Ya - wired is also affected.  Latency has gotten pretty bad.  10ms wired and as bad as 60ms wireless....and I can't get more than 400 mbps standing right next to the eero Pro 6E with wired backhaul.

My network went crazy yesterday. 60+ ms latency wired 200+ ms wireless. I had to delete the network and hard reset everything to get it back up. The jitter remains high after the hard reset. 

So this might end up being a recommendation for everyone frustrated with their eero system.  I was ready to take my entire kit and burn it given all the problems I was having with it.  So, I decided to do a hard reset and rebuild the network from scratch.

Knock on wood (or touch would if you're from the UK) but it's actually been running great for the last week or so.  I even got for a brief moment 780 mbps download on a wireless connection (MSFT Surface Laptop) - with Speedtest giving a final score of 650 mbps.  I also had one eero 6+ that was destroying my network when plugged in to wired backhaul.  Tech support thought there was a short on the ethernet cable which I couldn't replace because it was in-wall. Nope.  Even that "AP" has been working great via wired backhaul.  

So bottom line, if you're having issues with your eero, maybe a hard reset will fix your issues.  It took me less than 30 minutes to rebuild my network with a total of five eeros. So glad I did it.
