Hmmm. They must have changed the mapping of the URL. This one works;

Do you know the speed specs for this cable modem/router?

 

Comcast rates the DPC3941T for a max of 700.

 

or perhaps, should I replace the entire cable modem with this https://nbvstore.com/products/motorola-mt7711-24x8-cable-modem-router-with-two-phone-ports-docsis-3-0-modem?variant=32268492406924?

 

I would ! And save the monthly rental fee, among many other advantages !!

 

Thanks again for you help

 

Quite welcome !

FWIW, that's not a "protocol". It's a specification

 

"can I simply use one of the ethernet wired plugs and connect it to an external WiFi router to bump my speeds?

 

 If you are hang a stand-alone / separate router off of the gateway device, and the gateway is not in *bridge mode*, you are cascading 2 routing devices which results in an undesirable "double NAT" condition on your home network.

Google "double NAT" for info about it's potential pitfalls.

You should put it in to bridge mode in order to use a separate / sidecar router with it. Here's how;

Can't see your pic. Since you are a new poster, it needs to be approved by a Forum Admin. That could take some time. In the interim, you could try hosting it at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to it here.

No worries, the photo was just the label on the bottom of the modem/router.

Thanks for the details, I am slowly piecing this together in my brain.

Do you know the speed specs for this cable modem/router? I think I found that someone mentioned the wifi router is rated as N600, does that make sense? If so, does it makes sense to add a side-car router or perhaps, should I replace the entire cable modem with this https://nbvstore.com/products/motorola-mt7711-24x8-cable-modem-router-with-two-phone-ports-docsis-3-0-modem?variant=32268492406924?
