Re: Vista TCP

Native WiFi -- Correct. I just have something out of skelter. It might be
that I don't have some indication to NDIS set up just right. In the
indications, I've given NDIS: CONN_START, ASSOC_START, LINK_STATE,
LINK_STATE, ASSOC_COMPLETE, LINK_QUALITY, CONN_COMPLETE. These seem to be
working to establish an association and connection with the AP and since
static IP address let me xfer packets back and forth.

You write a native ndis 6 miniport, correct?

I'm having a problem with a 802.11n WiFi driver I am developing for Vista
(build 5384).

When I use a static IP address, everything works fine. However, if I use
DHCP, I don't get a DHCP address allocated to me from the AP.

I know DHCP in Vista 5384 works because I have a Realtek 8185 802.11g
card
that works OK.

Here are a couple of clues to the problem:

1. The first thing I found was that the driver was transmitting the DHCP
DISCOVER broadcast packet and then receiving a DHCP OFFER broadcast back
from the AP. However, the driver's packets filters were setup to handle
only DIRECTED (i.e. unicast) packets. This seemed a little strange,
since I
believe during TCP protocol initialization the driver should be called to
set the the MULTICAST and BROADCAST filters.

2. Thinking that perhaps I had a problem with the packet filters, I
jury-rigged the driver to accept all packets which then started
indicating
the DHCP OFFFER broadcasts up to the protocols. This did not work. TCP
still would not transmit a DHCP REQUEST packet to the AP.

3. Thinking that I still have a problem with the packet filters, I add
more
debug traces to the driver and rerum the test. PRESTO! Now I have a
valid
DHCP address from the AP. Strange. However, now I cannot ping the AP.

Anybody have any thoughts about this problem?
