I've recently installed a Zyxel P-660HW modem/router onto my network, replacing a malfunctiong Linksys one.
Connected to this by a LAN cable is a desktop PC, while three laptops access it wirelessly. All are running Vista home.
After initial setup, all worked fairly well, with the main PC and the three laptops al able to access the internet.
The problem was that none of the laptops could see the main PC, and it could not see them. The main PC has the printer attached, so I need it to be visible on the network.
I've made some changes - making sure the network was 'private' rather than 'public' and ensuring all machines were on the same workgroup, etc.
After a bit of fiddling around with settings, I started to see the laptops on the network screen, and they could access the main PC.
But now the main PC cannot get onto the Internet!!
I've tried uninstalilng the device drivers, and reinstalling them, but that's not worked.
The main PC can only access the local network.
I've resorted to using a spare wireless USB adapter on the main PC, but I really want the reliability of the wired connection.
I suspect that resetting the main PC's network settings might work - so that it discovers the wired network 'from scratch', but other than resetting the router and uninstalling the LAN adapter drivers (both of which have failed to do anything), I don't know what else to do!
