Thank you for the replies. My home network blocks google, my verizon phone tethered to the MT1300 ostensibly does not. Regardless it seems there is no suggested fixes for this or that it’s even a problem. I want this to work. I disabled whatever the mwan3 function is under /etc/config/mwan3 under the “tethering” section, and for 2 days solid, no problems with additional TTL target entries, solid white light, steady internet, almost like it was working as designed.

Plug in a hardwired client into the LAN port (RJ45), and everything starts happening again. Light changes to blue with slow flash, internet drops, multiple TTL entries showing up in iptables.

Is there a way to fix this, I have about 20 days left before my return window closes and I don’t want to miss that. If this is expected behavior please advise. Thanks!
