Troubleshooting
4 Make sure that no electromagnetic interference, like
unshielded speakers or appliances on the same circuit, is
affecting your network.
5 If you are using a hub, router, or switch, make sure that
your network cables are not plugged into a dedicated
Uplink port. The Uplink port is only used when connecting
your hub to another hub or switch.
Understanding indicators
Your adapter has two indicators or lights labeled 100M and 1000M on its
back plate. They can give you information about your network traffic and
help you determine problems when troubleshooting.
• A steady green light of 100M indicates a good connection
at 100 Mbps.
• A flashing green light of 100M indicates that the network
adapter is sending or receiving data at 100 Mbps.
• A steady green light of 1000M indicates a good connection
at 1000 Mbps.
• A flashing green light of 1000M indicates that the network
adapter is sending or receiving data at 1000 Mbps.
Pinging your adapter
PING (Packet Internet Groper), is a utility to determine if a specific IP
address is accessible. It works by sending a packet to the specified address
and waiting for a reply. Ping is primarily used to troubleshoot Internet
connections. By sending out a PING, you are verifying that a specific
computer is available. Because all computers on the network must have a
unique IP address, a reply means that a computer is on the network and
that it can communicate.
