Internet Network Connection drops every two seconds. New modem installed by technician in March 2020 and since then the trouble started! Numerous calls to Xfinity and still the same. Noticed that Xfinity Wifi hotspot was also installed, unbeknown to me, overpowers my home network and keeps disconnecting my home network with a message "connected no internet" or disabled!
