I don't know if somebody improved the dibcom driver, but for my experience the signal strength numbers are not useful, they only go from a small number or jump to maximum, so don't trust them. I think there where also some issues with signal strength on some hardware... but I'm not sure about that.<br>
Apart from that signal issues your device seems to work perfectly, could you submit the patch to the list to add it to current version?<br><br>Albert<br><br><div class="gmail_quote">2009/1/6 Yusuf Altin <span dir="ltr"><<a href="mailto:yusuf.altin@t-online.de">yusuf.altin@t-online.de</a>></span><br>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">ok, now I'm a step ahead, i moved my device to the section around line<br>
1562. By using w_scan every occupied frequencys were found, but scanning<br>
for services (pids) isn't successful at all. The card finds only a few<br>
channels and the signal strength is very poor -> a lot of artefacts. My<br>
Antenna is good justified and with Windows and the Original Software it<br>
works well.<br>
Is there any way to optimize the reception?<br>
<br>
PS: My Card gots a led, it turns always on when i connect it with my<br>
notebook.<br>
