The network server is Server 2008, 2 Nics (1 Disabled).
The ip of server is hard coded 192.168.1.2, with gateway of 192.168.1.1 (Router). And DNS at 192.168.1.2 (pointing to self)
Had regular gigabit router with no wireless builtin in place. Used an access Point. Wireless devices cannot get the gateway IP. Some hard wired PC's get limited connection at random intervals. Devices look and have been verified to be setup correctly.
Changed router to gigabit Netgear FVS318N wireless router, and same conditions, wireless clients do not get a gateway ip when connected but connect limited only. Some PC's do the same, limited connections, and if hard coded with the ip information, will work, but not permanently, they eventually get limited connection.
Phones do not pick up the gateway IP.
The router has been replaced, the switch has been replaced, Server is doing DNS and DHCP, and they are off in the wireless router.
We have 1 server, 5 pc's, 1 mfp printer. I have seen today all working, then my pc dropped the dns, connection said limited, 3 users on exchange showed disconnected, then came back shortly afterwards by themselves.
I have scanned for bugs on all, including server. Any ideas?
