We are a small school. I am getting Internet service from Comcast - this is the ONLY service available at my address. We are having intermittent issues with web site availability. The connection is reliable because I am running my SIP telephone service over it without issue.
The problem is with web site availability. A student can be working through an online course and suddenly loose connectivity to their particular web site. I can get Verizon FIOS service at another building about 1/4 mile away. I am considering getting FIOS service at that building and then set up a 900 mhz bridge to my main building to provide a WAN fail-over for my main network.
My question is about WAN failovers. How exactly does that work? I have a SonicWall that has the option to incorporate that. Does the failover kick in only when my main data connection drops completely or would it kick in when the main connection is unable to reach a web site?
Does this sound like a reasonable attempt to solve my Internet unreliability?
