I think using such a high level protocol for speed tests is a mistake and has certainly wasted some of your time so far. You should try low-level TCP transfers using netcat or something. I have personally had trouble making cifs/samba perform at something comparable to the available network bandwidth. You should also now retest the vendor driver and see if you can reproduce the vendor-driver-is-2x-faster thing. You also need to explicitly test downstream and upstream separately, and classify the problems by direction. > I have 1000's of these in my log. 10-15 per second > handle_retry_failed_int() retry failed interrupt These are generated for frame transmission failures (read: no ACK). You get several of them for each frame as they are retried multiple times before it gives up. > I also have a few of these, once every minute > [21901.205436] zd1211rw 5-1.4:1.0: zd_usb_ioread16v() read timed out > [21901.205442] zd1211rw 5-1.4:1.0: zd_chip_control_leds error -110 You could try disabling the LED code and seeing if that has an effect on performance. > Hit an assert: > Jan 4 16:53:21 jonsmirl kernel: [19010.649771] > drivers/net/wireless/zd1211rw/zd_chip.c:1461 ASSERT r >= 0 VIOLATED! > Jan 4 16:53:21 jonsmirl kernel: [19010.649790] > [pg0+946006505/1069057024] zd_rx_qual_percent+0x49/0x170 [zd1211rw] http://bugzilla.kernel.org/show_bug.cgi?id=7752 > Jan 4 16:53:21 jonsmirl kernel: [19010.649987] zd1211rw 5-1.4:1.0: > zd_mac_rx() Error in packet.
