Downstream Bonded Channel high uncorrectables

Hello I was having connection issues with my service so I replace my old modem (Netgear N900) to a Arris SB8200 so during this I learned about getting into your modem to check things out. Well I did and noticed a high number of correctables/uncorrectables on channel 123 and 124 I tried calling tech support but go pretty much nowhere and during the call my cell phone dropped the call. So figured I'd ask here on the Cox Forum and post what I'm looking and and would like to know what can be done to fix those channels. I only have one cable going into the house from outside and have replaced the wall plat and cable from wall to modem. Here are pics of the box outside I did connect the inside line to the ground block as I do not have cable or phone any help or info about whats going on would be great. Thanks

Edit: Link to pics

    You could try testing without the router and see if there is any difference. Otherwise it may be time to see about having a technician come out and take a look.
