Merlin 378.55_0 on Asus RT-AC87U

[Moo]

All works great but for some obscure reason after 3-7 days the net stops for cabled users (like my iMac) but continues to work flawlessly for the WIFI users. I have set the lease time higher and it seems that it helped. However recently it has starte more frequently. The Asus are not in heavy use so it should handle the traffic just fine.

Any ideas?

I suspect something here: ...

TCP Timeout: Established
Default: 432000 (5 days)

I haven't experienced anything like that, my router (AC87U -378.55) is connected via cable to my iMac without any issues. Have you tried doing a reset to default settings and see what happens?
