Hello I just moved into a home previous owner shut off previous isp. We transfered ours over with us. There is a giant panel with a ruckus router many wires etc and aps in select locations on the ceiling throughout home. I hooked my xfinity modem up to ethernet port and coax cable. Got internet to work on our previous network set up. However the rest of the home can not get internet. Previous owners network still exists in the downstairs as the nest was hooked up to it. Any help would be great.
