问题描述
我想知道是否存在任何命令行选项或GUI工具(Ubuntu 11.10),以便我可以测量给定位置的无线信号强度。我有一个房子,在所有角落都不容易接触无线网络我想知道在哪个角落或房间信号很弱。
最佳解决办法
在命令行上,您可以使用iwconfig
并查找”Link Quality”和”Signal level”值。
当使用上网本走动时,我经常使用这个命令每秒更新iwconfig的输出:
watch -n1 iwconfig
次佳解决办法
wavemon – 具有彩色显示和许多易于阅读的信息的控制台应用程序。
要安装它,请输入以下命令:
sudo apt-get update
sudo apt-get install wavemon
要运行它,请输入:
wavemon
第三种解决办法
更漂亮的一个:
watch -n1 "awk 'NR==3 {print \"WiFi Signal Strength = \" \$3 \"00 %\"}''' /proc/net/wireless"

第四种办法
wavemon有一个非常好的界面:
wavemon is a ncurses-based monitor for wireless devices. It allows you to watch the signal and noise levels, packet statistics, device configuration, and network parameters of your wireless network hardware. It has currently only been tested with the Lucent Orinoco series of cards, although it should work (with varying features) with all devices supported by the wireless kernel extensions written by Jean Tourrilhes.
要安装它,请输入以下命令:
sudo apt-get update
sudo apt-get install wavemon
要运行它,请键入
wavemon
