I have a SonicWall TZ170 Standard connected to fiber internet in a business office. A new behavior over the last week: The office loses all internet. Not only does the VPN to the home office go down, but they have no internet access at all.
The only thing that fixes it is resetting the SonicWall (they just unplug it and plug it back in).
Can you guys point me in the right direction for things to check when this happens?
