tcpip.sys download.
I cannot say that its safe to replace yours.. But if you are desperate for one that worked for me(YOU NEED TO RESTART AFTER... If you are lazy to restart try shutdown -f then..):

It looks like screwing up tcpip.sys FRIES WebClient Service needed for the internet.
I had the same problem. Deleted c:\windows\system32\drivers it worked.
Before
ping 127.0.0.1 wouldn't work
my wireless said "ASSOCIATING"
and internet explorer said the adress type is invalid and showed me some /// stuff.
On a dell inspiron 6400.
This was due to BITCOMET which created a tcpip.sys.ORIGINAL..Just for those of you in DANGEROUS SITUATIONS, where you only have 1 computer I HIGHLY RECCOMEND you make a copy of tcpip.sys in c:\ so that if you ever have this problem again you can easily fix it
So in Summary
===========================
Problem
-Internet not working.
Symptoms with wireless on my Dell inspiron 6400
- Internet Connection icon does not show the connecting ... state
- Having BitComet ..or other tormenting problems installed..and changing the IP Configuration settings there
- Associated shows in my tray icon
