toothache

Ok, i managed to locate the belkin page (using direct cable) and updated the firmware as instructed. I also restarted the router while i was there but wireless still doesn't work. There is a 'restore factory default' on the page too but am unsure of doing this. I have the network password encrypted but will restoring alter this? I don't want to mess up the second laptop connection which is working perfectly. Thought i'd better check before i did anything.

Thanks.
