I have a small wireless home network comprising router (which is as a DHCP server), one laptop and one desktop. On initial setup, I had to set the IP address on the laptop manually as it did not seem to be able to run DHCP. Nonetheless it all worked fine until last week. Now the laptop cannot see the router or the desktop client when I ping them. However, the desktop client sees both the router and the laptop when I ping them from it!?
I have even set the router to have a fixed IP address, and the other two machines to addresses in the same range, thereby leaving DHCP out of it, but the result is exactly the same, i.e no replies when I ping from the laptop, but replies from router and laptop when pinged from the desktop.
I have run "netsh winsock reset" and "netsh int ip reset" but no change.
Your help really neede here.
