[Solved] Internet is slow on windows

I'm facing a weird issue where my internet speeds on Windows appear to hover around 3Mbps while on the same machine, everything works fine on my dual booted Ubuntu installation.

A hardware / router / placement problem can be ruled out, since the everything is functioning completely fine in the other dual booted operating system.

Solution:

I was able to get the internet working fast again by doing a Windows 10 in place upgrade. (Reinstalling windows while keeping all the files and programs intact.)

Links :

  1. How to Do a Repair Install of Windows 10 with an In-place Upgrade
  2. Windows 10 build 14379 ISO images (You can upgrade using the same or a higher build version).

Device:

  • Using Windows 10 Pro Insider Preview
  • Build 14379.rs1-release.160627-1607
  • I'm using an Edimax N150 (EW-7811UN) USB WiFi adapter. - The drivers are installed.
  • Netgear N300 Wi-Fi DOCSIS 3.0 Cable Modem Router (C3000)

Steps I have taken:

  • I made sure that there were no other processes running in the background which were using the Internet. (Windows is not downloading updates in the background)

  • Tried disconnecting/reconnecting the device. (multiple times, in multiple configurations)

  • Tried uninstalling, then re-installing drivers. (multiple times, in multiple configurations)

  • Tried restarting Windows. (multiple times, in multiple configurations)

  • Tried uninstalling device drivers to run with Windows default drivers. (same issue)

  • Disabled "Updates from more than one place". (The new torrent like update mechanism.)

  • Tested Pings to my DNS.

  • Tried switching to Google DNS ¯\_(ツ)_/¯

  • Turned off Location in Activity Center.

  • Changing the wireless mode - helped a little bit! read below. Speeds are now up to 6.x Mbps.

  • Tried running ipconfig /release followed by ipconfig /renew.

  • Tried running ipconfig /flushdns followed by ipconfig /registerdns.

  • Tried running the Windows Network Diagnostics tool.

  • Tried disabling IPV6 - speeds actually dropped down to 4.x Mbps, re-enabling increased it back to 6.x Mbps.

  • Ran netsh winsock reset, netsh int ipv4 reset, netsh int ipv6 reset - rebooted. No luck.

  • Ran netsh int ip reset resettcpip.txt.

  • Disabled/Enabled Windows Firewall.

  • Checked the hosts file for potential issues.

  • Disabled bandwidth limit.

  • Disabled power management on the device

  • Tried reinstalling network devices using netcfg –d.

  • Tried Enabling/Disabling Adaptivity

  • [Solution] : Windows 10 in place upgrade. (Read here)

Changing the wireless mode:

Interestingly, When the wireless mode is set to IEEE 802.11b/g/n, speeds max out below 4 Mbps, but when I set it to IEEE 802.11b/g, I gain a >2 Mbps boost. I'll take it!

Wireless Mode Speed

Values remain around the same when set to IEEE 802.11b
