  • Hi, i bought and actiontec GT784WN, when i try to setup the modem doesn't recognize my isp provider, my isp provider doesn't appear in the isp provider list that come with the modem, can i solve this?

    Thanks a lot and excuse my english

  • If your ISP is not on the list you will have to use the manual configuration for your GT784WN by following the steps below.

    If you are setting this up for the first time, or if someone pushed the reset button, you would have to reconfigure it like it was a new modem. You will need the following from your ISP. You will also need to make sure your DSL LED is SOLID GREEN not blinking. A blinking DSL LED means you are not receiving service and cannot get on the Internet.

    VPI and VCI values

    Connection type

    Once you have this information, connect a computer directly to the unit with ethernet.

    Open your browser and type in the Address Bar and hit enter.

  • I use this mode "RFC 1483 Transparent Bridging" but leave the wireless on (it took ~2 minutes to authenticate and be able to connect to the internet). My problem is that the internet speed would drop to ~1.5Mbps sometimes (the regular speed is ~34Mbps). Is there some thing I can do to improve the connection time and the speed? Thanks

  • Thig,
    If you setup RFC 1483 transparent bridging correctly that would have removed all router functions from the GT784WN. Meaning the wireless would be turned off. Do you have another router connected to the GT784WN?

  • Hi, So my setup: tv cable --> modem --> netgear WNDR3400 (act as DHCP and has its own wireless)--> GT784WN (RFC 1483 transparent bridging, DHCP disable, and has its own wireless too. Thanks

  • Thig,

    Why do you have the GT784WN in there at all? That seems like a lot of unnecessary equipment. The GT784WN is a DSL modem/router and if you have cable TV should not be used at all.

  • I have only one cable modem and it's in the living room. I used the GT784WN in the basement so I can get internet there. I tried to use the netgear as AP but that didn't work, so I switch their jobs.

  • Thig,

    Unless you have DSL the way you are using the GT gateway is not supported. It was never made to be turned into just a wireless access point. It is a DSL modem with a wireless router built into it. Turning on transparent bridging removes all router functions wired and wireless and makes it just a DSL modem. Actiontec does not make a cable modem or a wireless access point.

  • How can I tell if my modem is working properly. We have been having to restart the modem at least once a day to continually receive the internet connection. The wireless connectivity seems to stay connected to my device but the internet access goes away. Any assistance would be appreciated. Al

  • Al,

    This appears to be an issue that several Centurylink customers are having. To confirm this please take a look at this FAQ

    If this is the issue you are having this is something Centurylink will have to fix for you. If not please contact us.

  • I have the Actiontec GT784WN and plan to use it as a direct modem. I am following your directions in changing it to the bridged mode. I have a static IP address assigned so would I still select the RFC 1483 Transparent Bridging or the RFC via static IP?

  • I'm currently using the "actiontec GT784WNV" and I want to add a second router "linksys WRT320N" on the other side of the house. Is it possible to cascade the two routers to get a stronger signal? I have a cat5/6 cable installed from one side of the house to the other.

  • No, you would not be able to do that. You need to connect a wifi extender or wireless access point of some sort. NOT another router, the GT784WNV is designed to be a SoHo class device meaning it is not designed to work alongside another router. Someone with advanced networking skills could get it to work but that is not something that is supported either be Actiontec or by Verizon which is who that device was made for.
