here's the log as requested and I managed to get video of what I meant by when it's lagging.

Link is dead for me. And I think those logs will hold the key.

Video is very interesting. That would have been impossible to explain otherwise, thank you very much. First thing I noticed, IP did not change between release and renewal and IP is a public. Second, the first speed test seemed to take a abnormal time selecting the correct server, but then show low latency to that server. Third, this is a rather specific problem that I have found evidence happening using different modems, routers and computers, and only commonality was ISP.
See post here. 4th, when I called
VyveBB there was literally an announcement every 3 seconds that they are
having problems in OK area. Question: What is data at 1m14s?
Hypothesis: Severe routing problems at the ISP level that either by fluke happened at same time as firmware upgrade, or firmware upgrade changed way router talks to modem (gateway) in some way. Maybe releasing and renewing resets the routing table they have for the MAC of your gateway in the CMTS, but they would have to be using some funky code. Have your tried setting your IP to static? Just use all the same settings as DHCP gives you. If this doesn't fix the problem, then you know for SURE it's ISP side.
Update: Did this problem start 3/31 to 4/1? If so, could be related to the Cox Analog/Digital transition that took place on during that time in OK and caused some problems. Maybe the connections between Cox and your ISP changed? Not that it matters, but more evidence issue is on ISP side.
