Arris SB8200 Firmware Update / Download Speed Issue
Hello - I activated a new SB8200 today with Cox.
In reviewing the firmware, it appears that the modem does not have the latest firmware update applied. That said, I also understand that Cox controls which firmware is actually applied to the device once it is on their network. So, I'm looking for the answer to a couple of quesitons:
- What the the latest approved firmware version for the Arris SB8200 modem on Cox's network? Mine is running AB01.01.009.27_081619_183.0A.NSH
- If a more recent firmware has been approved, how long does my modem have to be online before it will pick up the latest firmware and apply it?
I bought this new modem (along with a brand new TP-Link AX6000 router) in an attempt to improve my download speed. However, I'm finding that the speed is not improved any from the previous setup (which was the Cox-provided Panoramic WiFi modem). I am a Gigablast customer and this modem is listed as "Gigablast compatible". I'm getting around 200-300Mbps down on average.
In reviewing the modem's event log, I also notice several "SYNC Timing Synchronization failure - Loss of Sync" messages. Not sure if that's relevant or not to this issue.

I'm also not sure what normal signal levels are for the service/modem, so hard to know if these are within range or not:

I realize that there's no guarantee as to speeds, but I've literally never gotten anywhere close to "Gigablast" speeds. That said, I'd be happy to consistently get between 500-700 down. Am I crazy to have those types of expectations considering what I pay for this service?
Thanks in advance for all the help!
