Starting several weeks ago, our service would start going out for a minute or so - when this happens our SB8200 would simply show it's dropped its connection and renegotiate - and things would come back online in a minute or so. At first we just thought it was just a random and would go away. However, last Sunday it kept doing this over and over so I opened a ticket to have a technician visit on Wednesday.
In the meantime, I did find that removing the splitter on the side of the house improved the signal levels so the modem become somewhat stable again. On Monday and Tuesday it dropped maybe once or twice though. The tech concurred that removing the splitter was the right thing to do and he did some work out at the pedestal to clean up the signal a bit more.
Unfortunately the work he did isn't enough as I'm still finding the modem dropping off randomly once or twice a day. After its been online for a while I'm seeing a trend where uncorrectables surpass correctables by 3x or more. The stats below are just after the reset that just occurred so it doesn't show that here.
Any ideas? MediacomChad, can you all see anything at the headend? It always seems that once per year we have a lot of problems pop up with our Mediacom service. It seems that I'm the last house on a line, so the signal levels have never been great and if anything changes upstream it gets unstable.
