Bold 9000 WiFi not working after upgrade to OS5


I upgraded my blackberry from os4 to os5 and now my WiFi isn't working. When I try to connect, it says no networks found, then I try 2or3 more times and it finds my network, I click connect and it takes forever and nothing happens. How do i fix this? 

Everything was perfecrly fine before the upgrade. My brother android works just fine so it's not the wifi connection it's my blackberry. Please help

Re: Bold 9000 WiFi not working after upgrade to OS5



While there rarely is any formal documentation available, what I'd deduce is the specific version of OS5 that you installed may well have a bug in it regarding WiFi, and that is hopefully fixed by a later version of OS5. But first, let's rule out other possible causes.

I recommend that you attempt to boot into Safe Mode:

  • KB17877 How to start a BlackBerry smartphone in 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, try the WiFi again.


If it now works fine, then it may be one of your 3rd party apps that is causing the conflict...and you should look into those to see which could be causal.


If the behavior continues in Safe Mode, then indeed there may be a bug in the OS you have installed. You should consider other, more updated, OS packages, even those from other carriers. If you need instructions on how to install those (e.g., removal of the VENDOR.XML files), then do let us know.


Good luck!
