Wired and wireless internet into second building

[Maineman]

We are a church. We are looking to get internet into a second building cheaply. Tried a wireless repeater but because the building has aluminium siding it didn't work.

Second option is to run a coax cable to the second building. Thinking of running the service provider coax cable through a splitter. One output would go to the modem / router in the first building and the other to the second modem / router. This way we should have wired and wireless internet in both buildings.

We have a new Cisco / Linksys E4200 2.4 / 5 GHz wireless N router in the first building and plan to use the older Cisco / Linksys 2.4 GHz wireless G router in the second building.

The distance to the second building is about 100 feet. We want an internet connection strong enough to stream video.

Figure the cable and splitter will cost about $30. Anyone see a problem with this set up or a cheaper way to do it?

Unless you pay your cable modem provider for a second Internet connection, you cannot usually just use a splitter and coaxial cable.

You can run a CAT 5e cable for that distance, connecting it to an LAN port of your main building router and the other end to your old router that you would configure as a wireless access point by turning off its DHCP service and assigning it an IP address on the network either reserved in the assignable IP address range of the DHCP server on the main router, or static outside the main router's assignable IP address range.
