Gulf Coast: Possible Signal Issues?
I'm located in Pensacola, FL. I have a Netgear CM1000 (It was the only modem we could get working with Cox after trying various Arris models) which has been rock solid. No Packet Loss.... However, an issue we've always had is we've never had consistent speeds and we have Gigablast. I recently purchased two new laptops and noticed while downloading software to them that the speeds were much slower than normal and during the download, I was unable to use YouTube, Netflix, etc on other devices (which are all hard wired) which normally I can do without an issue while downloading, so I performed some troubleshooting (factory resetting router, bypassing router, factory resetting modem at 192.168.100.1, checking cable connections, etc) and noticed I couldn't get anything faster than 175 Mbps for download whereas I've had as high as 945 Mbps before. I took a look at my model signal levels compared to 2 months ago and noticed that they have changed drastically.
Screenshots are posted below to previous and current. Not sure what may have happened? The only thing that changed was roughly 2 months ago we tried to upgrade our cable service to some type of "Cloud DVR/IPTV" service Cox offers now (using the Panoramic Modem I assume as I was required to switch to it) and after 6+ hours of troubleshooting, we gave up and simply reverted back to our own modem and old cox equipment (Cisco Digital Cable Boxes) which all worked flawlessly. This was done as a self install so nothing changed other than swapping equipment.

Any suggestions?
