    Hello,

    Got a very annoying problem - my wifi network adapter (Atheros AR5007EG wirelss network adapter) works just fine for about 50 minutes - and then it shuts down and disappears as if it's not installed on the computer. To make it work, I have to shut down the computer and turn it on again.
    Does anyone know the reason for this annoying problem?

    Thanks!

    does it disappear from device manager ?

    ------------------------------------------------------------------------
    Device Manager
    Post back the results in device manager

    windows key and pause Key should open to allow device manager to be seen on laptops may need to use windows key + FN key + Pause Key
    if not then

    Start > control Panel {Vista set to classic view}> system > {Vista, device manager on left hand side} {XP hardware Tab, device manager button} >
    windows 7
    start > control panel> System and Security> Device Manager

    network adaptors, click on the + > post back the devices listed there
    are there any ! ? or X

    Thanks for the reply.

    That's exactly the problem - it works just fine, when you check the device manager it's listed there.
    After about 50 minutes the wifi sign shuts down (the little computer with the globe turns into black with a red cross mark), and when you check the device manager, under network adapters the line with the wifi adapter (which was there when it was working) is gone, as if not installed at all.

    etaf, do you think it could be the Atheros driver problem that you and TerryNet posted about? Post copied here.


    Ok:This is what we know about that Atheros adapter.Boils down to two possibilities :
    Encryption and or driver issue.
    I think both of those are covered below.
    Courtesy of ETAF and Terrynet on the Networking Forum:

    ------------------------------------------------------------------------
    Atheros AR5007EG & AR5007
    We have recently been seeing a lot of problems with the above adapters over the last few months, mainly concerning WPA and WPA2 encryption and windows Vista.

    The adapter gets an IP configuration, and shows as connected, but communication is non-existent or sporadic.

    Log into the Router and disable the wireless security and see if you are now able to connect to the internet and surf OK.
    --- Please post back here if that works or does not work.

    Here are a number of possible solutions

    --- 1) In Device Manager right click on the wireless adapter and "update driver." That apparently has worked for some posters.

    --- 2) Download and install the latest wireless driver from your laptop manufacturer's web site support section, as some manufactures, appear to now have a working driver available.
    Toshiba - update has worked for some PCs
    HP The latest HP Atheros driver dated Sept 2010 has fixed the issue - so check the driver date, However, that does NOT apply to all HPs / Compaqs machines
    - the poster did an online scan for driver updates on the HP website here HP Product Detection which resulted in a solution. Solved: Can't connect to internet wirelessly - Atheros AR5007 Wifi through Clear Comm - Tech Support Guy Forums

    If you can post the Make and EXACT model of your PC here, along with the windows version you have and we will see if we can find the driver and will post a link as a reply here.

    --- 3) On one occasion re-setting the router back to factory default and re-configuring the router settings has resolved the issue

    --- 4) A few posters here with the same issue have found that the driver from this site ATHEROS drivers for Microsoft Windows resolved the issue

    I do NOT know anything about the site mentioned ATHEROS drivers for Microsoft Windows
    http://www.atheros.cz/

    However, if you do decide to try the driver, Please let us know the outcome

    Direct link to the drivers are below
    You only need to click on the green download button labelled " click to download " and wait, the file will download - you do not need to click on any other buttons to get the download started

    AR5007
    Vista 32 Bit
    Drivers for Atheros AR5007 and Windows Vista
    http://www.atheros.cz/atheros-wirele...et=21&system=3
    Although this driver has shown up in BSODs (Blue Screen Of Death) on Vista SP2 systems, usually conflicting with updated Vista OS drivers like netio.sys, tcpip.sys and other networking related drivers.

    AR5007EG
    Vista 32 Bit
    Drivers for Atheros AR5007EG and Windows Vista
    http://www.atheros.cz/atheros-wirele...et=22&system=3


    Assuming that after all the above the wireless still does not connect to the internet, all I can suggest is to use wireless security of WEP or to get an external USB wireless card.

    no the symptoms are different , this applies to vista windows system where users cannot connect to the wireless - the adapter is always there and available

    it may be worth removing the adapter , if that's at all possible, and reseating

    whats the make and model of the PC

    often on the bottom of the laptop there are some covers and under one of these covers is the wireless adapter - which can be removed

    theres a few links here on removing the wireless card
    http://www.irisvista.com/tech/
    http://www.ehow.com/how_2182747_wireless-adapter-hp-business-laptop.html

    these links tend to need the keyboard remove - NOT all laptops do - some are just under the base
