New HTC Aria disconnects instantly from home wireless no matter what

[Psycommu]

Title. Phone uses Android, router is Linksys E3000. Security type is WPA/WPA2 PSK.

Yes, I know I'm typing in the password correctly.

I'm stuck using the Router's guest account which doesn't let me get on Windows Live or any other IM with it.

I connect, it accepts the password, and at the bottom it says "Disconnected" with no reason given.
Help?

Update: For some reason I can sign into Skype, Facebook, My Email and virtually everything else, just not WLM, haven't tried YIM and AIM because I don't use them

[Psycommu]

Anyone?
I'm getting severely irritated with this...

Which version of Android is the phone running?

[Psycommu]

2.2.2 according to the phone.

[Psycommu]

Bump, this is still happening and I can't figure out why...

Try making the router use WEP?

[Psycommu]

WEP is less secure. I don't want to risk someone trying to bum off of our internet again just because of my phone.

No one will get in unless you live next to hackers

My phone used to do that. I'm running 2.2.2 too.

Delete the wireless network on the phone, restart the router, then restart the phone.
