Slow download speed shortly after modem restart

[Camreckem]

I've been having issues with slow download speed on my home network. Initially I thought it was an issue with my ISP's modem/router combo. My speeds would slow to 30mb down from my advertised 500mb down. I would only get 500mb down after restarting my modem/router. I ended up buying a CM2000 modem and a RS200 router but my issue persists. I only get around 500mb down shortly after rebooting the modem. I have replaced the coaxial cable the goes to the modem, that did not change the issue. The following is my cable diagnostic log. 

Is this more than likely a cabling issue to my residence that will require my ISP's attention or is there anything else I  can do to remedy this issue?

Cable Diagnostic

Status: Poor

Action:
[Partial Service]
If the Partial Service mode does not go away within a few hours (Click the Refresh button after each step):
1) Make sure the coaxial cable is tightly connected.
2) Remove any unnecessary splitters.
3) Replace any required ones.
4) Contact your service provider for troubleshooting help.

CM Status: Good

Downstream Status: Poor

Partial Service: Poor
Cable modem is in partial service mode. Your service provider might be under maintenance. Most of the time it won't affect your traffic and will automatically clear when work is complete.

What speeds UP and Down are you expecting to see? 

Ethernet speed testing at the modem then behind the RS router? 

Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.
Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended. 

[Camreckem]

Expected is 500 down 50 up, actual is ~30 down 50 up. I get 500 down right after rebooting the modem, then 5mins-1hr later it drops to 30 down. Speeds were taken from a laptop plugged directly into the modem with the cat5e cable that came with the modem. Speeds are the same when performed on wifi (within margin of error)

I have an ISP tech coming out Monday, so hopefully that will shed some light on the issue if not resolve it.

[FURRYe38]

If that is happening with the direct connection to the modem, then the ISP will need to check everything. Have them review the connections status page and event logs data.
