Streaming / IPTV

[UDAY UKIDWE]

I have WIFI routers (DLINK ADSL for MTNL Broadband), Lyksys , And Motorola VOIP adapter.
Also have Sharp LCD AQUOS TV with HDMI and VGA inout ports
have Vonets VAPG11 for internet sharing

I understand I need a WIFI STREAMER (e.g. ROKU 2XD) which will enable me to get IPTV and Streaming my LAPTOP's audio video and screen.

Would like to have experts comments / suggestions for other alternatives

Thanks
