Hi Jerome,

Is any other system/device able to detect your home network? If so, try doing a network power cycle-

1. Shut down the system.
2. Power off the Router.
3. Power off the Modem and wait for a minute.

Note: In some cases, modem and router are combined in a single device.

4. Restart the Modem and wait for 30 seconds.
5. Restart the Router, wait for another 30 seconds.
6. Start the system.

If it still does not work, try deleting the wireless network profile on the system and then connecting again. The steps to delete the network profile are:

1. Click Start > Control Panel. In the search box, type wireless, and then click Manage wireless networks.
2. Right-click the profile for your wireless network and click on Delete.
3. Click OK.
4. Once the profile has been deleted, go to the available wireless networks and choose to connect to your network.
5. It will ask you for the network key. Please enter that. A new network profile will be created and you should be connected.

Keep me posted. Please reply for any further questions.

Hello. Thank you for your answer. The problem remains unsolved, though. First, here i dont have access to the modem. A cable was pulled to the appartment and a wifi router was plugged to it. I rebooted the rooter but no effect. Second, i deleted the profile as suggested. Thereafter, the home network does not appear in the list of available networks. So impossible to create a new profile. I created a profile corresponding to the home network, set it up to connect whenever network is available. And still nothing. Any idea?

Hi Jerome,

Thank you for the reply. Make sure the router is set to broadcast the SSID (refer to the manuals of the router). Also, I will recommend you to uninstall and re-install the wireless driver:

1. Click on ‘Start’ and right click on ‘My Computer’ and click on ‘Manage’.
2. Click on ‘Device Manager’.
3. Click the + sign to expand the ‘Network Adapters’ entry.
4. Right click the wireless adapter and click 'uninstall'.
5. Once done, click on 'Start' and click on 'Control Panel'.
6. Click on 'Programs and features'.
7. Look for wireless card's software; right click on it and click on 'uninstall'.
8. Restart the system and click on the link: http://dell.to/QjjZDA 
9. Enter your system's Service tag and select the operating system.
10. Go to 'Network' and click on the appropriate wireless driver for your system.
11. Click on 'Download File' and select 'Single-file download'.
12. Click on 'Continue'.
13. Click on 'Save' and save the driver on the desktop.
14. Right click on the driver from the desktop and click on 'Run as administrator'.
15. Follow the on screen instructions to install the driver.
16. Restart the system.

Please share the model number of the router in case the issue is not resolved.

He has to be able to access the modem to do anything. This is not a correct wireless setup. A router cannot be attached to a cable from another location. Who knows what it is attached to? Try just attaching the cable (ethernet?) directly to the network card in the computer and skip the router. It will not be wifi and definitely not secure but it might work.

Hey. Problem seems solved. I unplugged cable from router and plugged in laptop directly. Strangely, i got no connection. I turned off router and laptop. Put cable back in router, and my laptop detected home network again.

Mary g, my guess is the internet company has a central modem for the building, and they pull cables to peoples appartments.

Vikram, ty forassistance. Ill keep your post in case such an issue occurs again.

Cheers
