Hello!
Using b43 I am able to connect to an AP, but experience very high
rates of packet loss (~30-80%).
The machine is a MacBook Pro 10,1

My other (linux based, of course) machines can connect to the access
point reliably, and this machine experiences high packet loss when
connected to any access point, so I think is a problem with this
machine.
I've tried the Broadcom STA drivers from package
broadcom-sta-dkms/xenial,xenial 6.30.223.271-2 all and the Linux STA
drivers from bcmwl-kernel-source/xenial 6.30.223.248+bdcom-0ubuntu8
amd64, both have the same problem with high packet loss.
I've tried connecting directly using wpa_supplicant instead of
network-manager, to the same effect.
dmesg attached.
Any help would be much appreciated.
Thanks!
