Sporadic Wifi initialization issue - xyzzy - 11-20-2020
I've noticed the Wifi sometimes doesn't working right. I first noticed this with the Manjaro ARM 5.9.8 kernel.
When the wifi is "bad", it still works, can connect to a network, send and receive packets, etc. But the packetloss is about 7% or more, which is really bad. Very noticeable with ssh as there are constant hangs. Web browsing one might just think it's slower than normal. When the wifi isn't in this bad state, packetloss is effectively 0%.
There appears to be something that happens when the wifi chip is initialized that causes this. When this happens the Wifi MAC address is different. Good state, I get one address. Bad state, it's another address.
Here's some the kernel log messages when it's GOOD.
