Why se567 ADSL wlan light goes off - D-Link ADSL2/2+ Modem/Wireless Router 4-Port Switch, 802.11g, QoS (DSL-2640B)

The phone line does two jobs. Voice phone which is what it was originally used for and ADSL modem which works at a high audio frequency.
Somewhere between the phone socket and the modem should be a filter splitter. One part goes to the phone and the other to the router. Make sure you have that.
The modem will have a power light and several additional lights. Assuming the power light is on we are interested in two of them; The ADSL light and the Internet light. When you switch the modem on you should first see the power light flash then go solid. Then the ADSL light will flash and then this should go solid. If this light does not come on then you have not plugged the phone wire in properly. If this light just keeps flashing slowly then the modem can't see an ADSL signal on the phone line. If you have a spare router you could try it and see if the ADSL light goes solid on that.
If the ADSL light is fine then the modem has locked onto the signal on the phone line, sync'ed. If not then this is the problem you must solve. Ask your ISP if service is set on your line.
The next light is the Internet light, this maybe a symbol like an i or a world. This light will begin flashing then go solid. It will flash with Internet traffic. This means you have Internet, as far as the modem is concerned. If this light does not stay on then your ADSL account name and password maybe wrong. You can correct this but that's a different question you need to ask.

Try to pull the wires and restart your modem if there are no changes you should ask fof techy assistance

Try placing your laptop as close to the location of their router, removing barriers like walls for best speeds. Maybe your neighbour is having the same problem. Have them unplug the router for 10 sec (no more). Power-cycling once-a-month or so, is a good thing

Hello there!

Only thing that can cause your wlan light not working consistantly or with some blinks (which is normal thing) is bad lan cable which leads from your ADSL modem to your wlan entrance on your wireless router, please check that cable in order to fix that problem. Cable doesnt need to be coaxial so it can have 2 different lan sets (2 poles of exits male and female exit). Thats it ! =)

Please rate solution! =)

Reset your router .
Press reset button for 15 seconds then all settings are reset to factory defaults.
Then check let me know.

login to the router using the ip address 192.168.1.254 default password is telus

you shoul also have a wireless icon on the x6. if someone is using your wirless link and you are not. the wireless icon should be flashing.
if you don't have the wirelss icon, then you have to have software to monitor the modem activity.
