ISPs blocking users from using their DNS until they register their account. A fix!

post #1 of 5
Thread Starter 
When I signed up for my internet, the rep came and installed the modem and did a line check and then siad I was good to go. Well, I spent about a half an hour running network diagnostics trying to figure out why I could not get online. Then I realized I had to register my account before they could allow me to use their DNS service.

So, yesterday I was helping a friend setup their DSL. The tech came over and installed the modem ect. and noticed the problem and the ISP could figure it out. They wanted to send the tech back over and do more line checks. The problem is that most ISP's block users from using their DNS which is required to browse the internet until they create an account first. Tine Warner at least had the common sense to redirect me the their registration page so I could kind of figure it out. With Cavalier, there was no redirection at all or message letting the user know they have to activate their account. Which is kind of a catch-22 because you have to have the connection first before you can go online to register, before you can use it?? How on earth would anyone have known that the ISP was blocking them the DNS servers?

So I configured their connection to manually enter a DNS, which I choose Comodo's free dns service https://www.comodo.com/secure-dns/. That let them connect to the internet without having to register.

Then when I tried to connect the Wii it wouldn't connect to the internet so it took a while before I realized it was because the Wii was trying to use the ISP's dns service, so I switched it to a free DNS also by creating a custom connection with a manually entered DNS, and now everything works.

I hate ISP when they create most of the problems themselves which increases the cost of their service because of tech support costs. I realize that they don't want non-users to use their DNS service, but at least the techs SHOULD know that's what the problem is so they can fix the problem right then and there instead of raking up charges for something so stupid.

I use OpenDNS and Google's DNS as a secondary. When I had Rogers as my ISP they use to inject ads and notices into web pages. I quickly changed their DNS to OpenDNS.

Same here. I prefer 8.8.4.4 primary and 208.67.220.220 as a secondary. They shorten response times, as well.

Sounds like a lazy/crappy tech that didn't complete the enrollment process.

Comcast won't allow any external traffic until you register your account with your cable modem MAC. If you have some sort of external DNS preconfigured, you won't be able to reach it and your requests will fail. Had this happen when got service a couple months ago as DNS servers were predefined on the firewall.

For DSL you should not need any of these steps as authentication is handled by your PPPoE session.
