Internet Connection Problems

If you are encountering an internet failure, having difficulty connecting, or experiencing a slow or unstable connection, here are some steps to take in order to restore your internet connection.


Diagnose a Connection Problem

When you encounter an internet connection problem, it's important to check your device(s) (i.e. PC, Tablet, Smartphone, etc.) and your internet provider's box for any apparent issues.

Connections

Check your connections (i.e. telephone, USB, power supply, modem cables, etc.) to ensure that they are well connected. Also, check if your modem flashes to indicate a connection. These instructions can be found in the manual from your internet service provider.


If your internet connection is sourced from a telephone cable, you should also slowly remove and replace the phone plug. It's possible that poor contact with the metallic receptors is impacting the internet connection. The plug must be pushed in all of the way to ensure a good connection.

Reboot

You could try rebooting your internet box to remedy the problem. If this doesn't work, try restarting the device to which you're attempting to connect.

Software

It is important to test other applications that use an internet connection (i.e. e-mail, instant messagers, games, etc.). This will help determine if the problem is with the Internet as a whole or only a few applications.


To confirm that the problem does not come from the DNS, take the following steps. If you are under Windows 10, 8, or 7, try typing [Windows + R], then
cmd
, and finally
ping 8.8.8.8
.

Check your IP address and your network settings. You can find this in your ISP's manual, but generally you can obtain an IP address automatically by going to Control Panel > Networks > Connection Properties > TCP / IP Settings on your computer.

If you are using a WiFi (wireless) connection, check that you can connect to the modem. If you can't, there is a problem with the connection to your WiFi network. To correct this, try to reinstall your drivers and restart the WiFi. To check if the problem is with your WiFi, try to connect to your modem using an ethernet cable.

System

There are several systems checks that can be completed to debug your internet connection. First, check your firewall settings. Port 80, your internet browser, and any other applications requiring the internet should not be blocked.


Second, run an antivirus and antispyware scan if your connection is particularly slow or if you encounter problems without any real explanation. A virus could be occupying your bandwidth without your knowledge.

Next, you can try to re-install the modem and/or your ISP's software. Ensure you have installed the latest updates to your operating software. Sometimes software updates include bug fixes that may be causing your computer to perform poorly or to crash.

Lastly, try to repair Windows if you think that system files may have been corrupted by your latest modifications or updates.

Network

You can also choose to manually create an internet connection without going through the ISP's software. This can sometimes unblock the issue, if the problem comes from the latest versions of your ISP software.


If you can connect to the Internet, but find the connection slow, there are tools online to check your connection speed. Connection speed problems could be the fault of the ISP or a particular website.

Contact your internet service provider to ensure there is not a general failure that is impacting your connection. If you are able to connect elsewhere, you can also consult online forums to see if there are any network problems or if it is isolated to your device.

If the problem is isolated, try moving the modem to another place. If this does not work, try to change the modem or cable to see if there is a hardware problem. Contact your ISP you believe there is a hardware issue to get the required replacement equipment.
