Buying Guide

Every feature of a WiFi router is significant, but some are essential, while some can be overlooked. Before buying a WiFi router, you must critically consider some features. Here are the major features you must look for in a WiFi router when choosing one.


The recently manufactured routers are using the 802.11ac wireless standard. Many modern devices are compatible with this standard and give higher speed and better performance. Although the earlier standards, IEEE802.11a, and 802.11b, can also be compatible, it would be best to buy a router with the latest standard and guarantee compatibility with even future devices. 


There are two major frequencies on which internet networks are broadcast. These frequencies are 2.4 GHz and 5 GHz. A dual-band router supports both. This means with a dual-band, you can have two separate networks, one on each band. With this arrangement, you will be placed on any network that gives better performance. If your router has a single band, then you would be stuck in one frequency even if there are too many users on it. Even today, we have tri-band routers that operate on three bands.


There is no doubt speed is critical to all internet users. Whatever you use your internet signal for, you will undoubtedly want high-speed browsing. This becomes more important if you are downloading heavy applications, streaming videos, or making video conferencing. Therefore you must consider the router’s speed before you decide to buy it—the higher the speed, the better the router. 


Imagine watching a movie on your phone and have to stop if you need to go to the restroom. Certainly, everyone wants a router with the maximum coverage. You should be able to move from one part of your home to another without any interruption to the service. Therefore check the range of the router and ensure it is acceptable before you pay for it.

Ethernet port: 

Ethernet connection uses a cable to transmit data. It is generally faster than a wireless connection and more stable and reliable. Different routers come with a different number of Ethernet ports. You must check the availability of the Ethernet connectivity, the number, and the speed before choosing a WiFi router.

FAQ: Most Common Questions Answered About 100Mbps Router

1. Is it okay to buy an older router that supports 100Mbps speed?

Yes, of course. In this way, you can save a lot of money as long as it handles your 100Mbps Internet speed plan. Indeed, you don’t need to buy any modern router with the greatest features and technologies unless you need them.  

However, make sure the older router supports at least 802.11ac wireless standard and offers dual-band frequency. That’s because most modern routers are WiFI-5 compatible; going with the older wireless standards, such as 802.11n and 802.11g, would not be a smart decision even though they handle your 100Mbps plan. 

2. A 100Mbps router can cover my entire 2,000 square feet home?

If you expect it from any budget router, then my answer would be no. However, any best router under $100 might give you coverage of up to 2,000 square feet, theoretically. For example, The Speedefy AC2100 Smart WIFI Router. It can cover around 2,500 sq. ft. 

Moreover, I suggest people don’t buy long-range routers only for the sake of coverage and range. It is because even expensive routers face speeds dropping issues at the edges of that range. Instead, buy any cheap router and add an affordable WIFI extender to it to get the proper range throughout your house. 

3. Should I buy a WIFI 6 router for my 100Mbps internet plan? 

Why not? As I said earlier, most smart WiFI devices support the WIFI 6 wireless standard these days. Since it is known for working flawlessly across both the 5GHz and 2.4GHz bands, it eliminates congested and busy network issues, and you’ll see a significantly faster performance.

4. Are these routers compatible with Verizon’s 100Mbps internet plan?
