[Q] wifi keeps switching on and off

Hey all,
since a couple of days I have a problem with my wifi, it keeps switching on and off (I can see the checkbox activating and deactivating, every couple of seconds, at the moment it is unchecked and says "error")
as I said, the wifi worked before
I am running cyanogen 7 (http://android.doshaska.net/cm7) on Milestone
- But I have also tried MIUI, with the same problem
does issue sound familiar to anyone?
Maybe it is an app which force turns my wifi on/off, is there any way to check which one it is (as far as I know I don't have an of them, eg juice defender, tasker installed)
Many thanks

Have you tried other WiFi networks? Because the same error being reproduced across two different ROMs seems a little unlikely.

Well, the problem is that my wifi doesn't stay on long enough (just a couple of seconds) to scan/connect to any network.

So it isn't a problem connecting to a network, it's a problem of the wifi not even being able to turn on?

Well "technically" it does turn on, but it switches off immediately

wow, i just logged in to search for this issue myself. I have that same issue across multiple roms also. The one that did work was the Telus Lite Eclair. I liked that one, but of course I wanted to check out others. Each one was the same as you describe. Wifi scans, disconnects, scans, in a loop.
I have done searches on google for wifi disconnect loop android, and seen some stuff about kernals and stuff that is over my head at the moment. If some one has an idea on how to get it working that would be great.
I wipe before any install, I've went back to stock and it works, everytime I went to the Telus Lite one it also always worked. I dont know if theres a clue there or not?
Im on an Telus milestone in Canada, on Telus network if that makes a difference.
And since I think this is my first real post, Thanks for the work guys.

Not sure if this would work, but this is the first result that popped up: http://www.droidforums.net/forum/koush/75782-wifi-disconnect-loop-cm6-final.html
EDIT: People are saying that Hidden SSIDs and MAC filtering can cause problems when trying to connect to the WiFi network. Try forgetting the network, making the network visible(protected if you wish) and reboot the phone and try again.

ok, time for a stupid question...
where do I find suitable kernels?
I can't find anything about this (roms and kernel tweaking is a is pretty well documented though)

As far as I know, you won't be able to change the kernel on the Milestone at all, due to the locked bootloader.

a little update, I checked my settings on my router and there was nothing really out of place. For poops and giggles I installed Shawdowmod, and it works with out issue with my wifi. Go figure. Anyway, think im keeping it.
Thanks for the help.

hmmm, good to hear you figured it out.
I just went back to stock and guess what? still nothing
maybe I'll try that rom and see

[Q] When I turn wifi off, Note does not connect to 3G or HSDPA

Hi guys,
I have this strange problem, it even seems random.
After I turn wifi off, my Note does not connect to 3g anymore.
And I have to reboot the phone to get it working again.
Does anyone experience the same problem, or knows a sollution?
I rooted KK1 and flashed LA4 using Mobile Odin.
Cheers,
Daan

I've had this problem once, but it worked again after a reboot. Haven't experienced it again. It happened on KK5, but i flashed LA4 yesterday, so it's too early to tell if it will happen again.
It also happened on my Desire HD with MIUI and also while running CM7, so it might turn out to be a bug in Android.

I guess you had turned/switched off data network mode by pressing and holding the turn off button for two seconds.
Try and turn it off and see if it is the same symptom that you had before.

No, this is not the issue.

I manually set the APN settings for Telfort, removing MMS and setting it up for "internet" only.
Did a wifi on/off cycle, with a short interval and it seems to work.
Going to test with a longer interval. Not completely convinced yet.
Hope it's fixed.
---------------
edit: Not fixed!
On wifi for half an hour, turned it off and [email protected]#$% 3g does not connect anymore.
Maybe it's just Telfort. They don't have the Note listed on their website, but still.

My infuse 4g does this. I have to put it in airplane mode then back to get my data to reconnect. It did this stock and on serindipity 7. I couldn't find a fix either.

Annoying stuff! Cycling airplane mode does not work for me, only a full reboot.
But if you had the problem too, It could be that it's the network's (in my case Telfort's) problem.
Maybe I have to get my sim replaced, but I'm switching to T-Mobile in about a month.
So it's a bit of a pain.

