This is the procedure NCF uses to configure Thomson/SpeedTouch 516 and 585 modems out of the box or after a factory reset. The process for older model SpeedTouch modems is similar. To learn more about configuring your particular modem, consult the manual for your modem.
Connect the modem to power and reset it to the original factory configuration by holding the reset button for 15 seconds…
After a factory reset,

The WPA-PSK wireless key code is printed on the label on the bottom of the modem (also on a sticker on the Set-up CD included with the modem).
NOTE: Since in the past the default Thompson wireless keys have been easy to hack it is recommended that you change the wireless key.
NCF recommends making wifi changes on your modem from a computer that is connected via an ethernet cable to one of the LAN ports behind the SpeedTouch.
1. Open web browser and type http://192.168.1.254 or http://dsldevice.lan in to the address bar. Press Enter.
2. Enter the username Administrator and the DSL password.
3. From the Home Page, select the link Wireless towards the bottom of the page.

4. From the Wireless Access Point page, click on the Configure link at the top right corner.

5. From the Security section of Wireless Access Point configuration page, make the following changes:

6. After this change is applied, you will have to enter the new password on your client devices (computers and mobile devices) to reconnect over wifi.
If you have a ST516 DSL modem connected to a router, it is best if the router’s idle timeout feature (if it has one) be disabled. Otherwise your DSL connection may go up and down every five minutes.
To see if you have the problem, log into the NCF StartPage and then click on the link Your recent DSL use. Scroll down to ‘Connection details’. If there are many session of short duration (eg., 5 minutes), you probably have a router with an idle timer running.
To fix this there is a router setting usually called something like “Maximum Idle Time” which will cause the internet DSL connection to be dropped after a period of no internet use. As long as you are using the internet, this setting does nothing, but when you stop using the internet, after the period specified by this setting, your router will tell your DSL modem to disconnect and reconnect. This usually acceptable, but pointless, although it often causes grief for members. It is best to disable it. Change the number to something larger than 3 days (eg., set it to 5000), or, on some routers, you can disable it altogether (try entering 0).
So if you are getting regular DSL cuts, check that your router idle time is set to a large number of minutes (eg., 5000). Some routers may have an “always connected” setting which will override all of the foregoing and leave your DSL connection in permanent connect mode, which is the ideal solution!
You can check that it worked by waiting a day for the DSL use page to be updated (it is updated nightly).
