We're looking at the possibility of somehow connecting the router in the vicarage to the church office to enable the PC there to be on the internet and to use the fancy office printer from the vicarage. Straight line distance is perhaps 30 metres.
An Ethernet cable run would be less than 100 metres, across the 2-metre gap and through the church buildings, to the office; though this would be quite a significant routing exercise, and would need the capability of affixing RJ45 connects to the cable.
The other solution would be to use a wireless link. 10Mbps would be perfectly adequate. Cost is important, i.e. low cost.
I'm not sure whether power line networking is feasible. The main 3-phase supply comes into the church and one phase, IIRC, goers to the vicarage, the other 2 phases are used for the church and the hall, associated rooms, and the office. So I'm not sure whether power line networking would work across different phases.
Assuming we can get the Ethernet to the office, would a simple 4-port hub be all that's needed there?
Any helpful thoughts would be appreciated.
