Network cable test ok but not working

By kim007b ·
I have a new network cable in my house which is OK when I use a LAN cable tester. But with multiple laptops, the cable has no network when connected to my TP-link switch.
The web interface of my switch indicates that the cable is connected (1000MF) but it only shows to receive packets (Rx) but not sending packets (Tx)
Green/orange LEDs of switch and laptops are not lighting.
I already cut the cable and put new connectors on both ends without any change.

Any ideas what might be wrong, what can I do?

The first thing you need to look at is does the cable run close to or touch any electrical cable?

Is it running over a Fluro Light?

Is it close to a Microwave?

All of those things can cause interference but probably the most important thing is Does it need to be a Crossover Cable? Your description sounds very much like a straight network cable is being used when a Cross over is required.
