Hello. We recently set up a deco M4R network at home. It was working fine for around a week or so, but now for the past few days the wifi on the Deco network has been terrible. It clocks at speeds of 2-15mbps (based on the deco app and on speedtest.net) only whereas our regular wifi that comes with the modem our ISP gave us still clocks at  our usual 150-300mbps. The ethernet cable connection (modem ->mesh->computer)still gives around 500mbps. It seems the only issue is the wifi on the Mesh network. I have tried restarting the modem and the deco but the problem persists. When i try to reboot the deco on the app, it says 'we couldn't find deco. something went wrong with the cloud service. please try again'. I've tried rebooting through the app when connected to the mesh network and also while connected to our other wifi network.

Any idea why this is happening and how to fix it?
