Description: The article is about centurylink login. The author shows how to use CenturyLink Fiber with Asus RT-AC3100 without using Centurylink’s Modem. He also shows how to eliminate the CenturyLink’s Router altogether.
Do you have CenturyLink fiber service? Do you want to use your own router with CenturyLink fiber? This article can be useful for you. I am a longtime Comcast user,I recently switched from Comcast to CenturyLink fiber because they had a very lucrative offer for me,they had a gigabyte service in my area and I couldn’t pass the offer,so I switched to CenturyLink.
After switching the service,I realized that my powerful Asus Rd AC 3100 router was not useful with the Century Link service,let me show you the current architecture. The problem is that CenturyLink has their own modem router and combination that CenturyLink provides,this is this particular device.
Even though CenturyLink calls this equipment as modem,it is not a modem,it acts as a router. We will see how to eliminate the need of this particular modem which CenturyLink calls as modem. It’s not a modem,we will see how to eliminate the need of this modem altogether and how to have a direct connection from your router to CenturyLink.
First,you need to understand that,let’s see why we are here. You also have CenturyLink fiber-to-the-home service,maybe you have tried utilizing your own router with central links modem router by taking a cable out of central links modem router combination and putting it into the van port of your router.
When you do that,you will run into the situation of double NAT,that means your router is at the CenturyLink level. The Technicolor router does its own local networking and it assigns private LAN IP addresses. One of these private LAN IP addresses is assigned to this particular router that you have. I have AC 3100. In my case,this router comes with a private LAN IP address to the computers or other devices.
There is a double NAT going on,you have one level of NAT at this level and second level of NAT at the equipment or the router provided by CenturyLink,this is not a good network configuration because if you want to use dynamic DNS at your router,you cannot do that because you need to have a direct connection to internet,you cannot be in the double NAT situation for it.
If you do not like paying the monthly rental fee for the CenturyLink modems router,that can be a good case,you can avoid paying the monthly rental fee or buying the modem router altogether from CenturyLink which costs about 100 bucks. I also talked about high-level basics of VLAN. One more option that some people tried was a bridged mod. When I went online to search for how to avoid a double NAT situation,I read an article about that.
It showed how to put your CenturyLink modem again. Every time I say modem,I want to bang my head against the wall because it is not modem. Whenever I say modem,it is the sensory links terminology that I’m following,they want to call it modem so I’m going to call it modem,but you need to understand that it’s not a modem.
When you try to put your CenturyLink modems into the bridged mode,it doesn’t work and it doesn’t work even though you have the PPO username and password from CenturyLink,you have tried to put that password in your router and you have made the CenturyLink modem,you have put it into the bridged mode,it still doesn’t work,we will see why it doesn’t work and how to overcome this issue.
The truth about the CenturyLink modem is that it is not a modem. When essential link technician comes,he installs two pieces of hardware,one piece is the Ont which is optical network terminal and the second one is a central link modem,in my case it is Technicolor C 2100 T modem.
What CenturyLink refers to as a modem is a router for the fiber customers. This is not a modem for DSL customers but for fiber customers,it does not act as a modem,it is a simple plain router. I think CenturyLink has intentionally tried to make things hard for the customers so that customers will use their hardware and in turn they will pay them a monthly fee or they will buy the hardware for them.
This is my perception,I could not see any other reason why they not let me know about this. Every time I call the technical support,they do not want to tell me how I can use my own Asus router by bypassing their own hardware,so at a very high level I want to give you the concept of virtual LAN. Before doing that,let’s see what LAN is.
There is a switch where you can connect your individual computers to,there are seven computers connected to the switch and they all can communicate with each other in the regular land mode without the concept of virtual LAN. Now if we put the modem or if we put the concept of virtual LAN over here,we would add two virtual LANs in this configuration,let’s see what will happen if we add two virtual LANs.
Devices 1 2 3 are in virtual LAN1 whereas 4 5 6 7 are in virtual LAN2. That means there is a logical segregation that has been done. The broadcast messages can only be received by devices 1 2 3 because they are in a segregated virtual LAN area. When devices 4 5 6 7 broadcast any message,those messages will stay in 4 5 6 7 devices.
We have achieved an actual isolation of these two LANs without having a separate Hardware,by using the same hardware,we are able to segregate these two sections of devices all together,this all happened from the 802.1q which is the industry standard for virtual LANs.
The network traffic receives virtual LAN assignment through something called tagging,the concept of tagging came forward from the header of the layer 2 frame .
The header receives a specific tag or the virtual LAN ID,this virtual LAN ID represents which virtual LAN the tag traffic belongs to. In general,most default routers or switches use virtual LAN, they communicate the network devices and protocols. They are on the same virtual LAN and they do not need to be configured for separate VLANs.
In today’s network layer 2 network devices,they support 802.1q architecture for traffic tagging where the host packets receive virtual LAN assignments. VLAN 1 and VLAN 2 are tagged respectively with their own virtual LAN IDs,they have a segregation,they cannot communicate with each other because they have been tagged with their own words to LAN IDs.
Why are we even talking about this? The reason we are talking about this is architecture. CenturyLink tags all the traffic going from the central links modem router to the CenturyLink Ont,it tags all the packets with 201 virtual LAN ID. If any other packet going from a router or from any other device goes to CenturyLink Ont without 201 tag,due to segregation at the virtual layer,the packets won’t be received in the right network.
All the packets needed to be tagged with 201 tagging,you can put the CenturyLink modem in the bridged mode,you can do the authentication at the router level because the network traffic is not tagged at 201 VLAN ID.
Centurylink Ont will not know what you are trying to do and that’s the reason why the bridged mode does not work. In our case what we want to do is to completely eliminate the need of the CenturyLink modems,let me go to the next slide.
We want to do the pppoe authentication and 201 tagging,we want to do both of these things at the Asus router or whichever outer you have. We want to send the packets to CenturyLink Ont. In order for us to do that,let me show you what configuration settings would be needed.
You need to go to the IP address of your router,in my case it is 192 168 1.1 or you can even type router.aces.com,that takes you to your own administration page. You need to log in with your admin credentials obviously,you will need to go to advanced settings and click on LAN and then click on IPTV.
In this LAN IPTV,you have to select the ISP profile as manual and you have to put the Internet as 201,the VID has to be 201. By doing this,you are able to achieve tagging the network traffic as 201. The second step that needs to be done is pppoe authentication. You will need to go to the VAN setting in the Advanced Settings and in the internet connection option,you’ll have to enable the connection type as pppoe,you have to provide your username.
The red quest.net was the domain that I was having. You need to provide your password. The second screenshot is the bottom of this page,you can scroll down and click apply. After you have done this,all you’ll need to do is to take the cable out from the CenturyLink modem and plug it in into the VAN IP hole of your router.
You can reboot the router and your router will be connected to centurylinks. It is a very simple thing to do,you understand that a pppoe authentication is not what you need,you need to do both pppoe authentication and 201 tagging. As long as you understand this concept,it is so easy to do.
