I cannot see my home wireless network from my PC. However I can see it and connect from others?

Question

I can see other (neighbours) networks from my home PC but not my wireless network. I know the router is working because my work PC connects without problems. My home PC did work at some point but now not.
Could it be a firewall issue?

Answer 1

you might have a conflicting ip address
check its not the same. if it is you'll have to alter one of them. the network ip's the easiest if it is that.

Answer 2

Change channels on your router, it may be hidden behind your neighbor's. (check sitting next to the router)

The only other reason is a dead wireless part of your router..

Good luck!
