    Well, it has to dial something to establish connectivity with the ISP. You have to dial into their PPP server. The user has to run the connection application to initiate the connection.

    ONLY DSL uses dail-out. PPP is a protocol of packets sent over the connection.
    eg: A VPN connection (regardless of the connection) is always performed using PPP.
    Sometimes one does have to initiate a connection from the user's system,
    but most frequently, when the hardware sees the device is ready (as in plugging the dongle into the router)
    the connection is automatically initiated.

    On a Cable-modem, as soon as power is applied the device connects to the ISP even if the system itself is not attached or powered on.

    ONLY DSL uses dial-out.

    I don't claim to be an expert. But, actually VPN does not always use PPP. I dont see any possibility that could allow the usb dongle to determine that it is connected to a router not a pc and then auto connect to the ISP. Therefore the router has to instruct the dongle to connect to the ISP. Be warned I am no expert but this is my understanding. Btw i didn't ask for an explanation of what PPP is.

    Certainly you cannot connect devices that are powered off or not attached. Maybe you mean it tries to connect (while with power).

    I dont really understand this only dsl uses dial-out thingy, care to explain why?

    Maybe better said or shown as
    a) power off Modem
    b) disconnect Cable to router or system
    c) power on Modem

    result: ==> modem is connected to the ISP without user interaction

    d) connect cable to router or system

    result ==> System has Internet access without user interaction.

    Now let's get back to helping this poor guy solve his problems.

    and the PPP/PPoE descriptions are at this wiki

    OK, here's the update.

    I took a snapshot of the network config page before I made the changes. (Notice the MAC addresses on each of the interfaces).

    [​IMG]

    I changed [cloned] the MAC address to the MAC address of the dongle and performed the following:
    DISABLE [ ] IGMP Proxy and Ping Access on WAN
    Enable [x] Web Search access on WAN
    MTU set to 1492
    and took another snapshot. WAN Connection (3.5G) still disconnected.

    [​IMG]

    I did notice in a jpg sent to me from the team in Sapido that all of the MAC addresses were one & the same. I don't know whether that makes any difference at all?

    Apologies over the size of the pics again!

    OOPS; clone the MAC address of your system NIC card!

    Gotcha! ;) Yes, done now & changed LAN MAC address to same. Now all MAC Addresses the same but 'Attain IP Protocol' still saying 3.5G disconnected. Have tried with both IGMP box checked & unchecked.

    I didn't read through all the posts so excuse me if this has been solved. When you were trying to log in to your router with 192.168.1.1 did you have the ethernet cable going from your computer into a wired connector 1-4 on the router and NOT on the "Internet" connection?

    @Buckshot - Yes. 4 port router w/USB port which is used as WAN port (via 3G USB dongle). Router also has a separate WAN port not being used.

    Router can only be logged on when 3G USB dongle attached direct to router. However, have to plug USB dongle direct to PC for internet access currently....

    It is a 3G Mobile Broadband Router?

    Is this of any help?

    did you also set DHCP instead of Static?

    Yes, DHCP jobeard.

    OK, now I am stuck. With the router setup as
    1. router mode
    2. DHCP configured
    I'm left with only two comments
    a) it is NOT your system (ie the dongle ->system connection works)
    b) and the typical settings do not work

    Sheez I hate to mention it, BUT ... call the Router Support People to get their
    recommendations for the 3G Dongle implementation,
    and then the ISP itself.

    Thanks jobeard. Very much appreciate all your time & effort. Sincerely mean that!

    Sapido have said they will log on remotely so will see how that goes.

    Thanks to everyone else too for you help & comments!

    Does the modem get an IP? I believe no. So it is the same with DSL modem it doest get any ip. It is the WAN interface of the router that receives IP addresses (without user interaction)

    It is the WAN interface of the router that receives IP addresses. And the user dont need to configure any settings, only connect the router and modem. The same with DSL.

    Thanks but I know enough about ppp. What im really curious is, is about "ONLY DSL uses dial-out.", I dont understand this dial-out/in.

    Btw the mac of the PPP adapter 1.3G (usb dongle) is what the ISP is probably checking for (if it is checking for mac).

    Tried changing this, but made no difference, so ISP is probably not looking for it. The IP of the dongle when connected directly to the system (PC) changes so it is using Dynamic IP addressing. Also, it always has DHCP enabled = No. Not sure whether that is relevant or not??

    Your 3G usb dongle is like a cellphone, it calls (in a sense) your isp to establish internet connectivity. Your ISP probably uses your sim card number to identify you from the rest of the callers. The app that came with your usb dongle has pre-configured settings, these settings are required for you to successfully connect to your isp, my guess....
