Since in both devices (my i8k and the airport) orinoco cards are used, I
thought, I'm on the right place. ;)

iwconfig shows me the rates from 1MB up to 11MBs. Depending on the
distance to the airport. - This seems to work correctly.
Anyway, that is brutto, netto it should be about 1MB/s when I'm near to
the router.
(Right now, I am in basement with five walls between me and the router;
and this is the output of iwconfig:
         Mode:Managed  Frequency:2.452GHz  Access Point:
         Bit Rate:2Mb/s   Tx-Power=15 dBm   Sensitivity:3/3
         Link Quality:13/92  Signal level:-83 dBm  Noise level:-96 dBm

on the ground-floor - three walls between:
         Mode:Managed  Frequency:2.452GHz  Access Point:
         Bit Rate:5.5Mb/s   Tx-Power=15 dBm   Sensitivity:3/3
         Retry limit:4   RTS thr:off   Fragment thr:2347 B
         Link Quality:17/92  Signal level:-79 dBm  Noise level:-96 dBm

As you can see, the Bit Rate works correctly.
Even when I'm close to the router, the Link Quality is never better
then 50/92.)
The best I ever seen even when the hack version is about 75 so don't
feel bad... it should get way more then 200K are you sure the get a
fast enought server on the other end able to send faster then 200k?
If the card show you 11Mb/s whilch mean ( as I understand ) the card
is receving 100k+ package per second... but it can still max out but
other reason.

Yesterday I tried to compile the new pcmcia-cs from sourceforge.
Unfortunately the new package isn't working. It compiles without errors,
but when I stick the card into the dell, I get errors and the module
orinoco_cs won't load.
(card services don't match).
I also upgraded the nessesary debian-packages. - Without any change in
behavior.

Did you compile with the right kernel-source that you are using?
Good Luck
Alex
