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.

Lonnie
