Weak Wifi signal on stock

I am using 4.0.2 stock version and wifi signals are pretty weak. Is there any tweak or some settings i can flash to get better wifi reception . . .

I am having the same problem. Out of 5 phones in the hotel lobby (HTC Desire, HTC Wildfire, Iphone 4 and Nokia N97) my Galaxy Nexus had the weakest signal, and sometime even lost the wlan.

I notice wifi signal drop when i cover the top part of my nexus with my hand
tested in speedtest, it also shows slightly lower signal bars, are you using a wireless N router?

Try flashing different basebands to see if signal improves. Also, I recommend franco's milestone 2 kernel since it has a setting to amplify your wi-fi signal (at the expense of lower battery life)

I don't have this problem in fact my wifi speeds are insane

The WLAN antenna is to the middle right of the phone when you look at the display in portait mode.
If I make sure that area is not covered by my hands the reception is quite ok with my Nexus.

I took an old router and made it a repeater bridge, problem solved.

I find the radio on the phone is quite weak to begin with. iPhone lasts much longer out of town where I live.

GPS Dropping

Does anyone else have this issue? My GPS loses connection to the satellites every couple minutes. And yes, I have the latest map update.

Must be the bug in update. Try to use 3rd party app! Just because i never updated mine, and is working like a charm

The GPS in my phone is not very accurate. Maybe its just this phone. I only get relatively good GPS reception at night.

Thanks guys. I'm starting to think it may just be this phone as well. The first map told me I was 3 miles away from my house....lol...and the second was accurate but keeps dropping the signal. I do have carhome. I'll try that and see what happens.

I also have this issue though the GPS (which is used a lot by me) was quite OK in the beginning after I bought my LG OG PRO.
I read in one of the Samsung NOTE forums that people mention the same problem claiming that the drops come when there is an "interruption" (which can be an incoming call or SMS or switching from 3G antenna to 3.5G for example). After reading this I realized that my GPS gets lost always after an incoming call plus I see at least a couple of places along my daily driving routine where GPS is lost exactly at the same place every day (making antenna switch assumption logical).
There were no any conclusions or suggested solutions in these forums, people even do not know if it is software or hardware related.
Anyone has such an issue too? Any recommendations for possible fix?

I can't believe but it seems I solved the problem with GPS - 15-20 seconds for GPS lock, no dropping and GPS test application shows very nice picture of 8-9 satellites constantly locked up while most of the signal bars are yellow (i.e. the signal strength is good).
I searched a lot as it really bothered me because I use my GPS very much plus I can say that beside this annoying thing I am very satisfied with my LG OG Pro, but nothing helped until I found this video: https://www.youtube.com/watch?v=QBpNtWvY454 (it explains the solution for Nexus 5, but my problem is identical)
Basically, the problem is that there are special contacts on the motherboard connected to the GPS antenna which is part of the back cover and the contacts are not tightened well to the GPS antenna (look at the attached picture where I put the red arrows at the relevant places). Due to the bad touch between the contacts and the antenna, the GPS does not work properly. So, all you need to do is to remove your back cover, gently "un-glue" the GPS antenna end (the rectangle part on the back cover containing 2 golden dots), lift it up a little and put a piece of paper that will tighten the antenna and mother board contacts when the back cover is returned. Good luck.

It is NFC Antenna, you cant fix GPS this way.
I have same issue, but i think NFC and GPS antennas are different. I am disassemble the phone and pull up all golden springs - but gps still very weak(((
Any solution?

same GPS problem for my g pro.
GPS is weaker and weaker

I realigned all the pins inside the phone and fixed it for a bit, but the signal was still weak. I figured it was the modem. I installed a custom rom and it worked like a charm!

[Q] Wifi detection range and signal huge decrease

Hello. Recently, I opened the back cover of my note a couple of time to reattach the loose LCD ribbon in my tablet. During this time, Isomehow,noticed that the wifi was not working! Well, it was working, but I cant use my device unless im < 10 feet away from a router. However before, it was working perfectly fine, and on my other.devices, everything is fine. Is this a well known problem? Did I damge the internet card in my tablet? Also, the signal is around -60 when im close b
ut when.I walk 10 feet away it is like -90.

I would imagine you have disturbed the Wifi antenna. I haven't seen inside the tablet, but it would more than likely have at least one antenna connected to the Wifi module.
It's usually a thin wire running on the outer frame.

My tablet can not see my wifi router when it suddenly shutdown.
I don't know why my tablet never see name of my wifi router if suddenly turnoff wifi router. I used WP2 and AES & TSKIP.
And if want my tablet P600 see my rounter wifi, i must go to wifi router setting to change AES or TSKIP and then my tablet can see it. But my galaxy s4 don't have this problem. Maybe kernel of galaxy note?

Extremely bad wifi range after installing cm11

So I have a problem with the range of my wifi, my ipad mini will say it has full signal but with my htc one x, even when it is 2~3 meters away from the router it still wont say it has great a signal. This wasn't the case when it had its stock rom. Any ideas?

[Q&A][i9195] Low wifi connection.

So in one room in second floor there is 1 bar wifi. My i9195 disconnects after sometimes and have to wait until it connects while others have no problems. With other phones (s2, lg 70.....) it don't disconnect and everything perfect. Even they can brows in third floor and for me no chance to connect wifi and browse etc. Is this problem with phone or this phone has bad anttena? If someone has same problem with i9190 please respond is everything Ok.

I recently got S4 Mini i9195, and noticed same problem, wifi was absolutely poor. I started searching on the internet, found where the antenna is, and decided to take my device apart. And you wouldn´t believe what I found.... all other antenna contacts on motherboard are bent, they are in a ˂ shape - so they can flex and touch antennas integrated in middle frame chassis. Wifi antenna contact was absolutely straight, parallel with the MB, so there was no way it can touch antenna on the chassis. I used needle and carefully bent the contact in correct shape, assembled phone and voila - wifi signal is full.
It seems it was a production error, I´m surprised nobody noticed it before.
