    Can anyone assist me with accessing the internet? My computer stopped connecting a few days ago. It had been working great until then. I have two other computers in the same wireless environment and they are working great. I've done all the preliminary checks and had all the settings checked by Comcast (my internet provider) but they were not able to evaluate the problem without cost. I've been unemployed for the last two years so I need to find another option to correct this issue. Every time I attempt to connect, windows says that they are unable to renew the IP address. Limited or no connectivity is shown. I've also noticed that If I leave the home where I'm trying to connect, I'm able to connect to outside sources like Wayport or any other network without any problem. My router is a Linksys Model #WRT320N. It's working just fine with the other computers in the house. Please let me know if you can help. I tried cleaning out all my "preferred networks" in the wireless Network Connection Properties but that didn't work either. Your help would be much appreciated.

    sould you post an ipconfig /all from one of the working PCs and also from the none working PC , you will need to copy the information onto a working PC
    Please make sure we know which is the working PC

    Does your network have any wireless security enabled - it would be worth logging into the router and then removing the security and see if you can now connect the non-working PC


    ------------------------------------------------------------------------
    ipconfig /all
    If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here

    We would like to see the results from ipconfig /all post back the results in a reply here

    Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):

    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 > network.txt & network.txt

    It will export the results to notepad and then automatically open notepad.

    Now all you need to do is copy and paste those results to a reply here
    to do that:
    From the notepad menu - choose Edit - Select all
    all the text will be highlighted
    Next
    From the notepad menu - choose Edit - Copy
    Now go back to the forum - reply and then right click in the reply box and paste

    Below is the ping info. How does this help? There is no wireless security enabled at this time. Would a scan in "Network Diagnostics" be useful. I'm wondering if the DHCP server may be involved with this issue, perhaps it's not working properly??

    Top suspect is a mis-configured or corrupted non-Windows firewall. What one do, or did, you have?

    Not sure what the windows firewall is and don't know how to figure that out but I know that it's turned off. What I've found recently very unusual is that it is working in some rooms of the house (didn't know before) but not working in the rooms that I normally use it. (wouldn't you know).
    This may change the picture somewhat. Any suggestions??

    Norton Security was installed for some time. It was provided by Comcast although I have uninstalled it recently to try an correct the problem.

    Norton is probably not the problem, since you are working in some locations, but it doesn't hurt to run the Norton Removal Tool.

    For a "good" room and a "bad" room please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector.

    What Xirrus Wi-Fi Inspector is saying while connected (good room):

    This is the only thing that will paste when I select print screen:
    Adapter Name: Broadcom 802.11b/g WLAN

    The rest of the info, I've written out:

    Signal is -69
    Frequency is: 2412
    Network Type: Access Point
    Network node: 802.11n
    Cisco-Linksys

    When the test is done in the bad room (actually closer to the router & modem) the only thing that changed was the signal. It changed to -48

    How does this help?

    How about a mismatch between 802.11b/g and 802.11n ?

    I noticed that but I don't know what it means. Would you clarify? Do I need to fix something?
