Is my MB8600 the problem?
I have been having internet connection issues. I have blinking blue up and down arrows on my modem.
It has led to me having inconsistent connection and speeds. My upload speed is routinely <0.09mbps and my download speed ranges from 120mbps to 670mbps hardwired.
I have reached out to the ISP and they claim there is no degradation on their end. I have done a factory restart, I have tried a different router, I have changed the coax cable behind the plate, I have tried different ethernet cables, I have done a factory reset on my router as well. I have changed the cable splitter to flow directly to the modem instead of being split.
I am having the hardest time troubleshooting. I have no idea where to go from here other than trying to have the cable rewired from outdoors.

Most of the stats are out of spec.
That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.
In an effort to try to obtain better connectivity / more wiggle room, check to see if there are any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1002 MHz, bi-directional, and no gold colored garbage from Home Depot, Target, Wal-Mart, etc. Splitters should be swapped with known to be good / new ones to test.
Also check the coax cable for any damage such as cuts, nicks, abrasions, kinks, sharp bends, etc.
If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two-way splitter connected directly off of the drop from the street / pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.
Good luck with it !
