s about Ethernet cable connections
You followed the correct pin configuration, but the connection is being interpreted as a 100baseT instead of a gigabit one. Check the switch, router, or any other devices connected to ensure they support gigabit speeds. Also verify the cable’s labeling and physical connections for accuracy.
I tried the cable tester and everything functioned properly, yet I still don’t understand why it wouldn’t. It seems there might be another issue.
Technically, the cable should function properly as long as the crossed wire is connected identically at both ends. Both A and B will still reach their destinations. The recommendation stays the same: re-terminate with the correct 568B configuration.
They weren't opened at all; I just placed them one after another beside each other.
original 100 mbps setup placed positions one and two for a pair, while three and six handled the other. one side received, the opposite sent. this explains the two wire orders—t568-a and t568b. when you build a cable with one end at one device and the other at another, it creates a 100mbps crossover connection, enabling two computers to communicate directly without a hub or switch (transmit goes into another PC's receiver, and vice versa). The inner wires (4 and 5) were occasionally used for telephone lines to avoid separate phone cables, later also supporting passive power over Ethernet. Gigabit technology uses the remaining pairs as well, making correct wire arrangement essential. Incorrect installation will prevent functionality. For cables exceeding CAT5e standards, the pairs are physically separated along the plastic-reinforced casing. Gigabit connections cannot (and shouldn’t) use twisted pairs from these two positions—gigabit cards automatically detect pairs, eliminating manual setup. Proper crossover for gigabit requires flipping all four pairs, not just two.
