Trying to share my internet connection with my folks who are installed in the granny flat.
I do this via a wireless ad-hoc (peer-peer) network using NAT & IP forwarding via the wireless NIC.
I seem to be able to get it up and running but it seems that when my Dad shuts down his windoze machine and then restarts it later, for some reason I have to restart my wireless NIC (ifdown wlan0; ifup wlan0).
I think the same thing happens if there is some connection interruption for a period of time as well, which happens occasionally because we're pushing the wireless distance a bit, I think.
Any suggestions why if I have to "restart" the wireless interface?
