Networking problems? Use tcpdump.

Every day can bring new knowledge :-) Lately, due to very bad quality of my GPRS link, I started keeping an open window with tcpdump in it, checking if the link works at all without introducing additional traffic.

It also showed me that I need a dns cache :-P as a big amount of requests were DNS requests about the same hosts. Like lots of queries for “AAAA? google.com” :-)

Also, after downloading winxp64 drivers for my AirForceOne (bcm43xx) WiFi card, I finally have a working WiFi. The reason for my troubles before was found to be incorrect firmware and I lost my patience for looking into correct firmware file…Nevertheless, ndiswrapper works like magic :-)
