Nighthawk C7800 drops connection, has DOS Attacks, and 8/32 locked channels.
Attaached are my logs. Additional information includes that I indeed have a cable splitter in my box, but it connects it to only to the direct cable. Sooooo there is no need for the splitter. Does th...
remove any splitters, amplifiers, or signal attenuators from you coax line.
Check the link for kinks, damage, loose/old/bad/cheap connectors and replace them if you do.
Move the modem to right where the coax comes into the home and direct connect it.
If after doing that the logs/connections still look the same, the ISP needs to check the line.
Plemans,
I've crawled under the house and made sure the coax was intact and not damaged or freyed in any way.
ISP just reported to me that they have no issues with my connection on their end.
The ISP said to leave the splitter, even though it's not splitting anything, because my power levels are fine where they are.
Note:
-I bought this cable modem new in September 2021.
-Every morning I have to unplug and plug back in my cable modem about 10 times to get it to broadcast internet. Stays on for about 5 minutes then kicks off, but eventually sticks. I don't know if it is confirmation bias, but it seems like I lose interet during freezing temperatures.
-I performed a factory reset and my DHCP lease time went from 24 hours to 1 hour. (Personally spoke with ISP and they said they don't have control over that).
I'll have a line tech come out if it isn't resolved this week and the logs look the same.
The reason to remove the splitter is because they can go bad and cause interference on your line.
You're currently not locking the channels you should and you logs indicate a line issue connecting back to the ISP.
So I'd take out anything in the line that could be causing issues.
Plemans, I've removed the splitter, and it has effected the power levels in the following way:
This is post splitter removal:
Power levels are a bit high but they're at least locking all the channels.
I'd be betting on a sketchy splitter.
Is it running better?
