Can't see interesting packets on my network

view story

http://www.backtrack-linux.org – I am sniffing on my super hub router with my Alfa network (chipset RTL8187) and using Backtrack 5 dual boot. I have yet to see http packets in wireshark, only SSDP and ARP packets and even when I try ettercap -G (etter config edited) I only see TCP packets. I have put my wireless on monitor mode and tried with and without Mon0 yet I see no useful packets. I have also tried driftnet and I see no images. Dsniff, ARPspoof and SSLstrip yet again I see nada. What am I not doing or doing wrong? Thanks (HowTos)
