Sorry for the last reply , a little under the weather today . My advice for a fix to the limited or no connectivity problem for those of us not schooled in the mysteries of networking is as follows :
1. Open network properties , find IP protocol tab
2. Change IP address from automatic to manuel
3. Enter 10.0.0.1 subnet 255.255.255.0 , hit apply or ok
4. Let computer do a restart and you will now have the same problem
5. Go back to same tab and change back to automatic , hit apply or ok , restart computer and hopefully you are connected { maybe password or whatever security you use will need to be entered again}
I believe this problem is often caused by some settings file getting corrupt or dchp lease expiring on the router or whatever and these steps renews stuff , this is an easy fix and if this doesn't work just keep looking and asking .
