netgear has it i think(since exact model no. is not mentioned) but i doubt binatone has it as it is a cheap bsnl issued wireless adsl modem.also post the full model name of netgear as N150 is simply a classification(N150 for 150mbps wax wifi speed while N300 is 300mbps max wifi speed). How To Set WDS (Repeater Function) on WNDR3300/WNR3500?
You can buy two tp link Routers w8961 i think, both has WDS option. Very easy to setup. That way you will have wireless bridge to support long range of wifi at your home. You can buy one adsl+router and another router only.
