I have been reading everywhere that I should be able to view wifi signal strength using iwconfig or wavemon but I am not getting that information when I use either of them. I can connect to wifi, and the signal strength icon with the bars in gnome3 works fine, but I want more specific information.
Here is what happens when I use iwconfig:
lo no wireless extensions. eth1 IEEE 802.11abg ESSID:"WIFI_ROUTER" Mode:Managed Frequency:2.437 GHz Access Point: 82:0C:E5:2V:7E:48 Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off eth0 no wireless extensions.
When using wavemon I get mostly the same info but in the Levels area, it says NO INTERFACE DATA. I assume this is where I should be able to view the signal strength.
What can I do to make the signal strength show up?