I am currently using the infuse on o2 in Germany, but it did it on att in the states also. I can't wait to get my note. I am just waiting for it to be released on o2 over here. They have the black but I really want a white one.

Telfort used to be O2, it has been using KPN's network for a while now.
So it's probably not connected. Though it is a strange coincidence.
I'm off today, I think I'll walk by the Telfort store to ask for a new sim or something.
Maybe they'll have to flip a switch somewhere.

Yeah you're right, I have to troubleshoot properly. But it's such a pain
And I think I recall having this problem a few roms back as well.
I'm not sure because I was on wifi all the time.
But I have to wipe, I'll use titanium backup so it won't be such a hard blow
Man I'm going to pissed if it turns out to be the network

Thats a pain i was so tired of formating,..reformatting....coz many custom firmware have some error and new updates keep coming almost daily...and all ask to wipe for best experience..dat was when i finally decided to come bk to stock and stick to it...
yeah it doesnt hav those fancy colors and throbbing speed which a custom rom boosts about but...but hey everythin works flawlessly and i dnt have any tension of random reboots and alarm not ringing..or any smartphone related error to comeup...plus all my apps and schedule is there forever no reinstalling tension....enjoying my phone....

Okay, so I I did a full wipe and installed a deodexed rooted LA4.
I still have this issue.
Also tested on KK1 stock and still experienced this issue.
If it does this on KK1 and LA4 it's reason enough for me to believe it's the network.
I'll just wait for my T-Mobile plan to start. Meh.
edit: It seems to work just fine on CM9 :-/

Losing 3G Mobile Network on certain location

Hi Experts out there,
I have been having 3G mobile network issue with CM7 base ROM. On certain location, I cannot download and make or receive calls. my 3G icon arrows show upload activities but no download happening. My ISP name (Maxis Malaysia) showing as normal. I upgraded to CM7.2, tried Kang ROM, preshoot kernel and change new SIM card but doesn't help.
Disable and Enable the 2G only a few times might resolve the problem for a while. The may come back again as long as I am still at the same locations.
Anyone has any ideas on this problem? ROM or Kernel issue? Recommendations on solutions? Thank you.

It's not the phone. It's signal coverage that you're having problem. Try another location and see if that helps.

I have been getting full bar signal strength on the icon. If connected (after a few tries of enable / dissable 2G only), the connection will be good for a while (some time quite ok for hour). The connection on 2G is 100% stable and reliable. If 3G is weak, it should automatically switch to 2G without issue right?
Thank you for the reply.

No. The problem could be with internet access of the specific UMTS base station that you're connecting to at that spot, and not with the connectivity between your phone and the tower. In any case, it's not your phone, it's the base station, and there's nothing you can do but complain to your cellular carrier.

I have checked with friends (iPhone, Android, BB,etc) surrounding me on the same location, no one is complaining the same problem. That lead me to confirm that its my N1. The worst part is I cannot make or receive calls. I have been missing many important calls...

When did you have this problem? After or before you updated to the latest version of CM7.2? If after then I suggest you do a full wipe and format system and then reflash the ROM. Or you could try to flash a standalone kernel and see if that helps.

Another option would be to flash a different radio. Try to read the radio section on Nexus One thread for more information

I just flash MIUI ROM and will put it to test tomorrow. Hopefully it will be fine. If not, will try to flash different radio. Thank you for all the replies.

Here's a couple solutions:
1) Go to settings>wireless>mobile networks >access point names. Look and see if an option called "Simple" is ticked. If it is, tick your network name instead of Simple. For example, for me, I have T-Mobile; so I have T-Mo ticked and not Simple.
2) Try flashing a new radio or ROM. I highly doubt this is your problem but it is worth a try. Try the .08 version radio or the .12, whichever you don't have.
3) Go to your carrier's store and see if you can get a replacement SIM card. I did this once and they gave me one for free. Just say you are having connection problems and you think your SIM is cutting out. My N1 once fried a SIM card. Just re-read post and seen that you did this. I would highly suggest you try my first option as I had a very similar problem and solved it that way.

