    Hoping someone can help me connect to my new wifi!

    A few days ago, I just had comcast cable/internet/home phone installed, all run through a modem/router combo. (I'll try to post some more specific details below). So, TV and phone are working great. And actually even the internet is working great. I just can't connect MY laptop to the internet. I can connect my iPhone and Kindle Fire w/o difficulty. And if I plug into the ethernet cable, I can get the laptop to go the internet. But when I connect to my wifi connection, I end up with only a local connection. On a side note, the first time I tried to connect to the signal, my computer asked me to set up a profile for it (WLAN profile I think). And I did, stupidly. I vaguely remember having a problem with that in the past, but I had tech support at my college that fixed it.

    I have restarted both the modem/router and my computer multiple times. I have tried to repair the connection with Windows. I have tried tech support with comcast, but they keep referring me to the computer manufacturer. There is an unsecured signal nearby I CAN connect to (tried out of curiosity to make sure it WASN'T the laptop), but I don't want to pirate, so instead I stay tethered to my 2ft ethernet cable. I have searched google and reddit to no avail. I do not claim to be tech savvy, but I can follow directions pretty well (just be specific step-by-step). Last night out of desperation I tried the Geek Squad online chat to help, but I can't stomach $80 for what I'm sure is a simple problem.

    So on to details:
    Router/modem combo--SMC network
    Model number: SMCD3GNV
    Encryption: TKIP+AES

    Laptop--Sony VAIO (2007ish) running Windows Vista

    Can anyone help?

    Delete the wireless profile and try again to connect. In Vista I think from the Network and Sharing Center you click on "Manage wireless network" to get to the list of profiles.

    If that doesn't work ...

    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.

    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.

    Tried deleting the profile without luck.

    The screenshot of the Xirrus wifi inspector is attached below.

    And here's the last bit from the command window.

    Sorry it took so long to reply, I'm trying to fix this while working around my 12 hour shifts. I have another tomorrow morning, so it may tomorrow evening before I reply to another response. But TIA for your help!

    That signal is so weak it is amazing that you get any connection at all. Assuming that the router is OK ...

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

    If the wireless card is easily accessible through a cover on the laptop's bottom remove and firmly and carefully replace it several times in case of looseness or corrosion. Make sure the antenna leads are secure. (Top suspect in my mind is loose antenna leads.)

    I know the signal shows as weak, but when you actually connect to it it has full strength (5/5 bars). I'll check on the software and wireless card when I get home and let you know.

    Downloaded a few updates to the software and restarted the computer, still only a local connection. And I don't know what I'm looking for in a wireless card, especially if I have to removed the bottom cover. As for the router being good, seeing as all other devices connect without difficulty and have full signal, it has to be my computer.

    Well, I guess don't worry about it. Finally broke down and paid someone $80 to fix it. But thanks for the help.
