5 years old box implies, to me, XP.
So is this Windows XP?
Bunch of things come to mind, mostly related to "...but if I shut it down for and hour or more the same thing happens. I can't get on line with a message that I have limmited or no connectivity. It seems to have something to do with loosing my network key and IP address"
Loss of DHCP connection between the computer and the router
> check Network properties of the TCP/IP - does it have automatic DHCP, it should, and the DHCP server should be your internal IP of the router. Probably something like 192.168.0.1 or 192.168.1.1.
Loss of DNS connections between the router and the ISP servers
> make sure the correct DNS servers of RoadRunner or, much better, OpenDNS servers are listed in the router (220.127.116.11 and 18.104.22.168)
> make sure the same DNS servers are listed in the TCP/IP properties
Router timeout if idle (probably no issue here since the desktop is ok)
> check, in the router interface, if there is something about timeout. Words such as stay connected always, etc. It could be when the router times out all connections are lost.
If you use a firewall of any kind, make sure that both the router and the DNS servers are set as trusted. If you don't use a firewall you should
I don't know what you mean by the "network key". Do you mean the password your ISP gave you or do you mean the key needed between your computer and the router for the security of the wireless connection?
> recheck the properties of the wireless connection are ok, including all above
When you do get connected to the router, collect the information from the computer which might help someone here to help you. Like this:
Start, Run, type cmd, press enter
on the black window, type "ipconfig /all" without the quotes and with a space before /all, and press enter. Copy what you see and paste here.
When things are ok, you should be able to see your internal IP, as well as the data about DHCP and DNS I'm suggesting we need to see.
When things are broken, the IP address will be 169.x.x.x which Windows issues if it can't renew your address.
