How to check whether your LAN CARD is working or not... (Without connecting it into a computer)

All you need : One lan card and one multimeter or continuity tester.

[Remark: Dear friends this solution is what I find myself so anything wrong with this please comment here to make it better]

Please see the following pictures. On each picture the pin numbers (there are 8 pins marked from 1 to 8)

Back panel view of your LAN Card

Top View of your LAN Card

Bottom View of your LAN Card

A perfectly working LAN card shows continuity between the following pair of pins

1 and 2

3 and 6

5 and 4

7 and 8

So set your multimeter knob to continuity and connect its terminal lead to pin number 1 and 2 if a continuity is there it will beep or shows a continuity if you are using a continuity tester( which is cheap in cost than a multimeter) its light will turn on. Similarly check the continuity between the pins 3 and 6, 5 and 4, 7 and 8. If it shows discontinuity between any of the pair say 3 and 6 then you can identify that it is a faulty LAN card.
