<DIV><SPAN class=924461102-30042003><FONT face="Courier New" size=2>One of
the major issues is that they don't _appear_ to implement standard TFTP - it
looks like a slightly whacky variant, which doesn't speak well for it fully
implementing TFTP (eg: GET as well as PUT).</FONT></SPAN></DIV>
<DIV><SPAN class=924461102-30042003><FONT face="Courier New"
size=2></FONT></SPAN> </DIV>
<DIV><SPAN class=924461102-30042003><FONT face="Courier New" size=2>The main
hurdle is finding a working copy of the firmware. I don't know if you found
the same thing, but the ethernet port appears to completely die when you
flash them with Linksys firmware, which makes further TFTP flashing somewhat
difficult. However, the linksys USB client appears to flash it
fine.</FONT></SPAN></DIV>
<DIV><SPAN class=924461102-30042003><FONT face="Courier New"
size=2></FONT></SPAN> </DIV>
<DIV><SPAN class=924461102-30042003><FONT face="Courier New" size=2>The best
bet that I can think of is reverse-engineering the USB interface to it (I
imagine it would be quite simple) and seeing if you can read the firmware
out this way. I have had success doing this sort of thing with DSL
modems in the past (albeit via serial ports), but the principle is much the
same.</FONT></SPAN></DIV>

moment, but if anyone knows of good USB sniffing software, or a good way to
do this - it would be most appreciated.</FONT></SPAN></DIV>

Melbourne Wireless<BR><B>Subject:</B> [MLB-WIRELESS] SVEC FD1811 (aka
WLAP) Firmware<BR><BR></FONT></DIV>
<DIV><FONT face=Arial size=2>Hi all,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have a SVEC FD1811 AP which is rather sick
since I flashed it with Linksys firmware. So to try to nurse it back
to health I've been trying to find any firmware which will make it work
again. I've noticed that the SVEC FD1811 has many twin (ie rebadged)
brothers sold by different suppliers. But none of them offer a
firmware download. The SVEC AP, like many other APs out there
(including the Linsys WAP11 v1) uses the Atmel AT76c510 chipset.
Today I think I found an important difference between the SVEC and most
other 510-based APs.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I found this site:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2><A
href="http://www.toptrend.com.tw/Technical%20support%20for%20WLAN-1.htm">http://www.toptrend.com.tw/Technical%20support%20for%20WLAN-1.htm</A></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>As far as I can tell, Toptrend write the
firmware for the Atmel 510-based APs. Most of them have Intersil
radio chipsets in them. I guessed this by looking at the firmware
version number on the page above. But the SVEC FD1811 (and I assume,
all of the rebadged SOHO-WLAPs out there) use RFMD radio chipsets.
The version number of the firmware listed on Toptrend's site is the same
as what is in my other, still working SVEC AP: </FONT><FONT
face=Arial size=2>V0.0.1.16</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So can anyone suggest how I might get a hold
of this firmware? It isn't available for download anywhere.
SVEC won't send it out. I'm goint to email Toptrend and
see if they'll send it to me. Jamie Moir and I have tried
to extract the good firmware out of a working SVEC AP using TFTP but
with no success. That's not to say it isn't possible though. Is
anyone willing to devote a bit of time to tinker with my malfunctioning
AP?</FONT></DIV>
