    I too had a problem when we re-modeled the computer room. I simply unplugged the power supply and left all other cables intact. Since we don't usually use the PC that the router and modem are attached to, rather we use our laptops, I simply re-plugged everything into a portable power strip and we did fine for the week that the room was disassembled.

    When I moved the PC back into the room, I simply plugged in the power. Nothing. No internet to the PC, no wireless. I have tried resetting all boxes, changing out ethernet cables, uninstalling the router and reinstalling, calling AT&T (short of their 140.00 service call which I refuse) and being mindful of switching the modem from PPOE to bridged. I finally bought a new router (which was stupid, I've never heard of a router going bad) and even that didn't help. when I had this problem last year, it ended being the modem and once they replaced it, I didn't have any other problems until now. My modem works fine as long as it's hardwired into the PC.

    Any suggestions would be greatly appreciated. I've never had this problem with any other service provider besides at&t. I'm so over it!

    Even though it appears you're having the same problem, please start a new thread when you have a new issue. It's very difficult to keep two problems straight and who's working on what in a single thread.

    I've created a new thread for your issue here.

    Note: You will need to post complete details of your configuration and your specific issue in this new thread for us to help you.

    Thanks for your cooperation.

    Please supply the following info, exact make and models of the equipment please.

    Name of your ISP (Internet Service Provider).
    Make and exact model of the broadband modem.
    Make and exact model and hardware version of the router (if a separate unit).
    Make and exact model and hardware version of any other network equipment, like a repeater, a booster, hi-gain antenna, etc.
    Model numbers can usually be obtained from the label on the device.
    Connection type, wired or wireless.
    If wireless, encryption used, (none, WEP, WPA, or WPA2)
    Version and patch level of Windows on all affected machines, i.e. XP (Home or Pro), SP1-SP2-SP3, Vista (Home, Business, Ultimate), etc.
    The Internet Browser in use, IE, Firefox, Opera, etc.




    Please give an exact description of your problem symptoms, including the exact text of any error messages.



    • Have you tried to do a system restore to before the problem occurred?
    • If you're using a wireless connection, have you tried a direct connection with a cable to see if that changes the symptoms?
    • For wireless issues, have you disabled all encryption on the router to see if you can connect that way?
    • For wireless connection issues, have you removed all the stored wireless network profiles and then searched for the network?
    • For wireless laptops, have you made SURE the wireless switch is on?
    • For wired connection issues, have you booted in Safe Mode with Networking to see if that changes the symptoms?
    • Have you connected directly to the broadband modem to see if this is a router or modem/ISP issue?
    • If there are other computers on the same network, are they experiencing the same issue, or do they function normally?





    On any affected computer, I'd also like to see this:

    Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

    Type the following commands on separate lines, following each one with the Enter key:

    PING 74.125.45.100

    PING yahoo.com

    NBTSTAT -n

    IPCONFIG /ALL

    Right click in the command window and choose Select All, then hit Enter.
    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.
