I am using Ubuntu 18.04 on a laptop. I connected to a new WiFi network and am experiencing very slow internet. The same network on both a mobile phone and with the same laptop booted on Windows works perfectly fine.

In particular, if I run a speed test through Chrome/Firefox, I get a download speed of around 70 Mbps but an upload speed that starts around 3-5 Mbps and immediately drops to 0 Mbps.

The internet is fine if I switch to another WiFi network such as tethering through a mobile phone, which has always worked fine. Switching browsers does not help. Interestingly, running speedtest-cli gives both the download speed and upload speeds at ≈ 70 Mbps.

Please let me know what other information may help. Thanks!

I had the same issue when updating from ubuntu 16.04 to ubuntu 18.04, I did the following to solve the issue : 

sudo add-apt-repository ppa:teejee2008/ppa
sudo apt update
sudo apt install ukuu

ukuu is for ubuntu kernel update utility After that you can run ukuu with a GUI to install the last stable kernel version
