Re: [Server-devel] Large groups of XO-1 do not work with access points

There seems to be a lot of speculation, so I'll add more technical details on what Terry and I have been investigating. 1. sometimes, an active scan by the XO-1 does not have the access point listed in the scan results, despite the XO-1 transmitting an acknowledgement to the access point, 2.

G'day Anne, Yes, a manual sudo iwlist eth0 scan in Terminal, or an iwlist eth0 scan in console, until the AP appears, is all it takes to fix. You derived an independent workaround for the same problem! If you have some XO-1 that work and some that don't, then you might have one broken antenna

I've seen XO-1s randomly drop off the AP in Paraguay. I *think* we solved it by disabling 802.11s (the mesh network). This can be done at boot time by setting a parameter of the libertas kernel module. Sorry for being vague, it's been a long time ago. On 02/07/2014 10:10 AM, Adam Holt wrote:
