Can connect desktop to internet but having trouble connecting laptop to internet

The wireless card may be swithed offGo to control panel and select "wireless connection" windows will detect the wireless card and tell you if it's swithed off.

Do you need to see the desktop or just share folders from each other? If the latter then you need to do the following:

Use Windows Explorer and select a folder you want to share. Right click and select sharing and security.

On the sharing tab click on Share this folder. Enter a share name ( I like to enter the PC name _folder name; Rick1_Downloads)

Click on Permissions. If your ok with everyone using the PC's and Laptops having access then highlight Everyone and click on Full Control.

Do this on each PC and Laptop.

That should be it or darned near close.

try this plug up a line to laptop to modem to check to see if you can get connected if so then make sure you are on the same network and if so then call comcast to help you setup the laptop wireless settings in sound like the settings online doesn't have the laptop enable to accept the laptop

If you disconnect the desktop from the modem, were you able to get an Internet connection in your laptop?
In order to get Internet connectivity on your desktop at the same time with the laptop, then the desktop needs to be connected to the router. It should be connected to one of the Ethernet ports at the back of the router. Since, your desktop doesn't have an Ethernet port, then you need to connect a USB to Ethernet adapter to your desktop. Then from that adapter, you will connect to it an Ethernet cable going to the router.

You may check the following models:
Linksys USB200M
Linksys USB100TX
Belkin Gigabit USB 2.0 Network Adapter(F5D5055)
D-Link DUB-E100

There are other brands that offer USB to Ethernet adapters that you can check.

Hope this helps!

The trouble is with your metwork connection through which the Laptop connects to the Internet. There is no proven way to increase the speed of connectivity. You may check your connection speed from the two-computer icons on the bottom-right corner and determine the speed. A speed of 2 mbps or more is ideal for viewing videos on internet.

when you put the mouse over the network icon in your taskbar, it will say access: Local & Internet or local only.

if Local & internet you have a connection to the internet, if local only then open internet explorer, tools, internet options, connections and check that there is no default connection, it should be never dial a conection thats ticked or greyed out.

Are you saying that your desktop is connecting to your internet connection but the laptop is not? Does your laptop connect to your internet connection wirelessly? This will go a long way toward helping help you better! Let me know I have some trouble shooting steps you can try!

Install the wireless adapter to the laptop and then search for wireless connections. Find yours and connect. If this is not what you are having trouble with, or this did not solve your problem Tell me and I will give you other troubleshooting tips.

Hope This Helps

You need to contact your ISP if the internet connection is not there....

you need to set up the internet connection in your router, to do this enter the router's IP address into your internet browser, then press enter (by default it should be 192.168.2.1) This will take you to your router settings page, be carfull what settings you adjust. their should be a section to set up an internet connection (it might be under WAN connection) you will probbably need your username and password given to you by your ISP.
