    I am suddenly unable to connect to my wireless network, and receive the message "little or no connectivity". All other computers in my apartment, which are all Macbooks, can connect with no difficulty. When I attempt to repair the connection, I'm told that it can't renew my I.P. address. I haven't changed the drivers for my wireless card or anything like that, and it still seems to be working (insofar as it's detecting wireless networks fine). There's no other wireless network in range that I could try connecting to for troubleshooting.

    I have tried resetting the router, and I don't have any network cables.

    Disable encryption on the router and try to connect. Assuming success you can probably re-enable encryption and reconnect. If unsuccessful please show ...

    Start, Run, CMD, OK to open a command prompt:
    (For Vista 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.

    I haven't gotten to remove the encryption yet, as my roommate's the network admin. I'll get him to do it when he has a chance. In the meantime, here's the IP configuration, in case that's helpful absent my having turned off encryption (copied manually, so formatting not preserved):

    Host name: Home
    Primary DNS Suffix:
    Node Type: Unknown
    IP Routing Enabled: No
    WINS Proxy Enabled: No

    Ethernet adapter LAC:

    Media state: Media disconnected
    Description: Broadcom NetXtreme 57xx Gigabit Controller
    Physical address 00-23-3F-57-CD-DB

    Thernet adapter Wireless Network Connection:

    Connection-specific DNS Suffix:
    Description: D-Link AirPlus DWL-G520 Wireless PCI Adapter (rev. B)
    Physical Address: 00-11-95-D4-37-BA
    Dchp Enabled: Yes
    Autoconfiguration Enabled: Yes

    Turning the encryption off didn't help.

    If the below repairs don't get you working, get the latest driver for your D-Link adapter. If you already have the latest use Device Manager to uninstall it; Restart the PC and let Windows find the adapter and reinstall the driver.

    (From a JohnWill post)

    TCP/IP stack repair options for use with Windows XP with SP2 or SP3.

    Start, Run, CMD, OK to open a command prompt.

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

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

    Reboot the machine.

    None of that helped. Is it worth trying to re-set up the network completely? Because that's my current strategy, but I'm leery of trusting my own strategies inasmuch as I'm a moron.

    Update: I've gotten ahold of an ethernet cable, and connected that way - I show up as being connected, but no data is getting through, and when I try to repair the network it's unable to renew my I.P. This means that the problem shouldn't be with my wireless card or its drivers, right?

    The Broadcom NetXtreme 57xx Gigabit Controller may have failed (in some circumstances not really understood by me it can affect wireless also) or you may have an overly protective non-Windows firewall.

    I re-installed Windows, which seems to have solved the problem. Hopefully it won't recur. Thanks for your help.
