5 Problems of Using WiFi to Transfer Data

By on

Most of us are guilty of favouring wireless internet ahead of a wired Ethernet connection for the convenience that it offers, but is it impacting the speeds that you are accessing? Whilst it might be minimal for basic navigation, this can play a large role in data transfer speeds.

Reduced Wireless Connection Speeds

You will notice a variation In the speeds that you are able to access via a wireless versus wired Ethernet connection, often minimal to the extent where you don’t value the difference significantly if sat directly next to the router.

This can however become a more substantial difference when range is stretched as a weaker signal is reflected in the connection that you are able to achieve. Whilst your router will be accessing the speeds you pay for, that doesn’t necessarily mean that is what you will access wirelessly.

Wireless Interference 

Latency represents the time required for packets of data to transfer between your device to your router initially, then onwards to your internet service providers servers and through to the destination to retrieve the data.

Whilst you may have a great download and upload speed, that won’t overcome delays in communicating with the necessary servers in order to transfer the data packets.

Ethernet connections provider a better latency as they are directly wired to your router, opposed to wirelessly sending the packet data. This is due to the potential disruption in wireless signal and extensive ranges at which you connect via a wireless connection.


Ethernet provides a faster, more reliable connection for data transfer

Reliability and Connection Constancy 

An Ethernet connection is very reliable and issues rarely present, often related to a loose or damaged cable which can be quickly identified and corrected. A wireless connection however is much more temperamental and reliant upon a number of factors.

Hardware Limitations

Whilst internet hardware is continuing to evolve, there remains a substantial difference between the quality of Ethernet cables and your typical residential router. Ethernet cables tend to be better value when compared against the achievable speeds against a router.

Whilst a router can compete to achieve high speeds like an Ethernet connection, you can often find that this advanced specification of router is more expensive to purchase.

Security Risks to Your Connection

Wireless internet relies on security credentials in order to connect to the router. Even if your router supports a modern security solution such as WPA2-PSK, it is not always a risk-free guarantee that your connection won’t be breached.

Ethernet connections do not have this problem as the ability to connect is warranted only by a wire from the device back to the router which you control.

Ethernet or Wireless?

As we rely on a wireless connection for many of our devices now that don’t support Ethernet such as mobile phones and tablets, they are essential to most households. It therefore makes sense to have a wireless connection present.


You can however take advantage of Ethernet connections by plugging your static devices such as desktops and stationary laptops into a wired connection to the router that will better serve those particular devices, or achieve the best of both worlds by utilising our Cambrionix EtherSync.
