Defective Ethernet cable
To check if the cable is working or not, try connecting the cable from one (1) port on the switch
to another and check if the corresponding LED port status indicators lit up. Otherwise, use
another cable to isolate the issue. Make sure that the cable is tightly inserted when connecting to
any of the Ethernet ports on the switch.
QUICK TIP: If you do not have an extra Ethernet cable, you may purchase from a local
electronic shop.
The Ethernet cable is not detected due to incompatibility
Some of the previous models of switches don’t have the capability to automatically detect the
type of cable being used; whether crossover or straight-through. If you have this type of switch,
a straight-through Ethernet cable is used to connect a computer to a switch or a router to a
switch. For switch to switch connections, a crossover cable is used.
NOTE: The numbered ports on the Linksys SE1500, SE2500 and SE2800 switches have auto
MDI/MDI-X (straight-through or crossover) cable detection capabilities. This means that you
can use any type of cable and it will automatically be detected.
Defective or disabled Ethernet adapter on the computer
Another possible reason why the light indicator on the port does not light up is because it does
not detect a connection from the Ethernet adapter on your computer. To check if the Ethernet
adapter of your computer is functioning properly:
Step 1:
Access your computer’s device manager by right-clicking the My Computer
icon on your Desktop and then select Manage.
