3G Connection Problem after ROM flashing

Hey!
each time I flashed a new rom, the setup of 3g internet doenst work anymore.
i entered all data like they should be, but it doenst work.
after a while, sometimes hours, sometimes a day or longer the connect works again without doing anything.
I dont understand why!
anyone got a tip for me?

Ok, lets get more information...
the interessting thing is, that if i do a full backup of my system when mobile internet works, and restore it after a flash (or hard reset), interworks works immediately.
when not, no internet for uncertain times

Are you sure connection setup runs on startup. I mean you're internet settings must be setuped before it works and this starts automaticely some time after you connect to your phone network.

some time ago i tried it aner it didnt work.
now i tried again and now it works =)
Still I am very curious why I cannot change the settings manually...

Extreamly weird WIFI problem

Hello friends,
I have a very strange problem:
My WIFI suddenly stopped working. When I try to set it on in the comunictations section in the settings tab, it shows like it tryes to set it on but it stays off. even when i try to do it through the old winmo interface it cant set it on.
I tryed soft reset and even hard reset it twice.
nothing works.
any ideas?

if it try to connect and fail
the only way to get it working again is to pull the plug from the wifi
router for 10sec and reinsert it
same way with mine and on all handheld devices
my laptops don't seem affected
and if I set the ip gateway and dns manually the handheld can connect fine
so the issue must be with the dhcp in the router

It doesnet works
you dont understnad.
my WIFI device or driver just wont start.
i cant get it to ask for IP so it has nothing to do with DHCP.
it happens everywhere and every net
please help
i tryed to hard reset it again and it didnt help

anyone????
HELP!!!!

Have been talked about earlier.
Had the same problem with my first Diamond and it was replaced cause it was 3 days old.

I have mine for 8 month i think. maybe less.
shall i replace it?
nothing i can do?

[Q] Phone will connect to open wifi network but not secure ones

Had my phone for a few months now and recently found that it can't connect to my secure network at home.
When I turn wifi on I get the dreaded connect/disconnect message while it constantly tries to connect to my network. If I leave it on then the battery will drain overnight while the phone tries to connect. I have an iphone which connects to the network no problem. As does my laptop etc
To try to fix this I deleted all my new apps, especially the push ones which give me news updates, etc but this has made no difference.
The weird thing is if I turn off my router's security then the phone will connect and works perfectly fine. I've tried using all the different security settings (even WPS) with new passwords etc and everything seems to setup fine on the phone except it just doesn't want to connect (or more accurately stays connected for a microsecond).
If I go back to an open network it connects immediately and stays connected.
I think this is the root cause of the wifi connection problems that many other people are getting. But I'm at a loss to try to understand why it won't pick up a secure network but works fine otherwise.
My phone is using 2.2.1 and has been rooted
Any thoughts?

Root the problem highly unlikely ..
Secure home network test .
Remove security from Router that is no password .
Remove that connection from phone .
Reboot phone let it pick up router and connect .
If it does then delete reset router password and add in phone .
jje

Thanks for suggested fix. I'll give it a go and let you know if it worked.
Root was a bad choice of word..... I meant that while looking for a solution to my wifi problem I noticed many other people complaining that they can't connect to a wifi network for one reason or another and I was thinking that maybe broken security is a common cause of many wifi connection issues.. In my case there was nothing physical at all to suggest that security was an issue, especially since all my other devices work fine on the same network.
Cheers

Hi, tried your suggestion but I still cant connect. The first time I rebooted the phone it knocked out my internet connection! I've setup a static IP address for my PC and the phone was insisting on trying to connect using the same address and creating a conflict. I fixed that so that's not the issue.
This is what I've tried..
I checked to make sure DHCP was enabled in the router, rebooted everything. No luck.
I tried adding an IP Address Reservation for the phone and assigning a dedicated static IP Address. No luck either
I tried connecting the device using WPS. It all went as it should - my router saw the device, added the mac address to the list of devices etc. The phone acknowledged the handshake. But again it still wont connect.
I checked the router log and it says "DHCP IP: (192.168.1.2)] to MAC address B4:07:F9:336:3D, Tuesday, May 24,2011 03:08:48" which I think is what it should say.
OK I've just fixed it!!! Or at least its connected.
All along I've been securing the network with WPA2-PSK. I just changed it to WEP and the phone connected immediately. I hadn't considered WEP because I read that its not that secure and I do all my banking etc through my PC.
I've tried all the other security options and only WEP works with the phone. I suspect its a compatibility problem between the phone and my router (a Netgear WNT834B v2) because both the phone and router work independently but not very well together. There's plenty of posts discussing the Galaxy S connecting to WPA networks so it can do it.
Now, after trying all the other security options. It won't connect again even on WEP. Bummer. It is acting slightly differently in that its trying to acquire an IP address instead of simply not connecting, although it doesn't seem to be able to find one.
I need to try this on a friends network and see if the router or the phone is to blame. I've no idea... but the phone's a bit too touchy for my liking

I had a similar issue, I had to reflash the ROM to get it to work. Backup all your contacts and stuff and then do a full factory resetting. See if that helps, if it doesnt, reflash the ROM. It should work.

