WX2200 won't connect to APs AP3750 - 3COM

[Thad]

My WX2200 won't connect to any of it's 12 AP's. It was was fine up until I had a DHCP problem resulting in a bunch of duplicated addresses. All of that's gone away, now (for way longer than any DHCP lease time) but the APs still aren't working. They all show 3 Amber lights.

I can see on the DHCP server that all APs are getting addresses. If I telnet to the WX it can ping those addresses.

I have tried leaving the APs and WX powered off, overnight.

I have tried wiping the config on the WX and starting again.

I don't have the wireless manager software, just telnet and the web-console.

Can anyone suggest what to do? - looking in the manual, there's no suggestion of what 3 solid amber lights might mean. I presume it's just the AP waiting to get boot info from a WX.

Thanks in advance,

Thad
