I hope someone can help me. This happens to me every time i flash a rom based in cm10.
When i connect to wifi, everything seems to work fine. The wifi icon is blue and webpages loads just fine. But after 1 minute or less, data transfers stops. I can't load any page, play store doesn't work either, but the wifi is still connected and blue.
Right now i'm using paranoid rom (i tried several others roms from team-optima, but the only one without any problems are the stock based roms). And my phone is an e612g, and i'm from Chile.
PD. In google i find some solution by disabling automatic date and time zone, but it didn't work for me. I tried too, changing the region code in wifi advance options, but there is no Chile, and non of them worked for me neither.
PD2. After ten minutes of internet inactivity, the wifi icon goes grey.

Hi, I have used many ROMs to find out what is best but after some use of most ROMs (all froyo), I have noticed that no matter what I do, mobile internet won't turn on. It usually happens after the second reboot and various methods of toggling the mobile internet fail toturn it on, even when they say that the internet is connected.
The problem is that I have decided that my favourite MOD is a 2.2 (froydvillain) and the fact that I have no internet is not helping.
Basically, can someone help or is it a Hardware fault?
-- will updating my Radio help?
Hmmm, strange. I have no idea why it works first but then stops after a few reboots, I'm using FroydVillain and internet is 100% ok.
Yeah it is always recommended to have the latest radio,... give it a try, cant hurt can it, and you can always roll back to an older one if the update causes issues.

After flashing CM6.1 I got the notorious wifi connectivity issue that numerous people have been reporting around the web. The issue is the following:
1: Wifi discovers neighbor's AP but no longer home AP.
2: Wifi problem randomly fixes itself, but sometime comes back and home AP can't be found again.
Many random solutions on the web include removing all stored AP's on the phone, resetting the router, rebooting and power cycling the phone numerous times, etc. Most people report that wifi miraculously start working again after the above but there is no consistency to exactly why and what works.
I tried all of the above with no luck, and even flashed three different roms with different kernels, did wipes, formatted everything inculding boot partition etc.
Here is the ACTUAL problem:
Different regions use different wifi channels. North America uses the first 11, most of the world uses 13, and Japan uses all 14. After flashing CM6.1 it changed the regulatory domain on the phone to only scan the first 11 channels meaning my European router broadcasting on 13 wouldn't show up. This setting seems to be persistent and doesn't change just because a new rom is flashed.
The reason people report the problem to be randomly fixed after a few days (and sometimes coming back days later) is because most routers automatically select which channel to broadcast on and therefore might end up within the first 11 at occasion. If it changes to something higher after that however, the problem is back.
Solution:
Open Settings, Wireless & network settings, Wi-Fi settings. Press "Menu" and select Advanced. Press regulatory domain and change to 14 channels.
To learn more about this and understand which channels are used in which countries, look here: http://en.wikipedia.org/wiki/List_of_WLAN_channels#2.4.C2.A0GHz_.28802.11b.2Fg.2Fn.29
Thanks man, even I still met an issue which was wifi disconnect frequently (usually after 12 seconds or less, it's re-scanning AP and trying to re-connect again) when I was trying to share my broadband internet from laptop to my legend.
BUT, after I update my wlan driver (now using 8.0.0.238 for my Atheros AR5XXX), the issue seems gone.
I found that by updating wlan driver to the very latest driver (for mine is 9.2.0.xxx) is not a guarantee to resolve this problem.
Now, by combining your suggestion and an "appropriate" driver version for my wlan, it work flawlessly until now
PS: driver version which will work varies from devices to devices. Do trial and error if you must
edit: well, not 100% gone, but much better . the connection is far more stable
Could be a problem for some but not all the issues with WiFi. I knew about this and even posted one or two times this check for the number of channels in different other topics as a possible solution. Still there are times when the connection to the "home" AP is done very late after entering in range or switching on the WiFi and the signal is changing from none to full and back frequently, for the same relative position to the router (I'm standing in the same place). Also even if the signal is full or good, the Legend seems not to have Internet connection that is, the weather updates or XDA applications or browser could not connect. This is still happening even if the selection for the number of channels is correct. And also this is not happening with a stock ROM, I made some comparisons between my Legend and one of my friends that has stock ROM. He is having full signal and excellent browsing experience while I have random disconnects or drops in signal level. My thought is that the difference between drivers made by HTC and the ones in CM ROM is the cause. As it is with some other HTC proprietary developments (like Flash implementation or FM radio), could be that HTC spent some more development time in eliminating bugs and making a better driver.
Of course, this will not stop me use CM ROMS, it is a little bit frustrating, but the other things in CM ROM's makes the difference for me.

I think you're right. Yesterday, I tried my friend's phone (which has a stock ROM), using the same AP and there was no dropped signal or disconnected in wifi. I also tried using other android phone brand (5 series from samsung) which also has a stock ROM and there was no problem at all. Drivers is the culprit
Work
Thanks u very much.worked on my milestone
Thanks. Actually worked.

