Recently I have been experiencing up to a 50% drop in my internet speed (Vivid 100). Also I have been losing access to the internet frequently, these loses in internet sometimes only last for a few minutes but have lasted as long as 13 hours(This was on Christmas day). When accessing the router settings it says Access Denied next to the Internet icon while the internet is down and will persist even with a reboot of the router. I have a super hub 3 and I did speed tests on a desktop that is directly connected via Ethernet to the router.
Check all your coax connections are in nice and "finger" tight at the Hub and wall box and at any splitters/attenuators/etc and that the internal wiring is ok with no kinking or chaffing (rabbit chews!). Also check that all looks good with the outside cabling and wall box.
If that’s all good.... post up your Hub/network connection details and someone will check to see if there is a problem there. In your browser’s URL box type in http://192.168.0.1 (or http://192.168.100.1 - if in modem mode) and hit return. On the first page up [there should be no need to login if you have done so before] click on the “router status” text at bottom middle of first page up and then copy/paste 3 sets of data onto here - the downstream, upstream, & network logs. Don't worry about the formatting it can be easily read, but try to avoid using screen shots & don’t include personal data or mac addresses - blank them out.

Thanks for the reply. I checked all the cables and they are all fine. Just to be sure I unplugged and plugged them all back in. I will post up and downstreams when my Internet comes back on as right after I sent that reply it went down.
