Do you have a link light? Tried a different patch cable from Notebook to wall, or at least eliminated it as a possibility by trying that cable elsewhere? There is also the physical line length limit. Since you always have spare cable in the wall, just redo both ends again. Cheap testers are like ohm-meters, they do not tell you if data will pass and cannot be used to certify a run. Can you borrow a proper tester? See these sites for some tips. http://www.abletronics.com/cat5data.html

On an RJ45 end, the sheath is inside the crimp for strain release. I hate sloppy ends, and see them way to much. Do it right, use google to do some reading.

I got my crimping tool, rj45 crimp plugs and a flush box at DSE. I put the flush box at one end of the cable and an rj45 plug at the other end. Tested with LAN cable tester (also DSE) and every pin is connected in the right order. Plug the rj45 plug end of the cable into the switch and plug the laptop into the flush box which is mounted on the kitchen wall. Lappie sends DHCP requests but gets no answer. All cables are connected correctly according to lan cable tester. So why does it not work? Could it be that I untwisted too far when poking the wires into the crimp plug or the flush box? How far is too far? What else can anyone think of. How is this linux related? Every box on the lan runs linux of course! Yuri
