I am network challenged .... Let's just get that out of the way. So brief and dumbed down answers would be greatly appreciated.
I have a linksys wireless router and assorted computers throughout the house. About a week ago, something happened and only one computer can connect at a time to the internet. It can be any of the three but the first one is the only one who gets access and can actually touch the web. No configuration changes within the house were made that we are aware of.
ipconfig shows a valid IP address, gateway host, DHCP server, and three DNS servers. Network is dc.dc.cox.net. But DNS is not available.
NSLOOKUP results with
DNS request timed out
default servers not available
default server unknown.
The other computers show (thru the linksys interface) that is is connected to the internet but no access point is available. bytes received and transmitted are way above zero within a few minutes.
cox network support is real good about saying "It's not our service" but provide no answers how to eliminate any other issues.
What do i need to check with the linksys router to verify I am authorized more than one connection? not sure if the service is limited to only one connection or not.
Any assistance would be appreciated.
