HP Pavilion laptop will not connect to the internet

HP Pavilion dv6t-7000 with W7.  There is no Ethernet port on this system.  Wireless is the only connection method.  The system will see my access point (all other of my systems connect fine) but will not connect to the internet.  I've done all of the "usual" stuff and do not want to list them but none worked.  These actions were extensive.  Interestingly, I was able to connect via Safe Mode which implies something is causing the problem when booting in "normal" mode.  A clean boot allowed me to boot and connect but even though I added one start up item at a time, and finished adding them all (checking each time if I had a connection), upon a restart, I was back to zero.  

I'm doing another regen from the factory image.  BTW, I tried to use a restore point before the updates from my previous regen but that did not allow me to connect either. The wireless adapter seemed to work fine but after doing the first set of 169 MS W7 updates, I have the same problem.  No connection to the web.  Is there a way to determine which of the 169 updates are associated with the Atheros AR 9485 adapter?  That may not be the issue but I'm at a loss of what else to try.  

One thought...if we purchase a USB wireless adapter, is there a chance that this will work?  The system is too good to toss.  It has a nice i5 processor, plenty of memory and a 750 GB drive.

Try TCP/IP Reset:

Open cmd.exe with Run as Administrator
Then  netsh int ip reset c:\resetlog.txt
Also, ipconfig /flushdns followed by net stop dnscache followed by net start dnscache
Then restart the computer

Try System File Checker:  Open cmd.exe with Run as Administrator and run SFC /SCANNOW. Allow to complete, shut down. start up and test.

Try replacing the wireless NIC driver.

Then try both a new USB Wireless card and a USB Wired Ethernet Card and test both.

Thanks John, per my undefined list of things that I didn't mention but already tried, it included all of the above you've listed.   The SFC did show some issues which could not be fixed which led me to do the regen.   I also replaced the NIC driver.  That didn't fix it either.  I do see a newer version from the Czech republic and was thinking of trying it.  It looked legit.  

I've already done a regen....again.  This time, I was going to look at each of the updates to see if any one of them is associated with hardware before doing the updates and if so, was going to remove it from the update process.   Does this make sense to you?

I have never had a machine that would not use the Internet because of updates. Never happened.

You should get NIC drivers from HP not Czech Republic.

You can try removing updates but I do not think that will affect Internet unless something else is wrong.

I would try a new card because you are on your 3rd reimage of the machine.

I was able to find an old WUSB54G adapter.  I found some drivers that I think will work with W7.  I installed them, and removed the drivers for the integrated wireless Atheros adapter.  Got connected with good signal.  Shut down the system and it has reconnected just fine.  I think I'm getting confident that the Atheros integrated adapter is bad.  What do you think.  If this is still working OK in the morning, I think we can close this one out.  I'll just buy a new USB (updated) adapter and say the heck with it.  I've chased this one down enough.

I agree with trying a new adapter. I used to use Atheros (XP) but after that they were not any good and I have switched to Intel myself and for clients.

I'm installing the first wave of 124 MS updates.  It will be interesting to see if I still have a connection after the install.  I'm betting YES and if so, I'll call this "fixed" and blame it on a malfunctioning integrated adapter.
Out of curiosity, did you try changing the broadcast channel on the AP?
I had the same issue with a lenovo win 8 tablet and my home router once. Drove me nuts. Changed the broadcast channel on the wifi and boom, the stars aligned and I was online.
tonyadamRetiredAuthor Commented:
sloutz....no, did not change the broadcast channel.  This same behavior was occurring on a completely different router so I'm guessing it would not have helped.

I  believe that the integrated Atheros AR9485 wireless adapter was not functioning properly.  I would work for a few minutes and then not work.  The inexpensive solution was to purchase a USB wireless adapter which solved the problem.
