Use the wireless network card of your laptop in Windows 7 to define a hot zone for your mobile phone to access the Internet.

Windows 7 allows you to define a laptop (or a desktop with a wireless network card) as a hot zone for WiFi devices around to share the network, so as to establish a point-to-point connection to a wireless LAN, this is a new feature in Windows 7 and is very convenient to use. It solves the problem that wireless networks can be shared without a wireless router.

In the Windows 7 taskbar, click the network connection icon and select "Open Network and sharing center", for example:

Click "set new connection or network". If your machine has a wireless network card, Windows will display "set wireless temporary (computer to computer)" in the "set connection or network" window) network option, such:

Make sure that the current Windows account has the permission to set up the wireless temporary network, and the machine is not added to any domain or non-Domain Controller, but is only a member of a Working Group. Otherwise, a temporary network cannot be created. Click next and the "set temporary network description" page appears. Click Next to configure the temporary wireless network.

Enter the name of the wireless temporary network so that nearby WiFi devices can find the hot zone. Select the Security type and set the Security Key (for temporary use only, you can set a non-identity authentication method. In this case, no password is required for remote device connection ), after setting, you will see an additional wireless connection icon at the network connection icon in the Windows taskbar. Select it and click Connect!

In order to allow the created hot zone to connect to the Internet, you also need to set up network sharing for the local connection on the notebook, find the network adapter for the local wired connection on the notebook, and click Properties, in the displayed dialog box, select the "share" tab and select "allow other network users to connect to the computer over the Internet (n )", select the network connection you want to share from the drop-down list. This should be the connection corresponding to your wireless network adapter. Click "OK". Windows will prompt that the IP address of the network adapter you want to share will be reset. The default configuration is enough. Here, the IP address of the wired network is automatically obtained during the test, and the IP address of the wireless adapter to be shared is automatically set by windows, if your wired network IP address is automatically specified, you may need to manually re-specify the IP address of the wireless adapter, but generally we do not need to manually modify it.

If you have a Wi-Fi device nearby, you can try the connection now. I can use my wife's Nokia e71 to immediately search for the hot zone and connect to it. Because my own G1 is a 1.6 Rom Android system, you need to make some settings to find this hot zone. There was a post on the android Forum saying that the Android system itself does not support hot zone connection and the system configuration information needs to be modified. Here is a post that details how to make the G1 mobile phone connect to the notebook's ad-hoc through WiFi point-to-point, if you are interested in your Android mobile phone, you may wish to see that, after all, WiFi can be connected, making it much easier for your smartphone to access the Internet.

If you cannot find or connect to a Wi-Fi hotspot on your mobile phone, try restarting your mobile phone or the WiFi function.

In addition, many laptops now support hot plugging of wireless NICs, and there are shortcut keys on the notebook Operation Panel to remove or enable wireless NICs, before setting a wireless temporary network, make sure that the wireless network card is enabled. Windows 7 also has a shortcut key to view the current status of the wireless network card, Windows key + x key, such as the content displayed in the Windows Mobile center window on my machine, in this window, you can directly open or close the wireless network.

Finally, we would like to remind you to set a safer password for your hot zone. After all, wireless networks are different from wired networks, always watch out for your neighbors quietly connecting to your wireless network and intruding into your computer! I would also like to thank the post written by William amblade on the android Forum. Without his mention, even if I created a wireless temporary network on Windows 7, I could not connect my G1 to wifi. In addition, you must be reminded that users interested in the Android system must have a certain understanding of Linux. Otherwise, you will see the top players in the Forum talking with each other, but you will see the cloud, haha! In a word, as a programmer, you must constantly learn and update your knowledge...
