Thanks Lonnie
Hmm that may have something to do with it. Might also be when it fails over to
4G.
As most of my VPN's carry voice only, I think a standard MTU of 1340 for all my
systems should be fine. What do you think?

Hi Michael,
I have not experienced anything like that, WireGuard connectivity is rock
solid for me.
I don't recall later WireGuard versions having any fixes for what you are
describing.
Just guessing, the standard MTU for WG is 1420 (1500-80), if you have a
PPPoE connection with a MTU of 1492 you might try setting the WG MTU to 1412
(1500-8-80) or lower to test.
I'm testing a 4G-LTE/5G fixed wireless internet service from T-Mobile, they
use Carrier Grade NAT (CGNAT) for IPv4 which lowers the MTU to 1420 (just like
WG) so WG needs a MTU setting of 1340 to work over the CGNAT or else it hangs.
