Daisy chaining two RJ45s for use of only one laptop 1

[pofadda]

Most Search results re 'daisy chain' refers to switches - I want clarification about the wisdom, indeed the possibility of daisy chaining two sockets on a run from a switch. A link to a clear answer will do as well. This connection is only for ONE laptop that might be moved between the rooms, not two machines.

I have run a cable to a socket but when I tried to punch in another cable to run to another room, the distant socket looked a mess on my continuity tester! This could be a basic protocol mistake or bad cable-punching. Assuming my punching is sound, might I retrieve the situation by fitting an RJ45 to the second cable, routing it to the outside of the face plate and plugging that into the socket via a splitter plug?

Yeah, sounds like a bad job punching down.

I have the equivalent running, patch cord to a box with 2 rj45s hooked up to each other, then another patch cord to the far computer. No issues but it is only about 40 feet to the furtherest.

I've extended runs before with no problem but I'm a believer in doing the distance runs with solid into jacks.

Drat! I was hoping it wasn't poor workmanship!

But, just to be clear, did '... into jacks' mean the same as my 'plugging that into the socket via a splitter plug'? Or have I missed something?

Into jacks with solid wire meant into punched down cat5 modular sockets rather than using modular plugs which would be used with a splitter.

Bear in mind that if you don't have all 4 pairs available on a connection, it will only do 100Mb/s, not 1000Mb/s.

If he's using cat5 wiring then he'll only get 100mb anyways.

He never said he was using cat5.
This being 2011, that would be pretty unusual, too.

I still see cat5 being installed in many smaller and mid sized businesses

That's funny. The cablers that I work with haven't used Cat5 since the 90s. They don't even keep Cat5E in the back of their vans any more, because Cat6 only costs a couple of cents/metre extra and it saves them having to keep two reels of everything. I wouldn't be too impressed at finding Cat5 anywhere I was having to do work.

Back to the OP, it appears that he had an existing cable from point A to point B and then ran a new cable from B to C and tried to punch both cable at point B onto the same keystone jack - either the top wire is making poor contact, or it spreads the teeth enough that the lower wire no longer makes good contact. (Or he could have cut the existing wire in the middle trying to connect the new jack to both sides, but the same 2-wire issues remain.)

What I would do (for myself, not for a paying client) would be to put 2 separate jacks at the midpoint - connect them with a short patch cable when the far jack is to be used. Actually I would probably go as far as connecting them with a cheap 4-5 port switch and connect the laptop to the switch when used at the mid-point.
