Alan,
The DPC latency created by the wireless card is not necessarily the
drivers, but the delay of the additional security overhead of the
wireless links, but also your firewall is most likely doing more
filtering of the packets coming from a wireless link.. There is not
much you can do about all this, short of adding a much faster
computer.. I have been told that gamers use a wired link to a wireless
link device that does all the security work so your computer doesn't
have to..
I like Tim's ideal, use a fiber link, I think that there are some 802
to fiber adapters you can run fiber in between..

For me it seemed like the DPC's were consistently a little higher.
So since I had a choice between 3.....
I think it is just because of the way I do things. Not always logical!
Anyway I hope that both of our systems continue to perform well.
Way back when, when the shack computer was running WinXP, I tried
using a Linksys USB Wireless-G adapter because I didn't want a wired
network connection violating the lightning protection. It was slow, so
I used the wired connection anyway.
About a month ago we got a major lightning hit that charred the serial
card to which the rotator controller was connected, killed the 3.3V
line on the power supply and took out a bunch of networking devices
throughout the house -- including the wireless router. (All this
despite the PolyPhaser lightning protection.) The 5K antenna
connections were all grounded at the time, and it was unscathed.
I put together a new shack computer with Win7, replaced the Linksys
router by a D-Link Xtreme N, and tried using the Linkys USB adapter
again. This time it was not merely slow but kept losing the
connection, and the general opinion on the 'Net is that this device
does not work with Win7.
I bought a D-Link PCI-Express Xtreme N card, which was delivered
today. It seems to work OK, BUT I kept getting major DPC spikes and
had to run the Firewire driver in Safe Mode 2 to avoid garbled audio
even though the driver utility recommended Safe Mode 1. Google turned
up a reference to a far better driver (from Atheros, the chip maker)
than the one installed by default), but I still have to run in Safe
Mode 1.
