I have two laptops at home both running Vista Business and until earlier today both were connecting to the wireless router/modem ok (a Netgear DG834G)but I decided to change the security settings to WAP encryption. When I did this the laptop I was using to make the changes via a cable stopped working wirelessly, after unplugging the cable, saying the settings on the computer did not match the router, or words to that effect. I therefore made some changes to the settings on the laptop and entered the password but it still wouldn't work.
I then went back to an open system but the same message appearred and a system restore doesn't seem to have put the settings back to where they were.
The other laptop is still working ok and I can connect this laptop via a cable but the wireless connection won't work. When windows tries to diagnose the problem I get the message that "wireless association failed because Windows did not receive any response from the wireless router or access point".
Any suggestions as to how I can sort out the problem will be gratefully received.
