How to configure Hardware Linksys??

[mokore]

I have the above router which is connected to my two main PCs via ethernet cables. It is then connected to my PS3 using the wireless feature.

The problem is whenever I turn on/off or reset my PS3 the netowrk goes down and I have to wait 30 seconds or so for it to be recognized again and for the network to come back up.

Someone suggested trying to update my firmware. Thought I would ask here first before attempting anything.
