Windows 7 internet connection problems

[dspen1111]

Hello,
I have a toshiba laptop with Vista and a Compaq laptop with windows 7 connected to a Compaq 6100 PC with XP, through a Dlink 601 N router. Both have been working great until this week when the Compaq laptop with windows 7 suddenly quit connecting to the internet. It says it is connected to the network, but with no internet connectivity. The troubleshooter cannot find anything and I have turned the cable modem (roadrunner) and router off and on multiple times to no avail. I have disabled and enabled the network multiple times to no avail. I went to command prompt to release and renew the IP address and get error messages on the renew...no operation can be performed on wireless network connection 2 while it has its media disconnected, and, an error occurred while renewing the interface wireless network connection: unable to contact your DHCP server. Any advice?

Were you in the Compaq laptop when you had the message that the media was disconnected? Limited connection is normally due to the wrong security key being used - have you checked that yours is the same as the other computers and if necessary, copied straight from the router's settings page?

yes to all; it just has the yellow triangle at the bottom and I can't even connect to the neighbors wireless network outside my own network. It has been connected and used for months, and all of a sudden for no reason that I know of no longer connects to anything.

Sorry but where is this yellow triangle? If in Device Manager, it needs a driver update. If it's somewhere else, please post where you're seeing it.

at the bottom right, where it should show that it is connected and active; it shows a few power bars (like on a cell phone, etc) with the yellow triangle signaling that there is a problem.

I go back to my suggestion about the security key if you're connected but able to go no further.

i'd try to delete the connection from n/w n sharing center and then start fresh again.. might help
