- | Goal of this tutorial is to help you to extend your wireless network using WDS. | + | This page is now deprecated, instead see: [[WDS_Linked_router_network|WDS Linked router network]] |
- | There are many howtos on this manner. This is one of the way to repeat your signal. | + | |
- | It will work as a true layer2 bridge repaetater, meaning all clients can see each other and can share data. | + | |
- | Client bridge (Routed) repeater is just a workaround as Mr BransLayer (main developer of dd-wrt) stated. | + | |
- | Advantages of WDS is that clients can move seamlessly from one AP to another. | + | |
- | | + | |
- | | + | |
- | | + | |

- | | + | |
- | '''Note:''' WDS and Client bridge both share a common downfall, that is, for every hop, | + | |
- | the effective bandwidth is reduced by half. It is normal because WDS AP and WDS STA are working like a wlakie-talkie. | + | |
- | Only one can "speak at the time" and the other will have to listen. | + | |
- | WDS STA has to connect to the main AP, WDS AP, via wireless and therefore the radio can not receive or send information to the client | + | |
- | (laptop, cellphone, etc) when it is being sent or received to the main AP. | + | |
- | You can connect as many routers as you like (at least in theory) like this: | + | |
- | WDS AP (root) < -- > WDS STA + WDS AP < -- > WDS STA + WDS AP < -- > WDS STA + WDS AP... | + | |
- | This is called '''Multi WDS Repeater'''. | + | |
- | | + | |
- | You can configure 2 different SSIDs in the WDS Repeater. | + | |
- | The networks can have the same SSID and the same security settings. | + | |
- | Doing so will allow your wireless clients to choose which device to connect based on signal strenght. | + | |
- | This tutorial is slightly different. Every WDS AP will have different SSID. This is suitably for hotels | + | |
- | where every floor will have its own SSID (e.g 1st, 2nd, 3rd etc). | + | |
- | | + | |
- | '''Prerequisites:''' | + | |
- | Two Qualcomm Atheros (QCA) chipbased routers. | + | |
- | Both of them must use same 802.11 standard (i.e. 802.11n/802.11n) | + | |
- | Both routers will be in the same subnet 192.168.2.0/24 in my example. First (root) will host internet and will have local IP 192.168.2.5 | + | |
- | and the second will have local IP 192.168.2.25 | + | |
- | You can change this values according to your needs. | + | |
- | Set DHCP on first router: | + | |
- | | + | |
- | Access Point (root router) | + | |
- | AP Basic Wireless config: | + | |
- | | + | |
- | In Wireless->Basic Settings: | + | |
- | | + | |
- | 1. Set '''Wireless Mode''' to "WDS AP". | + | |
- | | + | |
- | 2. Change the '''SSID''' to something known, and note it. | + | |
- | | + | |
- | 3. A '''fixed Channel''' is also recommended, but not required. | + | |
- | | + | |
- | Click '''Apply Settings'''. | + | |
- | | + | |
- | In Wireless->Wireless Security: | + | |
- | | + | |
- | 1. Set the security to whatever you like. | + | |
- | | + | |
- | 2. Note the security type and passphrase. | + | |
- | | + | |
- | Click '''Apply Settings'''. | + | |
- | | + | |
- | '''WDS Station'''(second router) | + | |
- | | + | |
- | WDS Station Basic Wireless config: | + | |
- | | + | |
- | This is the harder part. | + | |
- | | + | |
- | Connect the computer to the WDS Station, and set a static on the computer to 192.168.2.254. | + | |
- | Log into the WDS Station's interface. | + | |
- | In Setup->Basic Settings: | + | |
- | Under WAN '''Connection Type''', set Connection Type to "Disabled". | + | |
- | Enable STP | + | |
- | Under Network Setup, Router IP: | + | |
- | Change the '''Local IP Address''' to 192.168.2.25 (or something out of range root router DHCP server). | + | |
- | Change the '''Gateway''' to 192.168.2.5. | + | |
- | Under Network Setup, Network Address Server Settings (DHCP), change DHCP Server to '''Disable'''. | + | |
- | | + | |
- | Click '''Apply Settings'''. | + | |
- | | + | |
- | | + | |
- | In Advanced Routing->'''Operating Mode''': | + | |
- | | + | |
- | 1. Set the Operating Mode to '''Router''' (this will disable NAT). | + | |
- | | + | |
- | 2. Under Dynamic Routing choose '''LAN&WLAN''' Interface. | + | |
- | | + | |
- | Click '''Apply Settings'''. | + | |
- | | + | |
- | Log in to the new IP address you set for '''Local IP Address'''. | + | |
- | Under Wireless->Basic Settings (read carefully): | + | |
- | Under Physical Interface ath0: | + | |
- | Set '''Wireless Mode''' to "WDS Station". | + | |
- | Set '''Wireless Network Name''' to the SSID used on the AP (this is the SSID that the WDS Station is connecting to as a client). | + | |
- | Under Virtual Interfaces, click '''Add'''. | + | |
- | Under Virtual Interfaces, Virtual Interfaces ath0.1 (this is the interface that client computers can connect to): | + | |
- | Set the Wireless Mode to "AP" (or "WDS AP" if you want Multi WDS). | + | |
- | Set the SSID to something '''DIFFERENT''' than the previous SSID -- '''IMPORTANT'''. | + | |
- | Click '''Apply Settings'''. | + | |
- | Under Wireless->Wireless Security: | + | |
- | Under Physical Interface ath0, set security settings to match those on the AP. | + | |
- | Under Virtual Interfaces ath0.1, set security settings. The security settings here may be different than previous, but most likely you'll want to set them the same. | + | |
- | Click '''Apply Settings'''. | + | |
- | | + | |
- | Additionally you can '''disable SPI Firewall''' because it is not needed. | + | |
