Hi,
I recently reinstalled windows7 on my dell inspiron n5010l laptop and have tried getting the wifi to work on it. For some reason, it can't connect to the internet when connected to wifi but in safemode it works.  Any ideas?

Don't have macafee at all. When I reinstalled the image it was from recovery partition but the drivers for Intel 6250 wireless were never installed so I downloaded from dell support.

do you have any unknown devices in device management?

I had unknown drivers under network adapters at first since I think I used the wrong drivers but once I instslled the correct one everything disappeared and the wireless adapter was listed correctly. I'm pretty sure if the driver was wrong that it would not work even in safemode. I will try the link you provided but it looks like it's the same one I downloaded from Dell site.

Is it possible that you are installing the wrong drivers for the dell.  
Dell has that autodetect feature on their website

I will try the cleanboot but the fact that it works in safemode isn't this essentially same as cleanboot? Going back to what I mentioned before, if a driver is incorrect then it shouldn't work even in safemode correct? I did use the dell autodetect to identify correct model laptop and supporting drivers. The wireless adapter is Intel 6250n.

In safemode you are not testing other software/driver compatibility problems that are loaded in the complete windows environment.
Safemode configuration looks at the operating system and says:  what is the minimal configuration I can use and still run.

If clean boot is a problem for you...
You might want to look into dells hardware diagnostics tests:

I am assuming that this machine worked correctly at one point in time.
Dell has it Proprietary software.... and procedures
Is this a reinstall or upgrade from vista..

After reinstall::::
They make a point of installing drivers in the right  order...

Yes it was working for a long time until just recently. This was a reinstall of win7 using the dell factory restore image which I have done twice in the past without a problem.

Just to make sure I understand...
Did you ever have a connection in normal mode with this new install....
Did you windows update this computer automatically or manual  from normal mode and then lose your connection?

Yes the wifi was working in normal mode for a long time then just started experiencing issues with it so ended up running the factory image restore from the dell restore partition. I've never seen this where a wireless adapter is working in safemode but not normal mode. In normal mode the wireless networks in the surrounding neighborhood are all detected and when I select my network it reports the connection as excellent in signal strength and states it as connected however it can't access the Internet. It even reports packets sent and received so there seems to be activity. Strange

I tried pinging several sites as well as pinging IP address of Google public DNS and none worked in normal mode. I could however ping my router.

I would also disable firewall temporarily and security software and see if you can access the net.
And I would reset your router..some router don't erase passwords .... the new ones.. which one do you have...I can understand if you don't want to answer that??

Yes but that rarely helps. It says everything is fine. My thought is to install virtual machine and see if wireless works from there in normal mode.

Navigate to the desktop.
Hold down the Windows key and press R.
Note: This will open the Run dialogue.
It actually could be dns also:
Type "cmd" and press Enter.
Note: This will open a command prompt.

Type "ipconfig /flushdns" and press Enter.
Type "ipconfig /registerdns" and press Enter.
Type "ipconfig /release" and press Enter.
Type "ipconfig /renew" and press Enter.
Type "netsh winsock reset" and press Enter.
Reboot the computer.

Yes hardwire cat5 no problem. It's not DNS issue since I couldn't ping 8.8.8.8 for Google

Yes that's correct, I could not ping 8.8.8.8 so then I knew it was not a DNS issue.
