5-port switch question

I am using the above mentioned switch. I have a CAT 5e
cable connected to my wireless DSL port and into the
switch. I have two other CAT 5e cables - both are
attached to the switch and one goes into a laptop and the
other goes into a PC.

The three lights on the switch are not all lit up for the
port that goes into my DSL. Should they be? They only
one that is lit up is Link/Activity light. The Speed and
Full-Duplex lights are not lit up.

I tried changing the cable, still not all lights are lit
up. I am having trouble with my laptop, it does not seem
to be getting the full 100 mpbs speed that it should -
I'm wondering if it is because of the lights not lit up.
any help would be greatly appreciated. thank you!!
