I described my problems here (Dutch): http://www.ruwebit.net/article/320 Translation (English): http://translate.google.com/translate?u=http://www.ruwebit.net/article/320%26clean%26language=nl&ie=UTF-8&sl=nl&tl=en Translation (German): http://translate.google.com/translate?u=http://www.ruwebit.net/article/320%26clean%26language=nl&ie=UTF-8&sl=nl&tl=de See the table with the red entries. Some conclusions: The problem occurs with 802.11g (2.4 GHz). The problem doesn't occur with 802.11a (thus 5.0 GHz). The problem only affects upload speed, not download speed (up is under 1 MB/s, down is like 3.1 MB/s) The problem doesn't occur under Windows Vista. The problem doesn't occur using a Broadcom mini-PCI I used scp for testing I tested with an Acer Extensa 5220 laptop (Google for specs) with OpenSUSE 11.1 64-bit, the Windows Vista laptop I used for testing is an Acer Extensa 5260 with the same 3945ABG mini-PCI. lspci | grep ABG 04:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02) lsmod | grep iwl iwl3945 97652 0 rfkill 11044 2 iwl3945 mac80211 242320 1 iwl3945 led_class 5008 2 iwl3945,acer_wmi cfg80211 28200 2 iwl3945,mac80211 -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Because you didn't reply long enough (it's resolved as no-response). After you provide the info if it helps or not, reopen it of course. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
