It's easy to crimp cables yourself. Just get a crimper, some RJ45 plugs (CAT6) and a cable tester. The follow directions here.
Crimping Ethernet cables. These tools and cables are inexpensive. Lay the cables in a conduit/casing away from electrical wires to prevent interference. Do not string the cables outside the home for the same reason. Make sure you buy good quality 1 Gb switches not hubs.
I created a wired home Gb LAN, a backhaul of sorts, in early 2011 myself using
D-Link CAT6 cable and connected my
router, APs,
NAS boxes, and home PCs to it. Wi-Fi is used for streaming or listening on portable devices while all the serious stuff like data backup, torrenting, etc is over wired LAN. I have strategically placed 3 Wi-FI
AC routers working as APs (using different SSIDs so I can select manually if required) all over the home. No hassles with signals strength anywhere.
This is a permanent solution instead of getting into hassles with range extenders or repeaters which work in a pretty unpredictable fashion. And now my next project is to upgrade to a 10 Gb LAN.
