Eero keeps disconnecting dozens of times a day

I've had 3 Eero units for more than 2 years, and up until a month or so ago, had little problem with them. Nothing has changed. My ISP is the same. My modem is the same. All units are in their same places. One day, we started losing our internet from anywhere between 10 seconds and 2 minutes. Whenever it happened, I would unplug and plug in the Eeros, let it reconnect, then we'd be back in business. It started happening more frequently. I ran tests and made sure it wasn't our ISP. They reported no downtime. My ISP modem didn't show any disconnects in their log. When our internet did go down, our base Eero would sometimes (but not always) turn red, yet my modem was still connected. I hardwired a computer just to the modem, and it indeed stayed connected to the internet...I've also kept logs for said computer for more than a day, and zero disconnects. It's been isolated to the Eero(s). The base is what loses the connection. Thus, the internet for the entire house also goes down. It has become so bad lately, kicking us off of our video calls for work, knocking out our logins for gaming, video streaming just stops. So, after much research over the past month, I upgraded my base Eero to the 6. Everything reconnected flawlessly....and then the intermittent drops kept happening. No matter how many times I reboot, re-add, replace, it just won't stop dropping. Here is this morning's connection log. We just can't operate with our connection dropping multiple times per hour. I haven't performed a hard reset to start from scratch, nor have I put my modem in bridge mode, but aside from that, does anyone have any ideas on what to do?
