We've been running a 655 as our main router since last year, has worked very well for 10 computers in a large building, at least for wire. I wanted to get a better wireless signal in part of the building, especially for visitors, so I got a second 655. After a little fiddling, I got it to work ok as an access point for wired and the main wireless. However, the guest zone will not acquire an ip address for anything connected to it. In reading some posts, I'm afraid that the guest will only work on the WAN connected router running the dhcp server. Can anyone confirm that this is the case or might there be some way to get the guest working on the second router.
