Ethernet cables - is there a length limit?

[john59]

I have one plug next to my router, downstairs front cloakroom, and the other is in my rear bedroom which my pc is connected too.

If making up cables then the pinouts and instructions are easily found on the web. Its a fairly easy process with some RJ45 ends and a crimping tool. Cut the outer cable 1.5 - 2" from the end, untwist the pairs, and align as per pinouts. Trim inner wires about 1/2" in length straight across. push into RJ45 plug ensuring each wire goes into each channel and up underneath the gold connectors. Then crimp.. re-crimp.. and that should be it. You should aim to crimp onto the outer jacket as 1. makes a firmer connection, and 2, means you've limited the possible interference to as short as possible on the non-twisted pairs.. I hate seeing badly made cables where theres 1/2 inch of inner wires showing outside the plug...There are always errors on them.. (Cat5 specifies so many twists per inch on the twisted pair, and even the connectors count ! )
For cable tidy I've found the stick on ties alot easier to the hammer ones [Concrete block walls] .. something similar to this.. http://uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=6292514

If you do need to go further than 90m then get an ethernet repeater, which boosts the signal (or plug in an ethernet switch if you've got a spare one lying around).
