Public bug reported: WiFi (WLAN) Module: Realtek RTL8723DE (came with my HP laptop). Ubuntu 20.04 is the first Ubuntu release to have the module working out of the box.
Network devices as output by 'inxi -N' Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet driver: r8169 Device-2: Realtek RTL8723DE 802.11b/g/n PCIe Adapter driver: rtw_pci Device-3: Realtek 802.11n WLAN Adapter type: USB driver: btusb The error 'rtw_pci 0000:0d:00.0: failed to send h2c command' is logged every time I use the module for internet access. The error is logged more frequently especially if I stream a video and other related tasks. The driver is stable but it may fail become unavailable unless a cold boot is performed. The attached log contains the error logged many times when I was streaming a video Today. According to https://askubuntu.com/questions/1217892/system-responds-with-failed-to- send-h2c-command-on-shutdown-what-does-that-me the error may be due to a firmware issue or the driver issue. The error does not occur if using the Realtek drivers obtained from Github in this link: https://github.com/lwfinger/rtw88 and the driver of the module is identified as rtw_8723de.
