Have been having issues with limited connectivity. When running my one computer I do get limited connectivity a couple times a day. When I have both computers on at the same time it's usually limited connectivity all the time. One is running Win 7 and the other XP. I have a WT110 router and a Surfboard modem. They are running on a network and DHCP. They have differing IP addresses which from what I've read is good. Here is the ipconfig for my WIN 7 computer. They are both running wirelessly.

Well, from looking at the IPCONFIG, I think we need to consider a stack reset! Look at all those DNS Servers!

TCP/IP stack repair options for use with Vista or Windows 7.

Start, All Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

In the command prompt window that opens, type type the following commands, each followed by the Enter key:

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.

Alright, completed the stack reset. Here is what I'm looking at with the IPCONFIG now. Immediately after the reboot had limited connectivity for around 10 min.

Check that all your network services are Started:
  • COM+ Event System (for WZC issues)
  • Computer Browser
  • DHCP Client
  • DNS Client
  • Network Connections
  • Network Location Awareness
  • Remote Procedure Call (RPC)
  • Server
  • TCP/IP Netbios helper
  • Wireless Zero Configuration (XP wireless configurations only)
  • WLAN AutoConfig (Vista wireless configurations only)
  • Workstation

Note: You can check the services in Control Panel, Administrative Tools, Services.

All of these services should be started, and their startup type should be automatic (or perhaps manual).

If a service is not running, open it's properties and check the dependencies. Check each of the dependencies and see which one is preventing the service from running. Checking the event log is also a good idea here, there may be clues to what is failing.
