Actually, not an upgrade but a downgrade seems to have solved my problem. I have replaced the firmware file /lib/firmware/ath10k/QCA6174/hw3.0/firmware-6.bin with firmware-6.bin_WLAN.RM.4.4.1-00065-QCARMSWP-1 (which is what Ubuntu 17.10 might have had) and I have not had a single outage after a whole day. Before the change, the outages were very frequent.
So, it seems that the newer firmware files does not play nicely with my WiFi. Hopefully, this could help to rectify the problem on Ubuntu 18.04 with the new driver versions. Please let me know if I can provide further information to help for the diagnosis. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1743279 Title: QCA6174 stops working on newer kernels after second group rekeying To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1743279/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
