if i hook up my ethernet cable that goes into the router to a coupler with my ethernet cable i get close to gig speed up and down.

when I dont bypass the router I get .1 mb upload, gig download

tried to change my speed and duplexing to auto negotiate, 2.5gb full duplex, 1gb full duplex

always same result of terrible upload

on wifi i get 300/100

windows says my drivers are up to date, even did all the optional ones.

router fw updates automatically

my roommate says he never has issues with the ethernet, we tried swapping ports and its only my computer that has issues.
his speeds arent optimal though

Wonder if it has anything to do with the Cat type of the cable you are using.

cat5e into the router and into my computer. Ethernet is perfect if i bypass the router

sorry to confirm, your computer connected directly to modem it gets full speeds but when connected to your router it doesn't? but if you set up another device with the same cable, same port, it gets the full speeds?

other than that:
windows updates are different than your motherboards updates
post what motherboard you're using
google your motherboard + drivers
download and install LAN drivers
try that
also check motherboards site to check advertised rates for ethernet port

That or he has the wrong Lan driver installed on his computer.

May want to visit the motherboards website and see if they provide a driver thats more up to date than what is installed.
Makes a huge difference.

Also yeah Ethernet cables Cat5 , Cat5E , and Cat 6,7,8,9 all make huge differences in speed, and durability.
Sometimes Internet Cables get so old they can pinch or even Dry-up , causing loss of Quality / signal.

I guess ill say resolved, its a shitty nic card.

if i bypass the router, perfect speeds.
my laptop and roommate comp having no issue whatsoever with any cables/ports on the router
no weird settings on router messing with my mac, dns is the same.

so i found this which sounds like it will be the best solution other than getting a new nic card

currently i updated my driver then rolled it back and capped speed to 1gbps full duplex and im getting 1006.4 Mbps download, 741.4 Mbps upload
