Just wanted to know if there's other people with the same problem as me because I only get one bar of WiFi signal when I'm close to my router or maybe 2 never 3.Just wonder if there's other people with a sensation having the same problem. Also I sometimes us sense based roms and they give me full WiFi bar signal all the time so I have no clue what's happening.

Is the low signal causing a problem or does it just look low in the status bar. I often find when switching ROMs that the "Strength Indicators" vary but when I switch them to show me the readings as text (dBm) the signal strength is fine.
Maybe you could try installing an application/widget which shows you the signal strengths with more accuracy than the status bar icon can portray and you may find that its all ok.
I have always found the wifi signal to be fine on all cm and aokp ROMs I have tried.

I do look at the WiFi bars but it is causing problems all the time I sometimes loose signal or I get bad signal

I do look at the stock WiFi bars but the WiFi signal is a problem because Im sometimes close to my router but it only shows 2 bars of the three and where parts I should be getting great signal I'm not

Dear all,
I had the 8.0 rom installed and everything was working fine, (excellent rom by the way!).
Since I instaled the 9.0.2 my wifi signal strength keeps changing from 3 bars to 1 bar and so one, it never goes full strength and is never constant.
Can someone help me on this issue?
P.S. Darky, thanks for your amazing and tireless work!
Have almost same problem. In room next to router i had 3 bars signal strengh on 8.0 and now on 9.0.2 i have only one bar, sometimes there shows second, but for a few seconds only. Did u report in at darky's rom forum website? If yes, what was the answear?

I did report, but until now I have no reply...
No one knows what to do?
I get a very weak wifi signal after flashing.
40 dB...... pre flash.
60 DB........after flash from same location ( 4 feet from router.
Any ideas?

Try out nexus beam the wifi signal is better for me

Yes I can back that claim up
From what I can tell, its all snake oil and Pygmalion effect.
The chipset is the same. All that has changed is the number being reported to the UI.
If you fire up something like netperf I'll lay money that the throughput on the link is just about the same for any of the available ROMs.
The "signal strength" reported by the chipset is "RSSI" Received Signal Strength Indication -- it isn't calibrated in any way for consumer devices other than to make the UI look good. The link speed isn't a good indication of throughput either.
I'm sure you are correct. But where I used to get 6 available AP's, I now only get 2 with much weaker signal. My 5 ghz guest network will not even show up at 15 ft from router. At 5 ft away (with no obstructions or interference) I get 25% signal. I'll test throughput, although throughput seems excellent near router. Almost seems as if Rx power is low. I lose AP's at half the normal distance. My gs2 picks up the same AP with 75% signal, from the same location.

The signal definitely is weak for me despite what people say. My wifi disconnects in places where it used to work fine before (for example when on my bed with gingerbread I would be connected with 1 bar, but with ics its constantly disconnecting and reconnecting at 0 bars

Did it show up under GB? I've never seen my high-band 802.11n at all, but I always assumed it was that that I was using the wide-band modulation. If it was showing up, are you using 20- or 40-MHz channels?
I'm definitely interested in finding out if we have lost functionality going to ICS.

This doesn't surprise me. Internally, in Java, the "bars" are set to be 4 between a reported RSSI of -55 and -100. Stations that are below the lower threshold aren't reported in the UI. It appears to me that ICS ROMs generally report a RSSI to the Java world that is ~10 units lower than GB ROMs do.
frameworks/base/java/android/net/wifi/WifiManager.java
You might want to try
Code:
# wpa_cli scan
# wpa_cli scan_result
to see what the driver is reporting.
I've been tempted to just add 10 in the framework and enjoy all the reports about how much better a ROM it is.
I still need to get netperf onto a GB ROM and do a little more testing. I think the sad answer is that the RF design, in general, is not good on the SGS4G, resulting in both poor WiFi and GPS performance.
Testing with netperf shows that the stock GB rom displays about "one bar" more signal than ICS AOKP. In this brief test (five, 10-second runs for each AP) the throughput for a relatively weak AP is about 10% lower for ICS than GB. However, the throughput for a strong AP is about 10% higher for ICS.
Conclusion: WiFi measured performance is comparable between GB and ICS.
I take it back..... 5 ghz network missing issue was on my touchpad. I get mixed up sometimes.
wireless range is poor , but in my small house it works. even a weak signal on this rom seems as fast as good GB signal.
This rom is otherwise awesome!
Thanks for your help

I'm the area i live att has good service also where i work and around my town. I used to get full bars in my house, good bars almost everywhere i went. This all changed after i installed the leak. I know get 1 to 2 bars almost everywhere. Nothing else has changed in my phone or my life. What can be causing this and how can i fix this?
Anyone else that installed the leak had any problems like this?

I dont think much has changed signal wise. I do however notice wifi is amazing on ICS. This one out of three android devices I own gets best reception wifi wise. Also, dont want to sound rude but should really search for a fourm thread that has been already been made about ICS bugs/issues. Please post here: http://forum.xda-developers.com/showthread.php?t=1780142 I'm just letting you know what a MOD or DEV would tell you here. Making new threads seem to clutter up the forum and people dont see the more in important threads that get bumped daily. For instance, I have almost 650 posts and I've only started one maybe two threads cuz everything can almost be found using search option. Sorry to hear you have bad data reception but I am sure you can somehow tweak/mod/make it better by searching all over the place. Good luck!

Bars mean nothing, they're just graphical representations. Settings -> About Phone -> Status will display a "Signal Strength" line. This will have a number, the lower the dBm, generally, the better. You could be getting the same reception, just the leak is handling the signal better or representing it differently graphically via the signal bars.

Much like Apple's "Death Grip" fix was..... they simply changed the graphical algarythm for the signal bar display a.k.a. - bar 4 had a larger signal window before it would drop to bar 3...
It's all in the numbers.
Does this happen to anybody else? When I'm on an ics rom my signal strength slowly degrades (i.e. i get less bars) until my network simply doesn't work anymore and I am unable to send/receive text messages or calls. 1-clicking back to stock then reflashing the rom fixes this. This has happened to me on AOKP, eriks miui and itzik2shs hebmiui. Why does this happen? Is there anyway to prevent it?

I noticed that my cell network signal strength doesn't seem as strong on ICS roms as well, or it'simply reporting it differently? Always seems lower than on GB. OFF TOPIC: I sorta want to try Barebone but I can't stand the stock galaxy lock screen. So for now I'm still on ICS.

It seems that bare bones still had the same signal for me after going back to stock. I went back to aokp ics and got around 0-2 bars. Then as soon as I calIed someone it went to a perfect 4 bars. Try calling someone?

Has anybody else experienced less than decent cell phone signal since upgrading to any CM10.1 derivatives? What's very strange, is that sometimes I'll have full bars, but still shows yellow on 'Mobile network signal' in the battery section (see screenshot). I haven't noticed any poor call quality, or too many periods when the data connection was actually lost.
I feel like this is impacting my battery life.. but maybe it's just a cosmetic issue?
I normally get great signal using the stock RUXLF3 radio.
- I've tried UCLK4, UXUMA7, UCLL3 ... each was no better.
I've seen this on a few ROMs also: AOKP, Sons of Android, and now I'm on PACman.
Any input would be appreciated.
I forgot to mention I'm on Rogers. I727R
It seems to actually only be LTE which is having issues.
I did some more testing today, and when LTE is disabled - the Battery screen shows green across the board!
Yes. I had same observation. I am back to 4.1
