           Summary: madwifi on WG311T only operates when set to 802.11b mode
           Product: openSUSE 11.1
           Version: Final
          Platform: Other
        OS/Version: openSUSE 11.1
            Status: NEW

          Priority: P5 - None
         Component: Network

I've installed madwifi 11.1 64-bit packages from
ftp5.gwdg.de/pub/opensuse/repositories/home:/drankinatty/openSUSE_11.1/x86_64/
as the ath5k driver didn't work for me
(https://bugzilla.novell.com/show_bug.cgi?id=463247) on opensuse 11.1 64 bit
for my WG311T card.

I installed the RPM packages as normal and iwlist ath0 scan showed my
WEP-encrypted network. I configured the card in YAST to enter my ESSID and 128
bit hex key. On restart of network I had high packet loss and high ping times
when pinging my router. Typical was up to 80% packet loss and some ping times
over 10,000 ms and lots of timeouts.

I found that the solution to this was to restrict the card to 802.11b speed by
doing 'iwpriv ath0 mode 2'. However, on 10.3 with the madwifi packages from
madwifi.org/suse/10.3 I never had to do this. This improved the result to:

50 packets transmitted, 48 received, 4% packet loss, time 49257ms
rtt min/avg/max/mdev = 3.536/63.800/609.739/130.083 ms

For comparison my Samsung Q45 laptop on the same desk as the PC has the same
YAST config for its Intel wireless card, connects at 40Mb/s or more and can
ping the router with 0% packet loss like this:

50 packets transmitted, 50 received, 0% packet loss, time 49212ms
rtt min/avg/max/mdev = 1.789/3.957/76.822/10.867 ms

Also, on Windows XP the WG311T has continued to work as before i.e. no packet
loss.

I submit this bug as some regression in the madwifi packages that has forced me
to restrict the connection to 802.11b when I didn't have to on 10.3.
