Loss of internet connection

I'm with Time Warner/Road Runner internet service and for no apparent reason, my internet disconnects..2 bottom green lights flash..I call TW..they say they are sending a signal to my modem and my modem is not receiving the signal and that my modem is no good. An hour later, the modem kicks back on with all lights green and everything's fine. Is my modem bad?

Sounds like a switch before the signal gets to your house. Modems usually don't go out intermittently unless they are overheating. Is the modem in a ventilated area where it can get some air? An alternate is to borrow a modem from a friend to test it. Usually one of your niehbors will have the same service and the same modem. I had my surfboard (from comcast) for 5 years and it was solid as a rock, the spotty services was always at the Comcast switches (at the street or the nearest hub.

Hope this helps

Need help, router will not connect. The internet service road runner is working when I plug directly in computer but through the router it won't activate. This router has been working for over a year now...

Try unplugging the power from Road Runner modem and disconnect the computer or router. Then only plug in the power to the router and plug in the power to the modem.

If this does not work, try resetting the modem's config to factory defaults by sticking a paperclip end into the reset button hole in the back while powering it up. hold the buttin in for atleast 15 seconds while the router restarts. then retry the first suggestion.

Sounds like too many people are connecting to the server at one time. You will have to find another service that can handle the amount of people connecting at once.

Linksysy asks for a network key (Wep key or WPA key)

1. Using a computer that is wired to the router, access the router's setup page by typing on the address field of your browser.
2. By default there is no username and password is admin.
3. Once you're in the setup page, click wireless then there is a sub tab there called wireless security.
4. You will find there the wireless key that is enabled in your router.

Not working on my 2nd computer

I am going to assume Vista is the first OS and both machines are windows computers and you are accessing the cable service through a DI-524 wireless router. There are many issues that can relate to your problem. First does your cable provider require you to logon to access the internet. If so, try using each computer individually (with the other one logged off and shutdown) with the existing wireless connection. If this works both machines are configured correctly for the router and the issue appears to be dealing with the logon possibly having it performed by the router if possible. Second if that does not work -- on each machine bring up a command prompt window (Start > All Programs > Accessories > Command Prompt) and type ipconfig and press enter. There may be multiple local area connections but look for one with a 192.168.?.? address on each machine. The first question mark should be the same on both machines and the second different. If this works both machines have connected to the router and we are seeking another issue. If this is not true one machine has a configuration problem and cannot access the wireless router (probably the Windows ZP computer from you description). We will need to diagnose further once you answer the above questions.
