    Two laptops and a desktop happly file and print sharing via wireless lan cards using WinXP Pro, then I installed a Broadband Modem/WirelessRouter and all the PC's can talk to the router and access the internet but now they can't see each other (no file or print sharing. I have set all the wireleess lan cards to infrastruture as per the instructions. I have run the 'set up a home lan' wizard on all the PC's and one of the lap tops set up an Internet Gateway and the other two did not, but they still won't talk to each other, and can only see the BTVoyager (Moden/Router).

    Any Help Please Paul

    From each PC, do the following and post the results here. Please identify which PC is producing what results. Just copy/paste the contents of the text files you'll be creating.

    start~run~cmd
    ipconfig /all > c:\ipconfig.txt

    Things seem to change sometimes on power up.

    At the time of these Ip configs the desktop PC can access the internet and can see laptop 'paulslaptop'.

    paulslaptop can access the internet and cannot see the other two PC's.

    The other laptop (shillam-p) cannot access the internet ( don't think it has ever since broadband) and cannot see any PC's.

    Thank you. That helps.

    RE: the 2K PC, SHILLAM-P, not working on the internet - the following settings are stopping you
    DNS Suffix Search List. . . . . . : bull.co.uk
    uk.sterianet
    sterianet


    When the DNS Suffix Search List is populated, the PC won't look beyond what is there.

    As to the PCs not working with each other any longer, I'd have to guess you now have a firewall and it is blocking the systems from 'seeing' each other.

    If my guess is correct, they won't be able to ping each other by IP address.

    If they do ping the others by IP without problems, we need to look elsewhere for the problem. They are all on the same network so should be able to any sharing they are set for and since they did it pre-router, the evidently were set correctly at one time.

    I have cleared the DNS Suffix search list on the NT laptop and can now access Broadband and the internet.
    I have done some pinging and find that both laptops can ping each other but neither of them can ping the desktop. The desktop cand ping the XP laptop but not the NT laptop.
    In My Network Places both laptops can only see them selves. The desktop can see the name of both laptops but can only access the files of the XP one.
    Regards Paul

    Glad to see a little progress anyway.

    I'm going to ignore Network Neighborhood/My Network Places for a while. When everything else is working OK it might be worth a look but there is really no need to ever use it if you know your network setup. Works OK for a small network and a user who isn't familiar with the PCs and shares but certainly not needed otherwise.

    - Do you have any sort of firewall running on any of the PCs?

    - Please clarify exactly what operating systems you have running. To simplify, just match PC name and OS. If XP, be sure to specify Home or Pro versions.

    - Please verify that all your PCs are using exactly the same workgroup name.

    - All NT systems (NT4/2K/XP) if they are to properly share files/folders/printers/whatever over the network will need to know who is trying to connect. In a workgroup environment, this piece must be done manually. All the PCs will need to have the user logging on with a username and a NON-BLANK password. After that, you can set up in one of the following ways:
    - Same username/password for logging on to all of them. (easiest if it meets your needs)
    - Different username/password and each user account entered into the local users section on all PCs. (most secure and offers the most options)
    - Enable the guest account on all PCs. That will enable any username/password to provide access. (least secure and somewhat limited acces for all users)

    I'd also recommend you set each network card to use a static (fixed) IP address. You can leave DHCP enabled since the static data will over-ride DHCP for those values but DNCP can still assign any others. The address/subnet mask you listed in the Ipconfig data above will be fine.

    After you make the addresses and netmasks static, place a hosts file on each PC (or modify the one that is there now). Substitute your real PC names and ip addresses but the form is as listed here. Just create a text file and name it hosts with no extension. On NT systems, it should be copied to %system%\windows\system32\drivers\etc (normally c:\ for %system% and possible that your windows folder is named WINNT rather than windows):

    192.168.0.2 PC1 Pc1 pc1
    192.168.0.3 PC2 Pc2 pc2
    192.168.0.4 PC3 Pc3 pc3

    I listed each PC name with the main case variations so it would be found no matter how you typed the PC name.

    Non of the PC's have any firewall enabled.
    One laptop is running Win 2000 Service pack 4
    The other two machines are running Win XP Ver 2002
    A correction to my previouse, the 2K laptop can see and access the files of the other laptop providing I leave it a long time before I try.
    It might take me a while to try the other suggestions as I am not sure how to do some of them.

    All the PC's use a workgroup of 'workgroup'
    The Win2K laptop is called shillam-p
    The XP laptop is paulslaptop
    The desktop is fredfred

    The other stuff you have asked me to try, static IP address and renaming, I don't know how to do...sorry

    Paul - the PC names and workgroup name you have now are fine. I was using different ones just by way of example.

    Change the IP address information to static by getting into properties for the network connection and then properties for TCP/IP and changing from automatic to 'Use the Following ...' and putting in the values. I'd keep the same IP addresses they have now with a subnet mask also the same as well as the default gateway. You should be able to keep DNS info being autoassigned.

