I recently bought a pepwave max transit LTEA and using it in an urban environment with an AT&T card and Google Fi sim card (T-Mobile) in it. Both have strong signals.
I am using my work laptop where I setup multiple VPN tunnels from my laptop to connect to servers in the cloud, and I use secure https connections with Signle Signon tokens. When using the AT&T sim card it keeps disconnecting the VPN tunnels and invalidating the SSO tokens for secure websites. When I use the Google Fi card, it doesn’t have that issue. But now I reached my data limit, and can’t use that until the next billing cycle starts. The symptoms I’m seeing is that tunnels just disconnect, websites show ‘invalid SSO token’ and ‘HTTPS -1 error’ messages
My UNeducated guess is, the disconnecting issue is because it’s doing carrier aggregation and connecting over multiple bands at the same time, and that somehow invalidates the vpn tunnel? Whatever the cause is, how can I fix this issue?
