CBR-T gateway losing wifi connection
Recently upgraded residential cable internet to business internet. Being "Mechanically Inclined" my entire life from legos to cars/trucks to 4million btu/hour boilers; I knew there would be a transition period needed to work out settings, signals and possibly wiring. I switched to business internet as my wife works from home. The business internet offers a "backup connection" to stay online if there is an interruption in service.(LOL "if") My wife is not. Long story short. Since day one she has been experiencing random "wireless(wifi)" disconnects mainly on work laptop programs (having to reboot laptop and log in to applications/vpn/voip app etc..(5-minute process) Not cool for an online "chat" representative. She is losing "conversations" / "critical information" for her job process,ie. needs to be entered into associates' calendars/databases. The "disconnects" are averaging about 2-5 minutes in duration and 2-3 times daily. I unfortunately am not an "IT" guy but have done some digging/reading/digging/reading and noticed the "disconnects" are occurring at same time as IPv6 input/forward drop attempts being logged in the gateway's (10.1.10.1 admin) user interface screen. 9/2/2020 Contacted customer service- disabled IPv6 on his "program" which disabled it on the admin user interface screen-I double-checked(skeptical I guess). 5 minutes later, every wifi device in my home lost internet connection. Contacted customer service again, enabled IPv6. reset gateway. My request/inquiry or whatever was being escalated and I would be contacted by advanced diagnostic team. 9/3/2020 2am/3am/4am Home alarm keypad batteries dying causing chimes and voice prompts(imagine the pesky smoke alarm middle of the night low battery situation)no problem fix that. Decide to check settings on admin screen. Noticed IPv4 was now disabled with the "Disable Firewall for True Static IP Subnet Only" box checked and IPv6 has "Typical Security" box checked. Everything was smooth running all day until about 5pm this evening, wife experienced all to common "disconnect." Looking at the "wifi signal strength"(wife's laptop has the strongest number at -70 dBm tonight/ -71dBm yesterday. "Weakest" device currently is at -48dBm possibly a tablet or tv. I did some research on signal to noise ratio numbers, power levels downstream(-1.8 to 0.9dbmv and upstream 50.5 to 52.8dBmv). I need some help figuring this problem out.
