    Dear Members,

    Look for alternate internet connect with 3g dongle when bsnl broadband fails.

    Present connection:
    Bsnl broad band connection with wifi modem cum router is connected to 8 port switch for LAN.
    total 5 wired system connected for lan and internet.

    Requirement : When bsnl internet connection fails, internet should be available with 3g dongle.

    Router with USB port which can use one port for 3g/4g

    Sir,
    Dont know supported dongles.

    Also tried the below;
    http://www.amazon.in/TP-Link-TL-R47...17&sr=8-1&keywords=tplink+load+balance+router

    along with Tplink 3g/4g dongle and router along with load balancer,
    Problem facing : If internet connection connected to the first WAN port fails, No internet will be available with 2nd and 3rd WAN port. Tried a lot with Tplink customer care, not successful.
    Thanks a lot.

    @vivek.krishnan
    requested to light to resolve.

    Firstly, this is an expensive way of doing it, but you can tether mobile phones, dongles - anything even doing RNDIS etc

    Get the 470 TP Link, setup as dual WAN, single LAN and WAN1 (Static,PPPoE, etc) as main and WAN2 (DHCP) as failover. Ensure your monitoring IPs are good as failover depends on the ping response.

    Buy a DLink DIR 505 - 1K approx, install ROOTER, setup the USB as WAN and Ethernet as LAN - use a different IP. This LAN should be connected to WAN2.

    Ensure that you setup the correct monitoring IPs as 8.8.8.8 and 8.8.4.4 for each WAN. Note that a small amount of traffic will be hitting the dongle.

    The cheap way out would be to get a router that supports OpenWRT - specifically ROOTER, and has the USB port for dongles. But doing failover might be difficult. I believe @chetansha has a R7000 for sale, that might be capable of doing this.

    If this is for an office, I would suggest to setup Pfsense instead of the TP Link box with Intel - you will love the RRD graphs.
