Poor wifi signal

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.

JB 4.1.x wifi range/signal (GSM GNex)

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.

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

My Experience with Latest Radios (VZN FF02/FG02)

I know there is a thread for the latest system update but I thought we should have our own thread to discuss radio experience.
For me it's nothing short of amazing! I am such a happy camper right now. I work in a brick building and I could hardly ever hang onto a 4G signal. I would say the phone was staying in 3G 90% of the time and 10% 4G.
Flashed the latest radios and over the last 4 hours I have had a solid 4G signal all day! I can finally use my 4G signal at work! It's been horrible because we don't have wifi in my building. I have heard that handoff between wifi and 4G is quick but I havent been able to test yet.
How's everyone else's experience?
I say go flash this now! http://rootzwiki.com/topic/33228-jro03o-radios-for-toro-ff02fg02/

Nice. Thanks for the quick link. Didn't have to read through the other forum to find it. At work downloaded the zip on my phone, flashed through cwm and boom. New awesome radios

That's all I have to say about that. I know speed test is not reliable but its something.
Sent from my Galaxy Nexus using xda app-developers app

Damn! Especially that large of a jump! I haven't even done a speed test...I'm just glad to be able to even grab 4G haha

Everything is so much snappier now. My signal strength stays at four bars constantly too.

I unfortunately didn't get any speed tests from 4.0.4 radio but I did do the latest from 4.1.1.
Not sure if I should be happy or sad?

Very, very happy with the new radio release.
I was one of the many unlucky Nexus users with the 4G/radio drop, and had been resigned to using strictly 3G in order to simply have a usable phone outside of being on a WiFi network. For such a good phone, this issue had me literally hours away from finally returning it back to BB since it is w/i the 30 day return window and getting a new phone altogether.
After flashing the radios this morning, I have had no signal drops, constant 4G and no delays or hiccups of note. Whatever they fixed, hopefully it remains!

Yep, these are the radios it should of shipped with out of the box! I've been struggling with similar issues for almost a year!

I usually get a good signal in the building where I work and at home. I've flashed the new radios and haven't noticed any huge improvements. Nothing is worse either.

I flashed the new radios, too early for me to tell since where I am in NYC I always got 4G, but I just tried a few speedtests lucky if I get 5 Mbps
I don't think I have ever seen anything higher then that unless I am on wifi, how do you get such great speeds.

I just think the new radio show more bars but they didn't increase my signal or anything...
its -100dbm and I have full bars all the time

I live in reno nv so not very many people on the network as compared to NYC.

Nothing changed for me at all. I've always had a good signal going back to 4.0.2.

No noticeable change of anything here.

Wanted to echo what you said. I was in the same exact boat! I haven't used 4G in months because I would loose data constantly and people would tell me that when they called it would go into fast busy. I am now hitting 24 hours on 4G after the radio update and not a complaint! I certainly hope this is the fix:good:
Side note: I haven't noticed an increase in signal but as long as my data stays I don't care.

I've had a big jump in speed. I live just outside a 4G area and before these radios I would get about 2 bars and of was alright to use it, but used WiFi most of the time. Now I would rather use my 4G because its faster than my WiFi, lol.

I had a good first day with it, it seemed to hold signal at work better (which it usually drops in certain areas of building a bit). Still same visible bars and such...I'm not prepared to declare it better yet, but am optimistic that it will be an improvement for me.

Everyone has LTE phones here in LA no 30mbps for me.
Sent from my Galaxy Nexus using xda app-developers app

Same old same old for me. Constant data drops... 55 percent without signal time. usually 44 percent without signal on the older radios (house is built like a bomb shelter, literally) so if anything, its worse now.
bah humbug

Horrendous WiFi signal strength

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.
Sent from my Galaxy Nexus using xda premium

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.

Horrible Wi-Fi strength and speed

I really hope there is an update to the Wi-Fi driver. Comparing it to my HTC one, s3 and nexus 4, it always has a lot weaker strength and speeds which is a little disappointing since its WiFi only. Has anyone else noticed this? In many spots the Wi-Fi will not even show where my other device still have half strength. I LOVE this tab but this only one issue is bugging me

No, this has much better wifi than the Nexus 4. The Nexus 4 has wifi driver issues.

The Wifi in this tablet has been the best I have ever owned, laptops and phones included. The range is incredible. What I thought was a dead space in my home isn't with this.
Maybe you're holding it wrong?

This makes me upset. Maybe I have something defective. I'm def not holding it wrong. Is there any apps that judge WiFi strength

Yeah it's called the WiFi signal indicator in the top right of your screen. Not trying to be an ass, but that's what its there for.
I have fantastic WiFi on my device. I get better upload speed on it than any other device in my house.

Try changing the settings from Auto select to 2.5ghz only under advanced in WiFi settings.

I was going to test this and then I noticed it connected itself to my wifi a block from my house. I am very impressed to say the least !