Well I've spent the last few days looking into this issue and it's considerably more widespread than I first realised. The problem is that while many people have a wifi connection issue we all seem to have variations on a theme.
As I say in my case the phone will connect and stay connected to an open network but won't touch a secure one. I tried many suggested fixes and nothing's worked so I am now trying a factory reset.
A couple of questions: there appears to be two ways to do this, a factory data reset through the phone menu; and a hard reset using a combination of volume buttons, etc. The hard reset seems to be the deeper of the two.
When you say full factory setting which one did you mean? I am currently data resetting and therefore using the "authorised" Samsung reset
But how long does this process take? My phone has had a black screen and been vibrating every 10 seconds or so for the last hour. It's getting quite hot and there appears to be no end in sight. Has the phone hung or something? If it has how do I get out of this without bricking the phone? It's beginning to concern me because I'll have to do something real soon.
As an aside, in my search for a solution I found something that might help someone people (it didn't work for me). According to the bloke who posted it, the problem for everyone is that the wifi drivers have not been installed properly and if you enter *#*#526#*#* on your keypad it unlocks a service access that reinstalls the wifi driver. I tried it and the phone told me the software was installed successfully but no change.

Waited long enough so pulled the battery out and restarted the phone. I get the startup screen but after that the screen goes black and it vibrates again every ten secs and I can't get in.
Have to try the other reset.....
Things are going from bad to worse..

Have managed to start a full factory reset using the volume, power and home button but it's gone back into the black screen and vibrating every ten seconds.
I know Im going off topic here but Ive now reset the phone, wiped the cache, tried to apply the sd card update (aborted because it can't find the directory) and it always comes back to the black screen and vibrating every ten secs.
Am now trying to reflash the rom. Oden reports that the flash was successful but the phone wont reboot. I tried a couple of times - one with Re-Partion checked and the other unchecked but neither will reboot. What could be causing that? I somehow remember that my firmware was JPH but I could only get hold of JPK. Could that be the cause?

I seem to have solved all the issues at last. Thought it was going to be a bit over my head for a spell.
Once I discovered that the only way I was going to get into my phone was by flashing the rom the first problem I came across was I didn't know which firmware my phone was using previously, apart from the fact it was 2.2.1 and from Asia. I guessed wrongly and after "successfully" flashing the phone it wouldn't reboot. I then noticed that there were only three variations of the 2.2.1 firmware for my region. The second one I tried went a little further than the first but I got an error message about the SD card. The third one installed no problem.
So I instantly checked the wifi signal and the phone connected to the secured network. And stays connected - so far about an hour and a half.
It's amazing how the phone deteriorated the way it did. Hope it doesn't do it again.
Thanks for any help/suggestions

[Q] Hp TouchPad running Android - Wifi force close

I've tested this with a3.5, Xron and Miui and they all get this problem. Maybe installing certain apps trigger this to happen but wifi will eventually slow down when trying to connect to a signal and will be essentially non functional since the OS will basically freeze and then tell you to force close wifi and it requires a wipe and fresh install to fix.
Has anyone else run into this problem?

Check this and see if it helps you.

I don't think its the same issue. In those instances you can still try to change which wifi signal you want to connect to, I think it just loops from connecting and it would disconnect. I think this issue is common and dropped connections occur as well.
But I'm talking about a situation where if you even try to enter the wifi options it will force close.

Before I changed it, it would take forever to get it to release the connection. I just kept hitting "Wait" rather than "Force close" it would take several minutes but would eventually come up and allow me to Forget the network.
It sure sounds like the same, not saying it is, but very similar.

I experienced this problem for the first time yesterday in area where was about 20 WIFI networks. Never ever it happened in my house on A2. A3 A3.5 or XRON2.8
http://rootzwiki.com/topic/13779-now-i-believe-that-there-is-wifi-problem/

I have the same issue today, Wifi setting is forced to close, and cannot connect to any Wifi signals. I think it's a bug and it related to the time or date. Because I didn't do anything and it just happened.
No new apps install, no setting changed, and the device was keep on, so it just happens.
Hope someone can find out where the problem is...so sad this happen on New Year's eve....

i have this problem also, the solution i found was letting the touchpad go dead and than begin to connect wifi again.

Similar wifi comments here: rebooting [or maybe toggling/other disconnect] with wifi on/remembered would get it into a state where it was scanning and connecting over and over without really ever working. this was only happening once it was 'remembered'. Going through the wifi settings to forget in this state involved hitting 'wait' a few times and then i'd reboot and readd. 1st wifi connect is always solid for me.
I've found: market.android.com/details?id=com.brilliapps.wifiandmorefixer
Does the same thing except it is one click. I rebooted after the first go, but now no longer. i run this and then readd wifi - all set.

[Q] T-Mobile HTC One WiFi not working after update

Early last week I ran an OTA update that took my phone 4.3 and 3.24.531.3. After the update the WiFi was connecting to wireless networks but was not receiving an internet. I tried changing the phone name to "HTC One" like many others have done and that didn't fix the problem. So I unlocked, rooted, and flashed a custom ROM thinking that would fix it. I was still experiencing the same problem.
So last night I relocked and ran an RUU to take me back to completely stock so I could run the next OTA update to take me to 4.4.2 and 4.19.531.10. But since I was not able to access any WiFi I had to use internet pass-though connected to my laptop. Even after the 4.4.2 update, I'm experiencing the same WiFi problem, but now I can't turn WiFi on at all. I have not tried re-unlocking and rooting yet either.
Has anyone else experienced anything similar to this?

I thought it may have been router settings at first too since I was at work when it first started happening, but it does the same thing at home as well.
I'll try changing it to something else again. Thanks for your reply

Yes, I understand that. I've done it before. Last tine it was named "Android_xxx" with some numbers and a letter I think. I tried that when I was one 4.3 and it didn't solve anything
First I have to get the WiFi to even turn on at all now

Just unlocked, rooted, and flashed with ViperOne 5.0.0 and I'm still experiencing the same problems. What's weird is that after the first boot, when you are asked to connect to a wireless network, my home network shows up, so that tells me the WiFi is on when it boots, but when I tried to connect, it failed.
Then once I was finished with the initial setup, WiFi won't turn back on, even if I go into the settings and try to turn it on manually.
