Hi, my name is Avril Salter and welcome to this short complimentary video. What we are going to take a look at today is how to configure your 802.11 Wireless LAN settings on your client devices.
Here I have a laptop running Windows 7 and so we are going to start by selecting the Start menu and selecting the Control Panel. Then we go into Network and Sharing Center, and then we are going to change our adaptive settings. Here you can see my Wireless LAN card and you can see the manufacturer is Intel and that it supports an A, a G, and an N radio. Even though the manufacturer is Intel and there are some differences between different vendor Wireless LAN products, you will see that many of the settings are the same. By looking at this video you should be able to configure different 802.11n devices.
I am going to right click this and select Properties and then Configure and then the Advanced tab. Now you can see the settings that I am able to change on my 802.11n radio. The first thing I want to do is change the channel bandwidth here of operations in my 2.4 GHz band and I want to set it to Auto. What that is going to enable me to do is, if I am able to connect to an access point that is supporting a 40 MHz channel, then I will be able to take advantage of that and get up to a higher data rates. Because it is set to Auto, if the access point is unable to support a 40 MHz and is only using a 20 MHz channel then I will also automatically use a 20 MHz channel.
I want to do the same for operations in the 5GHz band as well, selecting auto so if 40 MHz is available I can use it. Then in my 802.11n mode, I want to make sure this is enabled because this is the setting that allows me to use my mode. My multiple input multiple output (MIMO) antennas. That is very critical for me to get up to the high data rate and also to extend the range of my cell as well. I have selected and made sure that my 802.11n mode is enabled.
Now the Fat Channel Intolerant indicator is a very important one to make sure that you set to being disabled. This is part of the specifications of 802.11 that said devices can notify an access point, “Hey I am intolerant of operating in a 40 MHz channel” When the access point gets that notification it has to revert back to a 20 MHz operation. If you want your access points to take advantage of operating in a 40 MHz band you need to make sure your clients have this feature disabled. It should be disabled by default.
That concludes our settings, the main ones that relate to Wireless N are setting the channel bandwidth you again want to set to auto, the 802.11 mode to allow your antennas to work, the Fat Channel Intolerant indicator, very important one, and the others really indicative of how a radio operates and not specific to N.
I hope you found this sort video to be useful and thank you for listening.
