Have you tried to toggle airplane mode on and off? That works on occasion, though ive had better luck toggling the mobile network off and on.

3G not working...

I am running Fresh 2.3.3 with baseband 2.42.01.04.27 and for some reason, my 3G is not working. I have tried getting the stock radio and updating my PRL (my PRL version right now is flipz_01). Nothing seems to working. Can anyone help me with this?
Thanks a lot for any suggestions

I noticed that to. When I have WiFi activated, 3G disappears. I don't know if it's a real estate issue, or it isn't working.

Well 3G turns off when WiFi is enabled, but that is not my problem, my 3G just doesn't work, I have to rely on WiFi..

after I rooted my phone, the 3g didn't work. actually i'm not even sure if my 3g had ever worked before that. it's stuck on 1x.

Put the phone in airplane mode and leave it there for a minute or so, then turn airplane mode back off. That refreshes your phone's data connection. Then also try updating Profile in the Settings->About phone->System updates menu -- that refreshes your signal and data profiles with Sprint towers.

Thanks, but it didn't work... this is getting frustrating! I've tried everything! At least they're sending me a refurb, hopefully I get a dust filter this time around, too (and a "with Google" sticker on the back!!!!)

(Q) Galaxy Tab Data Mode

I have a question. Im using Gingervread 2.3.3 . I find it irritating to restart my phone if i just turn off my WiFi to use my 3 G. Is there any other way for my 3g to turn on itself once i off wifi?

just on the 3g by hold the power button for a second , and choose Data network mode and active it , after you use your wifi it will off , and after you aren't useing wifi it will on by itself
I have done that. My data network have never been deactivated before. But sometimes when i off my WiFi, my 3g doesnt on. Need to restart my phone then it will on.

When you turn on wifi, 3g turns off! But gsm phone calls will still go through!
I knowm but for my case, i off wifi, 3g doesnt automatically connect. I need to restart my phone then it will.

3g or E not turning off when I turn on Wi-Fi

This problem started happening this evening for no reason.
Normally when I turn on Wi-Fi 3g turns off. But for some reason this evening when I turn it on the e or 3g is staying on even though I have full Wi-Fi signal( sitting next to it).
anyone any ideas how to fix this.

Maybe try wipe Cache and Dalvik-Cache...
Are you on a custom rom?
Did you try a reboot?
You sure net trough wifi was not off?

Activate wifi and go to http://www.hostip.info/ from the phone to see what network interface the phone uses, if it's the 3G one it's probably the phone having problem detecting internet through the wireless router for some reason, if it's the wifi something is messed up im afraid.
Not sure where in the rom it's defined to shut it off when wifi is detected.

[Q] Wifi tethering on ICS AOKP and CNA

I:ve tried both CNA and AOKP ports. everything seems fine but for wifi tethering it sucks. I mean when I turn portable hotspot on it says turning on wifi. it gets stuck on that but when I press back or home and go back it's checked. the thing is there's no status bar icon or notif saying that wifi tethering is active or what. my other phone can detect the hotspot. but can't really connect. one more thing wifi is ok I can see networks and connect to them normally. any ideas? is it a known issue? on cm9 its fine though
edit: tried barnacle wifi. I get an error sayinng cant establish ssid for wlan0

WiFi internet isn't stable

Do you experience every now and then that your phone is connected to Wi-Fi, but unable to connect to the internet? My temporary solution is disabling then enable WiFi again, then it works. This never happened on my s3 before.

That happened to me a few times the first day I had the phone. I wasn't sure if it was my router or what. But it never happened again. It could also be that I turned wifi calling off right after that so not sure if it was related or just a one time blip. If you have wifi calling on, turn it off and see if it happens again.
