When I connect my computer directly to the modem using a cat 5e or cat6 cable it only connects at 100mbs. I am talking about the "link speed" (transmit/recieve) , not the upload/download speed. When I connect my computer directly to the router the link speed is 1000mbs so I know it's not the computer. I recently checked my download speed and it was only 95mbs and I am paying for 150mbs so I decided to try and figure it out and this is what I discovered. When I logon to the modem I don't have any options to reset it either. I think it might have been removed in a firmware update. Cox says I am getting the full 150mbs to the modem. Any ideas?
To reset your DOCSIS 3.0 modem, log into your Cox account. There will be an option to reset or refresh your connection.
Modems have a mini routing table so it probably doesn't like the "hot swap" connection from the router to your computer. Whenever you connect a new device, it's best to reboot the modem to renegotiate and setup a new table.
I'm not implying you'll get better bandwidth because I'm also on the 150 plan but hardly get anything over 100.
If a factory reset doesn't work, may be time for a new modem. Could be a bent pin inside the modem's ethernet port.
Curious how OP measured 95 Mbps...off the modem or the router.
I am curious what you did to resolve the problem?
