Thanks, Xavier Ziemba ___ Server-devel mailing list server-de...@lists.laptop.org http://lists.laptop.org/listinfo/server-devel You should be able to run PCI wireless cards with XS as long as Fedora supports the drivers. The only thing that may get in the way is the way wireless cards get their labels allocated (wlan0 instead of eth0, etc) in which case the interface bonding will break (IIRC, the labels on the XS are eth0, eth1, etc). I haven't tried it, but its worth a shot. Can you report back and tell us if it worked?

Re: [Server-devel] Wireless Cards in the School Server
Unless your school is very small, using dedicated wireless interface in the server is probably not a good idea. We suggest dedicated access points as schools with more than 40 - 50 students will need more than one access point, and they are best spread out (i.e. not all the antennas are within three feet of the school server.) There is currently no effort in the XS configuration scripts to recognize and properly configure such an interface. That doesn't mean it won't just work, and I'm sure it could be made to work with minimal effort. As Sameer said, let us know what you decide, and what works for you!

Re: [Server-devel] Wireless Cards in the School Server
I believe most AP's are plug n play on the XS, we'd tested quite a few including the Active Antenna's that OLPC used to ship earlier, which worked fine in AP/Bridged/Managed mode, though used to crash every once in a while and required a reboot. The interface labelling as Sameer pointed out was a bit tricky though. Also, if I remember correctly we'd gotten the best perfomance with 20 or so XO's to an AP. You could also use the APs in repeater mode with the same SSID, if you're planning to use more then one AP.

True, using an AP as a reapeater does compromise on your bandwidth, guess its only helpful in cases where you're wanting to extend coverage and not ness improve connectivity.

[Server-devel] Wireless Cards in the School Server
I've been working on configuring an XS server for the Cambridge Friends School in Massachusetts and have a couple of questions regarding wireless networking and the XS server. Does the XS software support automatic configuration of PCI wireless cards within the server itself? The documentation on the OLPC wiki seems to suggest that using separate wireless access points through a wired interface is supported; would this be a better solution for this deployment? Also, how would I go about configuring the appropriate links between network interfaces if I used wireless cards within the server?

Re: [Server-devel] Wireless Cards in the School Server
Hi Xavier, You could also look up the archive at http://lists.laptop.org/pipermail/networking/ Guess hasn't been very active lately, but then has plenty of info and reference to the wiki. Should get you started and help you with most of your queries.
