WiFi can be configured in many different ways, the most common of which has one end acting as an "access point" -- sometimes as part of a router -- and then one or more devices such as laptops connecting to it. But sometimes you have devices without their own wifi (such as a ooma hub or telo) or there are other reasons such as a need to use an external antenna to get good enough signal coverage.hhvision wrote:how can use the WiFi as a bridge between utility area & the office & place the hub in the office.
In these cases you use another access point at the receiving end and put it in "access point client" mode. Then instead of broadcasting WiFi, it receives the WiFi which you can then feed to a switch. Not all access points can be configured in access point client mode, and some which can will only work in that mode when the broadcasting AP is from the same vendor.
So if you have WiFi in your router now, or have an existing AP, then you may want to first see if that vendor has an AP which can be configured in AP client mode. If not, and it can take third-party firmware, you may be able to do it that way.
My favorite device for doing AP client mode is one from SMC called SMCWEB-N. It seems to be able to work in AP client mode regardless of the broadcasting AP, and even has its own 4-port switch included. You would configure the SMCWEB-N for the security wireless settings on your router or AP, then plug the hub / telo into the switch on the SMCWEB-N.
WiFi "bridge mode" is essentially the same thing, but the broadcasting AP will reject any connection except the remote AP in bridge mode. That effectively creates a bridge between two network segments but without any risk of other devices also using the network. Again, typically, this requires two devices from the same vendor.
