Lan slower than WiFi on just a pc

[Francesco_7]

Hello everyone, I just built a second economic rig with :

MSI b250m pro-vd
Pentium g4560
8gb ddr4 2133 crucial
Rx 460
500w psu from cooler master
Ssd and hdd

I built this as a second low price gaming, office machine, however the Lan connection is totally making me mad. It is slower than WiFi. In WiFi is got 1mb /sec download, with cable around 300/400kb. I also purchased an extra pcie network adapter from tp-link, the Tg-3468, but result is the same. It looks like the band gets saturated and became slower every second, I tried to to game online and I literally saw a the slow down affecting the gaming experience until it was unplayable. Weird fact is that when I plug the very same cable to my main pc, that is basically on the same desk as this one, Lan connection goes to the it's full speed of 2.5 mb/s stable and not saturation ever. The main pc comes with a msi z170a m5 motherboard and Lan is connected straight into the motherboard, no adapter. Any idea? I tried to Uninstall drivers and back on, switch cable, change cable, update windows, nothing works.. Maybe there is something blocking connection? Thanks

1| When you speak of a wireless internet connectivity, what is the make and model of your wireless adapter you'd used to connect wirelessly?
2| What OS are you on? Windows 10? If so then have you made sure your motherboard BIOS is up to date?
3| The Realtek RTL8111H chip for your NIC isn't a slouch so I'm guessing it's more towards the drivers. Mind you, which driver revision did you use for the Realtek onboard NIC?

On another note, the networking adapter you'd added later on doesn't officially support Windows 10. So if you're indeed on Windows 10, how did you install the drivers? In an elevated command?

Thank you for your reply,

1 the wireless adapter is the tp-link ac1200 model t4u

2 and 3 I have win 10 freshly installed, and mb settings sets to default, I haven't updated the bios of motherboard, thinking it is a new made motherboard for kabylake and so updated but I will give it a try for sure. The adapter has been recommended to me by a friend that got it on win 10 and he just plugged it in and surfed the web with No troubles, sadly not like me. For the drivers I've tried to install them the way it shows on tp - link(device manager) site and installed win 8 64 bit drivers but same results as the plug and play.

Thanks for your time, what do you suggest? @lutfij

He's asking about his LAN connection not wifi.

First of all even your physical LAN connection on your second computer is too slow. 2.5mb/sec? A Gigabit connection is 125 megabyte / sec so you add in overhead, about 110 megabyte / sec.

So the question is what are you plugging the NIC in to on the other end? A hub? A switch? A router?

Hello thank you.

I got a 100megabit connection from my provider and I live in a small and desolated little town with old cables, the best I reached is 2.5 stable megabyte for sec in download, with some peak to 3. I connected my pc by a power line, router is downstairs and a fast speed test with a laptop wired directly to router gave me the same download and upload speed. Is there any filter in win 10 or in msi motherboard I'm not aware of? I'd be happy to just have the same speed with the budget pc too. Thank you

OK. so there are a lot of factors here

1. Your connection from your ISP to your home. You are paying for 100mb (megabit) connection but you are only getting 2.5 MB (megabyte) down? Really? That's a rip off. Check your speed here: speedtest.net

2. Your router. What is the model of your router? How is it connected to your modem?

3. You say that your PC is connected to your router using power lines? So the powerline networking stuff?

There is no filter in windows that would slow down your speed. It has to be equipment related.
