C7000-100NAS randomly drops internet connection

So I've read most of the post on here because I was having the come problem as most of you. (Dropped service). I tried just about everything from changing dns settings to coming coaxial cables to troubleshooting with tech support to no avail. Finally I decided to go to my local Comcast and get a Comcast modem. Talked to the customer service representative for about 10mins and I discovered a few things with my specific problem. So he advised me to try and running the line from the pole directly to my modem (c7000). As I did what he suggested.......it worked!!! But that's not where my modem normally resides. So I went to Best buy and bought 25ft worth of coaxial cable and got to work. To make this story shorter..... My internet is back up and running again with normal speeds. What I think happened: when my internet was installed they used 2 splitters on the internet line. I moved the modem upstairs and I needed more line but didn't have long enough line. So I used more splitters without realizing they already had a few on that specific line. At first I didn't have any dropped signals then a month later everything went crazy. So I took all the splitters off and ran a direct line from pole to the modem. I reset my modem and then had Comcast resend a signal and now I don't have any more problems whatsoever. Like I said this is my personal experience but hopefully someone will benefit from my experience.
