IP Conflicts - just started after 1 year

Sat Aug 26, 2006 12:36 pm

We have a small WiFi Hotspot running on an MT v2.9.6 router with two Linksys WRT54G APs connected via NICs to the MT.

One of the two Linksys AP's is in WDS with a third Linksys WRT54G 500m away to extend range.

None of the WRT's is running DHCP, they just pass out IP's from the MT DHCP range on the Hotspot.

All has run perfectly for around a year. We have around 100 users of whom rarely more than 10 are connected at the same time.

Suddenly we are getting several users a day reporting IP address conflicts.

Anyone any ideas?

Many thanks,
Martin

UK, France, Russia is what it says by your name. Anyhow perhaps an upgrade is worthwhile as I don't know how much support you will get on an older version?

Yes, it's your network design that doesnt prevent one users from taking other users address(es).
Move along. Nothing to see here.

or someone connected buggy unit or a device that proxy-arps.
Infact when i think about it, it could just as easily be the WRT54G units that do it. Upgraded firmware recently?
