I struggled/argued via CHAT because I DO NOT SPEAK with ExpressVPN whose Aircove router I use that they had to be the issue relying on information posted here, also my thoughts before I ever posted here and Comcast/Xfinity conversations and a modem swap for $$$. After a 4th agent at ExpressVPN and 5 days she agreed to let me roll back a recent 'firmware' which was quite an effort. The 'firmware' couldn't be downloaded using the Aircove, I had to connect PC to modem download 'firmware', reconnect everything and reset BUT it works!
