I suspect the wiring as it&#8217;s all new and some patch cables were created onsite.   A new server only connected at 100mbps and when the patch cable was replace with a new, store-bought cable the connection increased to 1000mbps.   I suspect their &#8220;Electrician&#8221; does not know enough about ethernet cabling, creates patch cables that have split-pair condition (3+4,5+6 instead of the correct 3+6,4+5) and uses a cheap cable tester that can&#8217;t test for split pairs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here are the least expensive testers i can find that test for split pair condition.

In our case the home-made patch cables passed the continuity tests but had split pairs that caused a bunch of network strangeness, low connectivity speeds and some devices on longer runs that wouldn&#8217;t connect at all.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are more expensive units that can tell the distance to a cable break.   I have used VERY expensive units like the FLUKE OptiView (a tablet with built-in tester!), they are nice units but unless you are wiring full-time, I&#8217;ll recommend you RENT a more expensive unit when required.  Knowing WHERE a conductor is broken doesn&#8217;t make replacing the cable cheaper.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A recent new facility is having a lot of problems with wiring, Wifi APs going offline, and high latency.
