你用那种天线, 使用的空间范围大概多少M,
说一下让我参考参考 天线还是很重要，如果信号较差，可以用易拉罐切成半球形来聚集一下信号
比如这里http://www.thinkpad.cn/forum/viewthread.php?tid=201823 我用的就是图片上的那种天线，使用效果还可以，在60平方的家里使用没什么死角，但要用usb的网卡。
tp-link 550g可以用
才发现的,呵呵,信号还不错, 我用这卡实现了无线PPPOE接入 楼上的,你的tp-link 550g 是用哪种芯片啊,你的ROS是什么版?回复 #20 zyling 的帖子
tp-link550g 在routeos 2.97版中显示为Atheros Ar5212 ,system resource> pci

说明可达到室内200M,不知有没有吹
