Peter,
The KN-50 uses the firmware on the radio card. The newest cards from Orinoco
are not in compatible in the KN-50 because of firmware, specifically they
are different radios and do not use the same drivers. The issue that is
being seen from the reports received to date is not as simple as replacing a
firmware version, if so, we would gladly have recommended a version. The
KN-50 code base is unique to the software loads for Ubicom processors. It is
not the same code base as other products, the firmware versions mentioned
are not key to the problem, although they may impact it some. The hypothesis
mentioned below about polling is incorrect. Please contact KarlNet support
off-list for further assistance.

Hi,
may be there is big misunderstanding.
Timothy reported, that:

Karlnet Support replied:

So, there is essential question:
IS current KN50 device software able to load proper secondary firmware to
RAM
of Orinoco card?!
If Yes, we must know exact version of this secondary firmware.
If not, then is very important what firmware is flashed to CARD with WSU
utility. I think, that NEW Orinoco cards are allways loaded with firmware
incompatible with TURBOCELL.
So , all we need is to flash every Orinoco card used in KN50 with proper
compatible firmware: 6.08, 7.52, 8.10, 8.74 (thanks for correction) via WSU
utility. It is very simple.
I will guess what is the problem if Orinoco card with incompatible firmware
is
used:
Card do es not have support for polling. There is support for CSMA/CA only,
so
card must wait for free medium, before is able to transmit. And this is
reason
of horrible throughput in environment, where is big interference. May be is
then transmitting with delay and we have "hidden node problem", even if
there
is no interference. Againg, it is only guess.
