Wireless : refreshing network list [Feisty]
Hello,
I've been searching on google, the ubuntu wiki-pages and several forums, but I can't seem to locate the answer to this one. When I log in to Ubuntu the NetworkManager Applet (0.6.4) [Gnome applet] is showing all the wireless network connections, and I can connect fast and easy (with one click) to the desired network. Only, when changing the environment (say : modem is turned off, and a new modem is turned on) it keeps showing me the old list, and not the new one. Also : when I turn off the wireless card on my laptop, and then turn it back on, it also does not refresh the network list and I cannot connect to a new network. So I have to reboot to get a new network list. The rebooting reminds to much of ms windows, so I am looking for a cleaner way of refreshing my network list when I want to. Does anyone here know how to do this ? |
That's a bug in networkmanager. You may use an alternative like wlassistant.

my preferred way to refresh available wireless networks is using the watch command
Code:
watch -n 1 "iwlist eth1 scanning" and eth1 is your wireless device PS: sometimes the network manager applet work's just fine when it's doesn't I just use Code:
killall nm-applet |
Thank you both for the reply.
The command line option is the one I was looking for, since wlassistant is a KDE frontend. But how do I scroll down in the list ? I receive the following list, now I just need to be able to also what comes next on the screen, and I can't seem to scroll down to it. This is an example. It ends halfway the information for the third available network. How do I reach the rest of the information ? Code:
Cell 03 - Address: 00:11:50:57:B3:53 The full information being of course these lines (and a possible fourth network) Code:
Pairwise Ciphers (1) : TKIP |
watching
watch -n1 -d 'iwlist eth1 scanning | grep ESSID'
Will give you a list of the networks in a short list The -d highlights the differences in watch. |
you can maximize the terminal window and chose a smaller font in profiles so all "cell's" are visible.
see "man grep" or "grep --help" and try tweaking the grep command for yourself. Here's an example: Quote:

Perfect, the addition of grep was exactly what I needed.
Another day, another lesson. Thank you very much. |
