Before thinking to broadcast your IPTV Encoder / Server to a Network,
please be sure that your Access Point (Wireless Equipment) configured and support multicast.
If not, then all any connection through the wireless access will be interupted.
Or even worst disconnected.
Standard IPTV bandwidth for 1 channel (represented and streamed with 1 Multicast IP Address) is adjustable depends on the output rate, my case to have a normal view is set to 12.5 Mbps
Multicast Rate need to be pre-configured before transmitting.
Some access point doesn’t support this feature.
Asus RT-N-10 has this feature and can be set up to 54 Mbps (which is can support up to 4 Channels).
Please note that data not included 
Unless you do not need internet.
One thing, even if the multicast rate set to 54 Mbps…
Why my laptop received on 6 ~ 8 Mbps ?. (of course the screen not as smooth as using Ethernet.
It might be the embeded wireless equipment is not supporting high speed multicast ?
