Ovislink Airlink WUSB11 disconnecting

Hello all

I've pb with my wireless USB adapter.
After few hours of reading docs and pages on web, deployment on kernel sources and solving some links problems, I managed to do sucessfull driver compilation and deployment (no more errors). 
I've successfully connected to another wifi client in ad-hoc mode, getting 90% signal strength and zero packet loss.

After some short time of happyness, I've found out that after I tranfer some data (50-100 MB max) wireless connection slows down drastically, sometimes it gets interrupted completely. It stays so until I reconnect.

I'm using Fedora core 5, latest kernel 2.6.17-1.2157_FC and 0.13 version of Berlios driver.

I didn't understand that firmware part on docs completely - there isn't hotplug in Fedora core 5, there is udev instead. But I haven't found any information how to make udev act instead od hotplug. I've tried to load firmware using utility atmel_fw.pl, but I got error,

wlan0 is not an Atmel interface at /usr/sbin/atmel_fwl line 35.

I'm quite sure that it is atmel (it's written on chip and drivers work), I've tried to resolve this pb, but I do not know perl enough.
Other thing is - that I do not know if use of this firmware could fix my pb with interupted connection.

Next step should be pasting of some logs, but I haven't found much of interrest, only this:

I should be able to send any info you may need, including debug. Just ask please 
I've seen some posts similar to my pb, but without any answer. Maybe I overlooked something or maybe I'm doing something wrong. Do you have any idea?

Thank you
