Thread shows a classic symptom: short hand‑made Cat‑5e patch cords work, but longer ones go flaky. rightly pushed isolation, and later reported a fix but did not give details. The likely root causes are termination and connector choices that only show up as length (and therefore signal loss/crosstalk) increases.

Common physical problems to check: wrong style of plug for the cable (solid‑core vs stranded), split pairs (right color order but pairs broken), too much untwisting at the termination, conductor ends not fully seated under the plug contacts, nicked copper, or cheap plugs that fail to bite stranded conductors. For gigabit links, split pairs and bad crimps are especially harmful because all four pairs are used simultaneously.

A short, practical test sequence that complements earlier advice: swap in a known good short patch cord to prove the ports are OK; inspect both terminations to confirm the same wiring standard (T568A or T568B) is used at both ends; keep untwist to a minimum (roughly under 1/2 inch) and ensure insulation reaches inside the plug so the metal contacts touch copper; use a simple multimeter continuity check to verify every pin maps to its mate and that there are no shorts between pairs; if needed, reterminate with a plug rated for stranded cable or terminate to a punch‑down jack and use a short patch cord.

If problems persist after careful termination, switch to pre‑made certified patch cables or fit higher quality stranded‑wire RJ45 plugs / keystone jacks. Good step‑by‑step termination photos and wiring diagrams are available in many online guides such as and background on pair usage in Ethernet over twisted pair.

You have a wire tester to test the cable after you make it? Ethernet has a limit of 100m so you're not breaking that

Thanks dude,,, But currently i dnt have Tester type of thing.. so Any desi Jugaad to sort out my problem.

well if you're using the same devices to test the different cables, then your crimping isnt being done properly. It is best to have a tester to see if a wire comes up short, as thats all it takes. Check each end of the cable, see that each wire is contacting in the metal in the RJ45. You can also see a good physical layer connection is if there are green lights on the network ports of your devices.
