Vista wireless internet connection

I have Toshiba laptop <1yr old running Vista. Wireless internet via hardware
provided by comcast has functioned fine until 2 days ago when it stopped
connecting to internet. Laptop recognizes the wireless network i created but
says "limited connectivity" or something like that and won't get online.
Comcast helped me set up wireless network with WEP encryption. Not sure what
changed in last two days. Desktop pc running XP hooked up to same router
accesses internet no problem. Any help greatly appreciated.

Any new Microsoft update installed recently?

I did not do any Windows Updates recently. However, somehow, I seem to have
resolved the problem. I first went to connectivity doctor to see if it could
diagnose the problem. Then I went to the settings for the wireless connection
and changed the security type from "no authentication (open)" to WPA personal
and the encryption type from WEP to AES then entered in my network security
key. Windows checked to see if that fixed it and it had not. So I went back
to the settings and reverted them back to their original state. Windows
surprisingly came back and said that fixed the problem and I was able to get
right online. Any clue what happened?

I think that this experience just underlies the apparent weaknesses in
Microsoft's implementation of wireless networking support in Vista.

Thank you for the feedback. I think "from WEP to AES" makes different.
