Regret getting the 6

I “upgraded” to an eero 6 AX-1800 Dual Band Mesh last week, and ever since, my internet connection has dropped to a crippling 4Mbps. I replaced the modem, moved the beacons around, preformed all the usual recommended steps. Nothing seems to improve. The connection drops constantly.

I’m on a 200Mbps download speed service (I know, not the fastest out there, but it is enough for my needs), but the speed clocked on the wired gateway says 15Mbps. What gives?

Any help is appreciated, I’m about to return this darned thing.

TIA
