1 gbps full duplex not working

[lolsmurfzs]

recently i heard that i could change my internet speed from 100mbps to 1gbps so i thought, let's try it. but it didn't work.

when i changed it in the "speed and duplex" settings my pc couldn't connect to the internet anymore and i had to reinstall my network drivers.

my MB: gigabyte g1.sniper B7

am i doing something wrong? because i really want this to work.

you cannot just change the speed and get 1gbps internet

if the cable that enters the NIC is 100mbps there's nothing you can do to make it 1gbps - some 100mbps cables aren't even wired with all pairs; 1gbps needs all 8 wires, 100mbps uses only 4

All the devices that your pc connects to need to be capable of 1 gbps speed, and you need to use proper 8-core ethernet cables. (look at the connector, 8 wires= 1gbps, 4=100mbps)

the cable has 8 wires so that's not the problem i think.

Your network card is capable of 1gbps ... but the device at the other end of the cable also has to be capable of 1 gbps. If your cable modem or router has only 100mbps ethernet ports, then the maximum speed will be 100mbps.

 

Ethernet cables have 8 wires, but they also have to wired properly at both ends in order to transfer at up to 1 gbps. Usually this is not a problem, but rarely and especially if cables are made by hand instead of being bought from store ready made, the wires can be arranged in the connectors the wrong way for 1 gbps.
