Re: [Server-devel] wifi setup
Tom We use multiple APs in schools set up in simple AP mode, using DHCP (not fixed IP), the same SSID exactly, and only one network icon appears in neighbourhood view. Same capitalisation is important. But you never have to choose which one it should connect to. At the current school we had to accept some 120 sector APs as there was no omnis in stock. Walking about with Terminal Activity running and pinging, you could clearly see where it hopped onto a new AP. Can't add much more from technical point of view. We've used Linksys W54 types, EnGenius various types, DLink cheapo and more expensive types, and usually in the default state with minimal config - just SSID, simple access mode and DHCP client. Everything on the eth1 network.

That is true -- with build 8.2.1 sometimes the XO switches from one AP to another needlessly. This does not happen in newer builds. We diagnosed the problem down to wpa_supplicant deciding to switch AP. In the same investigation we saw that the libertas driver was not resetting tx failure count periodically -- this may be influencing wpa_supplicant. cheers, m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel

Re: [Server-devel] wifi setup
Different OLPC OS builds present access points with same essid in different ways. There was a problem with multiple access point presentation fixed somewhere along the way in development, but I'd have to go looking for it. Which build are you working with?

Re: [Server-devel] wifi setup
I was under the impression that this required 802.11F capable APs to work properly. But I'm no expert. Anyone better informed care to educate me ?
