    Hi everyone-

    I've got a puzzler--for me anyway, hopefully someone will have some advice.

    My laptop connects to my modem and the internet, then after a minute or so, it stops working. It is not loading any pages, won't ping anything (request timed out), and is probably not connected to the router anymore since I can't load the router administration from that computer, but I still have a valid IP address, and Windows still insists that I'm connected.

    The laptop internet works fine when using a wired connection. It also works fine when connecting to other wireless connections (work and Starbucks are 2 I've tried). The home network works fine on my Lenovo X61 running Windows XP as well as my LG p-925 (phone) running Android 2.2, my Acer A500 (Android 3.2). So I'm thinking it's a Windows 7 issue with my router, but I haven't been able to find anything on the topic online.

    The router is a Dlink DIR-655

    The laptop is a Samsung Series 3 with Windows 7 Home Premium 64-bit. This one, in fact: http://www.amazon.com/Samsung-NP350...Y8J4/ref=sr_1_1?ie=UTF8&qid=1321148125&sr=8-1

    It is fresh out of the box. I have only installed Firefox, Dropbox, and AVG, which I did at work, where the wireless connection works ...

    A list of things I've tried:
    restarting the router, the modem, the laptop and again ...
    removing encryption from the router
    resetting router to factory settings
    updating drivers on the computer (they were up to date)
    uninstalling and reinstalling drivers for network card
    checking for updates to router (no updates)
    disabling ip helper (don't know what that does, it was just suggested somewhere)
    disabling ipv6 (this appeared to work for awhile, but I left and came back and reconnected and now I'm having the same problem)
    changing DNS servers

    I've had it. What the heck is going on? Any ideas?

    Thanks

    Nevermind. I thought Windows was up to date. Looks like an update fixed it.

    Just kidding. Just like the ipv6 "fix" it appeared to work for longer than usual, but it is back to its usual shenanigans again. I am calling Samsung support on Monday, I guess. I am at a loss

    Make sure you have the latest wireless driver from Samsung's web site.

    Please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector and show ...

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

    Type the following command:

    IPCONFIG /ALL

    [Note that there is no space between the slash and ALL.]

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

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    That's me, "keya":


    If I disconnect and then reconnect, it works for about ten seconds, then stops. Thanks for the help.

    Still want to see the Xirrus output. (EDIT: never mind. :) )

    Using the same procedure as for the ipconfig /all please try these tests ...

    ping 192.168.0.102 (or whatever your current IPv4 address is)

    ping 192.168.0.1

    ping 8.8.8.8

    ping yahoo.com

    Possibly a little interference from other networks, but it shouldn't be causing a problem. If it is, using channel 6 may give better results.

    That dip in the Signal history, unless you can associate it with an external factor such as moving the computer, is a little worrisome, but the signal should still be strong enough.

    192.168.0.102: all work and <1ms

    The router: 75% loss

    8.8.8.8: 50% loss

    yahoo.com: 50% loss

    Interesting since yesterday I was getting mostly time-outs.

    I have tried several DNS options (automatic from the ISP, "Advanced DNS service" provided by the router, 8.8.8.8, and something else I found suggested on a forum) to no avail.

    The D-link has an autoscan feature that picks the best channel for you. I also disabled this and chose my own channel using another utility, which also didn't work. It has to be the computer or Windows 7, no? since my XP machine and everything else works fine.

    OK, well I tried channel 6, and it doesn't help. Thanks for the idea.

    I was about ready to agree and say that the adapter is probably defective, but (from your first post) "It also works fine when connecting to other wireless connections (work and Starbucks are 2 I've tried)." begs to differ.

    Try with your router's encryption disabled ('off'' or 'none' or similar). If that helps then try WPA-PSK (not WPA2).

    Well, I think maybe it's an issue with my computer or Windows 7 64-bit and the router. I have already tried no encryption with the same result. I also reset my router to factory settings in case I had done something wonky to it in the past.

    There are some cases where apparently a particular adapter and a particular router just refuse to play nice together. You might want to try a different router or to try a USB wireless adapter with the laptop at home.
