I’m thinking of getting Surf On-the-Go as a 3G/4G failover router for a few critical devices that have to stay alive during outages.
I will need to use WiFi as WAN to connect Surf On-the-Go to my existing main WiFi, as the primary WAN connection (I would prefer to connect to WAN using the wire, but unfortunately the router’s only physical port will be occupied for LAN because one of my devices is wired). 3G/4G will be the failover.
Is WiFi as WAN generally stable enough to be the primary WAN, or is it really intended more for temporary failovers? I need it to be reliably connected for days/weeks unsupervised with no ability to reboot/reset the router manually.
The WAN WiFi signal will be stable since I will place Surf On-the-Go right next to the WAN WiFi source (my main router), but could there be eventual interference between the WAN WiFi and the LAN WiFi provided by Surf On-the-Go itself, or any other issues? Somehow I feel that WiFi as WAN as primary connection is not going to be as stable as a wired WAN, and may require periodic router reboot, are there valid reasons for such a concern? I see posts on other Pep router models where people lose internet connection on WiFi and require restart/reconnection.
