When to Use Ethernet Cables to Connect to a Wireless Router?

Connecting to the Internet using an Ethernet cable may seem old-fashioned to some – like a return to the last century, but it’s not because it still has its benefits. Although it is used much less than Wi-Fi, there are definitely several situations when this way of connecting devices makes sense.

 Here are some of them:

  • When You Need Minimal Latency – Latency is the time it takes for data from your computer to reach its desired destination and then return to your device.  Latency (aka delay or ping) can be higher or lower. If you use an Ethernet cable to connect to the Internet, it’s significantly lower compared to a Wi-Fi connection. One of the situations where you need minimal latency is playing online games. Gamers are well aware of how embarrassing a situation can be when it comes to being late when playing a game online. In addition to playing online games, we also recommend using an Ethernet cable for streaming and online conferencing. 
  • When You Want a Higher Level of Security – Connecting to the Internet with an ethernet cable is much safer than a wireless connection. It allows you to physically connect to your network equipment.
  • When You Need Max Speed – If you want to test your internet speed, we recommend that you use Ethernet cables to connect to the router (Wi-Fi does not deliver full internet speed for several reasons – you may be too far away from the router, there may be obstacles and walls between your router and connected devices, etc.)
  • When You Have Problems with Wi-Fi – Although you use Wi-Fi every day, it is certainly very useful to always have one spare Ethernet cable in your home as it can be useful in case you have some problems with your Wi-Fi connection – until you fix the Wi-Fi problem, connecting with an ethernet cable will allow you to stay connected.
  • When Your Router is Physically Damaged – You may have dealt with this issue in the past. Any kind of antenna damage or software malfunction may prevent you from using Wi-Fi. Until you replace the part or buy a new router, Ethernet cables will allow you to connect.
