What Firmware version is currently loaded?
Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.
Lots of correctables and un-correctables that should be mostly zeros.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

hey thank you for the feedback! yeah i was really confused all these things have been happening within the last few months and i thought they got better 2 days ago seemed everything was nice and smooth but then they came back the next day and made everything worse again... and the thing is i called about it and they said they werent even there or it wasnt logged for them being there the second time.. and ofcourse it made it worse.
and everytime i call them and tell them about my logs and me seeing critical and errors they said they dont go by logs.. and say they cant see anything with my own modem.. i say well how am i supposed to get this information to you if you and resolve this problem if you dont go by logs? its very frustrating.. cause they always say my signal is too high here or something and they need to lower it.. witch makes no sense only thing i could think of is we used to have a business account with them and we also had to buy / pay for them to put internet out here for us and ever since my mom swaped it to residential i think thats when i noticed anything but even then im not sure.. i just am trying just about anything at this point.. i also asked if they could remove the splitter but we also have cable so i dont think i can?
but one thing i did notice was they have a orange coax going from the box also on my property to the closer box on my property but for some reason then put something inbetween that orange one to a black one.. then connected it to the splitter.. can i remove the black one and just connect the orange one to the splitter and fix it?

ok it seems they connected the orange one to something also with a grounder for some reason not sure if thats needed or whatever would love to just connect the orange one to the splitter but even then would rather just get rid of the splitter but mom has cable
