I've compiled r83 (and r84 from svn) on my Ubuntu 6.06 installation and
got it to work. It connects to my WLAN (even with WPA-PSK via
wpa_supplicant) but seems to be extremely slow.
Pings to my router (which is really close to it) are high and vary
heavily (rtt min/avg/max/mdev = 16.003/64.315/107.675/31.142 ms with
occasional packet loss) while it's in the range of 1ms on an other
machine. Transferring data (with Samba) goes with only a few kBps.
I'm not sure how to diagnose this, but "iwconfig wlan0" gives:
Link Quality=100/100 Signal level=73/100 Noise level=0/100
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:379
Tx excessive retries:11105 Invalid misc:0 Missed beacon:0
The "Rx invalid frag" and "Tx excessive retries" keep increassing. I've
tried playing with the rate, and other iwconfig values, without success
(probably due to my very limited wifi-knowledge). What do these
statistics mean and are they related to the slowness?
What should I do to debug the slowness? Are there other revisions I
should try (or even try zd1211rw)?
Thanks in advance for any reply,
