Figures out my Wi-Fi connection problems are unrelated to the new release:
My Wi-Fi adapter is Mediatek:
Network:
Device-1: Realtek RTL8125 2.5GbE driver: r8169
IF: eno1 state: down mac: <filter>
Device-2: MEDIATEK MT7922 802.11ax PCI Express Wireless Network Adapter
driver: mt7921e
IF: wlp13s0 state: up mac: <filter>
Prior to disabling MAC Randomization, it was doing this at random:
Nov 28 06:24:46 XXXX NetworkManager[921]: <info> [1732796686.2121] device (wlp13s0): set-hw-addr: set MAC address to B2:B2:BC:34:5F:C1 (scanning)
Nov 28 06:24:49 XXXX NetworkManager[921]: <info> [1732796689.0995] device (wlp13s0): set-hw-addr: reset MAC address to 4C:82:A9:40:FA:8D (preserve)
Nov 28 08:40:20 XXXX NetworkManager[921]: <info> [1732804820.9120] device (wlp13s0): set-hw-addr: set MAC address to 3E:F2:8B:A1:1F:FD (scanning)
Nov 28 08:40:21 XXXX NetworkManager[921]: <info> [1732804821.1847] device (wlp13s0): set-hw-addr: reset MAC address to 4C:82:A9:40:FA:8D (unmanage)
I checked the Install log and nothing was upgraded at the time this started. That got me thinking to check my router, and sure enough my Asus router (ZenWifi) got a firmware update, and the problem has been happening since then.
The fix was to turn off MAC Randomization in grub by creating:
/etc/NetworkManager/conf.d/wifi_rand_mac.conf
and including the following lines:
[device]
wifi.scan-rand-mac-address=no
Then update-grub and reboot
I think I’ll go back and test after the next firmware update.
