MY QUESTION is: 

Can I upgrade firmware PRI 1.1.1/STA 1.5.6 on this card?
Becouse, on the www.dlink.com I can't find firmware for DWL-520 

I find somewhere information for problem with STA:1.3.4
may be corrupt packets .. or something like this .. 

If this upgrade is possible,
where I can get this firmware , and
how is better to upgrade: with windoze utils or with prism_srec ? 

btw, I get tarball with STA1.5.6 from message:
http://lists.shmoo.com/pipermail/hostap/2003-January/001089.html
following link http://aldebaran.feld.cvut.cz/~xmyslik/wifi 

Just I can't understand, is all this firmwares are compatible wiht all
prism2;2.5 chipsets
or may be firmware 1.4.9 is good ? 

Thanks in advance! 

sorry for my bad english , I'm Bulgarian =) 

bye
