With "12.1.0 for XO-1.75, customized (build 22)" on an XO-4 B1 (software as it came from the factory, but sshd enabled), and an 8787 wireless card swapped in, I was noticing unusual latencies over ssh. It was bad enough it distracted me into investigating it.
Pinging the laptop showed 35% packet loss, and of those packets that were not lost many were delayed several seconds.
I managed to make this problem go away by shutting off NetworkManager and configuring the wireless interface by hand.
I will attach ping logs with (con) and without (sin) NetworkManager running.
With all the 5GHz channels available on the 8787 card, maybe scans take much longer and NetworkManager (or perhaps its clients?) are asking for scans often enough for this to be a problem.
