Networking PC & Laptops w/ Linksys WRT54G & using Aircard 595U for Internet

shandagmiller
I have set up my PC to connect to the internet using the Aircard 595U. I then connected the linksys and made sure all PC's & laptops could see each other. I am now trying to access the internet on my laptops and I am having no success. My PC is 2000 Pro and laptops are both XP. If any one can help me it would be greatly appreciated.

    Have you disconnected your "aircard" as you do not need this as you have a wifi router. I presume that your laptops have wifi connections. If not then you would have to hardwire them to your router for access to the internet, go into the router properties and then get the router to search for your computers, when found write down their ip addresses so that you can access your computers just by their ip address. You might have to make sure that the "DHCP server" is enabled.

    I do not think that I want to remove the aircard since this is the access to the internet. The area where I have my home office does not have access to highspeed internet. Dial-up ONLY. I need the other 2 laptops to be able to use the internet connection that I have thru the aircard. I think it will be set up like a dial-up connection. I am getting stumped on the internet connection shering. Please help!!

    More will come later???. I do not have it working reliably. Sorry about the lousy formating. It would be nice if we could attach RFT od PDF files.

    I have the following configuration:
    3com Baseline 10/100 Hub16 model 3c16410 (is really an unmanaged switch)
    Linksys Hub WRT54G version 2 (Firmware version 4.21.1)
    8 hardwired CAT5 connected computers (with additional wiring for 4 more)
    1 network printer connected via CAT5 (static IP address)
    1 SCO Unit Server connected by Cat5 (static IP address)
    10 wireless connected laptops

    Computer with Aircard 595U USB Modem attached
    1 Aircard 595U USB Modem is in a USB cradle
    Sprint Connection manager is installed on the compute with the Aircard 595U USB attached
    Windows 2000 Professional SP 4+
    Ethernet NIC has a static IP address (192.168.0.40) with Mask 255.255.255.0 and no default gateway.

    Network configuration:
    The 8 computers + Network printer + SCO Unix Server are CAT5 wired to 3c16410.
    The 3c16410 port 15 is connected to the WRT54G port 1 (regular cable).
    WRT54G in WEP 128 mode, shared key, with IP address 192.168.0.1
    ---------------------------------------------

    The issue with making the configuration work is as follows:
    1) The WRT54G wants to be the GATEWAY to the Internet, but the computer
    with the Aircard 595U attached must be the GATEWAY!!!!!!!!!!!!
    2) To manage a network of this size one must have a DHCP Server
    3) The Aircard 595U USB must be in GO Automatic not NIC Enabled
    (Still fooling around with this. Not sure this configuration is correct)

    To counter act 1) the WRT54G is configured in ROUTER mode not GATEWAY
    The computer with the Aircard 595U USB attached is given a static IP address (192.168.0.40), so I know where it is.
    with Mask 255.255.255.0 and no default gateway.
    To provide 2) the DHCP function in the WRT54G must be Enabled

    All other computers NIC/LAN interface is set to automatically obtain their IP Address.

    ---------------------------------------------------
    The system issue is a combination of
    1) the HUB/ ROUTER and GATEWAY to the Internet functions not being centralized in one machine.
    2) The DHCP Server is in one machine and the GATEWAY to the Internet is in another
    This appears to cause an ambiguous and unstable situation relative to determining the GATEWAY address above the
    TCP/IP level of the communications stack.

    The correct solution to all of this is to purchase a HUB that uses a USB interface for the WAN connection.
    To the best of my knowledge there is not one on the market today. Sprint claims that they are working with
    Linksys to provide on the last half of this year. We are in month 8 and counting.

    I have not been able to get back to the URL that described this future product.


    The current issue is.
    The ?other computers? randomly loose the Internet gateway connection. Sometimes the route to
    the GATEWAY (192.168.0.40) is rediscovered. Sometimes it does not rediscover (192.168.0.40)

    You know the route is lost when you rune the ?IPCONFIG? command at the DOS prompt:
    START ? RUN - CMD ? IPCONFIG, The Gateway address will change
    from 192.168.0.40 (GATEWAY) to 192.168.0.1 (the WRT54G). When this occurs the
    computer looses the Internet connection but still has access to the shared resources on the LAN.

