I can't seem to get a decent wifi signal unless i'm actually standing near the router (and even then it's 2 bars at most). I doubt it's the router (cisco linksys e2000) since my iphone and pc have no trouble staying connected while being further away. I remember having a better connection when i was using the stock rom (cm7.3 atm) so i'm guessing there's something i need to fix but im not really sure what's wrong and was hoping someone could drop some knowledge on me.

Hi there, This issue can be caused by a mismatched ROM and radio, each radio and ROM work together with a specific RIL (radio interface library) which can be flashed through recovery or CWM. You may find that the recommended radio for your ROM and the correct RIL could solve your problems.
The wifi signal on DHD is poor while comparing to other phones, I wish that we could modify its strenght.
Through a wooden wall and about 4-5 metres away the signal is around 65dBm, which is ok, but as soon as I move slightly so the the signal is going throught diagonally it drops to 80dBm instantly. That's only moving very slightly.
In my sig you can see what I'm using and so far that's the best combo I've found for a decent signal.

Iv read in a few places that in the newer versions of android (2.3.x) something on the WiFi signal strength was changed to -88 and a lot of el cheapo routers can't keep that signal hence causing the WiFi signal to drop out on your desire HD. Is there anyway to change this on the phone so it picks up the WiFi connection better and doesn't drop out / fluctuate as much?

The radio is what controls the WiFi signal. Different Roms will perform differently with different radios.
If possible always flash the recommended radio for each Rom.
I, however, have not changed my radio from the one the dhd came with. Never had a problem.
Some roms have an increased WiFi scan rate. I don't know how to perform this independantly though, sorry.
So to sum all this up. if your WiFi is dropping. Try flashing a different radio. Be careful though. This is the most risky process for bricking phones. But read plenty of posts and it should run smoothly. Hope this helps.

any solution?
I'm experiencing a fluctuating wifi signal even without moving at my desk. Is there any solution?
Hi,
I've been using JB since the version from io12 was out. Currently I use Bigxie's deodexed 4.1.1 and all is wonderful. Except one thing that is. The wifi signal is weaker than I'm used to from ICS. Especially the wifi range seems worse. Connections that I've used with ICS are now out of range. Some of my friend or family's connections are now very weak and I drop out of range very often. This goes for any JB rom/kernel I've tried.
I've tried several roms, trinity and franco kernels, dirty flashing, full wipe. I've even tried a couple of different basebands, even though I don't think they affect wifi.
So I'm wondering if other GSM GNex users are experiencing the same thing? I've seen a thread with a flashable "poor wifi fix" for the Verizon GNex, but nothing for the GSM version.
Verizon GNex wifi/gps fix:
http://forum.xda-developers.com/showthread.php?t=1739097
Any suggestions? Coukd a similar solution like the Verizon fix help?
Best regards,
P
Ok, allow me to explain whats going on with the "fix".
There were some folks who ported the GSM version to Verizon (myself included). However, they failed to use the correct wifi/BT firmware (I did but thats besides the point). They left in the GSM version. So that above fix is merely the bcm4330.hcd firmware and bcmhd.cal calibration file for wifi/BT from 4.0.4 for Verizon. It is not meant to be used for GSM and only applies to those who ported GSM to CDMA. Even with the fix, wifi is weak.
Verizon users currently have a newer version now, specifically for them from Google. However, the weak wifi issue still exists even for us. There are some who have strong wifi routers or are always close to them that do not see the issue, but it does exist for every JB user. Wifi is simply weaker, and BT is fairly janky.
It is a Jellybean specific problem, and I am assuming it will be fixed in time. You could try a 4.0.4 bcm4330.hcd, bcmhd.cal on Jellybean, but I doubt it will help, and it could end up hurting. I am thinking that broadcomm needs to fix these files.
Thanks for the reply and the precise info about the problem and the background for the Verizon fix. Very much appreciated.
I guess I'll have to wait and hope for an update.

I am right there with you.
Wifi is horrible!
WiFi does kind of blow chunks. WTF.

The more I think about it, the more I think it can probably be resolved by tweaking the calibration file. However that is a bit beyond my abilities as I don't understand whats contained in it to know what it needs tweaking to.
wifi weakness
I'm not sure why it does this but when I am in my house about 15 feet away from my router I would notice my wifi signal dropping down to 2 bars where my other phone would stay at full strength until I got around 15 yards away.. I decided to see how far I could get away from my router before completely losing signal. I walked a total of about of 30 yards from my router to the edge of my street and stopped every time the signal decreased down to one bar(which was between every 5 or 10 yards)... every time I thought the signal was about to drop out it would return back up to 3 bars after a moment of adjusting. Once I got to my furthest point it dropped out completely and then came back to 1 bar. When I came back inside where I previously had 2 bars I then had full signal throughout the house. I tested this a couple times and it seems that it only uses what it needs. If someone could do a similar experiment to confirm this isn't specific to my router set up I would appreciate it. I also did not notice any drop off in performance in speed from 1 bar to full signal while I was within 20 yards of my router, however, I didn't run a speed test, I just used my youtube app to load a video... I will run some speed test when I get home this evening to get a solid figure on the speed difference. This may not be a bug but a feature to conserve energy to increase battery life.

