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.

[Q] bad reception

Hi all,
i replaced the screen of my HOX when it got cracked.
i replaced it myself with a new screen from ebay.
the screen works well but after the replacment i have a really bad cell reception.
mostly i only have a gsm signal, a 3G signal is rare.
inside a house or building i have no signal at all.
i opened my HOX again to check the coax cable but this was not the problem.
can anyone tell me what hardware parts take care of the signal from my provider?
thanks.
nobody?
is it possibly that the two connectors circled in red are responsible for the provider 3g signal?

Weak WiFi Signal

Hi guys!
Suddently, my HOX's WiFi is weaker then before... When I put the phone near the router, the WiFi signal is very strong, but when I put it at 2 meters from the router, it goes down a bit, I have 4 on 5 signal bars...
What's the problem?
I think it's not a ROM-related problem, because I changed some ROMs, it's the same...

Just saw it... What a great luck!

Poor WiFi signal Tab 3 8.0

Has anyone problem with WiFi reception. I have only 1-2 bars when I am 1-2 meters away from wifi router. When i come to onother place my wifi signal is loss.
Is this known issue or I have faulty tablet.

WiFi strength, range, and throughput

Rate this thread to express how you think the OnePlus 3's Wifi performs. A higher rating indicates that it has excellent range, throughput, and signal strength. Like when you're taking a dump in the bedroom upstairs, do your videos have to buffer or do they come through without interruption?
Then, drop a comment if you have anything to add!
wifi is bad. check wifi anlyzer put hand between router and phone camera and watch how it gets lower and lower as time passes. really sad
As i can see in YouTube wifi speed can't reach any further than 70MB/s. Why? Software? Or wifi chip sucks?

Using 5ghz I'm getting nearly 200Mbps download on my OP3. Haven't tested 2.4ghz yet.
Here are the WiFi Analyser screenshots with and without hands over back cam. I was sitting very close to the router (~1m).

Can anyone confirm this? Thanks.

I just tried it out, the WiFi signal was getting worse but not as worse as in his video. Still somehow ****ty.
Didn't the iPhone have a similar problem? People's hands were shorting out the antennas causing dropped calls, etc.
A simple case should fix the problem (really, why wouldn't you use a case anyways?). And if you don't want the bulk or whatever you can try one of those full body screen protectors, should solve the problem of shorting the antennas AND provide scuff protection.

3.1.3.
Here's a test I just ran...Netflix is streaming on two screens right now, so it's a touch lower than usual.

My router is downstairs and I am upstairs. OOS 3.1.3. 5ghz.
Absolutely terrible...Always drops out
Wifi is doing pretty okay here on 5Ghz, its dropping sometimes though.
On my previous Nexus 5X I've had much better Wi-Fi reception.
OP3 gets about -8 or -10 more on Wifi Analyzer compared to my OPO when held side by side, definitely a bit worse.
Yeah. I noticed that OP3 under wifi doesn't work really well. Infact with just 1 wall in middle of me and router the signals drops from 20mbps to 6mbps.
Bad, really bad!
Nowhere near as good as my OnePlus One, disappointingly
Yes, if one wants to point out THE one weak point of the phone, it's not the display, it's not video recording - it's clearly the weak WiFi.
Honestly I feel as if my wifi speeds have been stronger than my note 4. 5ghz is nice and speedy
My OnePlus 3 is also giving the signal strength problem, sometimes it shows only 1 bar within 2-5 meteres from the router.
