In my home, I've got a MoCA modem / WiFi access point / router (provided by my cable company) and behind it, a Netgear R6400v2 running DD-WRT v3.0-r45493 std (01/19/21).

When I connect to the MoCA modem's access point and run 'ping 8.8.8.8' , everything works all right.
When I connect to Netgear's access point and again run the very same 'ping 8.8.8.8', I get about 5-15% packet drops:

Code:

> ping -t 8.8.8.8
Pinging 8.8.8.8 with 32 bytes of data:

Ping statistics for 8.8.8.8:
    Packets: Sent = 49, Received = 45, Lost = 4 (8% loss),
Approximate round trip times in milli-seconds:
    Minimum = 10ms, Maximum = 32ms, Average = 13ms


Needless to say, networking works poorly. It really looks like the Netgear is to blame here.
Problem is, everything has been running like this since 2021 and I haven't changed anything recently so I am at a loss what this might be.

How to further debug the issue?
