I would not do this for a production environment, but for a lab, why not?

aironet native vlan vs vlan , band steering
http://itknowledgeexchange.techtarget.com/network-technologies/configuring-multiple-ssids-in-cisco-1250-access-points-series-3/
http://www.netadmin.com.tw/article_content.aspx?sn=1201100001
IEEE 802.1Q協定在VLAN中通常用來連接多個Switch與Router設備,而Cisco的設備在Fast Ethernet和Gigabit Ethernet介面上都支援IEEE 802.1Q協定。基本上,每一個套用802.1Q協定的埠都會被指定成Trunk類型,而所有在Trunk上的埠都隸屬於Native VLAN,雖然預設如此,但管理者還是可以指定到不同的VLAN內。
Native VLAN是設備上預設的VLAN,一開始拿到Cisco Switch設備時,所有的埠都會被指派到Native VLAN中,因此所有的埠都可以互相通訊,因為都屬於同一個VLAN。
而Native VLAN有一個作用是,所有沒有被貼上標籤的資料都會被送往這個Native VLAN。每個VLAN都會有一個ID,用來區分各個VLAN,而Native VLAN的預設ID就是VLAN 1。
還有一點值得注意,只有802.1Q協定才有Native VLAN,ISL並沒有Native VLAN。也因為沒有貼上標籤的資料都會在Native VLAN上遊走,所以Switch設備就不會在Native VLAN上傳遞的資料貼標籤了。
接著來看下面這個範例,就可以參透Native VLAN的所有觀念。假設現在架設三個VLAN,其VLAN ID分別是VLAN 1、VLAN 2及VLAN 3。其中,VLAN 1是Native VLAN,之間用兩台Cisco Switch設備連接著,而在Cisco Switch中間有一台Hub,如下圖所示。
其中,IP為10.1.*.*是處於VLAN 1中,而IP為10.2.*.*處於VLAN 2中,IP為10.3.*.*則被分派於VLAN 3之中。
因為10.1.1.1和10.1.1.3都屬於Native VLAN,所以由10.1.1.1和10.1.1.3互相傳遞的資料都不會被貼上標籤,因此這樣的資料也可以被10.1.1.2收到。

c3550-i5q3l2-mz.121-20.EA2 is the directory that the IOS file is in
This gives you the IOS file name in the directory

.net framework 3.5 offline installer xp
If you are using a localized version of Windows the setup automatically tries to download the language pack for your location.
To bypass the automatic download you can specify English as the installation language by using the following command line:
C:\path\to\installer\dotnetfx35.exe /lang:ENU
After the setup is complete you can download and install the language pack for your location manually.
Links:
- Microsoft .NET Framework 3.5 Service Pack 1 (Full Package) (contains English language only)
- Microsoft .NET Framework 3.5 SP1 Language Pack (use the "Change Language" dropdown on the page to select your language)

Give your computer the 10.0.0.1 (subnet 255.255.255.0) ip address. make sure it is on the same network as the access point.
start i.e. tftp_32 and point it to the directory which contains the image file.
on the console type:
set IP_ADDR 10.0.0.2
set NETMASK 255.255.255.0
DEFAULT_ROUTER 10.0.0.1
