Router features fast connections yet performance remains slow.

Cat5E, Cat6, Cat6a and Cat8.1 or Cat8.2 all handle gigabit and 2.5GbE over distances up to 100m. Cat6 can deliver 10G up to 55m or 5G within that range. Cat6a supports 10G and shorter distances up to 100m. Cat8.1 offers 25GbE up to 30m, while Cat8.2 provides 40GBE up to 30m. Cat7 isn't an official standard and requires TERA connectors, which don't work with RJ-45—so claims about Cat7 are false.
Additionally, it's uncommon yet possible. Examine the connector on your computer or laptop closely, confirming each of the eight pins is aligned correctly within their designated slots and remains flexible when pressed. Within each connector there are eight pins, functioning similarly to springs—they are engineered to flex and rise when you insert the network jack. Occasionally, a pin may bend excessively, crossing over the barrier and maintaining contact with another pin, which can cause a short circuit. You might need to gently adjust or use a needle or tweezers to realign each connection if necessary. Also verify the cable and wire arrangement, as this impacts performance at 1 Gbps speeds. Ensure the internal components of the Ethernet port or jack are firmly gripping the wires. Over time, the blade-like parts inside the plug may become loose, reducing their ability to connect properly with the wire inside. Make sure both ends of the cable display the correct wire sequence (consistent order is acceptable as long as it matches on both sides). A cable where the first version appears on one end and the second on the other is known as a crossover cable suitable for 100 Mbps or slower Ethernet cards. This type of cable allows direct linking between two computers without a hub or switch, enabling a straightforward connection between two network cards. Only devices supporting up to 100 Mbps require this feature, and typically only four wires are altered at one end since such cards use just the first three and the sixth wire. The fifth and sixth wires were historically used in office environments for phone lines, eliminating the need for dedicated cables, while the seventh and eighth wires often remained unused. A 1 Gbps card can automatically detect a direct link between two cards and rearrange its internal wiring to function correctly, making a crossover cable unnecessary. In fact, using a crossover cable might interfere, as gigabit standards depend on all eight wires working together; a crossover would only flip half of the connections, which is incorrect.
