How to Ping a Router Through a Wireless Networkby Christopher Williams
Ping is a tool built into most computer operating systems and networks which allows users or administrators to test connectivity between two computers or a router. The ping tool sends a series of small data packets to an IP address designated by the user and requests a response to be sent in return. The tool then displays results showing whether the response was received and how quickly. Ping works the same way over any IP network, regardless of whether it is wired or wireless, so these instructions to ping a router to test connectivity will work in either case.
Open a command prompt window. The command prompt can be found in the Start menu or you can type "cmd.exe" in the search programs bar.
Type "ping (IP)" in the command prompt window, where (IP) is replaced by the IP address of a remote computer or your router. For example, if your router's IP address is 192.168.1.1, then type "ping 192.168.1.1" and press "Enter."
Observe the results reported by the ping tool on subsequent lines in the command prompt window as the program executes. If you see affirmative references to packets received, then your connection to remote computer or router is good. If the request times out, the connection may be down, or the remote computer or your router may be configured not to respond to ping requests.
