First of all, I know everyone (aprt from 8xxx/9xxx users who wants
things to work again) now wants speed and suspend/resume.  Thing will
comes, patience please.


If you have a single-SSID for both 2.4 and 5  I think you can add two
entries in wpa_supplicant.conf with different frequencies and use
priority for them appropriately if you prefer 11g to 11a.

Alternatively and probably better than frequency is to use the bssid=
often just differening by the last bit.

I used to use something like this for testing:

network={
 	ssid="abcdef0123"
 	bssid=01:02:03:04:05:06
 	proto=WPA2
 	psk="abcdefghijk98765"
 	priority=50
}

network={
 	ssid="abcdef0123"
 	bssid=01:02:03:04:05:07
 	proto=WPA2
 	psk="abcdefghijk98765"
 	priority=40
}


I know the man page for wpa_supplicant.conf is a bit sparse and
/usr/share/examples/etc/wpa_supplicant.conf is a bit tidious to go
through as wifi is complicated these days ...

Hope it helps,
