Connected to wifi but can't stay connected to internet

Question

I currently have a curve 9300, and my service provider is Telus Mobility. I am connected to wifi and up till about 3 days ago everything was working fine, now it shows I am connected, but I can only get on internet for about 5 mins, I have to shut off all my connections then reconnect them for it to work again. Any ideas as to the problem?

Answer 1

OK...then, with your WiFi radio OFF (e.g., solely running on your carrier data network), I suggest the following steps, in order, even if they seem redundant to what you have already tried (steps 1 and 2 each should result in a message coming to your BB...please wait for that before proceeding to the next step):
1) Register HRT

Please wait for one "registration" message to arrive to your Messages app
2) Resend Service Books

Please wait for "Activation" Messages, one per already configured email account, to arrive in your Messages. If you have no already configured email accounts, please wait 1 hour.
3) Batt Pull Reboot
Anytime random strange behavior or sluggishness creeps in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.
Hopefully that will get things going again for you!
If not, then I recommend that you attempt to boot into Safe Mode:

It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, does the behavior still present? If not, then think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.
If the behavior does still present in Safe Mode, then you may want to try this procedure to perhaps narrow down the precise causal item:
Load your OS "bare bones"...if anything is optional, do not install it.
If the behavior presents immediately, then try a different OS with step 1
If the behavior does not immediately present, then run for as long as it takes for you to be sure that the behavior will not present.
Add one thing -- no matter how tempting, just one.
If the behavior does not present immediately, then again run for long enough to be sure it will not have the same problem
Repeat steps 4 and 5 until all things are loaded or the behavior presents
When the behavior presents, you know the culprit...the last thing you loaded.
If the behavior does not re-present, then you know that either step 1 or 2 cured it.
If the behavior presents no matter what, then you likely have a hardware level issue for which no amount of OS or software can cure.
Good luck!
