Shasoosh Posted December 18, 2015 Share Posted December 18, 2015 (edited) The gist of my problem was that I was getting 20 MBPS less than my "suppose to be" speed (1oo MBPS) Reverting back to the original NIC driver fixed it and I instantly got a full 100 MBPS instead of 70-80 MPBS (that's what I thought). I then found out that after a few restarts I'll see the "Updates were installed" message and even though my NIC driver stayed on the same version something was changed in my system and I, once again, got 20 MBPS less of internet speed. I have no idea what is causing this. Uninstalling the NIC driver from the device manager will Uninstall the driver and will Reinstall the same driver automatically and WILL fix the problem and I will get full speed again. After a few restarts the issue will return. I've gone through the NIC advanced settings, changing them one by one and found out that "Interrupt Moderation Rate" is the cause for the problem or at least a part of the problem. The setting was on Adaptive that gave me the dreadful 80 MBPS. Changing it to OFF kept my speed on 80MBPS but changing it to "Extreme" instantly bumped my internet connection to 100 MBPS. I have no idea why this is happening so any info on that would be great.

Shasoosh Posted December 27, 2015 Author Share Posted December 27, 2015 Ok, After a lot of digging I've found the main problem. One of the Windows updates causes this behavior: Adaptive is the default value after the LAN driver install which costs me 20 MBPS. No idea why adaptive causes this. This wasn't happening before.

tsupersonic Posted December 28, 2015 Share Posted December 28, 2015 (edited) Hmm very interesting. I'm using an Asrock Z87 motherboard with the Intel I217-V. I'll have to check this out when I go home. Nice find. What version of Windows is this, and do you know which update in particular? BTW, nice download speed, but what's up with your upload speed?!

Shasoosh Posted December 28, 2015 Author Share Posted December 28, 2015 Hey, I'm on Windows 10 Pro. I don't know what update caused this. I do know for sure that in the past Adaptive didn't caused this and gave me full bandwidth. Believe it or now, that's the maximum upload speed you can get here on Cables. Really sad actually. I tried contacting Intel with this, they told me to contact Gigabyte. I emailed Gigabyte with this video and they told me that they will forward it to Intel...

xendrome Posted December 28, 2015 Share Posted December 28, 2015 Make sure "energy efficient" is turned off under Power Management on the LAN adapter also. Link to comment Share on other sites More sharing options...
Pam14160 Posted December 28, 2015 Share Posted December 28, 2015 Just tested, and am very happy with the present speed 194.5 MBS. . . Link to comment Share on other sites More sharing options...
winrez Posted December 28, 2015 Share Posted December 28, 2015 1) Click on Settings 2) Update and Security 3) Highlight "Windows Update" and click Advanced Options 4) Click Choose How Updates Are Delivered 5) Toggle the switch to Off 6) Reboot You should have normal speeds again Link to comment Share on other sites More sharing options...

This was turned off 5 minutes after I installed Windows 10. Link to comment Share on other sites More sharing options...

Anyways, my I217-V Interrupt Moderation Rate was also set to Adaptive. I ran a speed test with this set to Adaptive, and got 37.22 Mbps down/6.30 Mbps up. With the Interrupt Moderation Rate set to Extreme, I re-ran the speedtest, and got 37.21 Mbps down/6.31 Mbps up. I'm on Windows 10/fast ring. I'm paying for 30 Mbps down/5 Mbps up - Time Warner. I have my desktop hooked up to my TP-Link Archer C7 gigabit router, which is hooked up to my Zoom 5341J cable modem. Link to comment Share on other sites More sharing options...
Shasoosh Posted December 28, 2015 Author Share Posted December 28, 2015 Have you updated your LAN drivers recently? Link to comment Share on other sites More sharing options...

The only drivers/firmware I update on a regular basis are the video card, and SSD. Other than that, I follow the "if it ain't broke, don't fix it" philosophy Link to comment Share on other sites More sharing options...
