This is for all the noobs out there like me when it comes to Ethernet. We just tried an experiment to connect a Linksys Internet hub/router to a distance of 525 feet to another house nearby. The idea was that we couldn't get wireless to work that distance (even with the use of a cantenna), so we would try the wired approach. I thought I read it could go up to 600 feet without a repeater or hub, so we decided to give it a go. I have color-coded, snap-together Leviton connectors at each end which have usually given me good luck. The idea was that we would pull the wire as a test, and, if it worked, we would then bury line in PVC conduit.
We found it was a no-go, so I rewired each connector again, just in case. Still, no connectivity. I would reason to bet that Ethernet craps out after around 400 feet. I can't put a hub at 400 feet, unfortunately, because we don't have a power source and can't run a line that long.
So if you're looking to wire large distances like this, you might want to keep this in mind.
We found we just briefly were able to pick up the wireless signal with a cantenna, but it lasted only briefly and dropped. We were not able to recover the signal again. Therefore, we think we need about 3 more cantennas -- one for each antenna on the wireless equipment -- and we hope that this will help us. We're using Cantenna.com brand cantennas. The wireless signal was fast and reliable, however, at about 400 feet, right before any stretch of trees. Therefore, we're hoping with some extra antennas, we might be able to make it through the trees.
