Slow WiFi on T440p after 19.1.0 version update

Hello,

 

I'm noticing a lot slower internet connection after the drivers were updated to version 19.1.0 via Lenovo's System Update (Intel Dual Band Wireless-N 7260, driver version 18.33.3.2).

 

When on cable, everything works perfectly, but when on WiFi, webpages and YouTube work slower. Especially YouTube  - it should load videos instantly and in HD (my internet connection is 30/5 Mbps), but there is a big lag, and 4K videos won't work at all. A lot of times YT automaticaly switches the video to 360p.

 

I did extensive checks and there are no major disturbances on the WiFi signal. Also, YouTube works flawlessly (via WiFi) on my Lenovo ThinkPad E430 (2013) and MacBook Pro (2011), plus on the mobile devices.

 

Could you please check if you are noticing the same on T440p? Thanks!

 

My system config:

- Windows 10 Pro, version 10.0.14393 Build 14393.

- 16 GB RAM

- 2x SSD (Samsung 840 and 850 EVO), BitLocker and HW encryption enabled

- Intel Dual Band Wireless-N 7260

- All Windows and Lenovo updates installed

It could be a bad driver update, so I would go back to the previous version following the steps below.

 

  • Right Click on Start
  • Select Device Manager
  • Select Network Adapters
  • Right Click on your WiFi Adapter and select "Update Driver Software"
  • Select "Browse my computer for driver Software"
  • Select "Let me select from a list of device drivers on my computer"
  • Select a previous version of the driver for your WiFi card and click next to install it
  • Test your WiFi Connection

Note:  You may need to reboot.

 

Good Luck,

Thanks! That seemed to work. I really didn't know that you can do that. Smiley Happy
