Under 500mbps on Gig plan

Modem levels are good, wired and wireless through the Asus ac86u has never been over 500mbps, normally tests in the 350-400's. Wiring directly to Netgear cm1000 modem produces the same results. Less than 50ft run of buried orange coax to grounding block, ~30ft of rg6 to 6db fpa connected directly to modem(no splitter so hot signal). Same speeds without the 6db fpa, but connection drops and lots of uncorrectables without it.
I had the gig approved xfinity modem, with which I experienced the same speeds.
Any advice?

Re: <500mbps on Gig plan

Thank you, I should have mentioned it in my first comment but I've already searched the forums and gone through the troubleshooting process listed at the link you posted. I'm hoping someone from Comcast can check my connection/area.

Re: Under 500mbps on Gig plan

Start with posting those good levels. Have you checked your speed straight at the modem at the ground block before any interior wiring?

Re: Under 500mbps on Gig plan

Corrected: I have not tested at the grounding block as its a straight run of rg6 from the block to the modem, but I will check when I get back. I don't have access to the modem as I'm traveling but I have lurked these forums for a while now and the numbers are all in spec. Additionally, upload speeds are always 40mbps+. I will post on Wed when I have access again. I'm hopeful someone can check for issues in my area that could be keeping me from reaching full gigabit.

@CCAndrew Here are the connection stats. I have yet to test the connection outside, the weather has been quite bad, although I don't know that it's even worth testing given the levels below.
