Panoramic Gateway Bridge Mode

My Panoramic Gateway is hooked up in my office so that I may have direct connection to modem for business.  However, this makes WIFI in our house spotty at best and our devices, televisions, laptops etc. were all dropping WIFI.  So, I put the Panoramic Gateway in Bridge Mode and hooked up my own Linksys Velop Router/Mesh system.  This solves the WIFI connectivity problem 100%.  However, at the same time, now our cable television is no longer working......... So I am paying for cable and internet, but can only have one at a time.....  Any help would be much appreciated.  Thanks in advance.
