Hmm. "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.
