|Old network, new router, new network setup.|
Installed new Netgear router. 3 laptops (XP, Vista, Win 7) could see each other, exchange files, etc.
Left house for several hours. Nothing changed except time. Now nodes can't see each other. Can't even ping each other. Each node can ping router and can get to internet with browser. Router is showing all nodes (3 wireless laptops, 1 wired printer) are attached.
There must be a configuration setting that is incorrect. Can anyone help with this very old question and new participants?
