I use this in my RV with a Surf SOHO and it works very well except for one rather large caveat that I think you guys need to at least document.
If the WiFi WAN network goes down for any reason, like say driving to another campground, the WiFi LAN on the same frequency will start experiencing more than 10% packet loss due to the router re-scanning for the WAN network every few seconds. You must disable WiFi WAN to allow your LAN to work properly.
This could be made much better if Peplink lowered the scan interval when a WAN network is not in range, like say 60 seconds, even better would be a setting that adjust the scan interval defaulted to 60 seconds.
The best solution is two separate WiFi radios such as a MAX HD2, but just lowering the scan interval would resolve nearly all issues, causing a little packet loss every minute or two is not bad, every few seconds is very bad.
