Alright I am having two issues.



For some time I have run an open network, unsecured.  No bad things have happened.



Decided to try and change this when a new computer I have refuses to connect to the open network.  Setup WPA2-PSK with password and no change with the new computer.  Refuses connection.  



NOW the old laptop won't connect with a the password.  Nor with ANY security setting.



Anybody have any ideas to try and fix this?  I have been wanting to go to a secure setup for a while (network security is part of my job, just not a major part) and this has me stumped.

either delete the wireless profiles on the laptops for that network or change the ssid and resetup.

The old laptop, what OS is it running?  I believe (it's been a while––we're in the IT biz, but it's been a long time since we had to put a SP on a client machine, and new deployments are Windows 7) that XP needs SP3 to support WPA2.  If you're running Windoze Vista or 7 then that's not a problem.  You can also try turning down the encryption to standard WPA, but I don't recommend it, I'd update XP first.

XP SP 3 on the laptop.  The new machine is Vista (I built it with a board that has a wireless card).

how
old is the router? i had an identical situation last year and the
router was old and needed a firmware update to work with vista.

Is it an Atheros wireless adapter by any chance?  Try updating your drivers.  Yeah, I know it's nuts but many Atheros adapters choke on WPA because of a driver problem.

Thought I updated about 4 months back, will take a look at it.


Not Atheros, but HP.  I'll take a look at it.
