FWIW, I run Attitude Adjustment on 2 wzr-hp-g300nh2's and on one
wzr-hp-g300nh, not the same but similar to your device.
The wzr-hp-g300nh does indeed show a large quantity of packet drops on its
internal LAN, and I've found no root cause. Likewise, I stopped using the
unit's wifi interface entirely (in lieu of just using wired routing), due
to wifi traffic periodically causing the internal LAN, both wired and
wireless, to randomly freeze for 30 seconds.
On the wzr-hp-g300hn:

My guess is that the wzr-hp-g300nh is defective, and/or OpenWRT support for
it is not 100%. The packet loss is not adversely affecting my usage, and I
will replace the unit with something else when opportunity allows.
