    Hi,

    I have a Desktop PC connected to the Router via ethernet and a Laptop
    via the wireless connection (PCMCIA wireless card in Laptop).

    With this setup, I have a problem seeing either PC from the other
    although I can access the internet fine from each machine.

    When I swop the Laptop's Wireless PCMCIA card for a regular wired
    ethernet card and plug into one of the spare wired ethernet ports on
    the router I have no problems seeing either PC or accessing the
    internet.

    Here's the summary with the Wireless PCMCIA card in the Laptop:

    - Wireless Laptop connects wirelessly to Dlink and accesses Internet
    fine
    - Desktop PC connects to Dlink via ethernet and accesses internet fine
    - Desktop PC shows up laptop under network neighbourhood but double
    clicking it gives "laptop is not accessible The network path was not
    found"
    - The Desktop PC's shared folders show up on the laptop under local
    network but I can not open them from there. I get "\\Desktop\Folder is
    not accessible. You might not have permission to use the file. Contact
    the administrator of the server to find out if you have access
    permissions. The network path was not found"

    Pulling the Wireless card from Laptop and exchanging with NIC and
    plugging into one of the unused Dlink wired ports gives a much better
    story:

    - Laptop PC connects via ethernet to Dlink and accesses Internet fine
    - Desktop PC connects to Dlink via ethernet and accesses internet fine
    - Desktop PC sees shows up laptop under network neighbourhood and
    double clicking it shows up the shared folders on the laptop (I can
    open files within).
    - The Desktop PC's shared folders show up on the laptop under local
    network and I can open them from there.
    - Printer connected to Desktop can be accessed by laptop and used
    fine.

    Do I need to do something to make the Wireless network talk to the LAN
    with this router?

    Cheers in advance

    You don't say what you are running, but it SOUNDS like a firewall issue.
    If you are running XP SP2 on the laptop, make sure that file and printer
    sharing is allowed through the firewall for the wireless connection, and
    do the same for any other firewall you have on the laptop, adding the
    wireless connection to a trusted zone or similar.
    Hope this helps

    Just incase anyone else has this problem, the solution was a little
    strange but it did work. I had used the "set up a home or small office
    network" wizard when I had set both PC's up on the ehternet side of
    the router and everything worked well.

    Pulling the laptop PCMCIA ethernet card and replacing with the
    Wireless PCMCIA card gave me internet on the laptop through the
    wireless side of the router but no access to the wired LAN (and hence
    the other PC).

    Just rerunning the "set up a home or small office network" wizard
    exactly as I had done before seemed to work things out. It's not the
    most intuative step but afterwards I could share files and the printer
    across the wired to LAN network.

    It is DEFINITELY NOT the router. Running exactly the same setup here.
    If he's running Sygate Firewall, he needs to select the PCMCIA NIC in
    Sygate and check the file and printer sharing boxes.

    To fix the problem I didn't have to do anything with the router or
    firewall (I had Zone Alarm set up but it would allow the correct range
    of IPs - 192.168.0.xx assigned through DHCP to connected devices). In
    any case, these settings had to be fine as the PCs could share files
    and the printer without problem when they were connected [via the
    router] on the wired ethernet side.

    The problem occured after removing the Laptop's ethernet PCMCIA card
    (hence removing the Laptop from the wired LAN) and putting in the
    wireless card on the laptop (to connect to the LAN via the wireless
    side of the router). At this point the PCs could no longer access each
    other.

    As mentioned, the problem was solved in the end by re-running XP's
    'create network wizard' on the Laptop with exactly the same values as
    given before - ie. something along the lines of hitting the 'next',
    'next', 'finish' buttons.

    This isn't especially intuative as you would think the laptop would
    notice the change of access medium and adjust accordingly rather
    needing the user to re-run the network wizard considering a network
    was already in place.
