Problem connecting to a wireless Linksys router with security enabled?

Question

I've got a new laptop, a HP Pavillion 6000, which I just formatted to get rid of Vista and install XP. For some reason however, I'm unable to connect to my wireless router on this laptop. All other laptops in my household can connect fine.

I use both MAC Filtering and a WPA Shared key (AES). When I disable the key (leaving MAC filtering), the laptop can connect, as can all the others. When I re-enable it though, the laptop can't connect anymore, though the others connect fine. It is prompted for the network key, but even after entering it, the connection doesn't progress at all (ipconfig reports media disconnected).

The router is a Linksys WRT54GL with DD-WRT v23 SP2 (09/15/06) mini - build 3932 installed as a replacement firmware.

Any suggestions at all would be appreciated as to why this laptop is unable to connect to the router when the password is enabled.

Thanks a lot!

I originally posted this on the DD-WRT forum, and didn't get any answers, so thanks a lot for any help.

Service pack 2 and all Windows updates have already been installed on this laptop, that was one of the first things I did.

Answer 1

It probably is the DRIVER for the HP card. Have you checked HP's site for a current driver. If I am not mistaken these are BROADCOM cards so you might be able to get an updated broadcom driver which supports WPA better.

This is an on going issue with WPA. If the drivers don't match the cards don't work. Windows configuration by itself won't solve the issue! Check HP, and Broadcom or Prisim, I am not sure which card you have in that machine?

Not knowing exactly which Pavillion 6000 you have I don't know which link to send you to but the dv6000 CTO was shipped with XP and has wireless drivers for XP.

Answer 2

Sounds like it is the encryption setting in XP.
It seems to me that Microsoft had put put a patch for XP for WPA encryption. Make sure that you have Service Pack2 installed as well
