    I have a windows vista pc networked to a second pc. I have wirelessly networked internet to 2 laptops. I have an actiontec wireless modem by verizon. All of a sudden my host pc started randomly losing internet connection, but the wireless laptops still have a signal. It seems like the host sometimes can't "see" the modem.
    Here are my settings while the internet is functioning.

    any reason you have it setup like this ?

    and a fixed IP on the wireless

    do you mean you have bridged the connection between wireless and ethernet on your PC ?

    I have no idea. I never changed the settings myself. I don't know why it all changed. What do you suggest?
    I even got a new wireless router/modem from verizon and still the same problem. Laptops work fine, but networked pc's do not. I know there is a setting wrong, can't figure out what.

    It started when I took the router/modem off the desktop and put it downstairs when the power went out so i could use it with the laptop while the generator was on for power.

    can we have a detailed idea of the setup

    make and model of the modem and the router , and then how all the devices are connected to the router
    wireless cable - exact details please

    if wireless can we also see an xirrus screen shot from the PC and also indicate where the PC is located with respect to the router

    ------------------------------------------------------------------------
    Run Xirrus Wi-Fi Inspector
    Download and install

    If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
    Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and install the program.
    You will now need to take a screen shot and copy that back to the working PC and attach the screen shot in a reply on the forum here.

    http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx
    Direct link to the program is here http://info.xirrus.com/Wi-FiInspectorConfirmation.html

    {If the above link does not work heres another link http://www.pcworld.com/downloads/file_download/fid,77196-order,4/download.html}

    Then run and install the program - on a wireless enabled PC/Laptop
    if you get an error - You need will need to have NET Framework installed for the WiFi Inspector to function.
    On windows 8 - (i do not have windows 8) but, it would appear that, When you first try to run, you may get a message that .net framework is needed, and included in that message is a link to download/install.

    Run the program

    A user guide is available here http://www.xirrus.com/cdn/pdf/Xirrus-Wi-Fi-inspectorguide-1-2-1-RevB-6.aspx

    post a screen shot of the program running.
    if there are a lot of networks showing can you click on "networks" top lefthand area - so we can see all the network information.

    post which SSID name is yours, its located in the list, under network "Adapter Name" (1st column)

    To post a screen shot of the active window.
    1) hold the Alt key and press the PrtScn key. Open the Windows PAINT application (Start> All Programs> Accessories> Paint) and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
    OR
    2) if you are using Vista/Windows 7 you can use the "snipping tool" which is found in Start> All programs> Accessories> Snipping Tool

    To upload the screen shot to the forum, open the full reply window ("Go Advanced" button) and use the Manage Attachments button to upload it here.
    Full details are available here http://library.techguy.org/wiki/TSG_Posting_a_Screenshot

    Note:
    For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better. "A desirable signal level for a robust Wi-Fi connection will be green".
    note: the signal level is a negative number, so for example -88 is worst and -40 is better

    If you are using the Mac OS then use http://www.istumbler.net/ or
    if you want to optimise base station position and signal strength / dead spots use
    http://www.chimoosoft.com/products/apgrapher/ which has a graph function to monitor signal

    what do you mean exactly by HOST ?
    how is it different to any other PC

    its the fixed IP you have setup thats I suspect is the issue - as its using 192.168.0.1 as an IP address and thtats normally the gateway = so i would not expect it to work at all
    rather than
    intermittent

    turn the HOST off and lets see an ipconfig /all from one of the other working PCs - i suspect its set to automatic IP address

    then we can change the "host" pc

    I was looking through my network settings and found finding ip address automatically was unchecked. One click and it worked. By the way, I touched nothing. Seems gremlins were running amok in my pc will the electric was off. Now I can only hope find mistakenly click the right thing on my networked client so it sees the ICS.
