Replace antennas for wireless routers to enhance signal
The wireless network coverage is very small and the transmission distance is very short. What is the solution? Buying a wireless router as a bridge is too wasteful! Replace the antennas, and the low-end wireless routers are all tied to the antennas, and cannot be replaced! If you still have
A curious mind, then, you should pick up the tools to install a new antenna for your wireless router and give it a chance to regenerate.
Wireless networks urgently need to expand
The first floor is the large living room, the second floor is the bedroom and study, the wireless router is on the second floor staircase, and the bedroom and study have fixed wired network interfaces. Recently, it is necessary to use the wireless network in the living room on the first floor, only to find that because the wireless router is placed on the second floor, the living room on the first floor can only receive weak signals and cannot guarantee normal application. Add a feeder at the antenna end of the wireless router to extend the antenna to the first floor, so that the first floor can also access the wireless network on the basis of the original network. However, wireless routers use a fixed antenna design (most home-grade wireless routers under 150 yuan use this type of design), and signal extension cables cannot be used on the antenna interface. What to do? Remove it and solder a new antenna to it! The retrofitted wireless router has a pluggable antenna base, so you can replace directional antennas, sector antennas, high-gain omnidirectional antennas and other equipment according to the actual environment. Wireless The use of routers is more flexible.
What materials are needed for the wireless network signal on the first floor before and after the renovation?
Purchase the antenna of the wireless router needed for the transformation. You can't buy just one antenna like the original replacement of the wireless router. Instead, you should buy a set of wireless router antennas including the antenna base and the antenna. Because the entire antenna system is replaced, if you only purchase the antenna without the antenna base, you cannot connect to the router motherboard. The antenna needs to be purchased together with the base. The antenna of the wireless router is divided into direct connection and feeder base connection.
The direct connection type is suitable for users who just want to replace the higher gain antenna on the wireless router to expand the coverage of the wireless signal. Such high-gain antennas currently sell for 20 to 40 yuan. The feeder base type is suitable for users who need to change the wireless network coverage without moving the wireless router. If the wireless router is on the second floor, the original wireless signal mainly covers the second floor. After using the feeder base, you can move the coverage of the wireless signal from the second floor to the first floor without moving the wireless router, which is more suitable for the author. This type of antenna is priced at RMB 50 ~ 150.
How to play Tuojie?
1, remove the old antenna
First, open the shell of the wireless router, and locate the antenna solder joint on the wireless router's main board along the position of the original antenna. Since the antenna part of the wireless router is "output port + internal transmission feeder + fixed antenna", if you want to make the antenna replaceable and support feeder base products, you need to transform it into "output port + internal transmission feeder + pluggable base" + Pluggable antenna ", so the most critical step is to replace the internal transmission feeder. So follow the original antenna feeder and find the solder joint. Use a soldering iron to solder off the root of the original antenna feeder. Although this method is troublesome, it can ensure stable signal transmission. When soldering, pay attention to prevent static electricity from penetrating the chip on the wireless router's motherboard, so use a soldering iron with a ground wire. If the soldering iron does not have a ground wire, you need to unplug the soldering iron wire for passive welding after the soldering iron is heated.
2, welding new antenna
welding After removing the original antenna, solder the new antenna to the wireless router's motherboard. After the soldering is completed, check the solder joints to see if there is a short circuit. Since the base is directly connected to the transmission feeder, as long as the feeder drawn from the base is welded to the wireless router's motherboard, there is no need to prepare additional wires.
3. Fixed antenna base
After soldering the antenna connector, fix the antenna base. Because the original antenna base and the new antenna base may be fixed differently, you can use hot melt adhesive to fix the antenna base. Of course, if the placement of the wireless router is relatively hidden, the fixing step can also be omitted, but the feeder of the antenna base must be reinforced with adhesive tape to prevent solder joints from being soldered when pulled.
4, feeder feeder
Feeder is the wire used to connect the antenna base of the wireless router to the antenna. The feeder can be selected according to where the wireless network coverage needs to be moved, but the extension distance of the feeder should not exceed 10 meters, otherwise the wireless signal transmitted by the wireless router will be seriously attenuated. An antenna with a feeder can change the coverage of the wireless network. It is easy to find the welding point of the antenna along the feeder of the original antenna. After the transformation, the wireless network signal on the first floor has been greatly enhanced, which is almost the same as placing a wireless router alone. In addition, since the wireless network antenna is installed on the first floor ceiling, the second floor can also receive wireless signals.
