Idea centre B450 windows 8.1 upgrade now wifi drops all the time

Hello,

I recently did the upgrade to windows 8.1 and now my wifi drops to limited or no connectivity all the time. I tried to update the driver but it still drops.

 

Any ideas? I'm sick of disconnecting and re-connecting.

 

Thanks,

 

Tom

hi TomN,

 

Can you check under device Manager what WLAN you have on your computer.

Realtek Broadcom or Atheros    It should show under Devicemanager / Network adapters and should say like Wireless or wifi 80211.

hi

 

Download this one first but dont install it yet

http://download.lenovo.com/consumer/desktop/h1100369.exe

 

Now open Device Manager and rightclick uninstall on your Braoadcom wifi

        When presented with a promted to delete driver software, Place a check on that box.

Click on Action on top of Device Manager and click on Scan for hardware changes,

     Repeat the steps from the beginning  until you dont have a checkbox on the delete driver driver software box

 

Restart the computer and install the driver I asked you download Earlier.

Reconnect to your wifi and See if that one will work.

Let me know your findings!

Cheers!

I think it's worse now. It drops to limited in about 5 minuites. Should I try installing again?

 

Thanks,

 

Tom
