Recently I've installed 4 3COM wireless 7760 devices at a client.
Ever since, we had a lot of problems with the network, a lot of popups and notification in the eventviewer of an IP-address conflict.
I noticed that on all the clients the device that triggered the IP conflict had the same MAC-address.
After some searching I found out it was one of the 3COM devices who had that MAC-address. After unplugging that one, an hour later or so it started all over but with another MAC-address, the address of one of the other 3COM devices.
Now I unplugged all four of them and have no more problems, and no more wireless network :)
Anyone an idea on what can cause this?
Thx in advance.
