I don't know if this is the right place to ask about this, but maybe someone knows what to do. My husband and I have separate computers and separate addresses. Our computers are not networked together. For years we have been connected, at the same time, to the internet via cable modem and a router. Now we are unable to be connected at the same time.Sometimes it's me and sometimes it's him, but never at the same time and we never know who's going to be connected or when. We've called Comcast and they say the modem is working properly and the problem is the router. The technician, who was here for three hours and replaced the modem couldn't help. All the lights on the router are blinking as they should (we've tried two different routers and they SEEM to be working properly). We are both using Windows XP and all was well until last weekend when we were at the Comcast office to exchange our cable box. While we were there, the woman behind the counter said we only needed one IP address and removed the second one she saw there. Since then, we've each had connection, but never at the same time. I am at a loss as to what to do. Should we buy a new router? Should I call Comcast again and cry or scream? Can someone here give me some suggestions?
I received a few answers in other Forum. One suggested that I do this:
After the first PC connects successfully,then try the following on the PC that does not.
Open a command prompt window and enter these two commands in the following order:
1) ipconfig /release
2) ipconfig /renew
I did that and the ip address did not renew and now I have NO ip address and am not able to connect at all. I should have known better than to mess around with that! We're getting a new router today in hopes that it will help. Any more ideas would be appreciated. Thanks so much in advance for your time...
