In general, when you buy a router, you mainly look at the following parameters: 1. Transmission Standard [Important] 2, antenna gain [important] 3, power supply method [general] 4, processor [important] 5. Memory, Flash, etc. [General] Of course, there are other data parameters such as brands, but for people who do not understand or are just ordinary households, knowing the above data is good or bad. Transmission standard The most direct effect on network speed and connection is IEEE 802.11b/g/n/ac. This standard is an international standard and represents the level of data transmission rate of the network. It increases from left to right. The most common of us is to support the IEEE 802.11N protocol (up to a maximum speed of 300M). If you see a router writing IEEE 802.11G, the merchant says that it can reach 300M, which is why you can only support up to the 54M standard. router The IEEE 802.11N can support both 2.4 GHz and 5 GHz frequency bands, which is what people often call dual-frequency routing. Antenna gain The quality of this data determines the signal strength of the router. We must first say a misunderstanding. The more signals the antenna has, the better. This conclusion is not accurate. If you are buying a 300M router, whether they are 2 antennas or 4 antennas, the whole is 300M and it doesn't get bigger. The signal strength depends on the antenna gain, placement position, and some related chips. The gain of the antenna may not be well understood by everyone. Let's focus on that. This parameter is not visible in many router specifications. Nowadays, the general router antenna gain is 2dBi/3dBi/5dBi. dBi It is a relevant unit of power gain. Theoretically, the bigger the number is, the better. It is very likely that general manufacturers do not label 2 and 3, and if they reach 5dBi, they will basically come out and blow it out. Everyone can simply understand that 5dBi guarantees perfect performance within 5 meters. (Also judge according to the actual situation, such as housing structure, etc.). 1. Search for advanced 802.11g wireless broadband routers before purchasing. Find articles on wireless router ratings and assessments on the Internet or in computer magazines. For example, on the PCMag.com website. When visiting the homepage of this site, enter "Wireless Router" in the search box, click on the "Assessment" button, and click on "Search" to see expert evaluation articles. 2, find low prices and discounts. Buy a router that gives you the best value. "Comparatively cheap" does not mean that the product is not good. Manufacturers and suppliers sometimes discount or other discounts that are lower than the listed prices. 3, pay attention to the situation of quality assurance. This is important for making decisions. Each product has a quality assurance period. A long quality assurance period means that this product can get better technical support and manufacturers have more confidence in this product. 4. Check what function this router supports. Not all wireless routers support the same range of features. Learn what features you need now and what features you need in the future. Some of the features that need to be considered include high-speed Internet connectivity, basic file and print sharing, transmission of audio and image files, multiplayer gaming on the Internet, support for streaming video, and extensive use of the LAN by multiple users. 5. Consider the ease of use and setup before buying a broadband wireless router. 6. Check compatibility with your current network adapter (Ethernet card). If your Wi-Fi device is manufactured by a single vendor, consider buying a wireless router from the same vendor. Manufacturer's unity means higher performance because the device has been tested and more fully optimized and uses the same communication protocol. 7. Consider your need for speed. Wireless routers cannot speed up your internet connection. However, wireless routers are very important for multi-player games on the local area network and for solving traffic congestion in busy LANs.
