Problem Connecting a Wireless router to a PS3

Hi

Can anyone help me with this problem?

I've got a NETGEAR 54 Mbps wireless ADSL modem Router DG834G v3

I've got my PC and laptop connected to it no problem at, it just the PS3 that won't connect.

Keep getting the following message:

a Connection to the access point could not be established.
Check the security settings for the wireless LAN.
(8013013E)

Took my PS3 to a mates and he connected it to his router no problem and did a system update on the PS3.

Tried it again when I got home but still got same message.

Any help would be much appreciated

 

Make sure you have all updates for the ps3. maybe your security settings don't match up with the ps3 capabilities prior to newer updates?
