Problems with N5010 wireless

If the notebook is able to see and connect to your Iphone it is likely that the wireless card on the notebooks is fine.  I would check to see if your wireless router is set to broadcast the SSID.   Here is a link to a good basic troubleshooter for connecting to wireless networks.

• 1. Make sure the wireless switch is on. It will be either a sliding switch on the left or right side edge of the computer, a key combination or single key, look for the wireless icon

• 2. Move the computer to within 10-20 ft (1-3 meters) of the router.

• 3. Make sure the correct network name (SSID) and key (if any) were used to create a profile, for more information refer to the How Do I Find my Wireless Network Name and How Do I Find my Wireless Network Key sections.

• 4. Unplug the wireless router for 30 seconds and then plug it back into the A/C outlet (give the router 2 minutes to boot back up).

• 5. Run network diagnostics (refer to the My Internet Explorer Browser Cannot Display the Web Page section for information on how).

• 6. Make sure the latest driver is installed:

• 7. Update the wireless router's firmware to the latest available, refer to the wireless router documentation or contact the wireless router manufacturer

I hope that this helps
