My (small) apartment building has 1 main cable that hooks into a wireless router supplied by the internet supply company. Out of that router we have 3-100ft cat-5 cables running into 3 apts. Off of those wires are 2 additional wireless routers and one is connected directly to computer.
One of the tenants connects to the internet by the wi-fi from the central router and the other 3 connect via the lines run into each apt.
My problem is, the internet cuts out about 2-3 per day. One of us goes out into the hallway and un-plugs the central router, waits 30 seconds then plus it back it. This solves the lack of internet problem, but only temporarily.
I talked to our internet provider and the only thing the guy could think of was that maybe there was signal interference between the wireless routers.
In case I wasn't clear, here's a breakdown of the layout:
Main Line > Central Wi-Fi Router
Tenant 1: Central Wi-Fi Router > wi-fi receiver
Tenant 2: Central Wi-Fi Router > cable > desktop
Tenant 3: Central Wi-Fi Router > cable > wi-fi router > laptop
Tenant 4: Central Wi-Fi Router > cable > wi-fi router > laptop
Also, in case anyone is wondering, this is not illegal. I cleared with our provider.
in a way of checking i would suggest turning off all 3 indoor routers and unplugging all 3 cables from the main router and knowing if the internet ever cuts out on the main router. if it does then its from the main router but if it doesnt the its probably interference.
also check and make sure all 4 routers are all on different channels using say channels 1,3,6,11
let me know how it went.
