Features to pay attention to when buying a WiFi router
However, the problem may occur when there are too many devices connected to that router. The network may be slow or may not reach other areas of your home. In this article, let’s learn about the important features to pay attention to when buying a router.
1. Standard WiFi router
In line with the trend of technology development, WiFi router manufacturers have been continuously launching new and stronger wireless standards. When considering buying a WiFi router, the first thing you need to check is the WiFi standard it supports. Regular WiFi routers will probably support 802.11b or 802.11g, newer versions support up to 802.11n. Theoretically, the WiFi router that supports 802.11n will allow you to transfer data at 600mbps (although the speed drops a lot in real situations).
The latest WiFi standard, 802.11ac allows transfer rates up to 1.3Gbps. Thanks to this transfer rate, users can connect more devices with high data transfer rate. However, the standard 802.11ac WiFi router is very expensive, much more expensive than the 802.11n router and only a handful of compatible phones and computers.
2. Wireless frequency router – Single or dual band?
All wireless routers operate with two different frequencies – 2.5 GHz and 5 GHz. The main differences between these two frequencies are noise and range. The 5GHz band is less prone to interference, and provides a faster connection. 5GHz is a better option if you determine to connect multiple devices or have overlapping networks in your area. Meanwhile, the 2.5 GHz frequency is susceptible to noise and congestion but it is much cheaper.
Also, if you are in a crowded residential area, a dual band router is the best option. One dual band router is equipped with two radios, one operating at 2.4 GHz and the other running at 5 GHz. A dual band designed to set up two separate wireless networks will help improve the speed in areas with crowded wireless networks.
3. Antenna limit of the router
For a smooth connection to the router, it is important that the router is centrally located in your home or office, away from physical obstructions and other jamming devices. Even so, even from an open location, depending on the type of router, you may still be disconnected in some indoor areas.
The range of a router cannot be measured directly, it depends on many different factors. The only way to solve this problem is to consider the dBi rating of the router antenna, which is largely included in the specifications.

If you need a WiFi router for a small apartment, 2-4dBi is sufficient, but for large offices or apartments with multiple floors, you need a router with a higher dBi rating.
4. MU-MIMO antenna
MIMO technology helps your router to transmit signals very quickly by sending data through multiple antennas. With MIMO, routers can target multiple devices (smartphones, tablets, computers) at specific locations at the same time. This is done through another technique called MU-MIMO. However, only routers that support 802.11ac are MU-MIMO compatible.
To confirm whether your router supports MU-MIMO, check the product package or specification sheet. Vendors often tell if the router supports MU-MIMO.
5. Security of the router
The wireless network is insecure because anyone within range can track online activities, hijack the Internet, access device files, and infect system viruses. your.
Today, new model routers can come with many additional security features, including the ability to add encryption, monitor other devices and block unwanted users from the network, but Normal routing is still vulnerable to attack.
When buying a WiFi router, make sure you get a set of support for at least the WPA2 security standard. Also, make sure every device you add to the network supports WPA2.
6. Router port
Most routers have a USB port, but for some devices, the USB port is only used to transfer setup information from the router to the client computer.
The latest WiFi router’s USB ports allow you to connect a large hard drive to it and every device connected to the network will have access to resources on that storage. Also, you should consider whether it is a USB 2.0 or 3.0 port. USB 3.0 is a better option because it allows you to connect any type of accessory.
The cost of a WiFi router is primarily determined by its antenna, port and other features. The best router with full features costs up to 225 USD. If you only have a tight budget, you can opt for the lower versions.
To secure the wifi modem at your home or work, you should make it a habit to regularly change the wifi password with long and difficult passwords, maintaining this routine will help keep the network connection stable, without delay. because so many devices are connected and, most importantly, your data is protected.
