I have a LAN port cable, and I have one end connected to the back of my router. Where does the other end go, so I can receive wireless internet connection of both my Toshiba Satellite Laptop, and Gateway Desktop. First I had the LAN port cable connected at the back of my router, and the other end was connected at the back of my desktop. A little green light lit up at the back of my desktop, saying that it was grabbing signal. I could use the internet fine, and my laptop could grab wireless signal fine as well. I was missing around my router, trying to see what mark it was, and the LAN port cable came off, and when I plugged it back in, i couldn't receive signal, and neither could my laptop. Now the only way I can grab signal is by connecting the WAN port cable from my modem to my desktop, which means I cant get wireless signal on my laptop. Now when I do connect my LAN port cable to the back of my desktop, I try connecting to my wireless connection, and when I go to Network and Sharing Center, it says Connected (With full bars). But when I try to go online, it says Internet Problem/Connections. In the bottom of the name of my router it says"No Internet access."