    Setting static IP addresses with Mask 255.255.255.0 and Gateway address 192.168.0.40 on the
    ?other computers? does not overcome the problem. It appears that software on the computers
    1) The connection manager on the GATEWAY (192.168.0.40) computer and
    2) The TCP/IP software on the ?other computers?
    exchange the GATEWAY address through a mechanism I have yet to discover and control.

    When it works all work just like hooking up DSL, FIOS, Cable, Satellite, Terrestrial Microwave modems
    up to the WAN Ethernet port of the WRT54GT. When this is lost at the software level, it fails.

    The second Issue:
    The Dial Up Network (DUN )provided by the Aircard 595U USB Modem is either:
    1) not configured the same way dialup 56k modem is:
    2) the connection manager does not support the API to the TCP/IP
    software that allows the ?dialup? connection to be shared

    I am still playing with this aspect, but have not found the way to ?FORMALLY? share the
    Aircard 595U USB Modem DUN connection.

    This device and its software appears to be neither DUN nor WAN. We may be attempting to
    do something the hardware and software were not designed to support sharing of the DVDO link.

    And just buy a router such as:

    http://www.dlink.com/products/?pid=524

    That is a router specifically designed to share EV-DO network products such as your Aircard 595U.

    I'm trying to do the same thing. The suggestion of the 3G router won't work as these are USB broadband modems, not PCMCIA slot cards. Would love some details on what finally worked?

    CradlePoint makes two routers that will work.

    CTR-350 (No battery, has a WAN port that can be used as a LAN port with the latest firmware. You can make you own battery pack for this, instructions can be found on the internet.)

    I have used the CradlePoint CTR-350 for a little over a
    month now and would like to share my thoughts. Since
    this thing takes 5v input, I built a couple of battery packs
    for this and a car charger for this using an extra usb cable
    I had lying around. I made one rechargeable lithium ion
    battery pack that outputs 5v exactly. The other battery
    pack involved 4 AA batteries wired to output 6v. I read
    online that others did this with no problems to the CTR-
    350 even though it lists 5v. I use rechargeable batteries in
    this as well. The reason why I used 4 AA batteries is
    because in case of emergency I can always run to a store
    to buy some more. Radio shack sells a nice 4 AA batteries
    case with cover. You can also add a switching voltage
    regulator to this to keep voltage at 5v. That will bring the
    cost up in making your battery pack. I would stay away
    from the non-switching regulators because they are in-
    efficient and output extra power by way of heat. I rigged a
    8 AA battery pack on my New York trip in Feb and it
    lasted me a whole weekend. As far as I know I still had a
    lot of juice left; I only turned it on as I needed since I was
    running this in my backpack while using my iPhone on the
    EVDO network to find places to go to. The usb cable
    already output 5v, and I already had a car adapter that
    outputs to a usb plug. Incidentally my lithium ion battery
    pack outputs a usb plug too, so i use this same cable to
    connect to my rechargeable lithium ion battery pack. Back
    in the San Francisco Bay area, my friends and family live
    in San Francisco and I work 4 days per week in Petaluma.
    While I have DSL in San Francisco I did not want to pay the
    combined cost for another phone line and DSL in
    Petaluma. Naked DSL and Cable DSL was not cheap either.
    Since I would have to spend at least $40, why not pay a
    little extra for EDVO? At first I thought, I don't really need
    high speed everywhere I go, once you have it you will find
    you use it everywhere. This CradlePoint CTR-350 and my
    iPhone makes it easy for me to stay connected at high
    speeds everywhere I go. I still keep my data plan on my
    iPhone but it is slow. The 595u and CTR350 solution is
    still a little bulky when put together. I would have to put
    in in a carrying bag of some sort. Often leaving this in my
    car is great. Look for my CTR350 hotspot in SF. It is called
    THOTSPOT, WPA2 password is freethenet.

    Final thoughts any compatible EVDO modem and a
    portable router with battery pack kicks ***. If you don't
    want to bother with making your own there are solutions
    out there with battery packs included. I'd like to try the Kyocera Kr1 because you can buy a GPS module for it and
    post your current location on a Google map mashup. Too
    bad these EVDO routers can't take advantage of the built
    in GPS on most of these modems.
