Title:
WiFi Realtek RTL8852BE (rtw89_8852bte) fails to find networks after
resuming from suspend on HP laptop
Status in linux-hwe-6.14 package in Ubuntu:
Triaged
Bug description:
Hello,
My Wi-Fi adapter stops working after the system resumes from suspend
(lid close/open). The hardware is a Realtek RTL8852BE on a new HP
laptop running Ubuntu 24.04.
**Steps to reproduce the problem:**
1. Boot the laptop normally. Wi-Fi works perfectly.
2. Close the laptop lid to trigger suspend mode.
3. Wait a few seconds and open the lid to resume.
**What happens (Actual Result):**
The Wi-Fi interface (wlo1) is visible, but it cannot detect any wireless
networks. It is impossible to connect.
**What should happen (Expected Result):**
The Wi-Fi should resume its function correctly and show all available
networks, reconnecting automatically.
