wireless router = Asus wireless (AAM6030Vi-B1 ADSL modem)

the scenario is this. I am plugging this router direct to the phone jack-point,using the same filter and cable i am using for connection the standard router which is cisco 827H.
Scenario 1
wall jack-point==>filter==>rj11==>wireless router....i dont get adsl signal on the router.

Went and borrow another wireless router today a D-link wireless router getting the same results (no sync).

Scenario 2
wall jack-point==>filter==>rj11==>standard cisco router ... i do get get adsl signal on the router

out off curiosity borrowed another standard D-link router i am able to get Adsl signal.

Before we talk Ip i should have layer 1 Up.(is that right?).

I just purchased this gear on my own.

I am plug one router at a time , i am not using this routers at the same time.

So what worries is that two different wireless routers i dont get adsl signal.
Any standard router I do get signal

respect
