If you are reinstalling Windows or updating all drivers, it is important that this software be installed first. This is located under the System and Configuration Utilities Category on the Drivers and Downloads page.

Desktop System Software (DSS) or Notebook System Software (NSS) - A vital utility that provides critical updates and patches for the operating system.

Dell systems have a particular order in which the drivers need to be installed. So if you just get online support and tell them, they will link you directly to the driver you need. Otherwise Dell has great online support (at least IMO). You might try this link and see if one of these drivers solves your issue. Every time I need it I have to hunt it down again. In HP's case they do not seem to keep this with all the other driver for a particular model, but somewhere off by itself (perhaps it is common to all models). I nmy case I beleive it is related to the AHCI driver. So it might be a parallel situation (or completely unrelated).

Thanks for responding! I have a similar experience on some HP boxes here. I'm not sure if this missing driver will have anything to do with the low signal strength I am getting from the wireless adapter, but that is the main problem I am facing. I used a tool called Unknown Device Identifier also, to figure out which drivers were missing and it's still showing that the PCI Comm, Controller is missing a driver. Not sure why it excluded this one in particular. Thank you in advance! Yes there is and I attempted to use this tool, however, it only provided me with the Ethernet Controller and Graphics card driver updates. Sorry this is a question 1a and 1b scenario. Is there a way strengthen the signal from the router or from the Linksys Wireless adapter on the computer its brand new. I am using an Encore Wireless Router in the upstairs portion of a home and the wireless signal reaches as far as the office downstairs but the the connection is very slow. I was able to install drivers for all of the hardware components except I could not find the drivers for the 'PCI Simple Communications Controller' Could someone help me locate this driver? I think this missing driver may be contributing to an issue with the PC's ability to connect to the internet at full strength. Hello, I recently reinstalled the OS on a Dell Optiplex 755 and unfortunately, I don't have the drivers disc for this computer.
