Realtek PCIe GbE Family Controller #3 stuck at 100mbps

[Carson Tate]

my ethernet is stuck at under 100mbps when i get 400 mbps on my phone, i have tried setting the speed and duplex at 1.0 Gbps and nothing worked, it says it is rated at 1000 mbps but i somehow cannot get it to more than 100. ive updated the drivers to the latest, my ethernet cable is a cat 5e cable, ive checked the router settings and ports, nothing seems to work. my motherboard i have is the b350m bazooka if that gives any help. I have seen multiple people with this problem and somehow still cannot find the solution.

Is your Router actually 1Gbps ported or 100Mbps Ported? You didn't mention this.

how do i check this

[Alireza]

check the specification

it should say its 100 Mbps or 1Gbps

It should say so on the Box,..
Or...
Whats the Router Manufacturer and Model?
I'd look it up to find out.

Yeah it's a Gigabit Router.
5 Ports with 1Gbps Capabilities

Have you another cable to test?

i tested another cable and its still capped at 100mbps, i have this screenshot of it at 100mbps, the odd thing is that the motherboard stated that it supports up to 1000mbps

Unless the motherboard is pretty old I would suspect it has gigabit as well. Have you tried updating your lan drivers?

i have updated the drivers, the msi b350m bazooka that i have says it is capable of 1000mbps

This is with a new cable correct? Is there anything between the computer and the router/modem like a switch? What is the length of said cable?

ive tried multiple cables, cat5e and cat6, both around 10 feet, the ethernet is directly connected to the router and to the pc

Try a different port on router.

Try resetting the router to default settings.

Try making a bootable linux usb drive and see what speeds you get on it

Update bios

check bios settings

If all else fails consider it could be the ethernet port on your mobo and try a pci-e / usb one.

Just a few more things to test or look in to

ive tried every port, updated the bios, and we just got the router 2 days ago. might just have to get a new motherboard since i was gonna get one soon anyways

Does the router perhaps have Energy Efficient Ethernet or other power saving technology?  If so, is there any option to disable it?  It can cause issues sometimes.

no, this happened with our old router and is still happening, i got a ethernet card to plug into my pc, and even that didnt work, 100% the motherboard and/or ethernet inside the motherboard

You're connnected directly from PC to Router or do you use any wall plugs?
check realtek drivers

If you tried differend card it has to be cable. 

New driver installation should reset all nic configuration like duplex, auto negociation etc.

What kind of ethernet card?  If it was the same chipset as the onboard then it could be exhibiting the same problem.  This is why when people want an extra PCIe ethernet card Intel models are usually recommended as they typically are more reliable.
