    Laptop drops out every 20 minuites or so, sometimes more often. The desktop that's wired doesn't suffer.

    Windows 7 Network Troubleshooter fixes the problem, but then the connection gets lost again minutes later.

    The Network troubleshooter diagnosis states (but means little to me):-

    If you're connected to a hotspot or domain network, contact the network administrator. Otherwise: 1. Unplug or turn off the device. 2. After all the lights on the device are off, wait at least 10 seconds. 3. Turn the device back on or plug it back into the power outlet. To restart a router or access point that has a built-in battery, press and quickly release the Reset button.

    Things you could try to fix this:

    1) Ensure that you are within the Wireless range of your Wireless Router and that there are no obstructions. Also ensure that there are no speakers located near the router itself as the magnetic fields could hamper the signal strength.

    2) Ensure you are running the latest firmware of your router. If you are not sure, go to your router's website, then go to support, then select your router model, and see if there are any firmware updates

    3) The next time your Laptop disconnects from the router,

    Click on the START MENU, then ALL PROGRAMS, then ACCESSORIES, then right click on Command Prompt and select Run As Administrator

    While you are in the command prompt type:

    ipconfig -release
    wait for 5 seconds
    then type:
    ipconfig -renew

    4) If all those don't help, then consider checking for a driver update for your WiFi chipset/card

    Try changing wifi channel your router is broadcasting on. Set your network as trusted in whatever security software you are using. Does the connection improve if you are close to the router?

    I'm was having similar issues connecting to new Sky (Sagem) router last week. When I closed and shut down Online Armor the problem went away. OA now uninstalled and the issue went away permanently after next Network troubleshooter run. Could just be coincidence but I notice you use OA too.

    Best of luck.

    It looks to me as though your AP is -36 1 virginmedia6170374 and it would be better off on a different channel. The next strongest signals at that time were:

    -52 1 TALKTALK-01C8D8
    -62 1 virginmedia3616948
    -58 6 SKYF1C0E

    My gut says channel 8 or 9, but I'd sniff a bit first. There may be better free tools (suggestions anyone?), but I've been using MetaGeek inSSIDer (http://www.metageek.net/products/inssider/) to get a sense for wireless environments. I do something like this:

    1) Run that on two notebooks that are disconnected from all wireless networks (just in case one of them has an Rx problem).
    2) Watch it for awhile to get a feel for the environment as is, looking for signs the signal strength from the AP in question is fluctuating badly and looking for the quietest channel to move it to (may require walking around if a larger usage area).
    3) Consider the proximity of interfering devices and whether moving them or the AP is an option. If you are willing to spend the bucks, or can borrow one, a more sophisticated spectrum analyzer would come in handy here.
    4) Power cycle the AP and see how it looks afterwards. Some seem to fade after being on for a long time, and simply cycling power restores a solid connection for awhile.
    5) Move the AP to the preferred channel, make adjustments to Tx strength if possible and desired, look everything over while in config
    6) Experiment with minor tweaks to AP location and/or AP antenna positioning. Relatively small changes can sometimes produce nice gains.
    7) Make changes as appropriate on the client side, then connect and (hopefully) enjoy a more solid wireless experience. Experiment some more if warranted.

    Edit: It just dawned on my you are likely in the UK and thus should have for example 2.4 12 & 13 to possibly make use of. I also didn't get into 5GHz options above. In any case, if you download something like inSSIDer you'll have something visual to share and there will probably be a forum and...

    For the longest time I had this problem and I just uninstalled and re-installed the drivers one day, and now everything is fine.

    Just an fyi for you baby monitors as well as older cordless phones will affect signal of wifi your neighbors if they have young kids like under 4 may use a baby monitor.

    The Routers Wireless Range Needs To Be Expanded

    TO EXPAND THE ROUTERS WIRELESS RANGE:

    01] Change the Beacon Interval to 50
    The router sends out beacon packets to all the wireless clients to retain the wireless connection.
    Sending beacon packets every 50 milliseconds instead of the default 100 milliseconds will retain the connection.

    02] Change the RTS Threshold to 2304
    Reducing the Request To Send (RTS) Threshold improves by enhanceing the communications between router and computer.

    03] Change the Fragmintation Threshold to 2304
    Reducing the Fragmintation Threshold fragments large packets into smaller packets for more reliable access by the
    computers on the receiving end.

    04] Change the WiFi Broadcasting Channel to 8 or 9
    Changing the WiFi Broadcasting Channel to 8 or 9 reduces interference caused by surrounding devices broadcasting
    signals on the same dafault channel 6 of the routers wireless antenna(s).


    Should you encounter inconsistent data flow change the:
    RTS Threshold to 2306
    Fragmintation Threshold to 2307

    Check device manager>network adaptors>your wireless adapter>(right click)properties>power management> untick (if ticked) allow computer to turn off this device to save power.
    Also check control panel >power options>change plan settings>change advanced power settings>wireless adaptor settings >power saving mode
