Changing default WIFI connection from repeater to router in Ubuntu 18.04

  • 772

I am using a repeater on my network. My system settings only shows one device name for a WIFI connection. It is defaulting my WIFI connection to the repeater instead of my router. iwlist scan shows both the repeater and router. How do I change my default connection to my router? Im guessing by MAC address somehow?

nmcli device wifi list returns-

My system is picking the weakest signal but the highest rate. I don't want that. My router is 10 feet away from my laptop.

Here is the short version of iwlist:

iwlist scan
wlp2s0    Scan completed :
          Cell 01 - Address: 3C:37:86:12:A3:A8
                    Channel:1
                    Frequency:2.412 GHz (Channel 1)
                    Quality=48/70  Signal level=-62 dBm  
                    Encryption key:on
                    ESSID:"trinity"

      Cell 03 - Address: C0:C5:22:4C:9E:D0
                Channel:1
                Frequency:2.412 GHz (Channel 1)
                Quality=61/70  Signal level=-49 dBm  
                Encryption key:on
                ESSID:"trinity"

It is MAC C0:C5:22:4C:9E:D0 that I prefer to connect to.

    I would discourage tying your computer to only the router. The whole point of the router and repeater is to let the computer select the strongest signal to connect to.

    However, to do what you wish, you'll need the SSID and BSSID of the router. Edit an existing wireless connection profile that already connects to the desired wireless network. The SSID will already be filled in. Now select the BSSID that matches your router, and you're done.

    The BSSID can be found on the MAC address label on the router, or by using the nmcli device wifi list command, or by clicking on the down arrow in the BSSID field.

    enter image description here

    Another thing that can be done is to create two connection profiles, named, say, Trinity-Router and Trinity-Repeater, each hardwired to a different BSSID, and assign priorities. Use nm-connection-editor...
