WLAN doesn't reassociate with known access points

[wad]

The expected behavior of an XO is that if it doesn't find a school mesh (or "laptop as MPP" mesh), it will try to associate with WiFi APs that it has previously been associated with.

In the 69x builds (particularly 699), this has not been working reliably (for example, see: http://wiki.laptop.org/go/Collab_Network_School_Wifi_Tests#Test_0323K )

But with build 703, I'm seeing that association with a previous selected access point tends to work, with occasional failures. Attached are logs taken from the same laptop. Once when it succeeded, and once when it fails.

In previous tests, I noticed a zero length /home/olpc/.sugar/default/nm/networks/cfg file, which could have contributed to the problem. That file was verified to have the correct information in these tests.

Looking at the failed logs, it successfully DHCP'd with the known AP the first time, then failed when it tried to renew the second time. This is not a stellar example of the behavior seen. I will try to get logs from a machine failing upon first boot.

This is possibly a duplicate of #4975.

Can we restest this and close it or reproduce it?

On recent XO-1.5 builds this is fixed. Closing.
