My Lenovo H415 desktop Internet connection is slow. Speedtest.net reports 60Mbps from the ISP to my laptop with ethernet wired connection to Netscape Nighthawk router. The laptop and our HP desktop report wifi transfers of 25-30 Mbps. The Lenovo on same wifi network reports about 6 Mbps transfers in and out. OS is Windows 10.
Where do I look for this machine's sluggish behavior?
Solved! Go to Solution.

I had a similar issue with my system, and restarting my WiFi router fixed the ridiculous slow connection that you are seeing, but it still was about 10 Mbps slower than normal since updating the the Creators Edition. I found a solution that worked for me, which started with downgrading the device Driver for my WiFi adapter, and then running the following commands to disable RSC, and changing the MTU value from the default of 1500 to 1400.
Note My WiFi card is a Realtek RTL8723BE Wireless LAN 802.11n PCI-E NIC, and I was able to downgrade the driver by using an older WiFi driver stored in the C:\Drivers folder, which contained the installers for the older driver versions.
Windows 10 Creators Edtion WiFi speed fix
Note: Mine was just called Wi-Fi, but yours may be different
Command Examples assuming your adapter is also listed as Wi-Fi
netsh interface ipv4 set subinterface "Wi-Fi" mtu=1400 store=persistent
Disable-NetAdapterRsc -Name Wi-Fi
Note: You can restore the defaults by typing the following.
netsh interface ipv4 set subinterface "Wireless Network Connection" mtu=1500 store=persistent
Enable-NetAdapterRsc -Name Wireless Network Connection

Wow! Thanks for the immediate response. I'll think about that for a while. I have the same problem posted to the Netscape router forum since the router setup page also reports 63Mbps available from the ISP while running wirelessly.

Yeah, I had no problems with the router, and all other devices not on windows 10 creators edition had no problem with speed either.
I should have mentioned also that Microsoft considers slow WiFi problems in Windows 10 Creators Edition an emerging issue, and is the source of the MTU & RSC workarounds.
I expect that there will be a Windows Update at some point that will address it too, but when is unknown.

I replaced the Premiertek Wireless Adapter I have been using with a new Netgear N600 Dual Band Wireless N Adapter and instantly achieved 66Mbps download and 6Mbps upload.
Thanks to all for the patience of reading my situation and providing comment.
