Has come up against very strange situation.
There is small office network to 10 personal computers (systems different from Win2000 to Vista). One file server (system Win2003 R2 SP2) with static IP the address and the network printer, too with static IP the address. All this PC receives ip addresses dynamically on wi-fi from router Cisco-Linksys WRVS 4400 N, except 2 static devices - the server and the network printer.
Problem essence - I need connection of the new laptop and new desktop (on both it is established Win Vista Home Edition), on wi-fi communication - is. On wire connection(LAN) - dynamic IP at all doesn't receive, if I register - statically shows any exchange of packages, but other personal computers in a network - not pinging. Under wi-fi, on the laptop and desktop(via USB wi-fi adapter), all perfectly works.
Tried to disconnect firewall and DHCP on a router. Connections on router ports too changed. Patchcords checked a cable-tester. Rebooted a router - any effect. Who can faced - prompt.
