Title:
The network adapter sometimes stops working until the next reboot
Status in linux package in Ubuntu:
Confirmed
Bug description:
Kubuntu 22.04.1 LTS. Honor MagicBook 15 BMH-WFQ9HN.
The network adapter may randomly disconnect. It is not possible to enable it
via the "ip link set ip" command, it gives the following error:
sudo ip link set wlp1s0 up
RTNETLINK answers: Cannot send after transport endpoint shutdown
Rebooting helps, but it's terribly inconvenient. Kubuntu Info Center gives me
the following information about the adapter:
01:00:0 Network controller: Qualcomm Atheros QCNFA765 (rev 01)
Subsystem: Foxconn International, Inc. Device e0ca
Flags: bus master, fast devsel, latency 0, IRQ 78, IOMMU group 7
Memory at d0000000 (64-bit, non-prefetchable) [size=2M]
Capabilities: [40] Power Managment version 3
Capabilities: [50] MSI: Enable+ Count 32/32 Maskable+ 64bit-
Capabilities: [70] Express Endpoint, MSI 00
Capabilities: [100] Advanced Error Reporting
Capabilities: [148] Secondary PCI Express
Capabilities: [158] Transaction Processing Hints
Capabilities: [1e4] Latency Tolerance Reporting
Capabilities: [1ec] L1 PM Substates
Kernel driver in use: ath11k_pci
Kernel modules: ath11k_pci
Driver was installed automatically when the system was installed
The adapter can disconnect itself only when connected to a 2.4 GHz Wi-Fi,
everything works stably with 5 GHz.
The solution from here
(https://bbs.archlinux.org/viewtopic.php?id=264268) didn't help
System logs will be attached automatically after using "ubuntu-bug
linux" command, I suppose..
