[zd1211-devs] Copy seems to be working, speed is the next issue

[Jon S. <jon...@gm...>]

I just did a 15GB copy test and averaged 13Mb/sec, Windows can copy
the same files at 19Mb/sec. It appears that CIFS has higher throughput
than SMBFS (10Mb).

I have the AP set to channel 1 and in 11g only mode. The vendor driver
has a way of setting 11g only mode on the client, does zd1211rw have
the same or is it automatic? Server is set to short preamble, what is
zd1211rw doing? Link is connected at 54Mb.

I have 1000's of these in my log. 10-15 per second
handle_retry_failed_int() retry failed interrupt
If these are low level packet transmission failures that are being
recovered by the TCP layer that could easily explain 13Mb vs 19Mb.

I also have a few of these, once every minute
