Two wireless modems on a single connection?

Alright, given your house size a single wifi router should be enough. What is your budget ? and in which room does the phone line originate ?

Alright, given your house size a single wifi router should be enough. What is your budget ? and in which room does the phone line originate ?

I ALREADY have: ZyXEL P-660HW-T1 - 802.11g Wireless ADSL2+ 4-port Gateway over POTS
I am planning to get: A D-Link wireless router with extra antenna to increase coverage. Budget is not any issue. Getting connectivity in ALL rooms is important.

The phone line originates in the Hall. So far with the existing modem (ZyXEL P-660HW-T1), the wifi signal is barely available in the bedroom. There is NO SIGNAL in the study.

This is the reason, I am attempting to activate a Wifi router in whichever room I would be at any point.

Any advise on how the connection should be?

So far the Wifi router ONLY works in the Hall. There is no connection when I connect to the phone line in the bedroom or the study.

Thanks a lot for helping.
