Well, if you can get 2.2 Mbps when the client is claiming speed is 1
Mbps, it should be easy to figure out which side is incorrect.. ;-)

Many Lucent/Orinoco client programs seem to use proprietary Lucent
frames for some link tests. Most Intersil Prism2 firmware versions do
not seem to reply to these frames in completely interoperable way and
the client side may thus report incorrect information.

In addition, that 2.2 Mbps is quite poor throughput, so I would assume
that the Orinoco card is having some issues with TX rate control. You
could try to verify from hostapd procfs file whether the frames are
received and sent using 11 Mbps during client->AP test.
