when I try to add a wifi connexion to a bond, I have this folowing error:
linux:/home/user # nmcli con add type bond-slave ifname wlo1 master bond0
Connexion « bond-slave-wlo1 » (14778c00-d1a4-41af-8883-daa895c3de30) ajoutée avec succès.
linux:/home/user # nmcli con up bond-slave-wlo1-1
Erreur : l'activation de la connexion a échoué : No suitable device found for this connection.
In bond-slave-wlo1 I have type=ethernet even if my interface is a wifi card!
I’d first ask you what your objectives are and a description of your WiFi infrastructure (ie details about your AP and if you have multiple APs in the area) to determine if what you’re trying to do will achieve what you want.
Ethernet is basically a serial technology which means only one packet “on the wire” (In the case of WiFi the connection) at a time. Some AP models support multiple antennae that theoretically can multiply throughput.
Compare to known and working bonding techniques using wired NICs.
Ethernet is the basic communication technology (vs other, less seen like token ring) in everything including wireless and wired. Ethernet is the common networking technology for practically all networks around us today (except straight serial connections used by BT and RS-232 connections which even they sometimes are implemented with an ethernet layer on top of the base).
I have a wifi connexion (wlo1) and a shared 4g connection (the interface of my phone is recognised as ethernet; eth0)
I whant to use this two internet connextions at the same time, in order to increase my bandwidth.
My problem is about nmcli, bonding and wifi interfaces, because load balancing is already set for my phone. I have tested with an ethernet connexion and my phone, It works ! But I cant add à wifi interface to the bond.
Although probably not a problem, you should probably post your list of available network interfaces. This is useful so that not only can we see your physical interfaces, we can also check the name you’ve chosen for you bond as well as any interfaces already a member of your bond
nmcli con show
Based on what you posted, I suspect that although you added wlo1, you attempted to activate (bring up) wlo1-1 which is likely an error.
I’m not sure that the type of connection may be important here… After all, you’re bonding a wired (802.3) connection to your wireless phone carrier with a WiFi(802.11) connection. When you bond two different types of interfaces, I don’t know that there is an interface name that can describe this, so whatever results, is.
