Configure “Always On” mode (ADSL routers)

Introduction

The most likely cause of the internet light going red, or off, on an ADSL router, is that “Always On”is not configured on the router. This is not part of the router's default configuration.

Symptom

If you are not using the internet for 30 minutes (1800 seconds) or more, you may see the internet light go red, or off (depending on make/model of router).

This can give the appearance that the internet has dropped, or disconnected. What has actually happened is that the virtual path from the exchange equipment (DSLAM) to the internet has disconnected. Opening a web browser, and typing in a web page, will usually “wake up” the router, but if using wireless devices, this can sometimes cause the wireless connection to time out and disconnect.

You can set your router to “Always on” to solve this, or in some older routers this may be referred to as a “nailed up connection”.

Router login

To do this work, you will need to log in to your router. To do this browse to your router at:-

http://192.168.1.1

At the prompt:-

Enter your admin username & password. Unless you have changed this, the default is normally:-

Username : adminpassword : admin

The following pages cover details on how to enable this for the following series of routers:-

• Huawei & some D-Link DSL 3780, but not HG635 super router

• D-Link DSL (but not the DSL-3780)

• D-Link DSL-3780

• HG633 & HG635 routers

• Netgear

D-Link DSL (but not the DSL 3780) routers

Login to the router & go into “Advanced” mode.

Click on the “Setup” tab at the top & “ADSL Setup” down the left hand side.

In the “PPOE/PPOA Internet Connection Type” section, change the “Idle Time Out” option from probably “30” minutes to “0” minutes.

Note: if the idle timeout feature you mentioned doesn't allow a '0' anymore Enter the maximum amount of "31536000 " which is the equivalent of 356 days

Then click the “Save Settings” button at the bottom of the page.

See the next page about doing this on the 3780, it is slightly different.

Configure “Always On” mode (ADSL routers)

D-Link DSL-3780

Login to the router first, then go to the Setup tab across the top & Internet Setup down the left.

This is slightly different to the other DSL routers, as it has both “Connect Mode Select” & Maximum Idle Time options. However, setting the “Connect Mode Select” to “Always-on” greys out the Maximum Idle Time setting.

Then click the “Add/Apply” button at the bottom of the page.

HG633 & HG635 routers

Note: this option is only available if these routers are connected to an ADSL line, it is not a valid option when the router is directly connected to a VDSL line. VDSL uses the WAN connection modeof PPPoE, so it is by definition, always on. Like any other Ethernet connection, doesn't have or needa trigger mode, if the router is powered on it will connect.

Log on to the router, click on the “Internet” tab across the top & then “Internet Connection” down the left hand side. Then click on the link “Click here to show ADSL Connection”.

In the next screen, expand either the “Internet_DSL” section, or the “PTM” section (depends on the current configuration of the router) & click the “Edit” button:-

Scroll down to the “PPP Information” section and the “PPP Trigger mode” is probably set to “Dial on demand. Change this to “Always online”. Note that the “Idle time” & “Set idle time manually” options will no longer be available.

Click the “Save” button.
