Hi You-Sheng Yang, this problem happen on my computer, Dell G7-7588, and @Patola try to help me. So I tried do this command sudo apport-collect 1884100 but after open the web page and click ok my Ubuntu said: "You are not the reporter or subscriber of this problem report, or the report is a duplicate or already closed. Please Create a New Repost Using "apport-bug"
So why can I do ? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1884100 Title: Qualcomm Atheros QCA6174 802.11ac fails in linux-firmware 1.187 Status in linux-firmware package in Ubuntu: Incomplete Bug description: This bug is done for a friend. I do talk to him occasionally and he sends me data. As he's a newbie, he doesn't know how to create a proper bug report. Basically, his notebook has the Qualcomm Atheros QCA6174 802.11ac wireless network adapter (rev 32). He had Ubuntu 19.10 and it worked. He updated to 20.04 and it stopped working. He installed 20.04 from scratch and it did not work. 20.04's linux-firmware is 1.187. This version does not work for Qualcomm Atheros QCA6174 802.11ac. I asked him to download 19.10's linux-firmware package from the ubuntu repositories, which is at 1.183. After he installed, apt-marked hold the package so that it would not be upgrade, and rebooted, his wifi worked. I saw the other bug reports regarding this adapter but they are old, the newer one has expired and it seems to be related to the unsigned kernel.
