Re: Newbie questions

Hi David

 The HW address loads up properly. Here are the ident outputs

ident: nic h/w: id=0x801b 1.0.0
ident: pri f/w: id=0x15   1.1.0
ident: sta f/w: id=0x1f   1.4.2

 Maybe that is the problem ? Should it be a higher version ?

 If you look at 
 
 http://linux.junsun.net/intersil-prism/stories/20031105_HenrikBrixAndersen-success.txt

 the poster there uses a similar card (WPC11) vs mine WCF12. He had the 
same versions 1.1.0/1.4.2 before. He later updated to 1.1.1/1.7.4 using 
WinUpdate to update the firmware. He states that the upgraded card works 
well with linux-wlan-ng

 I figure I will have to use 
pk0101010.hex (1.1.1 pri) and 
sf0107040.hex (1.7.4 sec) 
for this upgrade. Any comments ?

 junsun.net also refers to upgrading firmware at 
http://linux.junsun.net/intersil-prism/

  It does not cover prism2dl, which would have been helpful. 

regards..
Vikram
