How To Troubleshoot Slow Internet and Network Connections
Published Jun 20, 2023
This video will demonstrate the troubleshooting procedure for slow Internet and Network Connections.
Here’s how to get the best from your Internet connection. First, check your connection speed using an online test and compare the result to the speed advertised by your provider.
Remember that throughput is shared between all the devices on your network. Check what’s running on all of your devices and avoid downloading large files while testing, streaming video, or playing online games.
If the result is too slow, first try restarting your network equipment and devices and test again. For both DSL and cable, check that your modem supports the speeds offered by your provider.
You may have to update the firmware or upgrade to a newer model to get the best speeds. Also, check that your devices and any other networking equipment support the speed of your connection.
For example, if you share a 100-Mbit connection using an 802.11 Wi-Fi, the speed will be limited to 54 Mbits per second. If you don’t secure your wireless network correctly, people may connect uninvited.
Use strong encryption, disable WPS, and change the SSID password from the default. Avoid positioning wireless access points on the floor or inside cabinets, as this can reduce range, Interference in the 2.4 GHz band from cordless phones, baby monitors, and other devices can also cause issues.
Changing the Wi-Fi channel may also improve speeds. Use a Wi-Fi analyzer app to see which channels are least used or experiment by changing the channel and testing.
For both wired and wireless connections check that your network card drivers are up to date. For help finding or updating drivers, search dell.com/supportvideo.
