Dynodon. I've got the same card, and the problems you described are familiar to me when I had the F5D7000. I had two of them and I could not get connected as normal user either.
The problem you mention however is solved with the drivers I received with the f5d7001. Although the stupid drivers are USA drivers ( can not use channel 12 and 13), both cards work with retricted user now. But it still is a strange card. The way I insert them in both pc's makes the antenna pointing downwards !
So update the drivers and it should be solved. But....after you uninstall the old drivers, first go to config, system, hardware, hardware management (? I think), click on the plus sign next to the network adapters and look if some installations are left behind. To make sure you see everything, click on 'display' (third main menu-option anyway, I'm not surehow it's called in the English version), and click on 'show hidden hardware' or something like that. Everything associated to the Belkin you can see must be uninstalled manually (you'll be surprized how much stays behind......) by right clicking on it and confirm the removal.
Than install the beta drivers like you nomrally would from.. ftp://supportbelkin.no-ip.org/networking/
. They are the latest, though beta but they work as well. If you do not trust them, download the latest approved drivers from their normal support site.
