Modem Vivo WiFi em Modo Bridge – Datacom DM2270 ADSL 2ft + 2I – Askey RTA9211W (RTL8676) 2-Port ADSL

As I commented in the article on quickly DPS Guard Against Rays p / Cabos Clamper, I subscribe to a local Internet service provider for fiber optics, which is the best option I have in my region. But I was not very pleased with the stability, then also I signed the Vivo Internet Fixed, ADSL (the old Speedy), as Vivo does not meet my region with optical fiber. So with two not very reliable providers I make a reliable connection and still have a higher added flow.

The modem I received from Vivo was the WiFi of Datacom, modelo DM2270 ADSL 2FT + 2I, plataforma Askey RTA9211W (RTL8676) 2-Port ADSL. Web interface that appears is a wizard that does not give virtually no configuration option, but coach hinted: access the modem by URL, using the user admin and the password that are 4 last digits of the MAC address of the modem. This makes it possible to make some settings, yet they are somewhat restricted, and put the modem in order bridge It was not an available option, unfortunately.

I prefer the modem in bridge mode since I already have a good router, that is ASUS RT-AC68U Dual Band Gigabit Router 802.11ac Wireless-AC1900. Leave two routers in the network and have double NAT is something that eventually brings problems, especially with online games. Even thought about using another modem, but this Datacom can achieve higher rates than the TP-Link TD-8816, what would be the alternative that I have at home.

But recently learned that gives to unlock the full potential of Datacom DM2270 ADSL 2FT + 2I and have access to more advanced settings, including the configuration bridge. The procedure is in this blog. It's for Coletek W-N2120, I used not Live Fiber, but also works perfectly in Datacom DM2270 ADSL 2FT + 2I. The idea is to directly access a URL in modem that lets you download a file with all settings (at backup), make a small change and up the settings back to the modem (restore). There is a small program that helps with this task, the Telnet2764 (Sagecom 2864 Tool). It downloads the settings, allows you to edit them and upload them again. The idea is to find your user (admin if you have not changed) the settings. A string é ‘(username(admin))’. Just below is his role '(role(home))’. Just change the role of 'home’ para ‘super’. Then just up the configuration back to the modem and ready. Next access the web interface is already complete with all options.

To set as bridge, First I disabled the PPPoE connection made by the modem itself. Just used the button “Disable” no menu “Internet connection”, submenu “Settings”, as shown in the screenshot below:

Por fim, you must enter “System”, after “Network connections”, click “Lan Bridge” and, finally, in “Bridge”. There are three marked boxes, a do switch LAN (the two LAN ports) and two connections to WiFi access point. The WAN connection is cleared ETHoA, just mark it and ready. The WAN port will already have a bridge to the LAN ports. There just connect a modem LAN port on the router and configure the PPPoE connection to the router itself.

Remember that using the modem as bridge, the modem interface is inaccessible over the network, because it is outside the router's LAN, even if your IP is in the same range. It also does not help put the IP on another track, for then the router will forward the packets to the gateway. The solution, no caso do ASUS RT-AC68U, It is to create a second IP to the WAN port of the router and put it on the LAN. One way to do this is to log into the router via SSH and type:

This configuration is with the router in the Dual WAN mode and the modem in WAN2. For other settings just change the 'VLAN3’ to the correct VLAN. This setting needs to be redone when the router is restarted. One way to automate this is to use firmware RMerlin and create a script called nat-start in /jffs/scripts with the following contents:

It is important that nat-start is executable:

For other routers may be unable to do this kind of configuration. In this case one solution is to connect the second modem's LAN port to a router LAN port. It is important in this case disable the DHCP server modem:

Interestingly, by connecting a modem's LAN port to a router LAN port, the modem has to ask an IP router. So the modem is two IPs, did ( by default) and he acquired the router. You may want to configure the router to always give the same IP for the modem in DHCP to facilitate future access. In my case I left para o modem, and now that's how I access its interface on the internal network, using a TP-Link TL-R470T v4, which now makes the router function and Load Balancer on my network, leaving ASUS RT-AC68U only as access point and switch (I will speak more of this in an upcoming article).

    There is a possibility of DM2270 as Repeater configuration?

      I don't think so.

    Skooter, Thanks for the tutorial, I was able to access various settings on my modem/router DM2270.

    I would check if u can help me with a question, please, do you know if it works use it only as a router?
    Connecting to the modem vivo Coletek W-1101?

    1. 2.1

      I don't think so. He has two doors, but they act as in a switch, I don't think it's possible to put them on separate subnets.

    Hi very good tutorial.
    I have a Modem Datacom also DM2270. I wonder if it is possible to receive the signal of the LAN1 or LAN2 port internet this modem and route the signal via wireless? Because the cable comes directly from the street to the network card of the PC as a point-to-point connection between the Web server and my house. Want to configure it to authenticate automatically on the server. It is possible to?

    1. 3.1

      OLA josue,
      Maybe if you leave the bridge between the WAN and LAN Ethernet Switch Hardware ETHoA, He can authenticates the PPPoE on LAN connection (assuming be PPPoE), and the 802.11 n Wireless LAN Access Point would be separated to act as LAN. But I don't know if this will work, just testing to see.

  4. 4

    Dude thanks for the tips…an important detail: in “network connections”, in the WAN link PPoE, configure how underlying connection “LAN bridge” and bingo…Big hug

    What is the pin number for this router friend, Maybe it's just like mine, I'm having problems with my pin number didn't come, that number of 8 digits.

