I have a very slow laptop running XP pro and the wifi has stopped working - just get 'aquiring network address'. System is completely clean, no viruses, spyware etc. Thinking that it might be teh wireless hardware I installed a Netgear usb adaptor - exactly the same problem.
Disable or Uninstall the Netgear Adapter in Device Manager - Restart your computer - Run set-up again using your supplied Netgear CD - then plug in your Netgear USB Adapter - maybe this will do the trick.
I have a bthomehub2. My desktop works on wireless fine but my new netbook shows the wireless is connected but cannot get any web pages. I have tried all channels on the hub,restored to previous time,updated drivers.
IE8 gives me a message that it is the firwalls on PORT 80,Port 443 etc.
I am tearing my hair out as this happened on my previous laptop and I assumed it was because the card was old so binned laptop.
Contacted BT but could only offer channel change and no response to my 'does not work reply'.
