The thread I am referring to is the one with the same subject as this email. >From what I can understand, Kalle Valo and Wen Gong are trying to reproduce the problem, but they had difficulties retrieving the correct hardware. Since I can reproduce the issue with a different router, probably easier to retrieve, I thought I would dump the information here. I have the exact same laptop as Nicola Mori, an XPS 15 9570 and I am running Fedora 31 (kernel 5.6.8). The wifi card is reported as: 3b:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32) Subsystem: Bigfoot Networks, Inc. Device 1535 Kernel driver in use: ath10k_pci Kernel modules: ath10k_pci I have tried switching in and out a couple of firmwares with API 6 and I can reproduce the problem with all the versions I tested: WLAN.RM.4.4.1-00128-QCARMSWPZ-1 WLAN.RM.4.4.1-00132-QCARMSWP-1 WLAN.RM.4.4.1-00140-QCARMSWPZ-1 (default one on Fedora 31) WLAN.RM.4.4.1-00151-QCARMSWPZ-2 Regarding the router, it is a Linksys E2500 v3, with firmware 3.0.05 (latest). I use both 2.4 GHz and 5 GHz wireless, with the same SSID. As for the information regarding the wifi settings: - Channel: Auto (DFS) - Channel width: Auto (20 MHz or 40 MHz) - Encryption: WPA2-Personal Regarding reproduction, I would like to add that the issue happens quite rarely. Using my laptop the whole day at max 4 meters from the router, it happens only once or twice a day. In addition, when I am unable to start new connections, and applications like Zoom are still running perfectly, I can work around the issue not only by disabling and re-enabling the wifi, but also pinging my laptop from another device in the network. To clarify, when I am experiencing the issue, if I ping my laptop from my phone, it starts working correctly again. I am not sure if this is related, but it happens often, but not exclusively, when I am using Zoom for videoconferencing. However, I cannot confirm that it is the cause. Feel free to contact me for any additional information you may need.
