Hello everyone,
I am having trouble with my downstream bonded channels. I am on 500mbps speed teir, and our internet seems alittle slow. I have a Netgear C7800. I noticed that some of the downstream channels will sometimes go to unlocked and back to locked. They seem to flucutate, but have recently gotten more steady. I am in the process of buying a new 1GHZ splitter that was recommended to me by my buddie from work. Can someone check my channels to see if everything looks normal?

Also the comcast app shows my router as not connected even though I have internet! I'm wondering if I need a tech to come out.
