prime connected to my house Internet with full bars anywhere I am inside the house. It is a very cheap solution as I got mine for something like $65.

Hi,
I am using the Galaxy grand I9082 Duos. I have a simple problem in WIFI signal strength, on this device signal strength showing very week for a distance of 3 to 4 meets away from the wifi router in the next room. But Laptop shows good strength at same point.
If I take my mobile close to router shows very good strength.
Any solutions please.
Regards,
Ramesh
It must be due to the router you used. I am using dlink router in my house ang my grand wifi is always full even I'm inside my room 2nd floor around 8-10m aways from the router.. try to use other type of router

I could have sworn I read a similar issue on here but can't find it now. I have an Asus RT-AC66U Dual Band 802.11ac router. Its supposed to be top of the line. Every other device connected to this router works perfectly fine except my z2. The phone shows it's always connected to the wifi network, but my Internet access randomly cuts out. I have to disable wifi and re-enable it for it to start working again. Usually only lasts a few minutes before it cuts out again. Very annoying. Does anyone know a fix for this? Perhaps a setting on my router?

I would like to know this too, same thing happens with my Z2 (I have a RT-N66U), oddly enough the rest of my devices does not suffer from this issue.
I somewhat fixed the issue.. I called Asus support and a technician walked me through the settings on the router. I still have issues connecting to the 2.4ghz frequency, but the 5ghz is fine. Only issue is the 5ghz signal doesn't travel as far as the 2.4ghz signal. I'm going to call Asus again when I return from vacation to see if there's a better fix. For some reason the z2 has issues connecting to some 2.4ghz routers.