SORRY IM HAPPY CAUSE THIS DOES WORK EVERYTIME DANG T-MOBILE GET AT&T TOWERS btw HAPPY EASTER EVERYONE leave me a egg

I have tried MIUI ROM and latest Radio (5.12) for passed few days. The problem still remain.
The new radio giving more stable 3G connection many locations but lost 3G connection on the previous problematic locations.
Really not sure what to do with it now. I have tried everything that is known on the web.

There's nothing you can do. It's between your phone and local base station.
You didn't listen to me earlier, I guess now you will.

It is sad that nothing can be done. The phone should at least switch to 2G when 3G is not available, but my N1 stuck there causing me loosing voice and SMS capabilities. This is fundamentally wrong on the phone.

Wi-fi always on?

hi, i'm new here and didn't found nothing to fix my problem.
I'm trying to use my wifi always on, i already set the wifi-policy on always but it still disconnects when my screen turns off so i'cant get notifications like mail, whatsapp, steam, etc.
i already tried with the different "wi-fi lockers" in the market but nothing.
my previous phone (galaxy 5) didn't have this problem so i think the router it's not the problem.
also, i'm using this baseband "S5830CVJKL4" and obviously in a 5830m (same as c and i)
thanks.

Is your mobile data/roaming turned on ?
Sent from my GT-S5830i using xda app-developers app

Are you using a battery saver (juice defender, for example)? If so, make sure you don't let it control your wifi.

i'm not using battery savers and my mobile data is turned off.
i'll try with a different baseband today, not sure if that have something to do with the wifi.

Weird, i use advanced wifi locker for another tablet that i got that problem and fixes it, though, i noticed that works in some roms and in others don't.
Anyways maybe is because the rom? i use the stock galaxy one and i don't need to use 3rd party to get the wifi on always.

well, aparently IT IS my router, tested in a friend's home with his wifi and didn't have this problem.
weird, the problem it's only when my screen is off, i guess i'll call my internet provider tomorrow, thanks guys.

[Q] Unable to activate mobile data

Hi community,
I'm a long-time lurker but just until today had the need to join this great place and bother you with a question. I already used the search feature and even googled this problem, which didn't quite helped as I'm still clueless.
Last nite, I switched ROM on my Desire C after being a long time user of Revolution MOD (thanks to @russell664) because sudden reboots started to affect my pone almost daily.
So I went ahead and flashed MiniJBProject (thanks to @penguin449) following the right steps (clean flash), rebooting after install in order to get WiFi enabled and everything seemed to work well until this morning, when I went outside my house and noticed Mobile Data doesn't work. I tried re-flashing ROM, switching between NOPE (thanks to @me4488) and Prometheus (thanks to @nikhil16242) kernels and frequencies to no avail (my pone doesn't go beyond 750 MHz), cleared Dalvik cache, fixed permissions in CWM, nothing.
As I said, WiFi does work just fine but Mobile Data is just not sending/receiving, I'm able to move the slider ON/OFF but get same results.
Then I thought my pone didn't like this specific ROM so I then flashed Revolution JB (thanks to @addictz10) again through clean flash, rebooted to get WiFi, and so on. Nothing. Still the same.
I feel like probably the problem has to do with CM10, since I didn't experience this issues with any of the Revolution Series ROMS.
Any further info you might need to shed some light, please feel free to ask. I'd really appreciate any input.
Thanks in advance.
By the way, I currently have Revolution JB in my pone.

I think you have to enter the apn settings for your carrier. Google for it. Go to settings, wireless and networks, mobile data, access point names, and enter your APN settings.

Most Roms will be able to use mobile data straight off the shelf if using a known, big carrier, for example T-Mobile, however if your using something more local, something not as well none, then you need to add the APN, if your on contract or PAYG with a different company that provides your network service, like TALKTALK uses vodafones, you need to add it otherwise it connects to vodafone, and uses vodafones APNs which, will not work.

Gotcha. Now I know for future ROMS. Thank you @penguin449 :thumbup:
