Modem replaced

Last Thursday, Friday we upgraded equipment to connect with the world.  I moved the new modem into our cold basement.  That means I must sit in the cold if I want to hard wire into the modem.  Wireless speed throughout the house is also good.  Yesterday morning I spent an hour understanding the Android/windows methods to cast my laptop screen to our chrome device hanging on the big TV.
All this radio energy zooming everywhere is a blessing and has a down side.
