I just bought a Sonicwall SOHO which is the new model that replace TZ105, TZ 205 series.
The network stops working intermittently. The whole network is down after every 30~70 minutes of uptime, no Internet, cannot access the router admin panel. I have to hard restart the router to access it or get the internet back online. I found it could be caused by the DHCP server of the router. When the network is down, the server stops assigning any IP addresses.
Can anyone give me some clue what can cause this ? Any resolution that I can apply ? I have been dealing with this whole day, I am hoping someone can give me some direction. Thanks a lot.
Update: After the router is down, I tried to set up IP address manually and ping the router. The ping return "destination host unreachable".