Hello Rapier,
I have installed the CyanogenMod 6.1.1 (stable) on my HTC Desire (GSM / France) with latest radio image (32.49.00.32U_5.11.05.27) and taken some time to configure it. Now, everything seems to run well ... excepted the WiFi (and perhaps also the GSM). My problem is exactlw what you have described:
- on stock ROMs, the WiFi signal is stable and quite strong
- on Cyanogen ROM 6.1.1, the WiFi signal fluctuates, the connection is unstable and gets lost.
I like CyanogenMod ROMs very much. The WiFi issue is the only thing that I was not able to correct. You were speaking about WiFi drivers: would it be possible to extract the WiFi drivers from the latest HTC Desire stock ROM and copy them into the CyanogenMod installation?
My impression is that the CyanogenROM is scanning for networks in the background, even if a stable and strong WiFi network has been found and is currently connected. Perhaps there is a possibility to disable this scanning?
To finish, I have also the impression (I know, this is not very scientific ... but perhaps it could help to determinate where the issue comes from) that the GSM network is also fluctuating. I use WiFi Analyzer (available on the Android market) and when I plot a graph, without moving the phone or even without moving myself, the plot oscillates between -80dBm and -30dBm (I swear that there is nobody playing with the on/off button of my ZyXEL router ).
@sz1a: Thank you very much for your post: this helped me to discover these "hidden" settings, but my configuration is manual on the ZyXEL and everything was fine. Perhaps you should switch the thread to "unsolved".
I'n not a developer, only an ethusiast with a Legend. Also I'm not a Linux expert so I can only guess and experiment...threfore I cannot tell if porting HTC proprietary drivers is possible. I'd say not...if it was, we would have it by now. The main reason I think, is that those drivers are not open source, so nobody can port them since the sources are not available. I'm sure that if it was possible, they'll have been included in CM

pleaaaase help, im running CM 6.1 RC 1
wifi was working fine untill yesterday, i tried to connect to my friends router but couldnt.. i tried putting it in manually too.. then i couldnt connect to any router infact my phone wont even pick up any even my home one.. i tried switching to 14 channs like this said but no luck
any help please
I flashed my TMO HD2 to the below ROM for about a month.
imilka's Gingerbread Sense v05 [Des HD][Sense 2.1][K:raf1.9OC]
The internet / data connectivity was working fine since I flashed it. However, it started to have a problem several days ago. Although my phone showed the icon for HSPA with good signal, it failed to connect to internet 10 minutes after in use. I stopped and restarted Mobile Networks, it would work for another 10 minutes and down again. I also tried to reboot the phone, but the same issue recurred.
Any suggestion that can remedy the issues? Thanks.
try a different rom and see if it does it then
Hello. I have been using void until now. Sometime ago I tested Oxygen. I immedietly noticed a problem with connections. The phone had to be in roaming mode to get any connections at all. Even then I was only able to call and send txt but no internet was available.
So I switched back to void which worked like a charm.
Today I suddenly got the urge to try something new again. So I installed MIUI. The same problem exist with it as it did with oxygen. No internet connection what so ever. After furiously messing with the roaming mode button and a couple of restart the internet connection suddenly came to life. But it is extremely slow and it suddenly disconnects from time to time.
I have a model bought from finland and it was originally with saunalahti version of 135. Any help on how to continue using 2.3 based roms would surely be appriciated.
This is not rom problem. I used all roms and never ever had ANY of problems. ANY.

Let me clarify this once and for all. Android is a slightly different OS, it uses something called middleware, which acts like a bridge between the hardware and the drivers on each Rom.
Now going back to your B135, which is very old btw, you need to upgrade the Stock Rom to at least B137, which will upgrade your AMSS file. This way the Wifi/3G/screen/sensors modules get updated firmware and that should fix your connectivity problems with 2.3 drivers.
Saunalahti is MVNO and it roams on Elisas network so it's normal that you need to enable roaming. Stock ROM has modified RILs or something so that they recognise Elisas network as Saunalahtis and then you don't need to enable roaming. I tried getting those RIL work with Oxygen but those didn't fix it. Cyanogenmod has settings so you don't need to roam. (atleast you can get rid of that roaming symbol)
I don't understand why it works with Void and FLB, maybe those are based on some other MVNO's stock rom idk. Or does it work as it should on every Froyo ROM? Haven't tried other ones and really cba.
You can just enable roaming, you won't get any fees for that as long as you roam on finnish networks. (and it just roams on Elisa afaik)

This is a well know problem. As you know, Saunalahti runs on Elisa's network and when using 2.3 roms, operator is identified as Elisa, thus making the phone think that its roaming.
Some have tried fixin this, but nothing yet.
There is no harm enabling data roaming (international data roaming can be disabled from oma.saunalahti). Or by using CM7 which has an option for "national data roaming". That also removes the roaming icon...
sorry a lil OOT,
how about other features like usb tethering on 2.3.x?i see all gingerbread roms for huawei ideos x5 have issue on these.
is there any solution/workaround for usb tethering?
thanks
About a month ago I noticed that my wi-fi is working weird. It is connected, but I can't use the Internet. Looking at the wi-fi icon I can see that it is sending data to my router, but it is not recieving anything back. I basically have the arrow going up, indicating upload, but no arrow down, indicating download. After a few minutes (or after restarting wi-fi) it goes to normal for some time and then it stops working again. I'm currently on optimised CM12.1, but it doesn't matter which ROM I use. My router works fine. I checked with another phone while my s4's wi-fi wasn't working. I was considering updating baseband and modem, but I wasn't sure which one to use. I'm in Poland and my carrier is Mobile Viking, but they use Play infrastructure (or T-Mobile, if play is unavailable). It isn't anything that would make me change my phone, but it is a bit annoing.

It's like you said. The only thing you can try is changing your modem.
Do you have a stable connection on other wifi networks?
I have no way of checking other networks (living in a small town with no public wi-fi). Which modem should I use? I'm in Poland nad I bought my S4 in a store (not from any carrier)

There is no best modem. You have to try it for yourself. I would suggest taking lollipop modems, but you have to be on a lollipop bootloader for that.
If I am on lollipop rom, does that mean that I have lollipop bootlader? When I bought my phone it was on android 4.4.2
Since lollipop my wifi has been terrible on my i9505 stock rooted. My iOS and windows devices are rock solid but sgs4 has crap connection strength. On previous devices the radio with the upgrade was normally to blame but I'd welcome any suggestions. Does cm12 use the same radio as stock?
