上网经常要用到无线路由器,家中空间太大,无线信号的强度不够,可以自己动手制作个简单的信号放大器。将空易拉罐洗干净,拔掉拉环。将罐底用剪刀剪掉,接着用剪刀切割罐顶,不要全部剪掉,留下一部分,剩下的部分展开。展开铁皮后,将易拉灌倒立,天线插入易拉罐口,这样一个wifi信号放大器就做好了。制作的过程中一定要注意安全,免得划破手指。 Internet often use a wireless router, home space is too large, the wireless signal strength is not enough, you can create a simple signal amplifier yourself. Empty the cans to clean, pull the pull ring. Cut the bottom of the tank with scissors, then cut the top of the tank with scissors. Do not cut off all, leave a portion, and the rest unfolded. Unfolding the metal, will be easy to pull irrigation upside down, the antenna into the mouth of the cans, such a wifi signal amplifier is done. Production process must pay attention to safety, so that you can not cut your fingers.
