Morning All. I'm attending site where they have a 2820 installed but just used as a WAP controlled on the LAN by the SBServer.
They also have a 2920, connected by LAN1 to the SBServer, with WAN1 connected to their ISP's Bonder and their 3 x ADSL lines.

They've asked for a Guest WiFi account, so I thought I'd setup a second SSID on the 2820 and isolate the LAN. Of course, this wont work because the 2820 does not itself have the WAN connection to the ISP. So my question is:

Can I connect the 2820 lan port to one of the 2920's lan ports and get to the WAN that way? If so, what is the trickery of the lan routing settings on the 2920 that will need to be done?
(Of course I'll still need the 2820's original SSID to be able to get to the lan!).

Many thanks for any replies!
