6 Troubleshooting
6.1 If you cannot connect your adapter to the network,
Verify that the communication mode on adapter matches that on Link
partner (such as hub/switch).
If the adapter’s communication mode is set to full duplex mode, make sure that the link
partner’s communication mode is also set to full duplex mode. If these are set differently, it
may cause lower performance, loss of data, or the connection.
For example, while a switching hub’s LAN port is set to Auto-Negotiation mode, if the
adapter’s port is set to full duplex mode, the switching hub’s port becomes half duplex mode.
Here, the link is established between them, however, the network performance will
extremely be low.
Verify your cable is connected properly.
The network cable should securely be attached on both LAN ports of adapter and link
partner (such as hub/switch).
Verify your cable type.
If your twisted pair cable is below the category’s specifications, (see Chapter 3 “Network
cable connection” on page 43 for details), or if it is damaged, extremely bent, or stressed
under a heavy object, communication may be disabled.
Also, if the cable is longer than 100 meters, communication may be disabled.
In such a case, try another cable.
Verify your driver is proper.
Verify you are using the driver that came with the adapter.
The driver file name contains “E1000” (e.g., E1000NT5.SYS).
