Connecting to my home network

​Why are random people connecting to my home network without a password and I’m running out of wifi before the end of the month. [Edited: "Language"]

There are lots of possibilities.  I'll just assume you're not running an open WiFi network that anyone can connect to without a password.  If you are, well, that's your problem.  

If the random people are not on WiFi it's could be MoCA.  If they are on WiFi suck it up and change all your keys.  Yeah, you'll have to punch the new on in on every WiFi device you have, but if someone got your key and your network is now full of randoms you don't really have a choice about that.  MoCA is ethernet over coaxial cable.  Up until the latest version it had no built-in security features, and even then IIRC they need to be enabled.  MoCA is most commonly used to connect cable boxes to the Internet.  Comcast Gateways and gateways/combo modem + WiFi router units provided by other cable carriers tend to support it.  MoCA allows then to just plug a cable box or two or three into coax and your Internet gateway will get them all online.  Cable boxes often use Internet connections for pay-per-view, on demand, etc.  The messy bit is if you have a MoCA capable gateway or combo modem+WiFi router devices on other people's home network can connect to your network.  In theory any MoCA capable gateway/combo unit install should include a MoCA PoE (point of entry) filter on the cable line to block that, but realistically linemen and installation contractors are sloppy about it and most people doing a self install have never even heard of MoCA.  Fortunately MoCA PoE filters are relatively cheap -- about $10 last I checked.  You just put one between where the cable comes in and the rest of the house.  If you don't use MoCA just sticking it between your gateway/etc. and the cable will do.

@XfinityOtto​ the same issue jus happened to me an support sent a tech out and i got a new xfi router.  two of the connections said 'hardwired' and the tech had no explanation for any of it  can you explain? i also changed the name of my wifi to ''stopusingmywifibrad'' cuz thats the name of the devices that were connecting and it doesnt show any new connections.  how else can i prevent it?  i set my wifi to not share but it was on when i just checked after the new one  was hooked up.  i'm beyond mad and xfinity support keeps wanting to upsell me stuff i don't want or need.  what do i do?

"internet-security-site-web.ho-g3.cf.comcast.net" is a private link to 10.112.21.* which is an internal/intranet IP address. Customers have no access to such an address. Attempts to access it result in browser messages like "The connection has timed out".

https://internetsecurity.xfinity.com/help/report-abuse is the site accessible to customers.

@BruceW​ I have a trace route issue, that I've seen that you also look at it.

From your response it seems that the network that I'm passing thru (this 10.112.x.x) is an internal Xfinity network (I do not know the purpose, but it seems that is going thru regardless of my configuration).

I understand that they need to internally route some traffic, but what bothers me is the delay, because if I connect my router/firewall to a cell line for example (as WAN) the response is much much faster, I loose the bandwith of course, but the connection to the websites is dramatically faster.

I would like to know if is any way to get rid of that delay introduced by these internal Xfinity networks, I cannot believe that the Xfinity trunks are much slower than the cell company.
