Can the router signal be improved by replacing the high-gain antenna? Usually not, network information is not the same as broadcast. It is two-way. High-gain antennas are very cheap, but they are not available on mobile phones and other clients. The terminal uplink signal is very weak, and the routing signal is not very helpful. Of course, using a high-gain antenna on the one hand, and improving the receiving sensitivity on the other hand, will definitely improve significantly. But the price of improving the receiving sensitivity can be high, which is much more expensive than a high-gain antenna.

Going back to this question, you need to know what equipment is used. If it is a laptop, you can buy a long network cable if it is convenient to connect directly to the wired network, and the stability and performance are guaranteed.

If it is a pure wireless device, the solution can be to buy a wireless device that supports Repeater or Bridge mode to play the role of relay amplification.

Your own DIY signal amplifier is technically difficult, and you need professional test equipment. Only professionals can use it, not suitable for general users. Look for high-gain antenna manufacturers, choose Tiankele, standard parts will be shipped on the same day, customized parts will be shipped around one week, and the quality will be checked at any time.
