Troubleshooting A-3
Power outages
If you suspect that power was restored after a power outage, and the Netopia R2020 is connected to a remote
site, you may need to switch the Netopia R2020 off and then back on again. After temporary power outages, a
connection that still seems to be up may actually be disconnected. Rebooting the Router should reestablish the
connection.
