 Posted: Sat Sep 16, 2017 3:34 pm Post subject: prevent wpa_supplicant + network-manager from switching SSID |
 |
|
I have a wireless home network with both 2.4 and 5 GHz channels. Each has it's own MAC/BSSID but share an SSID.
I only want to connect to the 5 Ghz channel (YY:YY:YY:YY:YY). So I have blacklisted the 2.4 Ghz channel (XX:XX:XX:XX:XX) using nmcli. When I do "nmcli connection myssid show", I see:
| Code: | | 802-11-wireless.mac-address-blacklist: XX:XX:XX:XX:XX:XX |
However, I can see in my system log that wpa_supplicant continually tries to hop to this channel when the signal becomes poor!
| Code: |
