Installing Linksys WMP 300N on Server 2003 Issue

Installing the Driver for my Linksys (Cisco) WMP 300N Network adapter, I kept getting an error. The installer requires you to install the utility on the CDROM before you install the PCI device. I was having issues for a Windows Server 2003 64bit system and I found that this has been an issue for many other people as well. After dealing with the customer service and tech support at Cisco and them stating profusely that I had no idea what I am talking about and that I do not know anything about the hardware since it “will not work on Windows Server 2003,” I did it myself.
What I found is that there are three versions of this adapter even though there is only one name and that they have chipsets from:

1 – Atheros
2 – Dlink
3 – Broadcom

I had the Broadcom version and the last time anyone saw it working was in 7/2007 with a disk from 10/2006. This being the case, I had to find a way to fix this. Every time I got half way through the process after rebooting the system, Windows would ask for me to install automatically, which is what you are supposed to do. And then, when it gets through the part where it asks if I want to use this driver even though it is not fully tested or compliant with the operating system I am using, it would ask me to locate the file: BCMWL564.SYS (This file is nowhere on the disk nor is it anywhere installed in a directory or anywhere else on your system AND you cannot get it from Cisco’s site where Linksys products now live).

Also, they do not support any old drivers or allow them to be downloaded from the old links out there. So, I went online and found bits and parts of files. I found a version of: BCMWL564.SYS. And I found a version of an old install disk with the whole driver setup file in it. (It was the last workable version). Neither of these alone did the fix.

I then went to the Linksys site and got the most current driver disk with the utility for XP, Vista and Windows 7.

And here is what I did. And this can be the set of steps you do as well.

I downloaded the files mentioned above. Here they are together:

1 – BCMWL564.SYS

2 –

3 –

And here are the steps I took to do the deed:

1 – I unzipped them all three on my desktop, which you can do as well. I then uninstalled all my previous attempts.

2 – I as well went into the device manager and uninstalled the whole adapter.

3 – I rebooted the system to clear the registry.

4 – I reopened the system and started the “setup” install from the

5 – It says to shut down the system and install the PCI adapter physically into the motherboard. So, I did that.

6 – I rebooted the system.

7 – Once Windows started the process to automatically install the wireless adapter, I told it to continue.

8 – When it threw up the request to locate from the CDROM drive the BCMWL564.SYS file, I pressed ok and then it opened up the “location dialogue”

9 – I then directed it to the following file on my desktop in the extracted folder:
C:Documents and SettingsYOUR USER NAMEMy DocumentsWireless Broadcom DriverWireless_Broadcom_4311_v4.100.15.5_XPWireless_Broadcom_4311_v4.100.15.5_XP

And I highlighted the bcmwl564.sys in that package. Once this was done, it went through the entire install and located the rest of the driver files for the package.

Restart and it worked!!!!!

Download the three files above I have on the system and enjoy!
