ok here is another thing that just happened last night.

I was taking all of the advice in this thread into consideration, and was
checking everything and going back to my starting point. I opened network
connections, chose wireless network connections (my laptops connection to the
router) and then clicked properties. i think scrolled down to the bottom
choice, i forget the name right now, as i am not on my computer it was
something like icmp icl or something like that, but then i clicked the
advanced tab in it and then clicked settings on the first option, which
brought me to an allow these networks to be assigned ip addresses, and my
xbox wasnt checked, so i checked it. i tested my connection to xbox live and
it worked, i was playing for a while and then it stopped again, telling me
the dns couldnt resolve my IP address. so i tried everything over and
everything was the same as it was when it was working. i tried repairing
connection, refreshing IP's, and resetting connection, and then the IP

Try a google search for "double natting" if you want to read up on
your problem. It can be made to work the way you are attempting to do
it but it is both problematic and inefficient.

A computer will normally get its DNS nameserver information as part of
the dhcp protocol at the same time as it gets its ip address from the
router.

If you uninstall ics from the laptop and bridge the wired and wireless
interfaces (as stated previously) then both the laptop and xbox can
get their ip addresses and nameserver information from the router and
everything can work simply. Problem solved.

If, however, you insist on using ics on the laptop, then it cannot get
an ip address and nameserver information assigned by the router so you
must configure everything on the laptop manually. It will have a
static ip address of 192.168.0.1 which you can't change and you need
to enter your isp's nameserver ip addresses into the relevant boxes in
the tcp/ip properties. If you don't know the nameserver addresses then
try it with 208.67.222.222 and 208.67.220.220 which are opendns
servers.

With ics you also have the original problem of networking the laptop
with your router whose default is on a different subnet and so has to
be changed to something on the subnet 192.168.0.0/24 without clashing
with other equipment on the network. Review MVP Malke's instructions
earlier in the thread on how to do that.

Confirm test failed again. I checked my settings and they were the same as
before, so far that i can tell. but now, my XBOX live doesnt work, and when
i turn the XBOX on and it is connected to the computer, my internet doesnt
work, and when i turn off the XBOX, my internet works. i dont get that.

That's likely because the gateway information is screwed up and when
the xbox is on, the wired adaptor is active and the laptop will try
and use it in preference to the wireless to get out to the Internet.
When the xbox is off the wired network adaptor becomes effectively
unplugged/disabled so the laptop uses the wireless adaptor to get out
to the Internet like it's supposed to.

You really are making a rod for your own back persisting with this ics
nonsense. The reason for all the posts about static ip addresses are
because you weren't specific enough in the first instance about your
network and the mvp's and others were relying on clairvoyance and
guesswork for most of the assistance.

You will be advised to set up a wired/wireless bridge and ditch ics.
