Does A Router Affect Ethernet Speed?

Does a router affect Ethernet speed? Yes, it does. 

But for a router to significantly affect your Ethernet speed, it involves a couple of factors. We take a look at routers and Ethernet connections in this post. 

Here’s How Routers Affect Ethernet Speed

Does A Router Affect Ethernet Speed

Old Router

Older routers can significantly reduce the Ethernet speed because of the lagging and taking longer to load.

Unfortunately, this is a common issue in older homes where the network still operates on outdated routers, most notably 802.11g. 11g router is only capable of supporting 54mbps, which is not enough for modern internet usage. 

11n routers are a bit better, supporting up to 300mbps of bandwidth.

Although 11n routers are much better than 11g routers, if you need the best routers for the fastest Ethernet speed, consider getting the 11ac routers, the best on the market. 

Outdated Router Cables

An old or an outdated router cable can also affect your Ethernet speed, irrespective of the internet connection plans and speed. Older routers will naturally have cables that do not meet the current standards. 

For instance, Cat5 or Category 5 Ethernet cables are only capable of supporting 100mbps of internet speeds. So even if you bump up your plans to 1000mbps, if your router cable is old, it will not be compatible. 

Similarly, a cheaper router will also reduce the Ethernet speed due to the same reason as cable incompatibility.

In addition, a low-quality router can also crash and reboot occasionally, which can affect the Ethernet speed. 

The Number Of Ports And Devices Connected

Generally, most routers come with multiple Ethernet ports to accommodate several PCs. If all the Ethernet ports are used simultaneously, it puts a strain on the router. Substandard routers are infamous for this problem. 

For Wi-Fi routers, the number of devices connected to it can affect the speed as well.  

On the other hand, high-end routers come with individual subnet for each Ethernet port, so the speed does not get affected. In addition, these types of routers allow you to make several adjustments and personalize your Ethernet network. 

Will A Better Router Increase Ethernet Speed?

Yes. A better, meaning an updated router, can significantly increase Ethernet speed. The latest routers on the market have up-to-date configurations – both hardware and software. 

There is a lot of difference between a single-band, dual-band, and tri-band router, but you can expect better speed, control, and coverage with a new one. 

What Routers Are Good For Ethernet Speed?

In this section, we recommend some of the best routers that are great for Ethernet speed.

Wired routers

If you are lucky to have Ethernet cabling at home, you want to look for routers that deliver anywhere from 1000mbps to 1gbps of data speed. In addition, look for a router with several LAN ports and WLAN ports if you use ISP connections. 

Furthermore, a wired router with a hardware firewall system is essential since you want to keep your connections safe. 

Our top choice for wired routers is the TP-Link Safestream Wired Router.

This router has the best combination of performance and premium features, which you will appreciate. In addition to great data transfer speed and multiple ports, this wired router has top-class security features. 

Wireless routers

If your preference is a wireless connection, a Wi-Fi 5 should suffice for a home network. Most home or even smaller office networks run on 802.11ac Wi-Fi 5 so, investing in a Wi-Fi 6 may be unnecessary.

A wireless router that has a great combination of features and pricing is the Asus RT-AC88U.

This high-performance wireless router has top features, so you will have no issues performing heavy-duty gaming and live streaming.  

Of course, if you have a lot of Wi-Fi 6 devices on your network, you will benefit more from a Wi-Fi 6 router. 

In this case, you can check out the Netgear Nighthawk RAXE500. With top of 6GHz band and security software, you can experience the best Ethernet speeds from a wireless router. 


Regardless of the size of the network, routers are a critical component for overall performance. It is not just the network’s speed, but the ease with which you can control its performance also has a lot to do with the network. 

If you are experiencing a slugging Ethernet speed and you haven’t checked your router in a while, you might want to take a look at it. Identify the router’s model, the number of devices connected to it, and you’ll figure out the problem in no time!
