Q. How do I know if my network card works.

A. Every card has an .EXE file on the floppy disk that comes with the
product. 

This has many different names, but basically runs a diagnostic program
to test the network card.

You should run the EPROM TEST and the CARD TEST remembering to
attach resistors if you are testing using a BNC connector, and a hub or
crossover cable if you are using UTP.

Q. My network card crashes Intermittantly

A. This is usually the case when IRQ 9 is used by the network card.  We recommend the use 
of a more stable IRQ such as 3,5,10,11,12. As the network card is Plug and Play, you cannot force
windows to use another IRQ. To get around this you disable IRQ 9 in the bios.

In order to change IRQs for your network card, you will need to carry out the 
following steps below;

	- Go into the bios (press del to enter setup or whatever key quoted on screen) 
	  now go to the PCI section and set IRQ 9 to "Legacy ISA" Also ensure that
	  "pnp aware os" is set to yes and save and exit (usually F10).

	- You will now need to go into SAFE mode(press F8 during boot) and select 
	  option 3. "Safe mode" will be displayed around the four corners of the desktop.
	  Go to Control Panel > System > Device Manager > Network adapters and remove the 
	  10/100 Network card. 

	- Go into My Computer > C drive > C:\windows\inf and delete the filename netrt.inf 
	  & netrtf.inf then go into "other" directory. Now remove the file that is called 
	  "RealtekNETRTS5.INF"

	- Now restart your computer and reinstall the network card.

Q. Windows does not detect my network card or gives an error at startup

A. To troubleshoot network cards, run the diagnostic utility that can be found on the driver floppy disk.  The program is usually named RTL8019.exe or ezcfg.exe and may be located in the root or a directory called DIAG.

Run this application to determine the current setup and resource usage of the card.  If it is an ISA card, it may be necessary to change the operating mode to jumperless instead of PnP.  ISA cards will require legacy resources and may require the chosen IRQ to be set to Legacy ISA in the PnP section of your system's BIOS.  The most common resource setting is I/O 300H and IRQ3 which will require the on-board serial port 2 to be disabled.

Q. I can't contact a remote computer via my network card although local network functions work.

A. Pinging 127.0.0.1 will return a valid PING providing that TCP/IP is installed because it does not transmit any packets to the interface, it is purely an internal loopback test.  You have to ping a remote address to test the interface.

Q. When I connect my cable to the card, the LNK light does not come on

A. Your coax cabling may not produced a LINK LED if it is damaged or incorrectly terminated.  The simplest way to test this interface is to connect a T-piece with 2x 50ohm resistors to the BNC post.  The diagnostic program offers an external loopback test.

It is not possible to connect transmission media to both jacks at the same time.

Q. The diagnostics program does not on Windows NT4

A. The diagnostics probably failed within NT4 because direct access to the hardware is not permitted by the Operating System.  Unfortunately such access is required as a call cannot be made via the driver because it is not usually installed at this stage.  It is recommended that you use a machine with Windows 9x installed and restart in MSDOS mode before running the test.
