Kubuntu Hidden Wireless Network

Problem
There seems to be general issue with KDE's Network Manager and hidden wireless networks. [You can see (and vote for!) the bug here: https://bugs.kde.org/show_bug.cgi?id=209464.] You are trying to connect to a hidden network, and you create a profile for the specific wireless network in the KDE Network Manager. But for some reason you still can't connect.

I have encountered this problem for a while (Kubuntu 9.10, 10.04, 10.10, 11.04, 11.10, 12.04, and 12.10], but I finally found a solution today. A quick look tells me this bug has been around existed at least for 2 years. Pity they haven't fixed it.

Solution
Quick solution is to run this from command line:
sudo iwconfig wlan0 essid name_of_the_hidden_essid
This works even better if you have used KDE Network Manager to create a wireless profile with this hidden network's name already. You can setup password and such. This command only invokes connection to it, which is the real bug in the manager. It will read the profile you have previously stored.

Other solutions are to use a different network Manager, such as the network manager from Gnome/Ubuntu.

An even easier solution would be to just start broadcasting the SSID.
