Wireless Security System Broadband Technology in Different Environments
The world of Internet users is growing daily. Millions of people are more interested in this type of technology. People like the wireless networks at home, but that isn’t the only place that the security of wireless system broadband networks come into question. The workforce is using these systems. Mobile employees that are on the road a lot will use this type of technology. There are also consumers and all types of environments where wireless networks are used:
Block users from connecting to Wi-Fi networks
The network shell (Netsh) command line utility allows local or remote configuration of network devices such as wireless interfaces. Using the Netsh wlan option you can create filters that block users from connecting to specific wireless networks which may pose a risk to the security of your environment. Users connecting to unsecure open wireless networks increase the risks of their computers being compromised.

How to Modify the Default IP Address of a Wireless Hosted Network
The default IP address of Windows 7 (and Windows Server 2008 R2) virtual Wi-Fi Access Point (AP) feature called Wireless Hosted Network is 192.168.137.1. Although, this address is highly unlikely to conflict with other addresses that you may have configured on your network still, you may wish to change it to another value. In order to be able to change this default IP address you need to modify a Registry setting as follows:

Disabling Network Bridging in Windows 7
If an organization has stringent security policies in place that control network traffic and LAN connections, and does not control the users’ ability to bridge the organizational internal network to an insecure wireless network then the organization may fail its objectives to secure its internal assets appropriately. Laptop users connected to the wired LAN can also connect to a neighbouring insecure wireless network and create a bridge between the networks’ segments which allow the laptop users to expose internal resources to external third-parties.

A quick Peer-to-Peer Wireless Network
Imagine you need to share some files with a friend or with a colleague while in a meeting and do not have any network means to connect to! You can set up a temporary wireless network between two or more computers running Windows 7 or Vista assuming that both computers are equipped with a wireless interface and are within 9 meters of each other. An ad hoc wireless network is quickly set up as you can see from the following steps:

Connecting Wireless Computers
Connecting a wireless-enabled computer running Windows 7 to a wireless network is pretty straight forward however; if that doesn’t work you can try the netsh command line tool. Below, you will find the steps required to connect your computer to a wireless network using the netsh wlan command. Alternatively to netsh, you can either open Network and Sharing Center and click Connect to a network or click the network icon on your taskbar at the bottom right section of your screen.

Wireless Network Problems
In general, troubleshooting network connectivity issues require the same techniques but with Wireless Networks there is an additional layer that you need to consider. You need to be aware of the wireless layer and the implications it has over your connection. In this article I will point out the most common wireless problems and how to resolve them.
