My ISP is Comcast/xfinity. I am using ARRIS Surfboard SB8200 DOCSIS 3.1 bridge mode. I have a MikroTik RB2011UiAS-RM Routerboard Rackmount 5xLAN 5xGbit LAN 1xSFP connected to ARRIS Surfboard SB8200 DOCSIS 3.1. Here is my issue the ARRIS Surfboard SB8200 is a Gig-e port. The RB2011UiAS will not connect to RB2011UiAS as a 1 Gig port. if I hard set the RB2011UiAS to 100 meg both units will connect, but dhcp will not work or pass traffic. Any suggestions.

Both units will connect? Makes me think you’re connecting more than 1 device to the SB8200.
The SB8200 has 2x ethernet ports. Most users believe that both can be used but sadly, most ISP’s only support 1 connected device.
So make sure you only have 1 device connected to the SB8200.
Power the modem and the router off and disconnect everything (even coax) from them.
Leave them off for around 5 minutes.
Then connect coax back to the modem and power it on.
Wait 2 minutes.
Connect lan port 1 on the modem to the Mikrotik router and power it on.
give it a couple minutes to boot and try to go through setup on it.
If you want to use both ports on the SB8200, you can setup wan port aggregation on the modem and on the router (if the router supports it) for over 1 gig speeds. But most ISP’s don’t support more than 1 device connected.
