Need help : Can scan cannot connect

Hey everyone,

I had a strange problem here.. After upgrading my laptop's memory, hard disc and refresh windows xp, I had problem connecting to my home wireless network.. When I used odyssey access client to scan for network, I can see my network with full signal strength. Then I keyed in my WEP keys and tried to connect... But instead of connecting to the wireless network, odyssey access client just keep trying to search my home network... I had tried to disable the WEP keys, but the problem still the same.. I tried with a few free wireless connection manager, but problem still persist. Anyone can help ? Thanks in advance..
