Wi-Fi vs Ethernet, which is better?

By now, you are probably aware of the convenience wireless technology promises. This apparently makes WIFI the foremost choice for anyone who plans to get online seamlessly without the hassles of dealing with cable connections, and the wahala of identifying active switch/router ports.

The pertinent question is whether the constant development of IoT apps and wireless technologies will eradicate the use of Ethernet technology IEEE 802.3.

This article will explore the disparity between Ethernet and Wi-Fi connections and also educate you on which connection is suitable for your needs.


WIFI symbol

It is a wireless technology (IEEE 802.11) that connects your device to the internet dispensing the need for a physical wired connection. This technology was introduced in 1999, and it is arguably the more popular type of connection today.


Ethernet cable

An ethernet connection is a means of connecting devices within a Local Area Network (LAN), it enables devices to transmit data over a network following set guidelines. The earliest version of Ethernet was introduced in 1973.


Ethernet uses cables hence it works a little faster than a wireless connection. Wireless connections on the other hand are quite slow and can be hazy (especially when neighboring Wi-Fi devices are operating on the same channels), but they afford you the convenience of usage without any physical connections provided the area of usage is covered by the stipulated range of the emitting device.

This explains why Wi-Fi hotspots provide a more seamless option. Thus the disparity lies between convenience and speed. And maybe security (More on this later).


Internet speed

Wi-Fi was originally on the 802.11g benchmark; with this, connections fell well short of Ethernet which could effortlessly provide 100Mbps -1000Mbps. Thankfully, Wi-Fi has come a long way. Its most recent benchmark of 802.11ac ensures speeds of up to 3,200Mbps giving WIFI a fighting chance against Ethernet technology which now promises speeds of up to 10,000Mbps (10Gbps) on its latest revision IEEE 802.3ae.

The new WIFI Standard IEEE 802.11ay boasts of 20Gbps, and is set to undergo EC resolution in October 2020. This could eliminate the variance in speed between Ethernet and WIFI technologies.


Ethernet’s connection enables constant speed. This means that you’ll experience a steady and fast speed while downloading large files.

Wi-Fi undergoes signal interference due to numerous environmental factors, from physical barriers such as walls, to conflicting radio signals within same bands. The resultant effect, inconsistent performance. This can be mitigated by putting your router in a favorable position in your home/office and manually selecting open channels within your vicinity.

By the way this can be a hassle in a business oriented area such as Wuse II on a business day as wireless devices struggle to send packets on the channels available.

Think of an Ethernet connection as having a direct wired connection to an electricity source with little room for interference. Provided Nepa no take light from the source, you should have constant supply since a wired connection gives little room for interference.

WiFi on the other hand is like gossip. Speak too loud and Mama Ifeoma hears how you think her new shoe is from Karmo market, bend-down-select. Speak in a noisy environment and your counterpart can't hear a thing because I mean, shouting and gossiping aren't exactly synonyms.


WI-FI is an open network which makes it quite unsafe, so you have to use WI-FI networks with certain levels of encryption when transmitting a sensitive data, else with a software like Wireshark and access to your network, real damage can be done.

Data sent over an Ethernet connection can only be reached by devices physically attached to the network, hence no avenue for hacking, data loss, or connection issues.

Well unless rumokoro the rat and his family live within thy walls.


This is the time it takes a packet from a requesting device to travel to its destination. Thus, the longer the latency time, the slower your internet experience. If you want to evade delays and lags while posting data, Ethernet is in many cases the more suitable option. (Many other factors contribute to this)


Many devices in our homes/offices can interfere with WI-FI causing issues such as dropped signals, lower speeds and greater latency. Hence, Ethernet is more dependable with regards to interference provided your cables run through areas void of electromagnetic interference emanating from devices such as fluorescent lights.


WI-FI is the best for portable/remote devices. It's called portable for a reason, hence the reason why you don't see anyone connecting their smart phones to an Ethernet cable.


  • For an everyday connection needs, choose an adequately configured WI-FI.

  • For a gamer who can’t risk an unstable connection choose Ethernet.

  • For stress free HD video streaming choose Ethernet.

  • If radio waves may affect your environment (e.g. medical equipment), you can stick with Ethernet.

  • If you would rather incur lower installation costs, select WIFI.

  • If security is a priority, choose Ethernet.

Ethernet and WI-FI have their positive and negative sides, this is dependent on factors like latency, medium and protocol standard, interference etc. .WI-FI is famous but Ethernet proposes laudable benefits.

To this end, your choice of connection should be based on your needs. Contact Zudera for your network solutions.
