How to choose a home wireless router

802.11N Wireless network technology standards officially approved, which undoubtedly accelerated the popularity of wireless networks, lighting the vast majority of Internet users to the enthusiasm of the transition to wireless networks. To this end, this article will introduce you to the wireless router to buy knowledge.





simply, the wireless router is integrated with the routing function and wireless access function of the network equipment, the device can be connected to the wired LAN and WAN, generally support the popular adsl/cable modem/optical fiber and other broadband access mode. The wireless router can realize the sharing of Internet connection in the home wireless network, and realize the sharing access of all kinds of broadband. At present, there are many kinds of products available on the market, so it is unavoidable to encounter various problems when buying.





1. Port





refers to the LAN port and WAN port of the wireless device. Without a WAN, you will not be able to connect to the Internet, and without a LAN port, you will not be able to connect to devices such as network adapters, switches, etc.





purchase proposal: At present, most wireless router products provide 4 switch (LAN) port and a WAN port, the port rate is generally adaptive 10/100mbps, and have auto Mdi/mdix (automatic crossover), so that users do not need to understand the type of network cable, can be identified automatically. LAN ports allow you to connect to network adapters, switches, and other network devices in a wired LAN, and WAN ports can be connected to broadband network devices, such as ADSL modems, Cable modems, etc.





Ordinary Home users in the purchase of home wireless routers, it is important to pay attention to whether the switch port, the port can guarantee the computer's wired Internet, in the wired LAN based on the formation of Wired, wireless hybrid network. In addition, some wireless router products may provide 5 switch ports.





2. Transmission Rate





Wireless router transmission rate directly affects the ability to send and receive data, transmission rate is not the faster the better, but also to consider whether compatible.





Buy suggestions: At present, based on the IEEE 802.11G standard 54Mbps wireless network products have slowly replaced the IEEE 802.11b standard products, occupy the mainstream market position. However, for ordinary home users, 11Mbps wireless router products are basically enough, and technology than 54Mbps and 108Mbps of products mature and stable. Although in actual transmission, this kind of product theory transmission rate is much lower than 11Mbps, only about half of 11Mbps, but in the current limited ADSL network broadband enough.





of course, if you have the conditions, you can choose 54Mbps products, this can meet the wireless LAN internal data high-speed transmission needs. However, pay attention to the use of the wireless network card in the home transmission rate, because the 54/108mbps wireless router when the transmission rate is generally adaptive state, can be based on the speed of the surrounding wireless environment automatically adjust the rate, if it is 11Mbps wireless network card, then automatically adjust to 11Mbps for transmission.





3. Transmission Distance





transmission distance refers to the wireless network equipment transmitting signal can reach the farthest distance, the greater the transmission distance, the wider the range of signal coverage.





purchase Suggestion: Theoretically, the wireless router transmission distance can reach at least 100 meters, outdoors the farthest 300 meters. However, in the actual case, the maximum distance of transmission depends on the surrounding environment, such as the walls of the room more, there are metal barriers, microwave ovens, cordless phones, which will affect the transmission of wireless routers.





Housing Area of 120 square meters, if the obstacles are not much, wireless signal can basically cover the entire interior. In the purchase of wireless router products, it is recommended to choose the theoretical transmission distance of larger products.





4. Access Control





through the wireless Router access control function can restrict access to the site and access to the time, the wireless Product access control function is best simple and practical.





Buy advice: In order to prevent children in the middle of the night to surf the internet and browse bad content of the site, generally through the wireless router access control function to set. For example, through the Domain name filter (URL filtering) function can control the Internet date, time, set to prohibit access to the site keyword. In the purchase of wireless router products, it is recommended to try these features hands-on, because in some low-end products only provide a simple domain name filtering function.





5. Price





Price is to buy any product need to consider the problem, for ordinary home users, wireless router price is not necessarily higher the better, according to their own actual situation to choose.





purchase proposal: Compared with the same period last year, the price of wireless routers has dropped a lot, the current ordinary home wireless router prices are acceptable. When choosing a wireless router, it is recommended that you choose the wireless kit provided by the manufacturer, which will make you more affordable.





6. Brand





many times, the brand is about the consumer's choice. In the purchase of wireless router products, it is good to look for well-known brands.





Purchase suggestions: In the network technology, foreign brands do occupy a certain advantage, but not absolute, because some domestic companies and foreign companies have strategic cooperation, such as Huawei, 3Com. In the purchase of wireless router products, we must buy well-known brands of products, such as Linksys, Netgear, Tp-link, in the number of Yi, and so on, do not covet a cheap, select unknown products.
