Internet Security setup

[ronney]

The following set up has worked great for us, but now we have come to the point that we need to secure our DSL connection, and I’m not sure how to do it. How do I secure internet connection for the following scenario?

Building A (office) houses a Engenius ESR350 Dsl modem/router. It is connected to a network switch. Building A uses the ESR350 as it’s wireless internet connection. On top of Building A is a Engenius ENH-210EXT. It is in Access point mode and is hardwired to the network switch. It is the main wireless access point for surrounding buildings. Building B has an Engenius ENH-210EXT mounted on the roof in bridge mode. It receives its signal from Building A’s Access point. Building B’s Bridge feeds via hard wired to 2 Engenius EAP350 Access points inside building B. That’s how building B receives it’s Dsl internet signal.

I'm not clear on what you mean by "security." Could you be more specific as to what you want to do? Do you need to password protect your wifi? Do you need some sort of login system? Do you need to keep part of your network separate from the rest?
It would also be helpful to know what sort of budget you have if any.

I need to password protect the wifi. Thanks.

And all of your WiFi is currently just open?

It looks like Engenius offers a program called EZ Controller that may allow you to change your wifi settings on all of your devices at once. I've never personally used it, but I would try it out.

Yes we are in a rural area and a open wifi was not a problem until growth started to occur around us. When I try to password protect the dsl modem/router and try to connect to the internet in another building via the bridge and access point it does not ask for a password, and does not connect. I guess what I'm asking is how to pass the "password protection" from the DSL/router through the other devices?

A lot of the setup depends on the particular software your access points use. In general, what you need to do is log into each access point/bridge, change your WiFi security to WPA2 (or just WPA), set the key type to AES, and add a password/pass phrase. Use the same password for each device.
This can probably be done all at once using the software I linked to earlier. If you can learn how to use that, everything will be much easier to manage.
