    It's just a different notation for using a subnet mask 255.255.255.0

    255 (8bits) x 3 = 24

    I mentioned that in my first post.
    Forget about that for now. It was just an example of using routing
    instead of bridging and how to put the wired adaptors onto a different
    subnet. The bridging option keeps everything on the same subnet and is
    much simpler to configure.

  2. So what can I do to get my Internet connection through to Tiny again? Any
    ideas?

    If you get the bridge working correctly, the Internet should be
    accessible from the Tiny machine without further configuration.

    If it still isn't working after you make those changes i mentioned
    earlier today then you can post some diagnostic stuff like a routing
    table to see what that throws up. Sort the bridge out first though.

  4. I tried that, but at first when I set the bridge to have the IP Address
    192.168.1.200, I couldn't connect to the Internet with Novatech even though
    the icons in the systray told me that the wifi adapter was connected to the
    router at a very good signal strength, the network bridge was connected but
    the local area adapter connection was not. So I reverted to the bridge
    obtaining an IP Address automatically. And would you believe that after a
    reboot the IP address assigned to the bridge was 192.168.1.200 and I have
    wifi connection to Novatech with both local area adapter and network bridge
    connected. Unfortunately the problem still exists that there is no Internet
    connection to Tiny although I can share and amend all permitted folders on
    Novatech and Advent from Tiny, but cannot see or amend Tiny folders from
    Novatech or Advent.

    I don't know what steps to try next but have. written down the ipconfig
    /all for both Tiny and Novatech for you to examine to see if there is
    anything obvious that springs to mind

    It's mostly double Dutch to me but perhaps there is a clue in there.

    The Tiny Realtek adapter settings look to be fine and compatible with
    the Novatech, but the earlier Tiny section is totally screwed. It's some
    time since I used Win98, but have you selected the option to not dial a
    connection in "internet options/connections"? I have known this to mess
    up a wired connection even if a modem is not available (but may not be
    the problem :-( ).

    All the pointers from your post indicate that the Tiny is getting its
    ip and gateway/dns information okay and so you should have a working
    internet connection on it without further configuration. That you
    don't is probably down to the malfunctioning bridge and I don't think
    you will get it to work properly with the kit you have there
    currently. At this point I'd be tempted to look at the routing
    alternative since microsoft's bridging implementation in xp is
    notoriously hit and miss.

    I'll list what you need to do using your existing subnet 192.168.1.0
    and a second wired subnet 192.168.2.0. It's not as difficult as you
    might think.

    First off remove the bridge. Then...


    novatech wireless

    static ip address 192.168.1.200 mask 255.255.255.0
    default gateway 192.168.1.254
    dns server 192.168.1.254 or your isp's nameserver address


    novatech wired

    static ip address 192.168.2.1 mask 255.255.255.0
    default gateway leave blank


    tiny

    static ip address 192.168.2.2 mask 255.255.255.0
    default gateway 192.168.2.1
    dns server 192.168.1.254 or your isp's nameserver address


    wireless router/gateway (already at 192.168.1.254)

    Using your router's web browser interface, set a static route to send
    traffic for subnet 192.168.2.0/255.255.255.0 to go via
    192.168.1.200


    As stated previously you also need to enable routing between the wired
    and wireless interfaces on the novatech xp by editing the registry as
    follows

    System Key:
    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
    Value Name: IPEnableRouter
    Data Type: REG_DWORD (DWORD Value)
    Value Data: (0 = disabled, 1 = enabled)

  7. I believe that earlier section is the connection to the internal modem,
    which I retained in case of emergencies, like losing the broadband
    caonnection. It does in fact work, albeit at the slow d/l speed of about
    28.8 kbps. I did in fact use it a few nights ago as I still can't get the
    broadband link to the Novatech pooter to work yet. And yes I have selected
    the 'Never dial a connection' option, but just in case I took your comment
    as a prompt and just checked to confirmthat I had.

  8. That all seems pretty clear except for one part. That is:
    I don't know how to do that , so will have to browse through the 2wire
    2700HGV pages to find it, so it more take more time and possible help. .