    If you keep the same addresses you have now, your hosts file should be

    192.168.1.4 SHILLIAM-p Shilliam-P Shilliam-p shillam-p
    192.168.1.3 PAULSLAPTOP PaulsLaptop paulslaptop
    192.168.1.2 FREDFRED Fredfred fredfred


    In fact, you could save some typing by just copying the above and pasting it into a text file and naming the file hosts then putting it into the folder I mentioned above. Same file on each PC.

    I have changed all 3 PC's to static IP address's it wouldn't let me keep the DNS autoassigned so I put in 192.168.1.1. Unfortunately this has not made any difference to my problems. The laptops still can't ping the desktop (fredfred) but the desktop can ping the laptop 'paulslaptop' but it can't ping the Win2K laptop 'shillam-p'.
    The connection I realy won't working is paulslaptop to fredfred as I use to use Remote Desktop from the laptop which ofcourse is now not working.
    Regards Paul

    From what you say, your networking setup is correct and should be working unless something is broken.

    Sounds like a problem with the network load on the desktop or possibly with either the cable or the switch port.

    Easiest to try a different patch cable and a different switch port. If that doesn't fix things, I'd try starting from the beginning with it.

    - device manager and remove all network components.
    - shut down, remove the network card, restart.
    - shut down, install card (making sure you have the latest drivers available) and restart to let the PC reinstall the NIC.
    - set up networking on it again.

    This is a wireless network hence no cables to remove.
    I have tried deinstalling everything and restarting but no luck.
    I am assuming that the broadband modem with it's built in wireless router is blocking the pinging of my desktop PC (fredfred)
    But not knowing what a router does in great detail I am unable to fault find this.

    Oops on the 'cables'. Forgot you were pure wireless.

    A router routes TCP/IP packets. Dumb sounding answer I know but that's about it.

    Your network traffic on your local network (a group of IP addresses that work together based on the address and the subnet mask) should be able to get to and from any of your devices without help - at least they should if there is some way of matching IP address to PC name as the hosts file will do for you.

    For packets to find their way outside your network, they need the services of a device that is familiar with part of the outside world. The Gateway address on each PC should point to the router so that any traffic that is the wrong addressing to be local will go to the router via that gateway IP address and the routing information within the router will take over from there.

    For the SOHO router/switches, about all your local router will know to do is pass packets along to a larger router at your ISP. If it can't figure out where a packet should go, it will in turn pass it along to a still larger router out on the internet somewhere.

    I'll have to get back to a thought I mentioned earlier - that you have a firewall that is blocking your PCs from working together. I did a quick bit of research on BT Voyager and it looks like many (all maybe) have firewalling features. In that case, you usually have to do some configuration work to allow free passage of packets to and from all your local IP addresses.

    If that isn't it, I have to admit to being totally baffled. There may be some specific wireless thing I'm not familiar with since all of my work is with wired systems.

    I have purchase a new wireless PCI card for my desktop (fredfred) and installed it as adhock pier to pier connection. I have set the same on the laptop (Paulslaptop) and the wireless cards talk to each other as before but I can only ping from fredfred to paulslaptop and not the other way. All firewalls are dissablbed as is Norton Anti Virus. This is driving me cazy.

    Paul - I'd suggest trying a forum that specializes in wireless broadband. There is probably some simple thing that no one here is aware of. If you do try and do get a solution, please post back with details.

    If the forum allows it you might point them to this thread as background reading.

    I haven't personally examined these but all of them are specialty forums and all have currently active threads.

    http://www.broadbandreports.com/forum/wlan

    http://www.dslreports.com/forum/wlan/ (same MOD and maybe the same forum)

    Just treat the wireless the same as you would wired when networking. Don't use the wizard. Just use Client for Microsoft Network and TCP/IP and sharing for printer and files. It you have anything other protocol intalled get rid of it. Don't use ad-hoc on anything, that is only if you don't have a router. The router is the DHCP Server acccording to ipconfig you have posted.
    Go to the Network Connections folder in XP go to advanced and then advanced setting make sure under wireless connections that TCP/IP is bound to Client for Microsoft Networks and Printer and File Sharing . Here is a link for 2000 since it has been ages since I've used it http://support.microsoft.com/default.aspx?scid=kb;en-us;258717. Enable netbios over TCP/IP also.
    If you are using simple file sharing in the XP machines you will have to enable the guest account with a password. I don't think 2000 uses the simple file sharing. It is simpler if all the profiles and passwords are the same . Make sure they are on the same workgroup. Share folders on each machine. I have pro on allmy machines and don't use simple file sharing. XP pro filesharing http://www.practicallynetworked.com/sharing/xp_filesharing/index.htm this is a good site for networking.
