Lattitude E5510 - network driver update - Installation Blocked

Hello,

          hoping someone had run into this issue. We have a Lattitude E5510 that is having disruptions in connectivity. It will just freeze when in IE after a few minutes of use.  I don't see a ton of network activity showing on the Laptop or a bunch of RAM getting used. The interesting thing is that other programs can be run at that time, as long as they don't require internet (Windows Update will also occasionally fail). Scans on the machine come up clean. Apparently this problem has been occurring since the laptop was new.

I figured this might be a driver issue. Current version showing in system manager is Intel Centrino Advanced-N 6200 AGN  13.3.0.24

The only Wifi driver update I see for WiFi on Dell's support site for 32 bit Windows 7 is: WiFi Link 6200 v15.10.0.10 (A03). I don't even see any previous versions listed.

I downloaded the above driver and ran install and it gives me this error message:

Installation Blocked
Intel Proset Wireless Software v16.1  This version cannot upgrade from the current older
Please uninstall the older module manually.

So before I go into Control Panel and uninstall the previous version of Intel ProSet, do I have the correct version of the driver? Anything else I need to do besides an uninstall from Control Panel or should I need to do any kind of specific folder cleanup to make the install work?

I have never gotten a notice like this when installing a driver which makes me think its not compatible.

Any help in the right direction would be appreciated.
