    Hello. I have an Asus U31JG with WIndows 7 64-bit. This laptop is a month old to me and the wireless has been acting up since the day I got it, will explain below. I believe my home network is the problem. I have a Linksys WRT54G with WPA Personal encryption. Multiple times a day my internet quits working even though Windows says it has full connection to my router. To fix this, I open command prompt and use "ipconfig /release" and "ipconfig /renew". This fixes the problem for me, it may be a minute or a few hours. The problem is very intermittent and only happens at my home which is why I believe it is my network. However, I changed the wireless channel to 1, the only one around on that channel and tried different security settings. My WiFi works flawlessly if I take my laptop to my friends house where he has a Netgear router. I have also tried a brand new Cisco Router as well as a Netgear router at my house.

    I've re installed the driver twice, and the same problem persists in Linux only I just have to disable/enable wireless. Does anyone have any ideas before I send this thing back to Asus?

    Note: When the internet quits working on my laptop it works on other devices so it is not the internet connection causing this. And my internet is very slow when it is working on my laptop via wireless.

    May we see two things :
    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 type CMD in the Search box after Start)



    In the command prompt window that opens, type the following command:

    Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

    IPCONFIG /ALL

    Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
    Paste the results in a message here.

    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

    And:
    Wifi test exe. Hint from Johnwill

    Download and run Xirrus Wi-Fi Inspecto from
    www.xirrus.com/library/wifitools.php
    on the problem machine. Post a screen shot of the main screen(networks screen) here.



    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.

    Note that this application requires NET Framework to run. If you get an error about a missing function, download and install NET Framework.

    Full details are here http://library.techguy.org/wiki/TSG_...g_a_Screenshot

    Make sure you have the latest wireless driver from Asus's web site (assuming you are using the integrated wireless adapter).

    May we see this when you have the problem.Your ipconfig indicates an apparently working wireless connection >
    From a Johnwill post on the Networking Forum


    Try these simple tests.

    Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

    In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:

    NOTE: For the items below surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous IPCONFIG command output! Do NOT type <computer_IP_address> into the command, that won't work. Also, the < and > in the text is to identify the parameters, they are also NOT used in the actual commands.

    Do NOT include the <> either, they're just to identify the values for substitution.

    IPCONFIG /ALL

    PING <computer_IP_address>

    PING <default_gateway_address>

    PING <dns_servers>

    PING 8.8.8.8

    PING yahoo.com

    Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
    Paste the results in a message here.

    <computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above. (For Vista/Win7, the IPv4 Address)

    <default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

    <dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.

    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

    Do you have anything else that uses the 2.4 GHz range? Some cordless phones do; some baby monitors do.

    Is there something in the path from router to computer that may interfere occasionally, such as a microwave or refrigerator/freezer?

    We have 4 cordless phones that operate at 5.8GHz. There isn't a freezer/fridge or microwave in the way of the routers signal.

    This is the first device that hasn't worked properly with our router.

    pedroguy: I haven't had to reset my connection today yet. Maybe this is a good sign but it has happened before. Only time will tell.

    So my wireless did not cut out once yesterday. Today it cut out this evening once for 30 seconds then again, until I reset the wireless. The second time it went out it came back as I pinged 8.8.8.8. I pinged yahoo.com and 8.8.8.8 right after that to show that it went out again. Here are the test results:

    I'd check the Asus web site once a week or so to see if they update the wireless driver.
