u/Express_Echo_8029

Hello! Would greatly appreciate some ideas/suggestions here. I'm getting 900Mbps on my PC, which is wired to my main Eero Pro 6 router. But on Wifi, as well as every other Eero router that is hard-wired to the main Eero, I only get approx 80Mbps.

I have connected via Wifi to the main Eero router and only get 80Mbps. I have even turned off Cellular on my phone to confirm I'm only on wifi.

One idea is the outgoing ethernet wire from my main Eero router (which feed the rest) may have a bad connection, could that be affecting it? But then why is my Wifi on this main router also only 80.

Anyway, would love some help! thank you,
