What is the brand name and model number of the router you are connecting to?
In the configuration of your modem, do you have link aggregation enabled? If yes, it should not be.
You are getting to the point where you will need to post cable connection page and event log information from your modem.
It is helpful to copy and paste information from your configuration interface to a word processing program. Adjust the margins and font size so it is readable and save to a pdf for attaching to your reply.
