Can you check if the unit is updated to the newest firmware? I suspect it is not. After updating please try again...

  Hi @jzchen 

 

I checked for updates over the last couple of days and all was up to date. As it happens there was an update last night, I have just updated and tried again. Still no success.

 

 

Hi  @Ryan 

 

Please see responses below in red. 

 

1. Is the VPN server you are attempting to connect to hosted on another device inside, or outside your network? Or, are you referring to a VPN service provider (e.g., NordVPN, ExpressVPN, etc.)? It is a remote server running Sophos VPN.

 

2. Is the alternative Wi-Fi connection also using your mobile ISP as its Internet source? Or is it an entirely separate network/Internet source? It is an entirely separate network using a cable connection to the alternative router. If I hotspot from my Mobile, which is the same ISP, then I can connect no problem. 

 

3. What are the types of devices that are having difficulty connecting to the VPN? All are Laptops.