  9. Just found this in my router pages:
    http://www.flyingnun.co.uk/staticroute01.jpg

    Does this mean I just have to add the following

    Subnet IP 192.168.2.0
    Subnet Mask 255.255.255.0
    Gateway Ip 192.168.1.200

    in the relevent boxes and then Add to List?

  14. Well I idd all that and think I correctly carried out all the procedure.
    Unfortunately when I rebooted Novatech, even though the wifi connection
    showed it was connected with a very good signal strength I could not access
    the Internet at all but could see and share Advent and Novatech from either
    of those computers but not from Tiny. Tiny also did not have an broadband
    connection via Novatech.

    Here's the ipconfig /all for Novatech and Tiny respectively.

    I cannot see how to set the DNS server to 192.168.1.254 on Tiny.

    I was wondering if I should have removed any or all of the routes that were
    already in the 'Static route list' in my routetr. but wouldn't know which,
    if any, I should delete.
    Here's the list before I added 192.168.2.0/255.255.255.0 to go via
    192.168.1.200 as you suggester.
    http://www.flyingnun.co.uk/staticroute01.jpg

    Any further ideas for me to pursue?

    If the Tiny settings are as shown, then the gateway is itself, so
    traffic will go nowhere - try 192.168.2.1 (if that's not what is there).

    James Egan Guest

    Yes, that's right. Just change the 0 to 1

    The default gateway for the tiny needs to be 192.168.2.1


    It's on the same tcp/ip properties page as setting the static ip
    address
    No further changes to the router are required.

    Make the changes as shown above then let's have a look at the routing
    table for the novatech and the tiny.

    If you're not sure how to do this, go to a command prompt and type

    route print > c:\rprint.txt

    This will put a printout of your routing table to a file (rprint.txt)
    which you can then paste into your news client and here.

    As well as the routing tables I mentioned you might also check the
    basic connectivity from the various machines.

    From the novatech

    ping 192.168.1.254
    ping 4.2.2.1
    ping google.com
    ping 192.168.2.2


    From the tiny

    ping 192.168.1.254
    ping 4.2.2.1
    ping google.com
    ping 192.168.2.1


    Your router's http interface will likely have a diagnostics page
    allowing you to ping ip addresses from there too. Try

    ping 192.168.1.200
    ping 192.168.2.1
    ping 192.168.2.2

  18. Unfortunately that was a typo PeeGee, and wouldn't explain why Novatech
    wouldn't let me connect to the Internet. Don't suppose it could be a
    firewall problem with Novatech being given the new IP Address 192.168.1.200.
    Will have to investigate that. In the meantime I have reverted back to the
    settings I had before so that I can get Internet access on Novatech, which
    I have now, as you can see.

  20. I've just reset all the settings and they seem OK and I now have Internet
    access on Novatech, but not on Tiny, but at least now when I try to
    explore my network from Tiny it does at least search for, but does not find
    the network . Did a route print as you suggested:

    ===========================================================================
    Persistent Routes:
    None

    Looking at that I cannot see the route that I added to the 'Static Route
    List' in my router, namely 192.169.2.0/255.255.255.0 to go via
    192.168.1.200. I have checked the 'Static Route List' and the route I added
    is in the list, but at the top of the page there is a box containing the
    word 'Errors'
    http://www.flyingnun.co.uk/staticroutelist.jpg
    Could this be where the problem is?

    I also carried out ping tests:

    From Novatech:
    192.168.1.254 all fine, ranging from 1 - 5 ms
    4.2.2.1 OK min 35 ms, max 40 ms, Ave 36 ms
    google.com all fine in range 41 - 44 ms
    192.168.2.2 all timed out

    From Tiny:
    192.168.1.254 all timed out
    4.2.2.1 all time out
    google.com Command prompt just froze, giving no result and wouldn't
    accept any more commands
    192.168.2.1 all fine at 1 ms

    From router:
    192.168.1.200 all fine, ranging from 0 - 9 ms
    192.168.2.1 all timed out
    192.168.2.2 all timed out

    Looks like Tiny can find Novatech, but nothing getting from Novatech to
    it's ethernet adapter
