Replace the antenna for the wireless WIFI 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, low-end wireless routers are all bound to the antenna and cannot be replaced! If your brain has not degenerated , If you are still curious, then you should pick up the tool to install a new antenna for the wireless router and give it a new chance.

Wireless network urgently needs to expand

The first floor is the large living room, the second floor is the bedroom and study, the wireless router is at the stairs on the second floor, and the bedroom and study have fixed wired network interfaces. Recently, I needed 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 the normal application cannot be guaranteed. 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 access the wireless network on the basis of the original network. However, the wireless router uses a fixed antenna design (most home-grade wireless routers within 150 yuan use this design), and it is impossible to use the signal extension feeder on the antenna interface. What should I do? Remove it and weld a new antenna to it! The renovated wireless router, due to the addition of a pluggable antenna base, can replace directional antennas, sector antennas, high-gain omnidirectional antennas and other equipment according to the actual environment. The use of routers is more flexible.

What materials are needed to expand the wireless network signal on the first floor before and after the renovation?

To buy the wireless router antenna required for the transformation, you can't just buy one antenna like replacing the antenna for the wireless router, but you should buy a set of wireless router antenna including the antenna base and the antenna. Since the entire antenna system is replaced, if you only purchase the antenna without the antenna base, it cannot be connected to the router motherboard. The modified antenna needs to be purchased together with the base. The wireless router antenna 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 are currently priced at 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, the coverage of the wireless signal can be moved from the second floor to the first floor without moving the wireless router, which is more suitable for the author. The price of such antennas is 50 yuan to 150 yuan.

How to play Tuojie?

1. Remove the old antenna

First, disassemble the casing of the wireless router, and find the antenna welding port on the motherboard of the wireless router 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 type 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 to 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, be careful to prevent static electricity from penetrating the chip on the motherboard of the wireless router, so use an electric soldering iron with a grounding wire. If the soldering iron does not have a ground wire, it is necessary to unplug the wire of the soldering iron for passive soldering after the soldering iron is heated.

2. Solder the new antenna

After removing the original antenna, solder the new antenna to the motherboard of the wireless router. After the soldering is completed, you need to 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 drawn from the base to the mainboard of the wireless router, and there is no need to prepare additional wires.

3. Fixed antenna base

After soldering the antenna connector, then fix the antenna base. Since the original antenna base and the new antenna base may be fixed differently, you can use hot melt glue to fix the antenna base. Of course, if the location of the wireless router is relatively secret, the fixing step can also be omitted, but the feeder of the antenna base must be reinforced with adhesive tape to prevent the solder joints from being soldered when pulled.

4. Connect the feeder

The feeder is the wire used to connect the wireless router antenna base 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. 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 no different from placing a wireless router alone. In addition, since the wireless network antenna is installed on the ceiling of the first floor, the second floor can also receive wireless signals.
