MikroTik wAP ax, when dropped from 2 meters, cracks. 🤦♂️ Still works though. Luckily I was installing mine under the roof overhang, so I should be fine 🤞 with water getting in.

My main home server (running Proxmox) is now connected to upstream switch using 10G (copper). Of course it's mostly useless because anything upstream is just 1G. But I'm working having my office connected with something faster than 1G.
