Cisco 881W - get to know!

We are just starting to have the 881W installed in our stake and have 3 so far.
It would be nice as STS to have a nice manual on the 881W, but I don't.
So could any one put any info they have on the 881W here as a support.
I am going to research it myself, but any help is appreciated.
I also need to look at how to disable wireless so that when we have a web conference we can consider doing that to restrict the bandwidth available for the conference.
Whether that be us broadcasting our own stake conference or receiving a conference.
At the stake centre, we have at most 3.5mbps.
So any help with the 881w would be great.
I also need to look up the BT business hub we use, BT model 2701HGV-C.
All of this is for the future, at present it works well.

You can find some information here. But note that the church controls the device remotely, so a manual will be of little use. Basic church instructions can be found here. By in large, your job is to insure that nobody plays with the cables to bypass it.

That advice has been to simply remove the antennas. That will limit it's range. Otherwise you'd have to call GSC, but it's been suggested that they're not too accommodating of temporary shutdowns.

http://tech.lds.org/wiki/Wireless_networking_(meetinghouse) also for useful information about additional wireless configuration.

We cannot disable the 881W wireless from our end. The best choice, as already stated, is to remove the antennae to reduce the range. When the LDS Account credentialing is implemented there will be an ability for an STS to disable the wireless through an administrative website application.

Well-said, jdlessley

For now, there isn't a way to fully disable the wireless on the 881W, but we are working on a tool that will allow this in the future.

Just wondering if anyone could tell me if the Cisco 881-W routes traffic over VPN? We have had many issues with broadcasting from our stake center to other buildings in our stake, both General Conference and Stake Conference. One of the former STS thinks that one of the problems could be that all of the traffic is routed over VPN. Any ideas would be helpful. I am planning on testing the network during the times that we have really noticed the problems to see what configuration(s) work best for broadcasting. If I find anything significant I will post.

VPN is primarily used for the GSC to access a local network, and more specifically the 881 or any WAPs for remote access. Outgoing and incoming traffic use the standard Internet interface. The Church uses VPN for other tasks but not for general Internet use.

What are the problems specifically? They may be the same others have experienced and those who experienced those issues may have solutions to offer.

Webcasting and PVC do not use VPN.

Removing antennas does not work as there are repeaters in the building.

When you say "repeaters" I assume you are referring to wireless access points such as Cisco 1041n devices. While that's true in many buildings, it's a simple matter to disconnect them for events where you want to limit wireless access. They will be plugged into the 881W firewall, and will almost always have a power injector that supplies their power via Power over Ethernet. If you disconnect the cables that go from the injectors to the WAPs, you will remove both data and power to the WAPs, and they will no longer be an issue.
