JCB were recommended to us by another fencing company that does not do chainlink repairs. I called JCB around 9am on a Tuesday. They arrived to our shop at around 1pm to give us a quote.
Network Hub. A network hub is designed to connect computers to each other with no real understanding of what it is transferring. Typically, a network hub is used for a private network, one that does not have any connections to sources other than local computers (meaning, no Internet access).
A gateway is  a node (router) in a computer network, a key stopping point for data on its way to or from other networks. Thanks to gateways, we are able to communicate and send data back and forth. The Internet wouldn't be any use to us without gateways (as well as a lot of other hardware and software).
