This sounds like a problem with the Broadcom drivers - this was a
known problem with early versions of bcmwl-kernel-source 6.* (5.* was
fine), but I'm not sure if it has been addressed. The easiest
workaround I found for my Mini311c was to use the b43 driver
(firmware-b43-installer) - other people gave up and put in an Intel
wireless card instead (not an ideal solution but it works).

I haven't used my 311c for a while (since I got a refurb X61) but the
bug report [1] has a link to an updated package from saucy [2] that's
been reported to fix the issue. Of course, if you don't have internet
access that doesn't help much...
