Sir,kindly advice me as to what device i should buy in order to be able to use wifi throughout my house(2 storeyed).i am having the conventional D link ADSL 2+ Router(GLB-502T) and is using MTNL broadband connection in mumbai.Also my laptop has wireless facility (HP Pavilion 6114tx),but the range is too short(doesn't even catch in the next room).Please suggest me a product for home use(Not very costly & value for money)
