Sophos looses internet and vpn access connection periodically

Question

Hi, 
 I've been experiencing loss of internet connection and VPN on Sophos XG Firewall. And to resolve the problem I have to reboot the appliance. This happens so frequently and I can't figure out what it is cuz I see no Logs indicating the problem.

Possibly, it is your ethernet card drivers and Sophos. You will need to look at your Kernel Messages which will most likely show your card up then down consistently. Happens in both UTM and XG because crap drivers that no one wants to address. I've addressed this in a previous post where I had the issue in both versions of the firewall. 9.7 killed eth0 for me... It had to be 'taken out'. - Hardware, Installation, Up2Date, Licensing - UTM Firewall - Sophos Community 
 Look for 'e1000' in the errors. If you are seeing similar to what I posted, there is your answer.
