LAN ethernet and Wifi internet not working together now

  1. Hi,

    For about 4 years I have had the ability at my work place to access the LAN from my desktop via an Ethernet connection and at the same time access the internet via Wifi to a router+DSL connection. I just switched to Fios which means a new router.

    Now for some reason I cannot have both connections functioning at the same time.
    When they are both running:
    -I cannot access internet (Wifi connects just fine, strong signal, etc... but browser can't find any addresses). If I unplug the Ethernet/LAN cable, the browser - internet access is fine.
    -I cannot print to a LAN network printer, though I can still access the server on the LAN and run programs that are located on the server. If I disable the Wifi, I can print to a network printer fine.

    I really need to be able to do both again. E.g when I am away, my desktop will need to be connected to the internet so I can connect to it via Logmein and access files/programs on the server.

    Here is a printout of "ipconfig /all" from my desktop:

    A few years back I wrote down some ipconfig info - this is when things were working well:

    Windows IP Configuration
    Host: Doctor
    Ethernet Adapter Local Area Connection
    IP Address: 192.168.1.5
    Subnet Mask: 255.255.255.0

    Ethernet Adapter Wireless Network
    IP Address 192.168.1.101
    Subnet: 255.255.255.0

    Thank you so much!!!!!!!!!!!!!!!

    On the host SERVER, you need to change unknown to Hybrid
    with this regedit

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters\]
    "DhcpNodeType"=dword:00000001
    "NodeType"=dword:00000008​

    Also set the DHCP Enable to yes.

    Now if you really need a fixed ip address for SERVER, will get back to that after both wifi & wired work.

    Jobeard,

    Do you mean that changing the node type to Hybrid and the DHCP Enable to Yes on the server will help my desktop work with wired/Ethernet and Wifi at same time?

    I've made changes to the registry of other computers but that is usually hunting for and deleting entries for uninstalled software. Could making these changes to the registry interfere with other computers access to the server on the network?

    I probably should check with the person who initially set up the network and see if this is OK for however he had things set up. (I tried asking him about the above problem with my desktop and Wifi and he wasn't able to help.)
    The server has our patient records software/system that we use all day long, it would be quite stressful for everyone if we couldn't connect to the server properly.

    On the other hand , backing up the registry before making changes should allow me to revert to the old settings if there was a problem.

    Thanks!
