Just found this thread as I’m trying to troubleshoot my GL-AR750.

It’s worked fine with xfinity for months, but I can’t get it to work all of a sudden. I turned off the DNS setting that was mentioned. I tried updating and reverting the firmware. The oldest version I found was 2.273, so that was the closest option to 2.03.

I haven’t had any consistent luck with any solutions though.
