[ns] Wired-cum-wireless-->error

[Andi Nugroho]

Hai,
I'm a college student from Indonesia. I'm building a wired-cum-wireless
project sending a multicast packet. I'm having this error on my simulation
:

root at andinugroho:~/ns-2.32/ns-allinone-2.32/ns-2.32/puma# ns tandi4a.tcl
num_nodes is set 5
warning: Please use -channel as shown in tcl/ex/wireless-mitf.tcl

I'm seeing you guys ever had the same problem as i am. Do you have any
solution
for this error??
Here's the topology :

    s1                          /s1
      *                        /
                              /
  s2*    AP------Voice gateway------ s2
                     (Mux)    \
                               \
    s3*                         \s3
