Understanding wifi hardware balancing

Support Network
1

I have two wifi cards, a very slow one 2,4GHz internal (wlo1) and a faster external one 5GHz (wlan0).

Initially I detected that my connection were always slow, so I created a secondary connection specifying the cards for each one and the priorities. I can´t find any improvement however. I must blacklist the internal card in order to get an improvement.

I know I can do some bonding, but for some reason that doesn´t work. The bonding always defaults to the slower card.

Is there any way to properly configure the networking for this laptop? I want to still use both cards to improve the connection stability.

I think you need special software for this, such as Speedify. It’s in the AUR. It’s not cost-free, I guess.

Does wlan0 drop out often?

If not then just use that.

Otherwise perhaps this will help.

I tried the bonding, but when placed both at the same time as slaves, the bond just prioritizes the slow one. For now I just blacklist the slow one and use the fast one.

The wiki says you can configure a preferred interface. If you’ve already done that correctly then perhaps the interface isn’t available at some point so it falls back to the one that is. If that’s the case then a delay may help. :man_shrugging:
