How to Solve Network Card is not Installed Successfully?


General cause of the network card is not installed successfully may be that the network card driver does not interrupt number or I/O value does not and network cards hardware failure. You can be detected according to the following steps:


1. Such network cards are generally factory was set some default values, these values include "interrupt" (IR Q value) is "3", "I/O address range (I/O) is 300-31F", you can double-click the card name here, to detect whether these values has been modified, if not, please correct (correction need to restart the computer).

2. If the above is believed to be correct, and the network cards still does not work (i.e. the front there is a yellow exclamation point), please re-enter the "Device Manager" tab, expand Ports (COM LPT), if there are communication port (COM2) the presence of the word, you also need to shield the COM2 port. Because the defaults COM2 port will occupy interrupt No.3, so that the initial value of and NE2000 compatible family network cards conflict, so the network cards does not work. 


Operation, restart the computer, press the "Del" key on the keyboard to enter the CMOS when the computer restarts, follow the prompts, then Intergraded periphery A LS item, select the "Onboard Serial Port 2", then press on the keyboard "Page Up" key to re-election to "Disable" (disabled) press the "Esc" key to return the CMOS main menu, press the "F10" key to save changes made to restart the computer.


3. If it is or not, I suggest right-click and choose "delete", and then restart the computer, and re-strict step-by-step to add this network cards.


4. The next attempt, you can replace the network cards slot to try.


5. If it still does not work, then either the network cards is not NE2000 compatible series, either the card itself is faulty.


6. Of course, if someone modified the fiber network cards interrupt number and I/O values that you use the default value of nature is not, therefore, to be safe, you can find this network cards complete installation the setting disk, run inside the setup program, check its default value, if there are different re-based on the new value to be modified; when you run the setup program, the system prompts can’t find the relevant network cards, is your card is not inserted, or where slot or the network cards hardware failure.
