COX Panoramic router suddenly has weak wifi signal
So i have had my router for a few months now and since the beginning of this week my WIFI signal has suddenly become weaker. I have a new TV at the other end of the house, I was able to watch all streaming apps with no issue. Now suddenly the signal is too weak for the TV to work. I have also noticed this on other devices such as phones etc that are brought into that area. NOTHING has changed at all. I tried resetting everything to no avail. I tried to get the PODS but I have the newest panoramic router (can't remeber what code version but it ends in an 8) and according to the COX sales dept, they are not compatable with yet and will be available at some time in the future indefinately SMH, so that is not an option. Also,I cannot move the router from its location because it has a few physical connections to some devices in my office. Besides, this wasn't a problem until recently but its rapidly becoming a huge aggravation. The actual hardwired connections and speed is great but the WIFI has proven itself to be spotty at best.
So before I disable the wifi and use APs or put this thing in bridge mode and get some better stuff, or get rid of it all together, is there something else I can try that I may have overlooked to fix this other than downgrade the router and buy pods?, etc. The functionality is very limited as I cannot adjust channels or power and have to use both the IP address access and app access to get anything done. I have worked in the IT Field for 20+ years and have a very strong background in networking and at this point, there is nothing different about the house that would impede the WIFI signal other than the range (which wasnt a problem a week ago) I have tried all the obivious:
--reset the router on the app and off the ap
--repositioned the router as much as possible
--reset the TV, and internet connections multiple times
--looking at the logs there is nothing significant that stands out
--TV will pull the 5GHZ signal and 2.4 GHZ signal, 5 GHZ is too weak to work and while the 2.4 GHZ signal is stronger it still doesnt connect.
--would turning off the WIFI 6 radio have any effect what-so-ever? as I doubt any devices on my network are using that
