|
Has anyone recently had their b43 broadcom driver wifi (bcm4318) suddenly become very slow, it doesn't appear to be losing packets but despite the WAP being within 10 feet and LOS of the antennas, it's very very slow.
It had been working just fine up until recently. Unsure what happened to it (using new 3.17.7 kernel and networkmanager are two things that happened recently but it seemed to have happened prior to these...
Slow... slow as in... Dial-up speeds. (!!!!)

Radio in the wifi card died?

For some reason a power cycle at least temporarily cleared things up. Weird...
I guess this is sort of what to expect in reverse engineered drivers?
Still better than nothing. Or Ndiswrappers...

| I wonder if your laptop was overheated and that had anything to do with it. Just a thought. |

It could have, but it had been able to work through the same situation many times before. Maybe it is time to get the fans cleaned out, not sure... Alas remote admin is tough...
