Sonicorbiter players and servers connect to your network with an Ethernet cable. They do not have Wi-Fi. If there is no Ethernet connection where your system is, the best fix is to have one installed. A local electrician can do that for a reasonable price.
A good alternative is a pair of powerline adapters. They carry your network over your home's electrical wiring: one adapter plugs in near your router, the other plugs in near your player, and an Ethernet cable connects each one.
The TP-Link AV1000 Powerline Ethernet Adapter Kit (model TL-PA7017 KIT) is a good one. It comes as a pair with two Ethernet cables, each adapter has a Gigabit Ethernet port, and it works as soon as you plug it in with no setup.

The adapters work together out of the box. To make sure no one else's powerline adapters can join, for example in an apartment building, pair them: plug both in near each other, press the Pair button on one for 1 second, then within two minutes press Pair on the other for 1 second. When the Powerline light comes on, they are paired and you can move them to where they are needed.
For the best isolation between your network and your music system, you can add an opticalModule between the adapter and your player.
