I've been running 3 x Eero 6+ on my home network. Connection lately has been terrible but I noticed it seem to be mainly on my home PC and work laptop. Phone and TV seem unaffected. For example it will suddenly drop on my PC, I will run Speedtest on my PC and phone which are on same desk, PC will show weak signal, phone full even though both connected to same Eero via same wifi. Any suggestions on what I can look at to fix this please?
