I have two 3com 11g access points connected to the same subnet, at different ends of the office,  Both are acting unreliably, one is called FVcustard (SSID) and the other is called FVcustard2 both are using WPA-PSK and both are using channel 8... (Is that a problem?)

The idea being the provide wireless access to the entire office.  
Our office is surrounded by several others and there are several other wireless connections available.  
DHCP is provided by or buildings ISP.

The main symptom is that devices can connect and authenticate but sometimes, it takes a very long time to receive an ipaddress, or they never receive an ipaddress or worse they receive a random ip address which is not from our subnet???

HELP!  It makes no sence .. other times it is completely fine and works perfectly. even transitions from one access point to the other.

They shouldn't be on the same channel.  Change one of them so that it is at least 1 channel in between - ie 10 or 6.

1. Random ip adress is a result of net receiving dhcp address, in that case windows generates address automaticly.

2. Both accesspoints *should* work on different channels, and the gap betwen them should be at least 3 chanels (ie: 1-3-5-8-11)

3. Not receving dhcp adress may be (and propably is) a result of lost packets.

First of all try changing chanel of one of the access point to ie 11 or 5 and try then.

Hope this helps
Regards

The more channels between them, the more bandwidth either can provide.

With both on the same channel, clients may have trouble talking to just one.  They may be giving up and connecting instead to some neighbor's access point, and getting an address from there....
