Are you using ADSL broadband, but your connection speed is slower than dial-up? Sometimes, you can’t even access the Internet. What should you do to achieve a faster and more reliable Internet connection?
First, make sure to update your antivirus software, anti-spyware tools, and configure your firewall. Next, run a scan for viruses and spyware. If your computer is infected with these programs, your broadband connection may be very slow, potentially even slower than a dial-up connection! When one computer on the network is infected, the entire network can be affected.
After ensuring that your PC is “clean“, use the ping command to “test” the quality of your network connection. You can go to Start -> Run, type command /k ipconfig, and press Enter. The results box will display your network settings, including your computer’s IP address (formatted as x.x.x.x, where x is a value from 0 to 255). In the command prompt, type: ping ipaddress, where ipaddress is the address from the “IPAddress” displayed earlier, and press Enter. You will see a list of packet statistics over time. If the ping fails with “Destination host unreachable,” the issue is likely with your network card or the connections between your PC and the ADSL router/modem. Type exit and press Enter to close the command window.
If you cannot ping, it is likely that the router, modem, or some connecting device is causing the problem. You should check the power supply to the modem, inspect the plug connections, and review all connection points. Wait a few minutes, restart your computer, and the issue may resolve itself.
Another quick and inexpensive method is to replace the cable. Old or damaged cables, possibly chewed by mice, can also cause issues.
If all computers on the network cannot connect simultaneously, and your computer is free of any viruses or malware, then the issue may not be related to Windows, your PC hardware, cables, or Wi-Fi connections. However, if only one computer cannot access the network, it is likely due to one of the aforementioned causes.
If you are using a Wi-Fi network, check the strength of the connection signal (most wireless network cards have an icon in the system tray). If the signal is weak, try removing some obstacles like: potted plants, fish tanks, or CD cases… This can help your wireless network card receive a stronger signal.
Finally, if everything seems to be working well, but you still cannot connect to the Internet, it is best to call the technical support department of your Internet Service Provider (ISP). If the ISP did not provide the modem or router, you may contact the store where you purchased these devices for consultation and troubleshooting.
