After a power cycle I suddenly found that CTF was available, though there are no options for FA. I've selected it and applied. I've also pointed the router to a few top-level DNS servers and checked the box to ignore ISP DNS. The problem still persists. I'm trying to get Comcrap to extend the lease time, but I have to constantly wade through low-level tech support that wants me to try a million things that I've already done.

Even though I think the premise is to be able to load those kernel modules on the fly, a reboot is always a safer bet.

FA requires more than one reboot, due to in chip FA accelerator I think its not enabled by default, and you should only use FA if you have gigabit WAN, less CTF should be fine.

I think your Asus should have FA available, not sure not looked at code, the syslogs will tell dmesg also if you grep for FA. But using FA will have a great deal of caveats attached.

Okay, if FA isn't necessary, then that's not an issue. CTF is enabled at least.

It happened again. Dropped the IP for a few seconds, reset the uptime counter. Right in the middle of an important call, and I'm in a near dead zone for cell service. This is rapidly making my nice, expensive router a borderline paperweight. Please let me know if there's anything I can try, or even a debug build I could load onto the router to provide further details.

The logs look a little different now. Maybe it's relevant, maybe not, but I figured I should update. This seems to coincide with another disconnect/reconnect and the last log entry was about a half hour prior. I did enable IPv6 yesterday, but it seems that Xfinity isn't using it, or maybe I need to do some additional work to get an IPv6 address.

I'm guessing that switching over to CTF is probably changing a few things and that maybe some of these entries are incidental.[/quote]

PaulGo has dealt extensively with Comcast's IPv6:

[SOLVED] WAN IPv6 Disabled
R7000 lost Comcast IPv6 WAN recently
WAN support IPv6
Is IPv6 Useful and Should It Be Enabled in DD-WRT

I was able to acquire an IPv6 address from Comcast along with the usual IPv4. Didn't seem to make a difference, though.
