    Over the past couple of days my wifi has been disconnecting, and when I mouse over the network icon it says "local only" I know its not my laptop because my wife's laptop does the same thing at the same time. So this leads me to believe its the router.. I didnt change any settings on the router though so i dont know why all of a sudden it takes a crap..

    any ideas?? oh and I cant just "reset my router" because for some reason the reset button in the back doesnt press or do anything. I have a Linksys WRT54G

    Resetting the router is as simple as pulling the plug. If you want to reset it to factory defaults, you can do that on the internal configuration menus for the router.

    Some things you can try here.

    1. For wireless connections, change the channel on the router, I like channels 1, 6, and 11 in the US.
    2. For wireless connections, try moving either the wireless router/AP or the wireless computer. Even a couple of feet will sometimes make a big difference.
    3. Update the firmware to the latest version available on the manufacturer's site.
    4. Reset the router to factory defaults and reconfigure.
    5. Update the network drivers (wired and wireless) on your computer to the latest available.

    Many times these measures will resolve a lot of intermittent issues.

    Let's see this for the working laptop, then for one of the non-working ones.


    Hold the Windows key and press R, then type CMD to open a command prompt:

    In the command prompt window that opens, type 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

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

    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

    Well, it sure looks like both have a good connection to the Internet. Any particular symptoms when it does and doesn't work?

    when my wife wakes her laptop up, it wont connect, she has to "repair" it each time, and then it works. Now doesnt repairing assign a new IP address? Could there be conflicting IPs?

    Repair duplicate IP address on network issue.

    1. Turn off everything on the network, ALL the machines and any other network device like network printers and NAS drives.
    2. Turn off the router and modem.
    3. Turn on the modem, wait for a steady data light.
    4. Turn on the router, wait two minutes.
    5. Turn on the network devices and computers, one at a time.

    This issue is usually caused by resetting a router without resetting all the network connected devices.

    Another issue that will cause duplicate IP addresses is assigning static IP addresses to devices that conflict with the router's DHCP address range. If you require static IP addressed devices on the network, they should be configured to be in the same subnet but outside the address range defined for the DHCP server.

    Networking doesn't always work after a computer is awakened from Standby/Sleep/Hibernate. Many times nothing short of a reboot will work. Attempted fixes are item #s 3, 4 and 5 in John's post # 4
