"iw dev" seems to say that device is using the 2.4Ghz side, at least in the working configuration. phy#0 Unnamed/non-netdev interface wdev 0x2 addr a4:34:d9:0e:20:d7 type P2P-device Interface wlp1s0 ifindex 3 wdev 0x1 addr a4:34:d9:0e:20:d6 type managed channel 1 (2412 MHz), width: 20 MHz, center1: 2412 MHz I have no idea why it wouldn't connect to the 5GHz network, but it might just be far enough away (a couple of walls, not so much distance) that it is borderline. Both networks have the same essid and password, maybe I should add a separate 5GHz network to make it easier to say "connect to that one" for testing, in case the trouble happens with the 5GHz side only.
