Wifi on Lenovo 320S-13IKB is terribly slow

Hello,

 

yesterday i received a brand new Lenovo 320S-13IKB 81AK0036GE. Directly when starting the device, i noticed that web pages load really slow. Since i have a 100MBit internet connection at home, i was a bit worried.

 

So i run some tests with the 320s and my Thinkpad T440s. Both on the same wifi network.

 

* Downloading a file (Ubuntu iso image) from as fast server located in my country (Germany)

- Lenovo 320S: Around 150-200 KB/s

- Thinkpad T440s: 3.0-4.5 MB/s

 

* Executing a DSL Speedtest: speedtest.net/de

- Lenovo 320S: 1.8 MBit/s down, 5Mbit/s up

- Thinkpad T440s: 41 Mbit/s down, 5 Mbit/s up

 

I am really confused by the fact that the upload on the 320S is faster than the download.

I installed the newest wifi drivers: https://pcsupport.lenovo.com/de/de/products/laptops-and-netbooks/300-series/320s-13ikb/81ak/download...

I even booted Ubuntu Linux from a USB stick: The wifi was also slow using Ubuntu...

 

Do you have any idea what this could be? I am very disappointed because Lenovo notebooks always worked well for me, and this one is brand new...

 

Best regards,

Alex

Bump.

 

Please help me with this problem. The laptop is brand new and i have to return it if i can't solve the problem.

After doing some research i believe the Atheros QCA9377 driver is the reason, that on some networks that use WMM, the wifi is slow. I tried various driver versions but the problem persists.

If i create a hotspot on my Samsung Galaxy S7 and connect with the 320s, i get around 30MBit/s speed. Please understand that changing the settings on my router is not a solution, because i also want to use the device on wifi networks where i cannot change the settings.

 

I also contacted your support via email contact form but how am i supposed to describe a problem like this in 200 characters?
