为什么搜索不到5gwifi信号
搜索不到5G wifi信号的原因：在中国，只有149,153,157,161,165这5个信道可以供5G的wifi网络使用
wifi信号增强的方法：
1、漏勺增强法
这个和易拉罐增强的原理类似，将一个漏勺套在Wi-Fi天线上，就可以集中信号、加快信号传输速度。简单的漏勺放在WIFI信号上面就可以了，简单实用
2、把天线的角度调成一支垂直一支水平
当我们手机内部的天线和路由器的天线平行时，接收效果往往最佳，但现实生活中我们的手机和平板经常会因为不同的用途有时是横屏，有时是竖屏，内部的天线方向也因此不同，所以把路由器的天线调成不同方向，一根垂直，一根平行于地面，可以对应到不同的接受天线方向，让我们的手机无论怎么拿，都能保证最快的信号速度
3、路由器不要放在地上
很多人都喜欢把路由器放在地上，其实也是不对的，地板的材质很容易吸收掉Wi-Fi信号，而且部分信号都向下传送的，这部分信号相当于直接分给你楼下邻居了！自然信号就大打折扣了。所以正确的做法是，将路由器尽可能放在高处，信号才能充分利用，比如桌上、柜顶等
4、锡纸增强大法
用锡纸包住一个盆子或者大碗，随后将路由器放进该盆中或碗中，可以聚拢Wi-Fi信号，增强强度
5、易拉罐增强法
这是最长见，且简单的方法，将一个易拉罐切开，套在Wi-Fii的天线上，可以立马增强信号。这个方法是去年开始流行起来的，当时有很多人不信，后来央视亲自做了这个测试，发现确实可以让信号翻倍。这个的原理是路由器天线原本发射的是360度波，套上易拉罐后，能将电磁波向180度集中，从而加强了天线的发射和接受信号能力，让Wi-Fi信号翻倍
XBOX能否接投影仪玩？
X360有VGA视屏输出，可以连接投影仪。
但不推荐用投影仪玩X360。因为投影仪对市内光线要求高，每次投影的时候都要暗室内才看清，而且游戏效果也比不上液晶电视。高清液晶电视可以支持1080p全高清，而且受室内光线的影响少。
可以考虑SONY的BX40，40寸液晶，4000左右。SONY液晶电视的游戏效果都不错，可能由于是SONY本身也做游戏机。
扩展资料：
Xbox的研发代号是“中途岛”（Midway），二战期间美国太平洋舰队在中途岛一战重创日本海军，代号不知是否是一种巧合，暗示了微软与强大的日本游戏主机产业对抗的决心。
2000年3月10日，比尔·盖茨在GDC2000上正式公布Xbox，当时的Xbox尚未完成造型设计，比尔·盖茨掀开的盖头下是一台打造成X型的概念机。
本世纪伊始，时任NOA(任天堂美国分社)社长荒川实获悉微软即将全面进军TV游戏产业，深知微软底细的他立即飞回京都面见岳父山内溥（注1：NOA在西雅图的办公楼和微软总部仅一墙之隔）。
荒川的意愿是希望山内家族能够顺势将股份转让给微软全身而退，他的想法无疑触动了山内溥的逆鳞，翁婿二人自此彻底破脸。山内溥不惜投入超过十三亿美元巨额预算，联合松下公司开发NGC主机，并积极联络第三方厂商意图再次君临天下。
其以往诸如世嘉、NEC和索尼等竞争对手的身量实际都相差有限（注2：在索尼进入传统游戏产业的22年间，任天堂有16年的纯利润都要高于索尼集团），山内没有意识到和微软的巨大实力差距。

VB里一套API支持3D显示。输入各个点的位置就可以显示了。非常好用，你可以去
你可以去找一些相关的例子。
