The Wireless tab contains wireless communication options. The Wireless Basic Settings page offers parameters any wireless network begins to be set up with.
First of all, you can disable the wireless interface altogether, assign the SSID and enable/disable its broadcasting. You can also manage communication channels here. If you select a channel width of 20MHz, there will be no special features which only appear when you select a 40MHz wide channel. If you do, then besides the 40MHz channel you will also have to choose one 20MHz channel for initializing communication and for operation of 802.11b/g equipment.
On the Wireless Security page you can choose the method of encrypting wireless connections and the encryption algorithm.
To filter access to the router via the wireless network, you should go into the Wireless MAC filter page.
This filtering works by allowing/prohibiting devices whose MAC addresses is on the appropriate list to access the router. The list contains up to 50 addresses.
Few users will tamper with the options of the Advanced Wireless Settings page.
These are fine wireless network settings. For example, you can unite all wireless devices connected to the router into an isolated virtual network. You can also specify such parameters as speed of different connections, sync packet transfer frequency, maximum packet size within packet aggregates, etc.
