Looked at everything I could think of and am at my wits' end... This is what it looks like:
and so on forever: every dot is ten pings to the nearest hop (i.e. the gateway assigned by the ISP's DHCP), number is "replies lost out of 10". Ping was running on a router -- running it on a box inside the LAN does the same exact thing, synchronized. So about 25% loss coming up every 70 seconds or so. Now, what it isn't:

Ping was running on a router -- running it on a box inside the LAN does the same exact thing, synchronized. So about 25% loss coming up every 70 seconds or so. Now, what it isn't:
- ISP issues: I connect my Linux box to the modem directly -- nothing like this happens
- Bad firmware: long history -- first the issue came up on an RT-AC68U couple months ago. I have tried both Merlin and Asus f/w, different versions - nothing helped. Finally I bought a brand new ZenWiFi AX (currently at 3.0.0.4.386_43181-g6099e58) and retired the AC68U to the duties of an AiMesh node upstairs (currently running 3.0.0.4.386_43129-g60defb2). The problem went away and I breathed easily. AND NOW IT'S BACK!
- Running OOM - nope
Mem: 290644K used, 219520K free, 1540K shrd, 16616K buff, 50696K cached
- Running low on file space - nope
/dev/root 53632 53632 0 100% / devtmpfs 254976 0 254976 0% /dev tmpfs 255080 188 254892 0% /var tmpfs 255080 1136 253944 0% /tmp/mnt ubi1:data 4584 80 4232 2% /data tmpfs 255080 1136 253944 0% /tmp/mnt tmpfs 255080 1136 253944 0% /tmp /dev/mtdblock9 48128 3540 44588 7% /jffs
- Running hot - not visibly so; couldn't find the temp gauge in the current f/w UI but here's this:
# cat /sys/class/thermal/thermal_zone0/temp 68493
- Logs - nothing whatsoever of interest in dmesg, /var/log or /jffs. Certainly nothing that would come up with that sort of period.
- Top activity - nothing correlates.
Thanks in advance,
