It depends on how mining client developer handled such situation.
Usually, the mining client will drop the connection from the pool, stop mining, and then trying to reconnect. Pool sends the problem that needs to be solved and the hardware solves the problem and sends back the solution - if there is no internet connection pool cannot send the problem and hardware cannot send the solution.
To check your internet connection use command
netcheck - it will show you to which endpoints you have the access and to which you don't. If you can't reach any of the endpoints, there is some general internet connection issue going on.
mworker accesskey workernamewhere
accesskeyis your access key and
workernameis your worker's name. This will refresh your host file. After that write
dhcpto refresh the dhcp connection as well.
