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!
