4 different cameras - 3 fine, 1 won't connect

I have 4 different Aqara cameras - 2x G3s and 2x E1s. In either the Aqara app or in HomeKit, the 2x G3s and 1x of the E1s will start showing video nearly instantly. 1x of the E1s times out, won't show video, goes offline in HomeKit, etc. This is a replacement for another E1 that was doing the same thing.

I can ping any of the working cameras and get ~7ms from my laptop on wireless. The misbehaving one will go from ~7ms to ~2200ms to just timing out. If I power-cycle the camera, it seems to be okay...but as soon as I start streaming video from either Aqara app or HomeKit, it then goes bad with the high pings and timeouts. The pings will eventually go back to normal.

I would think it was something with my network/wireless, but the other cameras (and a Logitech doorbell on HomeKit) connect just fine. This is a replacement from Amazon just out of the box too. Possible I got 2x bad ones?

The SSID is 2.4Ghz and 5Ghz without band steering. I do see all of the cameras on 2.4Ghz.

What's crazy is this was all working fine until this one camera started going offline.

Anyone have any thoughts? Or should I just ditch this and get another G3?
