    Hi guys,

    I cannot connect to my wireless network here at home. I see the network in the list of available wireless networks, but when I try to connect to it, the pc gets stuck at "identifying" and never gets on. Rarely this will occur on other networks as well, but I almost always can connect to networks other than my home one. The network works with my pc if I use a wire it, but it almost never does wireless. I also have three roommates all who can connect to the router wireless with no problems whatsoever.

    I'm currently running Windows 7 on my laptop with an Intel Centrino Advanced-N 6200 AGN wireless card.

    So far I have tried the following:
    -disabling firewall
    -updating wireless drivers
    -turning off/on the modem and router

    The last option (turning off/on the modem and router) has worked, but it seems to only work for a couple of hours, sometimes even less, after I reset the modem and router. Also, sometimes I get the "Windows detected an IP address conflict" message.



    This is my ipconfig /all:

    Make sure you have the latest wireless driver from the laptop manufacturer's web site. If you already have that driver reinstall it in case the installed instance is corrupted.

    What firewall or security suite is, or ever was, on the system?

    TCP/IP stack repair options for use with Vista and 7 and 8.

    Start - All Programs - Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt. [For Windows 8: <Windows Logo> + x - Command Prompt(Admin)]

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

    Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

    Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

    Reboot the machine.

    I tried all the stack repair commands and ran them through cmd as administrator and rebooted. Unfortunately it did not fix the problem.

    I also tried downloading the wireless driver from Dell's website (I have a Dell XPS laptop), but it told me that I already had a newer driver and I couldn't seem to figure out how to roll it back; the option was not highlited.

    I just run Windows firewall with AVG Anti-Virus Free Edition.

    Any other ideas?? I really need to use my wireless :(

    You couldn't download the driver or it wouldn't install after the download?

    Try using Device Manager to uninstall the adapter and then run the Dell installation program again. Sometimes a motherboard or PC manufacturer needs to modify the original Intel driver to make it work in the specific system. So it's always good to try the latest from the PC manufacturer, and only if that doesn't work try the one directly from Intel.

    I uninstalled the driver and then tried to install the one from Dell, but it said that a newer one was already installed. So I tried restarting the pc, but when I got back to my desktop it automatically reinstalled the driver that I wanted uninstalled :\. I don't know how to stop it from doing that

    That makes no sense to me. I'm not doubting what you are saying; I just don't understand how that can happen.

    Try the latest driver direct from Intel's web site. That may be what is now installed, but let's see.

    Yeah I just tried to install the latest driver from Intel's website and it brought up the Change/Repair/Remove option screen. That seems to be the one installed.

    Also just a reminder, this wireless connection issue only happens on my apartment's router, and only on my pc. Plenty of other people use my router with no problem whatsoever. Also, I can connect to other routers if I bring my laptop to other places, such as my schools wireless or my parents' wireless.

    Make sure the router is not locking you out via MAC Address filtering. I didn't mention this earlier because I thought you could sometimes connect ("The network works with my pc if I use a wire it, but it almost never does wireless").

    Many of those adapters can be very erratic with the wrong driver so I'm still concerned that we couldn't try the Dell one, but let's take a look at ...

    Please attach a screen shot of the Networks page (don't collapse the Radar, Connection or Signal History) of the Xirrus Wi-Fi Inspector. If you need help with that see TSG Posting a Screenshot. FWIW to take screen shots with Windows 8 or 7 or Vista I prefer to use the built-in Snipping Tool.

    Identify your network if it is not obvious.

    Also show ...

    Open a (black) Command Prompt window:
    Hold the Windows logo key and press r; in the Run box type cmd and click on OK.

    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.

    Yes that is correct, I can sometimes connect to the router wirelessly. Rarely ever though. Usually I can only connect for a short period of time after rebooting the modem and router.

    **not sure if it matters, but the IPCONFIG/ALL command was run after I attempted to conect to my wireless network and it failed.

    The image for the Xirrus screenshot is attached. Hopefully that is what you wanted; I'm not familiar with that software. My wireless network is named "chrispy".

    Also, I'm not sure how to "Make sure the router is not locking you out via MAC Address filtering." Is this done through my router (as in 'routerlogin.net')?

    Yes, MAC Address filtering is a router feature. If you can sometimes connect then you don't have to worry about this.

    Login to the router and disable encryption. If you can connect that way then try WPA-PSK (not WPA2) encryption.

    Changing the encryption type to WPA seems to have let me connect wirelessly! Awesome. Hopefully this isn't just one of the small windows that is allowing me to connect. Hopefully I can from here on out. Thanks a lot!! I'll post back if I encounter the problem again.

    If it's not too much trouble, can you give a brief explanation of why switching to WPA worked? And why other connections that use WPA2 encryption types work for me, but this one doesn't? I'm actually just starting my major in Information Sciences and Technology at college right now, so this issue is interesting to me.

    Thanks for all the help! :)

    Just because, that's why. :D

    I don't know. I think some of the newer wireless adapters or their drivers are not quite right. I was thinking that they weren't handling WPA2 correctly but could still handle WPA. Your latest information says that it must be even more complicated than that. But maybe it's some (many? just a few?) routers that aren't handling WPA2 correctly and some adapters/drivers are more sensitive to the issue than others are.

    Over the last two or three months I've just adopted the practice in cases like this of (a) try laptop manufacturer's driver, (b) try adapter manufacturer's driver, (c) try WPA. And many of these issues seem to be Intel (something something) AGN.

    Good luck with your studies and hope you find some time to help out here as you learn more and more.

    You're welcome. :) If it stays "fixed" you can mark this solved using the [​IMG] button at the upper left of the page or just below the last post.
