    I have been using my Thomson TG585 v7 router for some 4-6 years and my 2 laptops for 2 and 4 years respectively.

    About three months ago I started experiencing internet disconnects. I would suddenly lose the connection and my router would disappear from my available wireless connections while it restarted. Some 3-4 minutes later I would be reconnected, too late to pick up on an online game though.

    I have tried 2 laptops and a tablet and connecting via a cable and I still get the intermittent disconnects. I have tried new micro-filters and cables, reinstalling the latest drivers etc. and putting my router high up (following a suggestion from my ISP - I didn't know wireless was subject to gravity :)).

    I recently got a disconnect and found myself on the Thomson page on my browser when trying to access a webpage while disconnected so did a connectivity check. I tried it again when I was connected and it gives me green ticks for DSL, ATM, PPP and IP but not internet where it has a cross and says:

    (tick) Connectivity to Gateway (212.139.192.1)
    (cross) Connectivity to DNS Server 1 (212.139.132.105)
    (cross) Connectivity to DNS Server 2 (212.139.132.107)

    I am at a loss now as to why I keep being disconnected. It appears to have no connection to time of day, a particular program being run or anything else. Some days I am not disconnected, others I get 2 disconnects in 10 minutes, generally 1-2 per day. My ISP is no help, either I end up instructing the mainly Indian tech staff or I get suggestions like putting my router high up. (The router is actually some 6 inches lower than the laptop, sitting next to the tv and other A/V equipment and about 6 feet away from the laptop with no walls, fishtanks etc. in between, only air)

    Having arrived here and been impressed with your answers to other questions I felt I might at last get an answer

    Could be RF interferance from cordless phone, other wireless network on the same or adjacent channel, etc.
    Main reason for having the router up high is to have a clearer path between the router and the computers. This one is in my kitchen and there is one spot where I would have a refrigerator directly between the router and computer if the router wasn't 5 feet of the floor.

    Directions from etaf on downloading, using, and posting results of Xirrus WiFi Inspector to check wireless networks near you.

    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

    http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx
    Direct link to the program is here http://wpc.475a.edgecastcdn.net/0047...etup.1.2.0.exe

    {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 NET Framework installed for the WiFi Inspector to function.

    Run the program

    A user guide is available here http://www.xirrus.com/Products/Wi-Fi...uide1-2-0.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, and also post which network "Adapter Name" (1st column) is yours on the list

    To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
    To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here.
    Full details are here http://library.techguy.org/wiki/TSG_...g_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.
