Comment 10 for bug 588375

For testing purposes, I am trying to download ubuntu's iso.

As Igor suggested, I tried manually assigning the IP address but I still get random disconnects while downloading the file.

I attach the syslog at the time of disconnect, where you can see:

wlan0: deauthenticated from 00:1e:e5:7a:44:60 (Reason: 14)

Influeced by the original poster, I have also tried a more recent networkmanager (the https://launchpad.net/~network-manager/+archive/trunk PPA), but without any luck.
