Thread: Two Wifi Routers in Cascade?

I have a BSNL Wifi ADSL Modem+Router , unfortunately the coverage area of WiFi is not as good as expected and the signals are lost even in the same house premises. I have another WiFi Router (LinkSys Wireless B BEFW1154v4) that provides WiFi connectivity to a greater distance (but it doesn't have ADSL modem).

Now my question is Can I use the two in a cascade.. Connect LinkSys router at a distance on Wireless from BSNL and Serve WiFi Clients (Laptop and Cell Phone) from LinkSys router and connect to internet.. How can I connect the two routers on Wireless? The LinkSys router does have a port for "Internet" but that is an ethernet port.. so it can work thru a wired connectivity between two.. but is it possible to connect the two on wireless.. also any specific consideration (gateway/dhcp) to take care in such a scenario ?

thanks in advance!

Not possible to link BSNL ( 3-in1) adslmodem/lanport/Wifi router and Linksys wifi router in wireless mode.
( mention bsnl Modem router make/model/number )

so it can work thru a wired connectivity between two..

Connect Rj45 from BSNL unit to linksys wifi router.
You can keep both units at same place or use
RJ45 cable ( max 100 meters theoretically .)
Dhcp enabled in modem.
