C6300 Upstream light flashing

Question

So I recently moved my modem upstairs which required me to rewire/reroute some coax cables. The first day it worked just fine, I moved it to my room for faster download speeds on my pc which is connected through Ethernet. Earlier today however it kept having issues and eventually the internet just completely turned off which eventually led to me moving it back downstairs where is works perfectly fine. I believe it’s a problem with the coax cables but I’m not positive. There’s one coax outlet that works which is what the modem is connected to now, but before when it was upstairs I had basically just run a line of coax cables from that outlet to upstairs, but it doesn’t work anymore.

TL;DR - modem has no internet connection, one working coax outlet. Modem works when directly connected to said coax outlet but not when connected to the outlet through a line of coax cables. Please help

do you have a screen snip of the cable connections page when its hooked up for both locations? that lets us take a look at the signal. It wouldn't be the first time wiring within a home had issues.&nbsp;

So this is the screen snip for my cable connection screen when it is plugged in downstairs, however I can't even get a screen snip of the page when its upstairs because it claims my modem is offfline, so this screen doesn't show up in the first place.

my bad, new to all of this. I've never needed to come here until now

so in the location that it works, your powerlevels are a bit boarderline. The upstream shouldn't be much higher than what it is and the downstream should all be within 3.5dbmv of each other and you're right around that. adding distance to the line probably pushes you over&nbsp; limit.&nbsp;
