In order to save time and effort it’s important to know router problems from connection problems and be able to check whether the Internet connection in your home or office network is up. Before calling your broadband provider for help try a few tips:
1. For wireless network, verify that you are connected to a correct router which is handling your Wi-Fi network.
2. Restart your computer
3. Turn your router (whether wired or wireless) off for around 30 secs, then plug it back in.
4. For a wired broadband connection remove the Ethernet cable from the back of your router, plug it into your desktop’s or laptop’s Ethernet port and see if the Internet works. If yes, you’re likely to have a router problem, so contact ISP support for assistance.
Use ipconfig to check your network information
You’ll be able to learn a few useful details about your local network from the ipconfig diagnostic utility: enter command prompt mode (Start>Search>cmd) and type
Use ping to check the connection
In the same command prompt mode type
ping 192.168.1.1 (or another default gateway address you got using ipconfig)
The system will attempt exchanging data packets with the router or modem, and if you see a response, your LAN connection is OK.
You can alternatively check your Internet connection from the router’s console, which often include tools for basic diagnostics and troubleshooting of Internet connection problems. Navigate through the ‘System Tools’ tab to ‘Diagnostic’ and then ‘Ping’ to check whether the given host or gateway can be reached.
Pinging google.com or any other domain name is helpful in diagnostics of a DNS problem: if you succeed to ping an external IP address but fail with the domain name, you may solve your DNS issue by changing the DNS server to 126.96.36.199 (Router’s administrative console>Network>WAN).