    1. 5.1

      I couldn't find any PIN number and any number of 8 digits. What good is this number?

    Olá Friend,

    First congratulations for the post, I'm racking my brain trying to solve here may be more simple than I imagine, I want to put a TP-Link 741 as WDS, However no sails, ruled out IP error and the modem this is just with this modem that he's not running my DSL alias equal to its, I saw on another forum how to unlock now to researching how to configure, If you can help agraço. Thank you.

    Congratulations on the tutorial! I would like to know if there are any native or external tool to reset the modem automatically (Just to change the IP). I tried that but I couldn't Scheduler. Thank you.

    1. 7.1

      As he accepts SSH connections, You can configure any external tool to connect and run a script. But I don't know any to indicate.

    Good evening friend,
    I'm with a modem of this same model (Datacom dm2270 adsl 2 ft + 2wi) and I wonder if it is possible to use it only as a wifi router, with another modem equipment that came with my fiber hired.
    Thank you in advance!

    1. 8.1

      Good afternoon John Paul,
      Proved that sim, because by default the LAN ports and the Access Point are on the same subnet. In that case you would call your other modem into one of the LAN ports.
      Maybe you need a few tweaks to turn the PPPoE client, or to use the LAN port if you want to stay in this modem IP of Alive and he stays as DHCP server.

    2. 8.2

      Hello! I have the same situation….
      In addition to the instructions of the Skooter, You can apply the suggestion that another friend has posted in the comments: http://www.skooterblog.com/2015/09/30/modem-vivo-wifi-em-modo-bridge-datacom-dm2270-adsl-2ft-2i-askey-rta9211w-rtl8676-2-port-adsl/#comment-19906

      1. 8.2.1

        the tip was great, realmente é possível ultilizá-lo como um roteador , ou seja aproveitar o wi fi dele, após todo o procedimento faz como o amigo lá em cima disse Cara valeu pela dicas…um detalhe importante: em “conexoes de rede”, in the WAN link PPoE, configurar como conexão subjacente “LAN bridge” mas atenção aquinão coloca lan bridge, mas sim a saída de wi fi (wirelles) utilizada.

    Oops my dear. I have a little time Speedy/modem DM2270. Issue: I can't access the all-in-one Epson XP214 for wifi . As the modem has no WPS (or maybe I haven't found) I don't know how to configure it for such. Already released the Advanced mode of the modem. You know guide me step by step on it or not.. know where I can find documentation? Thank you for your attention.

    1. 9.1

      The all-in-one doesn't give you the option to configure it manually by inserting the key WPA? Normally you do not need any adjustment on the router in these cases.

    Good morning, great tutorial, I wonder if that way in bridge it passes the external IP (fixed) the alive to my router, because I use a sonicwall, and I need the external ip (fixed) for remote access and vpn ..

    1. 10.1

      Good afternoon.
      Yes, in bridge mode who takes the external IP of the Alive is the router, as it is he who will run the PPPoE.

      1. 10.1.1
        Alyson Stein

        Skooter, I did all the procedures and I couldn't pass the fixed ip from the modem to my router (SonicWALL), I need because my router does the vpn from my shops.

        1. Skooter

          That IP the router is on? And as modem took the fixed IP?

    Good morning !
    configured in this way I can see my dvr in the external network?
    I'm having hard with that, I can access it in external network releasing the door 91
    ex: in my tp link740nd fixed ip and released the door 91
    Now I can not in any way nor created dns no-ip, dtdns, and nothing!

    1. 12.1

      Good afternoon,
      If you connect it as bridge, the IP goes to your router and you can release the door 91.

    I need some help. I have the DM2270 modem/router that generates the wi-fi signal d alive and also have a link one N300 Mbps L1-RW332 that you want to use as a signal Repeater. The site at link1 has the mode to configure it as a Repeater (WDS- client mode) that is Ok, but at the very end asks to set up the first router (in case the DM2270) to “see” the link1. How to do this in the DM2270?

    Hello there, i’m having a situation with my DM2270, in the QoS > Usage per computers, there is a unknown IP addres that doesn’t meet the DSCP requirements, and it is also not someone else “stealing” my internet bandwith, i’ve measured and confirmed that the amount of the bandwith it uses is the summ of the bandwith the router is using amongst all PCs in my house.
    HOWEVER, the problem is this: I use a software called Netlimiter to, well, limit the top-end of my bandwith on all 3 pcs, so it is effectively shared, and it has been working for over 4 years… The problem is that, over the last few days, maybe a week, i’ve noticed this IP, which is and appears to be from somewhere in california for some reason, when i trackroute,
    disables my ability to limit my bandwith, which really sucks and disrupts any attempt at playing any sort of online games, since noone can limit, they’ll gobble all the bandwith while even watching a simple youtube video.

    I’ve tried blocking it with the IP blocker from the default configuration on the modem, but it didn’t work… any help is welcome,

    Thank you.

    Skooter, I don't know that you're alive, but I have the same modem VIVO that is using, but I have only two network cables (1 for ps4 and other pro PC) and some 3 people use the Wifi mostly night! Q will you can concentrate ”energies” only one device modem with LAN?

    1. 20.1

      I'm not sure I understand your question. You want to prioritize a device, it is?

        2. Skooter

          I no longer use this modem. I don't remember if he has any function to prioritize an equipment. You can search for QoS (Quality of Service) the menus and maybe you'll find something useful.
