Monitor your network configuration [dneary@host] $ip monitor all [dneary@host] $ip-s link list wlp4s0

The ip monitor command can be used to monitor changes to the routing table (network addressing on the network interface) or changes to the ARP table on the local host. This command is particularly useful when debugging network problems related to containers and networks, such as when two virtual machines should be able to communicate with each other, but they cannot.

When using all, ip monitor reports all changes prefixed with [LINK] (network interface change), [ROUTE] (change routing table), [ADDR] (IP address change), or [NEIGH] (independent of horse-related changes related to the neighbor's ARP address).

You can also monitor changes on specific objects (for example, specific routing tables or IP addresses).

Another useful option for many commands is ip-s, which provides some statistics. Add the second-s option to add more statistics. The ip-s link list wlp4s0 above gives a lot of information about the packets received and sent, the number of packets dropped, the errors detected, and so on.
