    I am using ethernet for internet access n that's all fine.I downloaded connectify-me(free) for hotspot for my mobile and that was also fine.but a few months back connectify was showning that there was no wifi adapter in my laptop,I checked device manager and network connection(ncpa.cpl) that there was no wifi adapter,so downloaded wifi adapter driver from hp center(i couldn't find windows 8 version,so i downloaded 7),after restarting my laptop that wifi was ok.but again after few days same problem occured,i tried to reinstall the driver but this time that not worked.thereafter the wifi adapter vanishes automatically(sometime for 3-4 days, sometime for 10-15min) and also shows up automatically(and it's ok for next 4/5/6days).I tried many things searching the problem on internet,and finally i upgraded windows 10.but the problem still exists..PLEASE HELP ME TO OVERCOME THIS..(my laptop's ethernet is fine,so i can use internet)
    I am currently using windows 10 32-bit operating system.

    try a tcp/ip reset - see below
    also can we see a device manager - see below
    ------------------------------------------------------------------------
    What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past/
    Any trial ware - like Norton, kaspersky or Mcafee which are often pre-installed on PCs
    Or any other free security suites like zonealarm, AVG , Webroot etc
    ------------------------------------------------------------------------

    ------------------------------------------------------------------------
    Check the wireless is switched ON

    theres often a physical switch or a combination of the FN and one of the F keys to toggle the wireless on/off
    often F2 is used - but note , not always - look for a symbol that looks a little like (( i ))

    is the wireless on?
