3Com 3CRWER100-75 WDS mode

Hi,

I have 2 3Com 3CRWER100-75 and I would like to configure WDS.
Channel is on both the AP's the same.
MAC filtering is enabled and setup on both AP's
There is no DHCP server is running
Both AP's have static IP addresses.
WPA or WEP encryption is set on both AP's
WDS in enabled on both AP's

Still not working. What I'm I doing wrong here? In the WDS tab I
can enable WDS, but the only options I can chose of is WDS Root AP
and WDS-STA mode. Tried several combinations, no go.

What am I overlooking here? Can this type of access point (3CRWER100-75)
handle WDS? I can not select Repeater mode anywhere.

Thanks in advance,

Filip
