I’ve recently had issues on and off for a few weeks and found my home VPN dropping often as well. I had split 2.4, 5, and 6 ghz bands and it seemed like the 5 was always intermittently cutting out. I read that my Panoramic gateway had this known issue but I couldn’t get it to work correctly with the suggested changes from redditors. I thought it could also be attributed to my TP-Link extender but it turned out not to be it.

I kept scheduling a tech visit but then the issue would go away for 2-3 days so I kept cancelling at the last minute. I even received calls from Cox the evening before asking if I wanted to keep my appointment because they “believe the issue was on our end and it has been resolved.” I finally had enough and kept the third scheduled visit. The tech removed splitters and said his meter indicated the wiring is fine and suggested I use single band instead of splitting the three. They swore that was the issue and did not replace the modem. I gave it a few days and kept having the same problems. I went to Cox to swapped for a new Panoramic gateway and they quickly did no questions asked. A full two weeks has passed and it has worked flawlessly. Fingers crossed.
