3) and at my house , i must on router first , if not , i must restart my com because it will keep connect with limited access
I use to have this problem and went to do some research on my own, normally it is after installing Windows XP Service Pack 2 and "This connection has limited or no connectivity" start to appear, the cause of the problem and solution may varied, it normally involves a bug in Service Pack 2 of Windows XP dealing with a loss of network connectivity for workstations that use Microsoft’s L2TP-based virtual private networking (VPN) client to connect to servers that are connected to NAT-based networks. However, this bug seems to appear in situations that are not associated with VPNs either.
I came down to a few solution which you can take as reference, microsoft release a patch that adress to this problem, patch ID is
KB884020, I tried but don't solve my problem.
Use
WinSockFix, it is a program that is create to reset your TCP/IP. The Winsockfix Utility will:
· Detect your current Operating System
· Release the IP address, taking you "Offline"
· Reset the TCP stack using Netsh.exe (Windows XP only)
· Delete the current Registry TCP and Winsock Values
· Import new "Working" Registry Values
· Backup any Current "Hosts" file
· Replace the "Hosts" file with a default one
· Reboot the Computer
I apply this patch and it solve my problem on my notebook.
And also when I switch my LAN cable from my desktop to my laptop, the problem will come back which apply this patch also do not help, if this happen you can try to reset your rounter and let it assign IP address again, you can just go to your rounter and pull off the power cable and plug back, this is reset your rounter.
