Recently re-installed Lubuntu 19.04 on a new SSD because the old one failed. However, with the updated versions of Lubuntu I get extremely slow WiFi speeds. This was not a problem with the previous installation of 17.10. After some research, I found on 18:04 several posts to Intel Wi-Fi adapters. However, my lspci-sourced chipset is a Ralink RT5392 chipset, so solutions to Intel adapters did not help. Checking the normal Internet speed on other computers in the house is only possible on Lubuntu computers. Any suggestions?
EDIT: and now it seems unreliable to show the networks as available, sometimes the network icon disappears and needs to be restarted etc. Strange, because it's a fresh install a few hours ago with a new image from today.
