Comment 4 for bug 1014893

My problem is quite similar to the one of Dima, the colleague who has filed this bug. That's why, I have "confirmed" it.
In several preceding Kubuntu editions, KNetworkManager functioned quite well - both wired and wireless. Unlike Dima, I often need wireless connections at the machine I am working on right now: a HP Pavlion dm 1 netbook, 32 bits, Kubuntu 12.04 along with KDE 4.8.4. With this configuration, I do have difficulties getting reliable WIFI connections. Often, the system keeps "configuring the interface" or "setting the network-address". Sometimes, the system keeps asking for a password already given in several times. Like in the case of Dima, this even happens when I am working with a wired connection.

By means of a few "workarounds" I do get connected via WIFI - however, it sometimes costs a lot of time and effort.

A few indications elsewhere at the internet possibly aim at a Linux Kernel problem. Someone who replied my question on this issue at the Kubuntu user forum, replied:

So far, I did not find exactly the article he may be pointing at. However, a few recent comments on WICD point in the same direction: see https://launchpad.net/wicd, under the heading "Recent posts".
Those comments aim at similar password and connection problems when using WICD - a package with the same functionality as KNetworkmanager.
Now, I am working with WIFI - with no interruptions so far. Before the reboot preceding this session, I did download and install a bunch of updates. However, I am not sure whether I already installed version *-26 of the kernel or anything else with a relevant bug fix. I will report my findings here after a few days.
