I've got Firmware: DD-WRT v3.0-r44483 std (10/02/20) running on 2 Netgear boxes, one r7000p, and one r6400v2. I'm seeing REALLY high eth TX error rates on both. Where should I look first to diagnose this?
Both boxes have been up for about 3 days, and have the following error counts in ifconfig:
r6400v2 is simple, single store-bought cat 5e cable to linksys gigabit switch, then upstream to larger gigabit switch, then upstream to cable modem. total cable distance from r6400v2 port 2 through 2 switches to cable modem is about 50 feet.
r7000p is more of a workhorse but same basic setup. Handmade cable from r7000p port (can't recall which one) to wall jack up through attic to larger gigabit switch, then upstream to cable modem. Similar overall cable length.
I don't know how to map from physical ports to eth1, eth2 ports. I'd appreciate some help. However, based on where the error counts show up in the web UI, those errors are coming from the wifi side not the ethernet side.
current r6400v2 after upgrading to DD-WRT v3.0-r44538 std (10/13/20) and running for just a few minutes is

I've always had high tx errors on wl0 which only seems to happen when using my laptop with an intel adapter, in total I have 21 devices connected through wifi and as long as the laptop isn't connected the tx errors stay between 3-15. what is your percentage bar reading? Mine is 100% with the worst i've seen being 99%
