    I have my internet coming from my DSL modem (of course) and running into my wireless router. Once it is in the router I can't get a connection, period. Not even through any of my router's ethernet ports. This wasn't the case until about 3 o'clock yesterday. If I unplug the cable from my wireless router and plug it directly into my computer it runs fine. If I run it through my Micro-Cell tower and into my computer it runs fine. But if I plug it into a router it won't work through Wi-Fi or Ethernet. I have tested the connections of all the ethernet cables I am using. Figuring it had to be a problem with my router (since it was working earlier and the connection only disappears when plugged into it) so I bought another, same problem. What else could it be? PS: I'm using both a MacBook Bro, a PC, a PS3, and a Nintendo 3DS and none get a signal from the wifi. I always keep the PC hardwired through the ethernet ports on the router and use the wireless for everything else. Does anyone have any idea what this could be? It's so frustrating to know that their is a connection, but for some reason it just decides to not work through the router.

    First Name:
    with the old router - whats the make and model
    do a complete power cycle - see below
    if that does not work - you could try doing a factory reset on the router - usually a button or hole in the back - and you need to hold in between 10-30seconds

    if all that fails
    lets see an ipconfig /all from the pc connected by cable to the router and the router connected to the modem - make sure its connected to the correct ports on the router

    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
    From the notepad menu - choose Edit - Copy
    Now go back to the forum - reply and then right click in the reply box and paste


    How to power cycle

    “power cycle” process to reboot or reset the modem/router
    • Switch off all the devices modem, router and computers also unplug their power cables.
    • Wait at least 30 seconds.
    • Plug the power cords back in, but don’t switch them on.
    • First turn on the modem and then wait for a few minutes for it to settle and all the lights to become stable.
    • Next switch on the router (if a seperate device ) and then wait for a few minutes for it to settle and all the lights to become stable.
    • Now turn on your computer, You should now be able to access the Internet.
