3Com Wireless 7760 - Wireless Workgroup Bridge mode - how to set up
VLAN?

Hello,
I'm working with two 3com Wireless 7760 a/b/g PoE Access Points: the
first one is configured as "Access Point mode" while the second is
configured as "Wireless Workgroup Bridge mode (Client Bridge mode)".

The client (second one) is able to connect to the Access Point (first
one) so everything is working ok.

Now I want to set up both devices to use VLAN. This is because I need
to connect these two devices to two different PCs (using network
cables): these PCs will use VLAN (they have network cards capable of
VLAN tagging), I want to test end-to-end perfomance between the two
PCs.

So far I've managed to set up VLAN only in the first AP (the one
working as Access Point).

Anyone know how to set up VLAN on the AP working as Wireless Working
Bridge (Client Bridge)? Is it possible?

There is no "VLAN managment" option in the browser interface if you
setup the AP in this way...please help me :-)

Thank you,
Francesco
