Packet loss extremely high on wifi (Nearly 100%) (BRM4331) (MBP 9,2)
I have a mid 2012 macbook pro running arch linux, everything has worked fine on it up until a few days ago. I have been using the b43-firmware-classic package as the network card is a BRM4331. A few days ago, I noticed the internet sometimes fluctuates anywhere from being slow to being so unstable that it is completely unusable. Running mtr on any address reveals very high packet loss. Most of the packet loss occurs on the very first step (_gateway). This packet loss ranges from about 5% to 90%. I've tried upgrading to b43-firmware (from b43-firwmare-classic), but it doesn't seem to change anything. I am using NetworkManager.
Any help or pointers would be appreciated as I really need a computer for school, thanks!
Note: This happens no matter what network I am on, and other devices on the same network do not experience the same problem
Note 2: Everything works totally fine on ethernet (0.00% packet loss)
