Sharing Internet connection w/ 3G broadband card

  1. Greetings from NYC ........

    I replaced my ancient laptop w/ Dell M4300 with ATT 3G B/B - Dell 5520 card. Laptop and 3G are working great; excellent speed in NYC area!

    I wanted to setup a ICS configuration for several other wireless laptops but can not get connectivity to internet from "client" workstations; M4300 works fine and connects to ATT "cloud" but other workstations can not resolve DNS, etc.

    Used the Wizard ... no help; configured the system manually ... no help; tried hard-wired clients through mini-switch ... no help; tried direct connect to client workstation w/ X-Over cable ... no help.

    Tried every combo of firewall on/off settings I could imagine ... no help!

    I have done this succesfully in the past with older "air cards" w/ CDPD. Worked fine but slow; I was expecting a speedy, portable, wireless mini-network w/ the 3G card.

    Anyone know if ATT or Dell defeat the ICS feature on the newer 3G cards / connections?

    Any work-around?

    Your help is appreciated

    This implies a network looking like
    Not cool at all :(
    Get a 4-port wireless router and you can have
                + --- system
                + --- system
                + --- system
    some wired and several wireless. You'll be much happier :)

    Mr. B:

    Thanks for the reply; I was hoping to configure the laptop to be a "mobile wireless router" by using the onboard 3G card as the "WAN" side and the onboard 802.11G Wi-FI as the "wireless LAN" side.

    Any further insight to the solution?

    regards, dadlives2

    You're not the first to attempt that approach. However, the WiFi cards in our systems
    are basically receivers and they receive from a router that is the sender :)

    ~ $49 U.S.D will get you a usable WiFi router -- I'm sure any brand will do, but
    be advised that using a Belkin router with other vendor WiFi adapters has been
    "unpleasant" in the encryption area.
