I have one computer on the internet what do I do toset up a wireless router for second computer?

In the picture, it looks like a wireless router. In that case, his computer just needs a wireless card to get the internet. Or, you can hard wire it directly from the modem to the computer, if you don't have a wireless card for the computer.

You will need to check the wireless settings of the router
is there any computer connected to the router ?
If yes then you can open the router set up page on that computer.
Router set up page is the page where you can check all the wireless settings of the router.

The second computer's wireless card may not have the latest wireless card driver installed or it is not enabled and working. Check Device manager to see if is is working and enabled. I suggest you install the latest wireless card driver.
Next check the wireless card configuration, it needs to have the wireless router's settings, ie SSID and encryption etc.

Have you already setup one of your computers to connect to the Internet using the wireless router?
If so you can setup the second computer the same way and it also will connect to the internet. There is no need to access the Internet through the other computer.

Remove the power cord from the router. Wait 30 seconds. Reconnect the cord. Like rebooting a balky computer.

You may also have other routers nearby on the same broadcast channel.

Occasionally cordless 2.4ghz phones may jam the wireless channels.

Chose another channel from the router setup.

SSID number is the security key that you have to protect your network from unauthorised usage.
you can easily get it from your router vendor.
