Comment 17 for bug 352150

I'm not sure how helpful this will be but I finally solved this by ditching my AP.

I noticed that very often the AP (A D-LINK DWL-2000AP+) would often crash when I lost the connection. I didn't spot it at first because I was so busy looking at the laptop and trying to fix things there. I realised I could reliably cause the AP to crash and require hard-reboot simply by initiating a couple of large file transfers to the laptop. Most of the time it would be ok except when traffic was heavy.

So I er, bought another AP! I've got a Netgear WG602v4 and it's working very nicely with no change in config on the laptop.

I've made a few rough notes at
