confused about speeds

[lolsmurfzs]

For the longest time i've had a 90 mbit download speed though we pay for 300 mbit down (recently upgraded to 400 mbit) but i still recieve 90.

i'm confused because my brother upstairs is connected to the same switch but he's getting the 300 mbit down we're supposed to get.

i have no idea what kind of switch it is but every port is the same (i tried switching to other ports with no better result).

also my motherboard supports 1000mbit so that's not the problem.

as you can see in the picture the partnet isn't capable of higher speeds, but how is my brother upstairs getting higher speeds?

(i also tried manually switching from auto negotiate to 1.0 gbps full duplex in speed and duplex settings but that doesn't work)

cables maybe?  some old cat5 cables cant support gigabit, or it could just be a bad cable.  or maybe your brother is just using all the bandwidth.  but that wouldnt explain the links status only bee 100mbps

cable could be the case, i found a test which says it's 225 meters but i'm pretty sure it's 25 meters at most.

the type of cable could affect the speed. also your network card could affect the speed.

Replace the cable. Also you need Cat 5e or Cat 6 to do Gigabit. Also no Ethernet cable can be longer than 100 meters.

Sounds likely that it is the cable if devices on both ends support 1000 full duplex.  Replace the cable with a premade cat5e and retest.

Can you post a photo of the pin side of the connector? Both ends  so we can see the colors and order
