Show only HTTP traffic in Wireshark
In the filter field, type http
(lowercase!). Tested with WireShark Portable 1.10.7
Some basic filters
!http
shows all traffic which is NOT httpip.src != 196.168.1.1
shows traffic which is NOT from this IP sourceip.dst == 196.168.1.1
shows traffic to this IP destinationip.addr == 196.168.1.1
shows all traffic which has the specific IP as source OR destination
To exclude SSDP/UDP: http && tcp
