ARRIS Surfboard DOCSIS 3.1 Gigabit Cable Modem and AX3000 Wi-Fi 6 Router, Approved for Cox, Spectrum, Xfinity and Others, Wireless Technology - New Condition

I have been using the arris/motorala surfboard modems for a long time. My cable provider - Shental - which recentely went to another platform that combined cable with streamining videos that advertised no cables.needed for any smart tv capable of downloading their interface and rely on 100% wireless connectivety back to modem/router but had to run on docis 3.1. So i had to upgrade router to docis 3.1 from 3.0 per their requirements. It has been a very unpleasnat experience thus far with running two boxes which only provide a cable interface which i have to have for an ederley mother which has severe vision issues and does ok switching between channels but wouldn't be capable of understanding or capable of switching between streaming services. We operate two boxes provided by cable provider which connect wirelessly, one cell phone and a laptop or tablet occasionally on a 100mps plan that consistently drops the signal on all of the devices with cell phone experiencing the least of the connected devices. This router suggested an app to configure router - like simply changing wifi ssid and cooresponding passwords, setting up guest accts,etc. which i have set up my own networks for years on both personal and business settings. I found the process very tedious at best and after attempting multiple times to install a linksys mesh system to expand coverage for better overall coverage couldnt get the linksys velop which i had used for several years with old router to connect. Reset system and just left factory ssid and passwords and still have dropped signals to their wireless boxes with one only located 30 ft from this arris g34 unit with no walls or other objects in direct line of site. Considering the technolgy, advertised coverage of the arris g34 unit and several different devices that all experience similar connectivity problems they all point to the G34 unit and after reseaching reveiws this seems to be a common problem.
