If it really is an AP, it won't do the job, as an AP cannot be a client to another AP. 802.11 DOES have the concept of a wireless backbone, called WDS (wireless distribution system), but it is not yet defined (Work In Progress: 802.11s, I am a contributor to the security features). So each vendor has its own WDS implementation (MIT's OnePC implements part of draft 1 of 802.11s). Of course there are devices out there that are referred to as wireless bridges (Linksys WRT54g is one) that act as a client and bridges an ethernet as a single client to the AP. Note that a wireless bridge is NOT an AP. Of course there are probably devices out there that can be configured either way Note, I work on the 802.11 standards and know them well, but I don't know of all the flavors of implementations out in the wild. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

At least when running the Tomato Firmware, the Linksys WRT54GL (L = linux) and WRT54G versions 4 and earlier (also linux-based) run WDS as hosts/clients very effectively. I run several GLs as access points across my lan with 0-2 more as WDS clients as needed. As a side note, Tomato Firmware allows you to adjust transmitter power up to 6 times the normal level and that has let me go through some very think brick walls to pick up remote network cameras. I should point out that both the host (access point) and client need to be WRT54G/L routers for the above scenarios to work. As RM said, WDS is vendor dependent.
