A new Flyspray task has been opened. Details are below.
User who did this - Leon Möller (jkhsjdhjs)
Attached to Project - OpenWrt/LEDE Project
Summary - DFS channel change causes 5GHz WiFi to fail
Task Type - Bug Report
Category - Kernel
Status - Unconfirmed
Assigned To -
Operating System - All
Severity - Low
Priority - Very Low
Reported Version - openwrt-19.07
Due in Version - Undecided
Due Date - Undecided
Details - My TP-Link AC1750 Archer C7 v5 just detected another WiFi on the same 5GHz channel. Thus it tried to switch to a different channel, which apparently succeeded. Afterwards the kernel experienced a bug causing the 5GHz WiFi to fail indefinitely.
I've attached a list of installed packages and the relevant syslog:
Lines 1 - 7 show the change to a different channel
Lines 8 - 10 show a device disconnecting and reconnecting (probably because of the channel switch)
Lines 11 - 82 are SWBA overrun warnings
Lines 90 - 190 are kernel traces
Lines 255 - 261 show a device connecting to the 2.4GHz WiFi, because the 5GHz is no longer available
Lines 271 - 278 show other devices being disassociated as they are also unable to connect again
One or more files have been attached.
