I need to log in to the xfinity router to fix something of major concern.

 

Imagine my surprise when I discover that contrary to the rest of their crooked empire, the login to the most sensitive place where you really really don't want your security compromised, is a simple freaking http. Up. No https.

 

So, I am extremely annoyed at this. And using a VPN, as I do all the time, and especially with a stupid unsecured connection like that, they make me jump through a million hoops to prove my identity.

 

But I remember reading that you shouldn't log in to your router over WiFi anyway, but you should use an Ethernet cable. Which I have, but how do you use it? I connect the modem to my computer with the yellow ethernet cable and then what?

 

Believe it or not I ddg'ed this but it is apparently such a stupid question, along the order of "how do I know the sky is up and not down?" that nobody bothers to explain it. Nobody apparently ever asked it either.

 

Anyway, I'm asking. Seriously. How do I use an ethernet cable without WiFi being involved?

Because when I did that earlier today, everything looked the same. Nothing popped up or anything that would prompt me to put in a url or anything at all. What do I put into the browser window once the cable connects modem and computer?

 

Thanks.

Is this a combo modem/router or separate modem and router?  Make/model numbers?

It is unsurprising that the URL to any router is http: not https:.  The traffic is not leaving your LAN, so unless you've got someone on your LAN, or who's hacked your LAN, it's never making it to "the outside world" and really doesn't require encryption.  Good security starts with accurate risk assessment and guarding against the probable, not the remotely possible.

 

If you have a standard Comcast Arris modem router (as I doubt you have a separate modem and separate router) the likely address is 10.0.0.1, but look on the bottom of the device where there's usually a sticker that tells you this URL, the admin login (as shipped) and password (as shipped).  If it's even close to a recent device one, the other, or both of these will not be easy to guess.  You can generally look up the "IP URL" for virtually any of the common modem-routers for the major ISPs via a web search if you know the make and model.

 

I have never been concerned as to whether I'm logging in to a modem-router on any LAN by WiFi versus ethernet cable.  Of course, when you're initially setting everything up you generally have to use an ethernet cable, but after that . . .
