Description

### Kernel

7.1.3-1-cachyos, 7.1.3-1-cachyos-bore

### Desktop Environment / Window Manager

KDE Plasma

### CPU

AMD Ryzen 9 7950X3D

### GPU / Driver

AMD RX 7900 XTX

### Description

After a while the WiFi connection stops working. Pinging the router the PC is connected to doesn't work, there is no answer. After a while Plasma reports that the network isn't connected to the internet.

After some time, round about 5 minutes the connection reestablishes, other than that turning the WiFi off and on again also works.

The bug does NOT appear on the 6.18.38-1-cachyos-lts kernel, it also didn't appear on the 7.0 kernel before updating to 7.1

### Steps to Reproduce

1. start the system
2. use the internet and/or just wait

### Expected Behavior

The network connection should keep working

### Actual Behavior

The network connection stops working, packages can't be send or received

Research direction

Start by reviewing the linked log and comparing the failing 7.1.3-1-cachyos kernels with the working 6.18.38-1-cachyos-lts kernel and the earlier 7.0 kernel. Reproduce the WiFi timeout using the listed steps, then identify the kernel regression and verify that the connection remains usable without toggling WiFi.
