Introduction
When you use the Windows for Workgroups version 3.11 ELNK3.386 driver, your system may stop responding (hang) when it encounters non-802.3 packets. This problem typically occurs on extremely congested networks that contain a variety of packet types, especially non-NetBEUI packets.

The WG0990 disk included with this Application Note contains a new ELNK3.386 driver to correct this problem. The new driver correctly handles unknown packet types in heavy network traffic situations.

To install the new ELNK3.386 file
 Quit Windows for Workgroups.  Make a backup copy of the currently installed ELNK3.386 file by typing the following at the MS-DOS command prompt and then pressing ENTER ren : \elnk3.386 elnk3.old where : is the location of your Windows SYSTEM subdirectory. For example, if your Windows directory is called WINDOWS and is on drive C, type the following at the MS-DOS command prompt and then press ENTER: ren c:\windows\system\elnk3.386 elnk3.old  Insert the enclosed WG0990 disk in the appropriate floppy disk drive.  To copy the file to the Windows SYSTEM subdirectory, type the following at the MS-DOS command prompt and then press ENTER copy :\elnk3.386 where is the floppy disk drive containing the WG0990 disk and is the drive and directory of your Windows SYSTEM subdirectory. For example, if the WG0990 disk is in drive A and your Windows directory is called WINDOWS and is on drive C, type the following at the MS-DOS command prompt and then press ENTER: copy a:\elnk3.386 c:\windows\system
