[hardy] Network Manager is sluggish in making wireless connection and sometimes fails. When failure, it sends CPU usage skyhigh.

[Pjotr12345]

In Ubuntu 8.04 Hardy Heron, Network Manager is very slow in recognizing available wireless networks and also very slow in making a wireless connection. When it fails to make a connection (often), it keeps trying and sends CPU usage skyhigh (Intel Core 2 Duo). Only a reboot will remedy this: switching back to a wired connection is impossible then.

This is strange, because Ubuntu 7.10 Gutsy Gibbon works flawlessly with this wireless USB dongle (Sitecom WL-172).

The output of lshw is attached.

Same here
Network Manager cannot connect to wireless networks. It consumes 99% of cpu

Confirmed on network-manager 0.6.6-0ubuntu2. A new bug was generated about the same issue. Bug #204897

Maybe a duplicate of bug 204768.
