Hello. Recently got Fiber to our house and the speed is 1 gbps (1000mb/s) down and 100 mb/s up. which is one of the fastest internet on earth if Im correct. but seems like my download speed is capped at 1.2 mp/s when I download anything, it can be from Chrome,Steam,Origin u name it..
I currently have the Z170-A motherboard and I have installed the latest LAN drives for it aswell. My "Fiber" works fine but just seems like my motherboard cant handle more than 1.2 mb/s download? Do I have to get a networkcard? since Im supposed to get aprox 100 mb/s when downloading on steam with this internet I currently have.
 


What kind of ethernet cable are you using? IS it connected directly to the modem? Is the a separate router? Also have you tried multiple devices?
 
In the last 7 years of me building computers I have never had a motherboard not be able to handle 1 Gbps speed through the network card for LAN transfers so I don't think the problem is there. Like Herc08 said, try another device. If you get the same result there then it has to be the modem/router or something is wrong on your ISPs end.
 

Nonono, ofc it cant handle 1 gbps. but it's capped at 1.2 mb/s. back when I had my old MOBO and didnt even have fiber I had 1.7 mb/s at download. when I upgraded and got my new MOBO the (Z170-A) which I got a year before I got the fiber it was locked on 1.2 mb/s aswell. so what Im trying to say is that it was the same download speed 12 months ago when I didnt have Fiber and today it's the same thing.. capped at 1.2 mp/s My phone can now download at aprox 3-4 mb/s when I got fiber and it was on aprox 1.6-1.7 mb/s before which has doubled it. same on my Mothers laptop. my motherslaptop has like 60 mb down and 60 mb up so I bet that her Pc cant handle more than that. while my desktop is at 10 mb up and 10 down which is aprox 1.2 mb/s when Im downloading..
 


just a normal Ethernet cable. I dont know what model or version. and it's connected in to my ethernet port which is in my MOBO. and then about that router. the fiber routher that we got when fiber got installed in our house is connected to our Main router which is connected to my PC my mothers Laptop dads laptops etc, u name it.

 


so this could be a CAT5 cable issue. What kind of ethernet cable are you using. If it is capping at the same speed, I dont believe it is a motherboard issue. Are you using the same router?
 
Did you install the proper drivers for your ethernet port when you installed the motherbaord.

Sounds like the port might not be auto-negotiating and thus is in half duplex 10/100 mode and thus only going 10mbps (1.2 mBps).
Now not being able to auto negotiate could be due to a bad cable, bad driver, or bad nic.

Open Network and Sharing Center, click on yoru adapter and what does it say under speed??

Replace cable first (just because it is easiest), try downloading and reinstalling ethernet dr
 


All modern motherboards support up to 1Gbps connections. Older ones (roughly 10 years ago) only supported 100Mbps.
 


Download from origin 10MBS but on Steam it is 1.2MBS. I think this is steam issue. I've same situation here.
 
I solved this Issue by changing the Speed and Duplex setting to 100 Mbit/s Full Duplex in

Device Manager -> Network adapters -> Intel (R) Ethernet Connection (2) I219-V -> Properties -> Link Speed -> Speed and Duplex.


 


So then I was correct that it is not auto-negotiating.
Have you tested a different ethernet cable?
What model of router do you have?
Have you tried a different version of driver? Is this by chance a "Killer" network adapter?

I installed the latest driver from the Asus support site and simply changed the setting from 10 to 100mbit/s Full Duplex. There was no need to change cable or router.

 


You have a 1gbps connection and you have bandaid fixed your computer to do 1/10th that speed (100mbps), I personally wouldnt be satasified in calling that a long term fix (even more so considering you are probably paying a decent price for that fiber connection).
 


I agree however my connection isnt faster than 25mbit/s anyway. If you have a faster connection just select 1Gbp/s instead of 100mbit/s.

 


The OPs connection is gigabit, says so in his first post.
Not to mention that some people actually use their local network to talk to other computers/devices in their home, not just the internet.
Most all adapters settings have 100mbps full duplex but does not have a manual setting for 1gbps full duplex as that it is auto. So for the vast majority of NIC adapters you cant manually force-set it to 1gbps full duplex.
 


OP stated he has an Asus z170-a , using the latest drivers provided on the asus support site he should be able to manually change the duplex and speed settings even to 1gbps.

 
I know I'm jumping on an old post here, but I hope that is okay. I'm having the same problem downloading. I noticed it because it's the steam summer sale and I go to install a game and it tells me 28 hours to download (getting the same 1.2mb/s cap on steam). I followed the solution for the OP and mine was running on auto, but also detecting the 100mb/s. So that doesn't appear to have helped. My ISP is scheduled to come out on Monday night and check the modem. Any other ideas? I can't peak above 1.2 still.
