Scope
This article gives directions for installing DSL service with DD-WRT, applicable also when changing over to DSL from cable. .
Background
DSL providers typically configure the modem in ways that are easiest for them and not optimal for the end user. These setups preclude some of DD-WRT's desirable features resulting in diminished performance and security. The best configuration is as with cable: modem in bridge mode and all routing/security performed by the router.
Step-by-Step Instructions
- Obtain your network name and password.
- Network name is often the same as account name, but network password is nearly always different from account password.
- Is most easily grabbed when the account is first set up.
- Is not generally retrievable from the modem's GUI.
- You 'own' this information. Don't let the service provider charge for it.
- This is a must-have. Can not proceed without it.
- Wire directly from DSL modem to PC and test for good connection.
- If a laptop, disable wireless.
- If resurrecting an old modem, repairing a previous disaster, etc., hard reset the modem by holding down the Reset button until red/orange LED flashes. (Hard reset is otherwise not necessary.)
- Verify connection by surfing to one or more websites.
- If no web access, work with service provider to establish an Internet connection.
- Access modem's GUI, set configuration
- Point browser to same address as used for initial setup. (ATT modems use 192.168.1.254)
- Here, three items need to be changed. A detailed example is given for a typical ATT modem in the next step; adapt to your hardware:
- Change device IP and subnet mask to non-conflicting address 192.168.100.1, subnet mask 255.255.0.0
- Turn Off DHCP service
- Set BRIDGE mode
- The following is for a Westell model E90-610030-06 (FW 03.08.02). The above three changes are implemented:
- Pick 'Home Network' then 'DHCP', change 'Device IP Address' line to 192.168.100.1, change Subnet Mask to 255.255.0.0, then uncheck 'LAN DHCP Server Enable' box and hit 'Save Changes'.
- While the device self-reboots, change the connection on PC to be compatible with the new settings: IP 192.168.100.2, Subnet Mask 255.255.0.0, Default Gateway 192.168.100.1 (In winXP, these three items can be found under network properties, 'Internet Protocol (TCP/IP) Properties', click 'Use the following IP address' and enter the numbers.)
- After connection re-establishes with new settings (may take a minute), log back on router at 192.168.100.1, pick 'Broadband DSL Line' and select 'Configure Connection'. On the 'Protocol' line pick 'Bridge Ethernet' (screen should change to show the line: 'Bridge Type: Bridge' ), then 'Save and Restart Connection'.
- Note modem's GUI is no longer accessible, but there is no further need for this. To regain GUI access for any reason, simply hold down Reset button until red/orange LED flashes. (Modified settings will be lost.)
- Cleanup and prepare router for DSL connection
- Unplug modem's power cord, then Ethernet cable
- Return PC's TCP/IP settings to normal (usually 'Automatic')
- Connect loose Ethernet cable end (from PC) to DD-WRT router (any of the LAN ports) and browse to GUI (usually at 192.168.1.1)
- On Setup tab, on Basic Setup page, change Connection Type to PPPoE and key in User Name and Password ('network password' from step 1.), and Save. Power down router.
- Wire for normal operation and Go!
- Connect modem to router's WAN port by Ethernet cable
- Plug in modem and allow to sync (DSL light stops blinking)
- Plug in router
- Done. Happy DSL!
