 You could also use the APs in repeater mode with the same SSID, if you're 
 planning to use more then one AP.
 
no that is no very handy if want some performance, a repeater eats
bandwidth from the AP.  

Best for performance 
- big antenna's antenna's  (reduces noise from clients)
- channel planning
- ap's in bridging mode (no routing or NAT)

In a classic E.U (U.S.?)
- a server is in a server room
- ap is in the class room
- maybe use PoE (803.af) over your wired network

 Unless your school is very small, using dedicated wireless

 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!

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.

Best for performance
 - big antenna's antenna's  (reduces noise from clients)
 - channel planning
 - ap's in bridging mode (no routing or NAT)

 *Configuring your APs to use different channel from one another.

[Server-devel] Wireless Cards in the School Server

2009-03-08 Thread Xavier Ziemba
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?

Thanks,
Xavier Ziemba

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.

Cheers,
Dev
