compared the packets on opposite sides of the wireless. What I compared was a
wired packet vs. a wireless packet, both at the client interface. I could
not find any difference in the two which lead me to believe it is something in
the client. Possibly the wireless hardware doesn't see the broadcast? Doesn't
make much sense, but it is all I can come up with at this
point.</FONT></SPAN></DIV>

actually talking about the infrastructure piece. But if you see it coming
out of the AP toward the client, then I can’t imagine it’s the

<P class=MsoNormal>I have a rather strange problem that I hope someone can help
me with. This is a general DCHP issue as I am not sure what software the server
is running.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>We have several Vista clients that are not able to get
an IP address when trying to connect wirelessly. They connect just fine when
wired. The DHCP server is the same machine. I have done packet captures for both
wired and wireless. I can see the DHCPREQUEST go to the server and I can see the
DHCPOFFER come from the server. The server logs confirm the request and offer.
In each case (wired and wireless) the DHCPOFFER looks identical. The only
difference is that when wired the computer responds to the DHCPOFFER and does
not respond when wireless. I have not seen any correlation with the brand of
adapter, but that could be because we have not looked for one.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>The only way we have found to resolve this issue is to do the
Vista registry fix to turn off the broadcast flag in the DHCPREQUEST for the
wireless adapter (KB 928233). While this will work, it means that any student
who wants to connect to the wireless AND has Vista will need to bring their
computer to our office to have the fix implemented.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>Has anyone ever seen this issue and found another way to
resolve it?<o:p></o:p></P>
