Windows 10: 2 different 1 GB NICs on 400 mb internet connection runs slow

Ok, I am stumped, I have a 400 Mb internet connection, three other devices are getting speedtests in the range of ~480 Mb Down, My desktop (Old gaming rig) using two different 1 Gb NICs gets ~130 Mb down.

Troubleshooting steps, I won't list the details of all the Windows changes I have tried, but I have tried just about every one that seemed to apply. Tried known good cat 5E and cat 6 cables, tried different ports on th ASUS router, tried direct connection to Cable Modem, Tried updated and even downgraded drivers for both NICs.

I just can not think of anything else to try.

Specs for devices:
PC: ASUS m4a78pro with AMD Phenom 9500 quad core at 2200.0 MHz

NIC1: RealTek Semiconductor RTL8168B/8111B PCI-E Gigabit Ethernet Adapter On-Board

NIC2: TP-Link TG-3269 PCI adapter

Both are 1 Gb capable NICs. and they do show as being connected at 1 GB in the properties. So I am totally flummoxed and at a stand still in fixing this. If anyone has any ideas or needs more information just let me know. And thanks in advance.

LAN - 1 Gb/s on VM, 100 Mb/s on W10 HOST (HYPER -V)

Hi there

Both physical NICs are 1 Gb/s - Yellow led indicates 100 Mb/s, Green Led indicates 1 Gb/s
Am using separate Nics on VM and HOST.

Linux driver using physical Driver for the Nic (Nic 1). Windows using physical driver for Nic 2.

Intel normally has the most reliable and installable Nic drivers !!!!!. Wifi is another issue but I'm not using that on this machine at all.

Running Linux on HOST machine BOTH Leds are Green (indicating 1 Gb/s)

Native Windows on Host without HYPER-V -- still indicates Yellow Led (100 Gb/s). I physically carried server to Router and attached small piece of LAN (0.5 metre) directly to Router. -- Router indicates 1 Gb/s while LED on Nic adapter was only 100 Mb/s so definitely something wrong with driver / hardware compatibility. I tried BOTH NIC's (2 physical NIC's on Host) - same result so it's not just 1 NIC being defective.

I think it must be a HOST driver issue -- am looking further. !!

Thanks for the info.

Curious -- 99% of my problems on Windows seem to be with Networking in one area or another !!!!!.

I tried restoring both a W7 image and XP image individually (to HOST machine) - Lan adapter Led immediately switched to GREEN at 1 Gb/s for BOTH OS'es so definitely W10 doesn't like my driver or there's some hidden / obscure settings I need to change.

Internet running very slow


Hi, i am wireless, but did connect with wire and made no difference. Also ps3 is running fine so no probably with connection. Have listed current updates below. It says downloading, but they never seem to download






Also have this from download history





This is the version details of windows





This maybe an old version. When my computer downloaded the anniversary update i recall it messed up my internet on that occasion, so i went back to the previous version

 

Windows uses wrong NIC in a dual NIC setup, Ignores metric at times.

Well can I manually force it to not do this or force it to a specific mode? I mean it works fine 90% of the time but then seemingly randomly Windows will just push all traffic that previously went on NIC 1 to NIC 2. So I can use NIC 1 and NIC 2 simultaneously for hours and then suddenly Windows will stop using NIC 1 for all normal traffic and try to use NIC 2 instead, even though my firewall blocks all applications from using NIC 2 (which I think it should realize and start sending the traffic via NIC 1 again)

It's not actually two different VLANs, it's the same LAN, same subnet. Just that all applications should take NIC 1 to reach it and Tixati NIC 2 to reach it. The routes reflect this by NIC 1 and NIC 2 having the same settings just that NIC 1 has a much lower metric which should mean that Windows should use NIC 1 instead of NIC 2.

Nothing like that is done with the VPN, the VPN part is working great. The VPN is running on the router and has two connections connections and the router routes traffic from NIC 1 to VPN 1 and NIC 2 to VPN 2, so everything there is working great. The thing that isn't working is the dual connections between router and computer, I don't want Windows to load balance or bridge or fallback, I want Windows to treat them as two different networks of which only one should be used by it which is NIC 1 (But NIC 2 should be enabled and available so that Tixati can force itself to use it)

Although it sounds like Windows just won't let me set this up? Sounds like it forces what it thinks is best for my system even if it isn't? I guess I'll just have to disable/enable NIC 1 every time it happens then.

Thanks for answering. =)
