More information plese. What rom, kernel, modem? So you turned both off, and when you lock your phone, both turns on automatically? Do you have installed some app which manages connections, eg juice defender?

i am using the stock rom with cf-root. After i close both wifi and Data button in the notification bar,i lock my phone. When i turn it on again, both bitton have turned.on. i have never use apps like juicedefender.

Auto-switch between wifi and 3g

Does your connection auto-switch between wifi and 3g?
I was out earlier and the wifi was still locked onto to my home network yet I was no where near home. I wasn't able to browse etc as there was obviously no connectivity. I would have expected it to switch over to 3g or H.

Anything I might be doing wrong? Or settings that may need tweaking?

Could it be down to the fact that I have gps turned off so phone cannot track position? Do you leave this on permanently and if so what's the battery drain like with it on?
Let's get some response on this please. I would like to determine if I have a faulty device and whether I need to start arranging a return.
Thanks
I have GPS on, but it doesn't use any battery unless an app tries to use it. But I don't think this has anything to do with your issue. There aren't any settings that I've changed. Try a reboot.

Y5 Saver
There's a very good app called Y5 Saver - https://market.android.com/details?id=pl.polidea.y5 which autoturns your wifi on/off depending whether your in the proximity of the wifi router (uses network triangulation).
Only issue is that it seems to override 'airplane mode'.

No packet data after wifi off

When my phone is in wifi mode and then switching it off, packet data doesn't appear in the status bar or turn on. Rebooting didn't help, it's random luck and enabling/disabling packet data that only helps. Suggestions?

Backup and factory reset.

Which stock or custom ROM you are on. This basically is a combination of your service provider and the gingerbread version (if) on your phone.
Thanks,

Phone freezing when toggling mobile data

Whenever I toggle mobile data on/off the phone freezes but the power button will still toggle the screen on and off but the device will not respond until it eventually reboots. This happens when I turn wifi off, but not on, or when airplane mode is toggled. I have tried from settings and the status bar.
I'm running Stock, rooted, deodexed from here http://forum.xda-developers.com/showthread.php?t=2044351 along with the APN editor flash (method 1) http://forum.xda-developers.com/showthread.php?t=2044449 with Setup Wizard frozen. I also have extsd2internalsd http://forum.xda-developers.com/showthread.php?t=2036796 installed to utilize my 64gb sd card.
I tried to get a logcat using adb logcat *:W *:S but it was empty.
Anybody know what's going on before I wipe and try again?
Thanks
As weird as this sounds it appears to have been FB Messenger. Clean installs worked so I reinstalled one by one and this was the only app to cause the device to hot boot when toggling wifi or mobile data.

Nevermind, FB Messenger wasn't the culprit.
It turns out it was the AT&T VM Viewer app (for U-Verse VM). No problems if it's just installed but if you are logged in then whenever the apps loses connectivity (toggling wifi, mobile data, airplane mode, etc) the phone hot boots. This just reminded me the app would FC on my old Incredible 2 when the connection state changed.

why cant I download any roms when my screen "mutes"

My screen times out after one minute of inactivity. So everytime I go to download a rom any rom (MIUI/ CM/ PA/ etc) the download stops. How can I change this OTHER then leaving my screen on
What Rom are you using now? Does it let you control the WiFi sleep policy? In most cm types you can goto WiFi then advanced and make sure WiFi is set to always on when the phone sleeps.

Im using CM 4.1.2. rom since 4.2.2 wont sync any of my contacts/gmail account or apps. I have the wifi sleep policy to never
It may be different on your device but I am pretty sure the menu says Keep WiFi on during sleep?? It should be set to always if you don't want the WiFi to be turned off once the phone sleeps....
