Unable to connected to internet

[joshev]

with me i had the internet working fine on my computer wich is wired internet to my modem D-Link wireless router with four ethernet cable slots in the back so i decided to take my ps3 downstairs and i plugged it into the router with a spare ethernet cable and it was working fine then when i was done i plugged my ps3 out and put back upstairs and i tried to go on the internet on my computer but it wouldnt connect to the internet and as before on my modem the LAN slot 1 would light up a desktop screen on the modem but now theres nothing no lights or anything and my computer is saying its not connected to the modem wich it is connected through a ethernet cable the router came with please help.

Have you tried turning it off and on again?

My D-Link used to lock-up frequently, and I'd have to power cycle it to get it to snap out of it.
