Can ISPs block one device (my PC) from the internet?

PenguinLover · 9 Jun 2017 at 20:16

I am currently on Virgin Media and would like to know if they can block one device from the internet without any others being disconnected.

Maybe if they manage the router and the router supports it.

How do I find this out, and would they ban this for watching porn?

Lol, no and no. In theory they could likely get into your router and perhaps blacklist a MAC address, but it's not something they would do for "watching porn" (or at all).

Change your MAC address on your network card. If the internet magically starts working again, then its possible, but also just as likely to be an ARP Cache issue.

Have you restarted the router at all since the problem began?

Haha thanks, it's just that the internet went dodgy a day after I watched porn on my computer for the first time, thus leading me to believe that's why my internet was not working. And I have tried practically everything, router restart, command prompts, change of Ethernet cable etc. But has not tried to change MAC address. Are you sure they can't ban 1 device from the internet (btw I'm panicking so I want to be thorough lol)

Like I said, in theory they "could" blacklist a MAC address on your local router, but not from "the internet", as all of your devices will be presenting themselves to "the internet" as the WAN interface's MAC address of the router (this is how NAT/PAT works). The two ways to prove or disprove that your MAC address have been "banned" (blacklisted, blackholed, added to an access-list, etc) would be to change your MAC address, or change your router (stick it in modem mode and use another router behind it for example). You could also "double NAT" behind another router without switching to modem mode.

Like I said before, I'd find it highly unlikely that Virgin Media would go to the trouble (and potential risk) of using a back door into your router, just to stop you watching (I presume legal) videos?

Haha yeah buddy, obviously legal I ain't a creep lol and thanks

Also how do I change the MAC address

I do like the way you glossed over everyone telling you that yes, in theory it could happen to simply thank the one answer you wanted to hear.

The person who told me other wise I had one last question for him and then I would thank him, but he didn't reply

Do you want help in restoring your PC's access to the internet?

If so then post the results of running the following two commands and the command prompt:

ipconfig /all

and

tracert 8.8.8.8

and we can see if anything odd sticks out.

Thank you I will try this in a few days as I don't currently have it with me.

As a veteran Virgin Media porn consumer, I've never had any problems. Even with the midgets.

If you are saying one device cannot get to the internet then it's probably your firewall that's bust to you use Norton, Mcrappie or any other PC slowing products?

No I do not
