Windows Network Troubleshooting: Tips and Techniques - Limited Connectivity
(Page 3 of 4 )
The message signaling this issue is “Local Area Connection: This Connection has limited or no connectivity.”
This is a trickier type of LAN connection problem, with many possible root causes. To troubleshoot, follow the diagnostic flow chart below.
For wired and wireless LAN connections:
You need to first check the network cable to see if it is disconnected (for wireless, check to see if the antenna is on or the wireless configuration is okay). Sometimes this is the cause, and you can refer to the troubleshooting procedure discussed above. If you are sure that the network connection is okay, there could be problem with your router configuration. The following is the “wrong router configuration troubleshooting” procedure:
Step 1: Double check to make sure this is a real error. Sometimes this error can appear despite there being no problem at all. A simple way to check is to open your browser to see if you can connect to the Internet. If you cannot connect, then proceed to step 2.
Step 2: Go to Start -> Run -> CMD, and then at the DOS command prompt, type and enter:
tracert yahoo.com
This command will trace the connections starting from your computer all the way to the computer where yahoo.com has been hosted, to find out where the connection has been broken.
The purpose of doing this test is to find out whether or not your router is working. If it is working, it should not give a “timeout” result, but instead be able to pass a packet starting from your computer, to the router, and then to your ISP's computers, and finally to the hosting computers of the website.
Below is an example of a “working” router:
Based on the above results, the router with IP: 192.168.1.1 passed the packet at ~2ms, and then it was received by the ISP's IP around 22ms later. This means that the broken connection is not caused by the router.
