Hello, 

I've set-up my home wifi with an Archer MR200 modem and a Mesh device RE300. It's been working perfectly for the past week but today I started experiencing much lower speeds and stability - 86.877KB/S in upload and then 26.883KB/S in download. 

What's surprising to me is that the SIM card strength is at 100%, and I can see a full wireless signal in all my devices. Issue persists even through an ethernet cable. I have 15 devices connected to the wifi, and the connection started getting particularly unstable during Zoom calls today. 

I've been reading a few articles and I see references to the channel and width. Unfortunately, it doesn't look like this is something that I manually change so I'm looking for help with troubleshooting options. 

Best, 

Margherita
