Hi,
I apologize for my first message, it was not clear.
I should have mentioned to replace <connection name> with the actual
name of the connection (as listed by `nmcli connection`).
Sometimes, my wifi connection (handled by network manager) gets
whimsical and the suggested command fixes it.
However, it does not apply in your case, sorry.
