CM1200 slows down after 24-48 hours of uptime when using link aggregation

I have used Netgear for all of my networking needs at home and in my business for more years than I can remember and never had any issues until I got into the CM1200 and RAX80. I went back and forth with tech support to no avail. One suggestion that worked for a while from my losing internet connection on slave devices was to set the DNS to 8.8.8.8/8.8.4.4 on the CM1200. I never could get port aggregation to function for more than 8 hours when the speeds would drop to 26MHZ. Then the 5G radio in the RAX80 started dropping out for reasons unknown, but by that time I was out of warranty and support window. If I ran a diagnostic the 5G would come back, but never stays reliable. I put AX transmitters on all of my computers, hoping that would help and it did greatly help exchange speed, but never solved the 5G problem. I am now running into devices losing contact with the internet on an individual basis randomly. I also noticed that if I had a laptop 6 ft away from the RAX80 the signal quality never got much above 50. But even now wired devices are again losing access to the internet although the internet light on the RAX80 shows connected. This has been the most aggrevating and frustrating journey I think that I have ever experienced with computers. I think NETGEAR is just not the same company with which I had become so reliant over the years and I can no longer trust their equipment and their techs are clueless now as to how to help in crisis. I depend on my computers having reliable access to the internet for my livelyhood and do not have time for this NETGEAR tech dance, so I am researching to find a more reliable setup and say bye bye to what had been a great partner in my computer work over many years. So any suggestions would be appreciated as NETGEAR is all that I have ever used.
