Comment 34 for bug 488340

@reason: broadcom uses firmware that is exclusive to microsoft. I think
the easiest way to solve this is switch to a generic atheros or intel wifi
card. The broadcom driver is proprietary hence it will take longer to
resolve since broadcom does not seem to put sense of urgency to fix this.

come back to life without disconnection. The disconnections are quite
frequent, I would say once every five minutes.

had to muck with kernel stuff under Ubuntu, so I might just chicken out and
continue to use the 802.11b device.
