I have a new belkin n150 when i conect to the modem, there is a amber flash light for the modem on the router, when i conect the computer directly i have conection, i have folowed all the instructions but no success on it

Hi Christopher s crisp,
Is it blinking Orange or steady?
Blinking amber: The Router can't detect the modem. Either the
modem is off, is not plugged into the Router, or is unresponsive.
It could be the modem.
You can try connecting the modem directly to computer bypassing the router and see if that works.
Check the LED on Modem.
Do you have other computers to test the connection?
Might need to talk to ISP if issue with Modem.

Let me know.
Thanks

Disconnect the ISP modem power and network / cable. Do the same with the router. Wait a few minutes and reconnect starting with modem.

Try just unplugging the router for 20 seconds then plug it back in.

Your Router Should Be Configured for your Internet Service Provider. To do that you have to contact your Belkin technical support & they will give you a hand. Or Please update some Details about your Internet connection who is your Internet Service Provider. What type of Internet Connection are you using is it DSL or Cable. And i will walk through the Steps For you... :)

If the wireles light is flashing Amber .. Some one outside your house is trying to access the Wireless network . If it is always flashing amber.. try with a Firmware update available in belkin.com/au/support.

Thank You

As i understand you have a router provided by your ISP: MTNL, you need to configure the Belkin router in Dynamic mode and not in PPPoE. Then restart the devices by unplugging the power from MTNL router and Belkin. Wait for 20 secs, then power up MTNL router 1st, wait for all lights to get steady and finally power up the Belkin wireless router. Then you will find the modem and internet light lit up properly.
For any further clarifications, revert!

Thanks and regards,
Arvind

Change the connection type into Dynamic

Do you have a user name and password to connect to the internet?
If you have that then you will need to set the router to PPPOE connection.
If not , then you will need to set the router to DHCP mode.
First make sure that your computer will be able to go online through the modem. It is very simple and you don't need the CD.
You can set up the router like the DSL connection.
