[paulC1986 0]

Hi guys, recently    i  accidentally shut down my pc an since rebooting i have been unable to connect to my wireless network. I  have been using  it sucessfully for about a month.until today.  It finds the network fine, but when i attempt to connect i get the following error:

Wireless Association Failed because windows did not recieve any response  from the wireless router or acces point.

Im running Vista home premium 32 bit and using a Zyxel G-202 wireless usb  adapter to connect to the router, however my laptop running Xp has no issues connecting at all

any further info anyone can elp requires il be happy to provide:)

*edited spelling

I would reset the router to defaults, and reboot both the windows machine and router.  Who knows what went wrong.
