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.

I believe you're referring to the WPA security protocol, not WAP

Did you configure your router to use WPA-PSK? If yes, what settings did you use on your laptop after making this change? Have you tried using "WPA-Personal" as the security type, followed by "TKIP" as the encryption type? That should allow you to enter your WPA password.

Thanks for the reply and sorry about the typo - I did mean WPA.

I have actually got the laptop to connect by re-entering the MAC address - the last letter had somehow been corrupted!

In trying to up the security I chose WPA-PSK and added the password to both the WPA-Personal and WPA2-Personal options which came up. Can you advise as to which of these is the one I should try to use?

You're very welcome, and I'm glad your problem has been fixed

WPA was introduced to address the security issues with WEP. As far as security is concerned, I'd go with WPA2 (assuming your router supports it), mainly because it's designed to be more secure than WPA with TKIP encryption. Besides, WPA2 is pretty much the standard on Wi-Fi devices manufactured since 2006, so you might as well switch

Thanks - I'll try again later when I get back home and try to make the network more secure!
