We have an office with some 50 XP machines on our SBS 2003 network. About 25 of them connect wirelessly, for some reason we are having a problem where (randomly) half the machines are being issued with the wrong IP address - ie our address range is 192.168.16.XX but the client machines are being issued with 192.168.0.XX. Its driving me crazy, I have tried 3 different wireless routers but the problem is still there, if i log on to the router admin page it will show say 10 clients attached with half on the right address range and half not.
Also a client machine might be fine in the morning but then later on it's IP address will decide to change itself. If I then run ipconfig /all it shows that the DHCP server address is 192.168.0.1 rather than 192.168.16.2. (why God? why?)
The machines are connecting to the right routers, the signal strength is always excellent...but half the machines are getting the wrong IP address. I'm completely stumped at this point, any ideas are most welcome at this point.
(Routers used Netgear DG834G, 2 x Aironet 1100)
