How Ethernet Cable Length Affects Network Speed
Ethernet cables often deliver faster speeds than Wi-Fi, but their performance is not unlimited. The length of the cable and the type of cable used both play a role in determining the actual speed you experience.
Why Cable Length Matters

As an Ethernet cable gets longer, the signal can degrade, which may lead to lower speeds. The exact length at which speeds drop depends on the cable category and the network standards in use. However, the source material does not specify a particular threshold.
Cable Type Also Plays a Role
Different Ethernet cable types have different capabilities. The type of cable, along with its length, influences whether you can achieve the maximum speed your network supports. Again, specific details about which types perform best at which lengths are not provided in the source.
Ethernet vs. Wi-Fi
In many cases, a wired Ethernet connection provides faster speeds than Wi-Fi. But this advantage can be affected by the length and type of cable you use. For optimal performance, both factors should be considered.
