A new Flyspray task has been opened. Details are below.
User who did this - Alfred Reichenberger (Alfredoredo)
Attached to Project - OpenWrt/LEDE Project
Summary - TP-Link RE450 v3: QCA9880 (5 GHz-Wifi) is only detected sporadically
Task Type - Bug Report
Category - Kernel
Status - Unconfirmed
Assigned To -
Operating System - All
Severity - Medium
Priority - Very Low
Reported Version - Trunk
Due in Version - Undecided
Due Date - Undecided
Details - - Device: TP-Link RE450 v3
- OpenWRT-version: OpenWRT SNAPSHOT r14198-da98603597 (snapshot from 8/19/2020)
- Installed packages: Just the base install + LuCI
- Steps to reproduce:
* Install OpenWRT via stock firmware web interface
* 'iw list' shows 2 physical interfaces: 2.4 GHz (phy1) and 5 GHz (phy0)
* Reboot
* 'iw list' now only shows the 2.4 GHz-wifi
* 5 GHz-wifi is only redetected after power-cycling, simple reboot doesn't work
- Logs:
* dmesg with both interfaces:
