If there is only one network cable in the house, but two or more laptops need to connect to the network, with the help of software, you can turn the notebook into a wireless router, that is, "WiFi Hotspot ".Taking Windows 7 as an example, it actually comes with WiFi and softap (Virtual Wireless AP) functions. You only need to activate them to turn your notebook into a "WiFi Hotspot ", connect other laptops
The following content is found in Sun's White Paper 1-. Due to my understanding, it is not a translation article (poor English, poor translation ). here, I only focus on the recycling abstraction mechanism, which is not involved in reference counting and specific algorithms.
Hotspot (j2se 5.0, also applies to 6.0 according to the White Paper) uses the so-called generational collection mechanism, which divides objects into young and old (and permanen

But recently, Win7 system users reflect that the "laptop wireless network can not find a connection Wi-Fi hotspot" error, resulting in network. So how do we solve it? Let's take a look at the Win7. Notebook wireless Networks cannot find a workaround for connecting to a WiFi hotspot.
Unable to start the hosting network when creating a WiFi hotspot because we've created it before, and then we deactivate it and then it's turned on, and the solution we can do is to remove the recreate.
