Hi there,<br><br>I have a new Z-Com ZI-325HP+ running with Ubuntu 6.10 (2.6.17-10generic) on a IBM X-series laptop. The card is running fine and connecting to my AP, which is about 10 m away with one medium wall inbetween, with 11Mbit all the time. I usw WPA-TKIP encryption and the NetworkManager tool with gnome-applet to connect.
<br>My problem is, that I get very low transfer speeds. I tried downloading via FTP from another machine in the local LAN and got about 200 Kbyte/sec. With placing the laptop 1 m in direct sight to the AP I get no more than 300 Kbyte/sec.
<br>I have an Atheros 802.11bg card working with madwifi-drivers and get around 2000 Kbyte/sec with this card (sure, it is g and not b).<br>Where could be the problem?<br><br>iwconfig:<br>--------------------<br>wifi0 IEEE
