Operation:
•
Test the webcast well in advance of the actual event. If possible, conduct the test on the same day of
week and same time of day to approximate Internet conditions.
•
Disable all other Internet access in the meetinghouse.
This is a crucial step.
If you fail to do this, you
are likely to have failures with your webcast. Many members carry smartphones or tablets, and when
they come to the meeting, their devices automatically connect to the meetinghouse wireless Internet
due to previous connections they’ve made at church. Members will use those devices to check email
or browse websites, which will decrease the bandwidth available for the webcast and cause problems.
Users commonly report that testing during the week worked fine, but they had issues during the
broadcast – the difference is all the people who come to the meeting with mobile devices that connect
to the network. A software solution that will allow users to turn off the wireless access on the Cisco
881W firewall should be delivered in 2013. Until then, temporarily bypass the firewall (only for the
duration of the webcast) and make sure no other Internet connections are available, especially the
wireless access points in the building (the Cisco 881W firewall also has a built-in wireless access point).
The suggested method for the bypass (may vary by building) is to connect the feed from the Internet
Service Provider (ISP) modem (which generally goes directly into the 881W and then into a network
switch) directly into the port into which the webcast encoder is connected, making sure that all other
Ethernet ports in the building are not connected to the Internet. Make sure the 881W firewall is not in
the chain. It is not needed for webcast traffic – a direct connection to the ISP works just fine. After the
event, immediately reconnect the firewall.

There is a ~60-second buffer from the time the webcast starts until the receiving sites get the
feed. This helps to minimize transmission issues. The Test mode referred to has only a 10-15
