<BODY>
<P><FONT SIZE=2>Thank you for your reply.</FONT>
</P>
<P><FONT SIZE=2>I have a card with STA firmware 1.7.4. After I read the reply,</FONT>
<BR><FONT SIZE=2>I tried some more tests, and got the right beacons.</FONT>
<BR><FONT SIZE=2>The first byte is the length IE, not frame type.</FONT>
<BR><FONT SIZE=2>I still don't know what the second byte means. But zero value</FONT>
<BR><FONT SIZE=2>of the second byte made tests successful.</FONT>
<BR><FONT SIZE=2>The rest 26 bytes from the third are WPA IE.</FONT>
<BR><FONT SIZE=2>My successful codes are something like followings.</FONT>
</P>
<P><FONT SIZE=2>char buf[28] = { 0x1a, 0x00, 0xdd, 0x18, ....}; // 0x1a==26</FONT>
<BR><FONT SIZE=2>local->func->set_rid(local->dev, HFA384X_RID_GENERICELEMENT, </FONT>
<BR> <FONT SIZE=2> buf, 28); </FONT>
</P>
<P><FONT SIZE=2>> I have checked the codes you mentioned. </FONT>
<BR><FONT SIZE=2>> And I think you can write the codes like this: </FONT>
<BR><FONT SIZE=2>> char buf[26] = {0xdd, 0x18, ...} </FONT>
<BR><FONT SIZE=2>> local->func->set_rid(local->dev, HFA384X_RID_GENERICELEMENT,buf, 26); </FONT>
<BR><FONT SIZE=2>> > ~~~I think 26 </FONT>
<BR><FONT SIZE=2>> should be (26+1)*2. I donot know about it exactly, pls just try it.^_^</FONT>
<BR><FONT SIZE=2>> You need not to tell firmware about the frame type of WPA, because RID FC48 is </FONT>
<BR><FONT SIZE=2>> just for WPA IE, firmware knew about it. I set IE in AP and sniffed frames, </FONT>
<BR><FONT SIZE=2>> it's good.</FONT>
</P>
<P><FONT SIZE=2>>>char buf[28] = { 0x80, 0x00, 0xdd, 0x18, ....}; </FONT>
<BR><FONT SIZE=2>>>local->func->set_rid(local->dev, HFA384X_RID_GENERICELEMENT, </FONT>
<BR><FONT SIZE=2>>> buf, 28); </FONT>
<BR><FONT SIZE=2>>> </FONT>
<BR><FONT SIZE=2>>>The first byte of 'buf' is the frame type of beacon, and 26 bytes from </FONT>
<BR><FONT SIZE=2>>>the third to the end are WPA IE. </FONT>
<BR><FONT SIZE=2>>> </FONT>
<BR><FONT SIZE=2>>>I caught the beacon frame in the air, and saw the IE is attached. But </FONT>
<BR><FONT SIZE=2>>>102 meaningless bytes are attached in the trail also. </FONT>
<BR><FONT SIZE=2>>>I don't know the right procedures to configure IEs in management </FONT>
<BR><FONT SIZE=2>>>frames. I just tried, but it is not successful. </FONT>
<BR><FONT SIZE=2>>>I guess, if we know the right configuration procedures of f/w 1.7.x, </FONT>
<BR><FONT SIZE=2>>>we can make HostAP to support WPA.</FONT>
