Unhappy DCOP errors when configuring ndiswrapper drivers for USB WLAN card (Kubuntu 10.04)

Hi all.

After much mucking around trying to get drivers to load, I have finally loaded the driver for a TP-Link TL-WN422G USB wireless using the Windows Wireless Drivers utility. However, when I try to use the utility to configure the network, I get a DCOP communications error "There was an error setting up inter-process communications for KDE. The message returned by the system was Could not read network connection list. /root/.DCOPserver_Max-Headroom__0 Please check that the "dcopserver" program is running! (It is). After this, other errors show up indicating that non-existent configuration files in root home folder are unwritable.
I've tried creating these files (touch) and setting them world-writable, but that made absolutely no difference.
I don't understand this:
  • I thought Ubuntu didn't use the root profile, but the user's profile; in any event, the Windows Wireless Drivers utility runs under kdesu, so should have universal write permissions
  • I'm not even sure this error has anything to do with a real network problem - merely a problem between desktop processes
Can anyone help? Please?

All the symptoms I describes are accurate, but ...

The interface works. So the lessons are

1. Don't rely on the Windows Wireless Drivers utility to configure the network.
2. When baulked in doing a job, don't trust the responses on just one approach. Always try to do several different ways before making an idiot of yourself in a public forum.