A good theory, but I am dropping wifi in some of my rooms. Switching to and fro like that doesn't save power
didnt people have poor performance with their wifi signal on ics? did broadcom leave everything the same of did they change/update drivers for our phones with jb.

Me too, I only need to move to the next room or so sometimes. The main problem for me is range. The range for me was better with 4.0.x.

ICS wifi performance on the GNex wasn't exactly perfect for me, but it was better than what I get with JB. My router at home is giving me an okay performance and range, but the routers I normally connect to at family and friends are giving me problems since I moved on to JB.
I believe JB does come with new drivers. At least I've read that it does, in other threads.

Wi-Fi has been fine for me, but only when using 2.4GHz—5GHz, on the other hand, is horribly broken. If you are using 5GHz, I recommend trying 2.4GHz instead—hopefully Google will have this sorted before the Galaxy Nexus II ships.
you may want to revert back to ICS to verify if the phone hardware is not a problem? otherwise for me I have used both... ICS and JB, and I don't find any difference..

I’ve found 5GHz to be broken on both ICS and JB and this is with more than one phone.

5 Ghz was fine for me on ICS. It works on JB too, but the range...ugh.
I'm pretty sure it's not hardware related. It's definitely related to JB. It's not a 5 GHz problem either, that's what I use at home on my d-link. Family and friends have both 5 and 2.4 GHz. I'm sure it depends on the quality of the routers also but I didn't have any real range problems with any of them before JB.

Same here, except my d-link at home, which is kinda okay at 5 GHz.

2.4 is pretty weak for me too.
I looked at the calibration file from ICS to JB. I don't think the difference warrants the problems seen.
From ICS to JB, these are the changes:
# 2.4G ACR
rxgaintbl100=1
# 5GHz Starting Tx Gain Index
initxidx5g=96
Even since JB, my WiFi signal is terrible. In my bedroom, my laptop gets 4 bars, my nexus gets 1. 10 feet from the router I get 3 bars. Is there s fix for this? I've searched and I can't find one.

I too get crappy wifi reception but I can't totally blame Jellybean for it. When I got my Gnex JB just came out so i did not have a lot of time to do a before and after comparison.
I just put a second router in my livingroom to help and sitting less than 10 feet I only get 3 bars on the phone. I hope we are not the only ones with this problem.
Even my GNEX has a bad reception ... I have the impression that it was better with ICS. But I would never go back. I subscribe maybe jumping out of a solution ...
I got the same problem with my GNex. No way to solve it and just let it to be what it is.
Which ROM's are you on? I'm using CM10 and have no problems with Wi-Fi signal in my apartment. Are you using 2.5 GHz or 5 GHz?
Swype'ed on my CM10 Galaxy Nexus
I am using Maddoggin's Jelly Bean Rom which was built from stock and not CM10, some people are saying that the kernel is responsible for the wifi and that the radios only handle the cellular and LTE signals hmmmm. His ROM is using the stock kernel so I may try flashing a different one to see if this helps or try different ROM altogether.
Sometimes when the phone is on the table in sleep mode, if I turn it on it will have like three or maybe four bars of wifi for a second then it drops down to two or one. Holding the phone in landscape seems to help with reception too. Maybe this is due to placement of the wifi antenna?
I have two Netgear routers in my house and I belive they are 2.4 Ghz, I have them on different channels so the signals do not overlap.
There maybe an off chance that the phone could be defective but before I head over to the Sprint store I need to do a little more investigating.
So I just got my Nexus 7 fhd couple days ago. I've noticed that it has very weak wifi reception. When I in the same room as router I have full signal, behind one door half signal, and behind a second 0 signal, on my laptop and iphone i get about 70% signal behind a 2nd door (it's probably only 15 feet away from the router). I'm running on Wireless N 300mbit 5GHz if it matters. I read similar thread for old N7 but didn't find any solution, wonder if anyone else have the same problem? Android 4.4.2. Thank you
Is there interference with other routers on the same channel?
Also noticed a teensy bit weaker wifi reception compared to 2012 nexus 7.

It's not a little bit, i'm 10 feet away from a router and have only half bars while all my other devices show full signal
Also i tried different ROMs
I have the opposite experience in that I get better reception with my N7 than any of my other devices. When I have had issues with Wi-Fi reception with other devices in the past, the only thing I found that would fix it was to reboot and reset the router. And oddly enough, once or twice the only thing that worked was to change the password. Hope you find a solution because this thing rips when you have a good signal.
