Bluetooth Disconnect - Logitech Anywhere MX2s

M1 iMac
Anyone else experience bluetooth disconnects? It seems okay with Apple mouse, (Hate using this mouse) My Logitech Anywhere MX2s disconnects. Can't always reproduce, but need to use Apple Mouse to reboot. After reboot the mouse still didn't respond until Parallels Launched and Windows logged in. Been having problems with Air Pods Pro and the new iMac. I found that Wifi Router behind the iMac is fault, but sitting in the same chair, iPhone to AirPods are fine. Could be location of Router, but it seems these two are not related. M1 Bluetooth seems to have issues. Any ideas?
