    Had the exact same problem with my new HP touch sleekbook. It kept disconnecting from the network every few minutes..... I tried everything I could think of, disabled firewall, various tools, changed virus software, various settings tweaked, startup items disabled..... NOTHING WORKED....... Then I went on to my router and changed setting from auto channel selection to "always use channel five" (random choice) MY laptop has not disconnected once since....... :) :) :) Hope this helps you too.....

    I thought I would answer your post, as although helpful, may actually cause some issues for people searching and following the advice

    The issue you have would be due to wireless interference and choosing a random channel is not always the best choice
    You need to use a tool like Xirrus to look at what channels are in use and also at the time when the disconnect occurs - what wireless networks are on and in use , often other networks are on auto and the channels change

    for 2.4ghz range of wireless
    there are 1 -14 channels available globally -
    1-11 is allowed in US
    14 only in Japen
    and 1-13 rest of the world
    see this link http://en.wikipedia.org/wiki/List_of_WLAN_channels

    Channels 1,6,11 do not overlap - as shown in diagram attached- so they are often the ones to try and select

    The 5ghz wireless range is sometimes a good alternative , for a crowded wireless environment, if equipment supports that signal
