I changed my RAM, now my Lion MBP won't connect to Wi-Fi

[Adamantoise]

Earlier today I opened up my 2011 MBP (Lion), changed out the stock RAM for 2x4GB DDR3 RAM sticks (Same specs as stock PC-10600 1333MHz)

I booted up my MBP and everything was fine, except the password to my network isn't being accepted. It sees all the networks in the vicinity but isn't accepting my password.

I have rebooted and I have checked the "Show Password" box to ensure it isn't a typing error.

Other computers are working fine.

I doubt these 2 events are correlated in any way, but just felt I should mention.

try to also reset your router. I recently had a router at my friends house not accept a password that I knew for a fact was correct. After unplugging the router and plugging it back in everything was back to normal
