Replace the antenna for the wireless router to enhance the signal
The wireless network coverage is extremely small and the transmission distance is extremely short. What is the solution? Buying a wireless router for bridging is too wasteful! Replace the antenna, and low-end wireless routers are all bound to the antenna and cannot be replaced! If your brain is not degraded , If you still have curiosity, then you should pick up the tool to install a new antenna for the wireless router, giving it a new opportunity.
Wireless network urgently needs expansion
The first floor is the large living room, the second floor is the bedroom and the study room, the wireless router is at the stairway on the second floor, and the bedroom and study room have fixed wired network interfaces. Recently, I needed to use the wireless network in the living room on the first floor, and found 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 to the antenna end of the wireless router and extend the antenna to the first floor, so that the first floor can also be connected to the wireless network on the basis of the original network. However, the wireless router uses a fixed antenna design (most home-level wireless routers less than 150 yuan use this type of design), and it is impossible to use a signal extension feeder on the antenna interface. What to do? Remove it and weld a new antenna to it! The transformed wireless router has a pluggable antenna base. You can replace the directional antenna, sector antenna, high-gain omni-directional antenna and other equipment according to the actual environment. The use of routers is more flexible.
The wireless network signal on the first floor before and after the transformation. What materials does Extension World need?
To purchase the wireless router antenna required for the transformation, you cannot purchase only one antenna like the original wireless router antenna replacement. Instead, you should buy a wireless router antenna including the antenna base and the antenna. Because the entire antenna system is replaced, if you only purchase the antenna without purchasing the antenna base, it cannot be connected to the router motherboard. To transform the antenna, you need to purchase the wireless router antenna together with the base. The antenna is divided into direct connection and feeder base connection. The direct connection type is suitable for users who just want to replace a higher gain antenna on the wireless router to expand the wireless signal coverage. 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 wireless signal coverage from the second floor to the first floor without moving the wireless router.
How to install the antenna?
1. Remove the old antenna
First of all, open the casing of the wireless router, and follow the original antenna position to find the antenna welding port on the wireless router motherboard. Since the antenna part of the wireless router is "output port + internal transmission feeder + fixed antenna", if the antenna is to be replaceable and support feeder base products, it needs to be transformed 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 line and find the soldering point. Use an electric 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 motherboard, so use an electric soldering iron with a ground wire. If the electric soldering iron does not have a grounding wire, you need to unplug the electric soldering iron wire for passive soldering after the electric soldering iron is heated.
2. Weld the new antenna
After removing the original antenna, solder the new antenna to the motherboard of the wireless router. 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, it is only necessary to solder the feeder from the base to the main board of the wireless router, without additional wires.
3. Fix the antenna base
After soldering the antenna connector, fix the antenna base. Since the fixing methods of the original antenna base and the new antenna base may be different, hot melt glue can be used to fix the antenna base. Of course, if the wireless router is placed in a hidden position, the fixing step can also be omitted, but it is necessary to use tape to reinforce the feeder of the antenna base to prevent false welding of the solder joints when pulled.
4. Connect the feeder
The feeder is the wire used to connect the antenna base of the wireless router and 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 attenuated very seriously. The antenna with a feeder can change the wireless network coverage. It is easy to find the welding spot of the antenna by following the original antenna's feeder. After transformation, the wireless network signal on the first floor has been greatly enhanced, almost the same as placing a wireless router alone. In addition, because the wireless network antenna is installed on the ceiling of the first floor, wireless signals can also be received on the second floor.
