Hello,
i tested my Zaurus Sl 5500 with tkcrom and have no problems with the D-Link DCF 660.
Browse the Internet and Mails.
With Hentges 3.5.3 and Cardfilesystem on SD-Card I get the IP from the DHCP-Server.
ping 192.168.0.5 (Suse Server) says after 20min(!) only host name lookup failure.

I flashd the ROM five times and more with three downloads of Opie 3.5.3.
Two Kernels (64-0 and 48-16) and don't find the problem!
route add default gw 192.168.0.5 wlan0 brings zero resault
What can i do?
Greetings
Jürgen
