-This tutorial describes creating separate Wireless LANs. The example given here is creating two separate WLANs, one for secure network traffic with access to the Internet, the other for insecure Tivo traffic with no access to the "secure" network or the Internet. Additionally, one physical port (4) is associated with the insecure WLAN. This tutorial requires v.24. DD-WRT v.24 RC-5 was used in making this tutorial. 
-The purpose for this configuration is that I have two (DirectTV) Tivos, one with a wireless connection that doesn't support encryption and the other with a wired connection. I wanted to allow these two devices to communicate, without compromising the security of my internal network (since my wireless Tivo doesn't support encryption). 
-== Configuration == 
-=== Step 1: Create Wireless Networks === 
-a) Go to the 'Wireless -> Basic Settings' Page. 
-b) Create the secure network on the physical interface (wl0) and the insecure network on a virtual interface (wl0.1).  
-An example configuration is as follows: 
-Physical Interface wl0 
-Wireless Mode: AP 
-Wireless Network Mode: Mixed (or whatever you want) 
-Wireless Network Name (SSID): Home Network 
-Wireless Channel: Auto (or whatever you want) 
-Wireless SSID Broadcast: Enable 
-Network Configuration: Bridged 
-Virtual Interfaces wl0.1 
-Wireless Network Name (SSID): Tivo Network 
-Wireless SSID Broadcast: Disable 
-AP Isolation: Enabled 
-Network Configuration: Unbridged 
-IP Address: 
-Subnet Mask: 
-c) Go to the 'Wireless -> Wireless Security' Page. 
-d) Configure wireless security settings any way you want (I used WPA for my Secure Network and no security for my Tivos). 
-Physical Interface wl0 
-Security Mode: WPA Personal 
-WPA Algorithms: TKIP 
-WPA Shared Key: ********* 
-Key Renewal Interval: 3600 
-Virtual Interfaces wl0.1 
-Security Mode: Disabled 
-=== Step 2: Create Tivo VLAN (2), bridge (br1), and associate appropriate the appropriate interfaces (port 4 and wl0.1) === 
-a) Go to the 'Setup -> VLANs' page. 
-b) Change port 4 to VLAN 2 
-c) In addition to the above (I'm not sure that a & b actually do anything), configure NVRAM to move port 4 to VLAN 2 with the following commands (either through telnet/ssh or 'Administration -> Diagnostics') 
-nvram set vlan0ports="1 2 3 5*" 
-nvram set vlan2ports="4 5t" 
-nvram commit 
-d) Create the following startup script (through 'Administration -> Diagnostics') 
-brctl addbr br1 
-brctl addif br1 wl0.1 
-brctl addif br1 vlan2  
-ifconfig vlan2 up 
-ifconfig br1 up 
-=== Step 3: Internet Access or DHCP Server on Tivo Network === 
-Now that the basic network has been created, some additional things might come in handy (such as Internet access or a DHCP server). This section could be used to document this by another user who has need for these features. The references section provides links to several different tutorials that all provide information that will help in configuring these types of things. Although I would start with [[VLAN Detached Networks (Separate Networks With Internet)]]
