Wireless connection becomes temporarily faster after restarting device

I'm using systemd-networkd with iwd to manage my connection.
This is the relevant part of lspci -v:

04:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter (rev 01)
        Subsystem: Lenovo Device 0179
        Flags: bus master, fast devsel, latency 0, IRQ 34
        I/O ports at c000 [size=256]
        Memory at f7100000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: [40] Power Management version 3
        Capabilities: [50] MSI: Enable+ Count=1/1 Maskable- 64bit+
        Capabilities: [70] Express Endpoint, MSI 00
        Capabilities: [100] Advanced Error Reporting
        Capabilities: [140] Device Serial Number 00-e0-4c-ff-fe-81-91-01
        Capabilities: [150] Latency Tolerance Reporting
        Kernel driver in use: rtl8188ee
        Kernel modules: rtl8188ee

I think my driver is installed correctly.

The problem is that after some time, my download speed becomes slow.
Checking tools like speedtest-cli or YouTube's "stats for nerds" reveals that my download speed drops to around 0.2-0.5 Mbyte/s.
Every time that happens, restarting the device like this:

❯ iwctl
NetworkConfigurationEnabled: disabled
StateDirectory: /var/lib/iwd
Version: 2.3
[iwd]# device wlan0 set-property Powered off
[iwd]# device wlan0 set-property Powered on

Always fixes the issue without fail. After doing this, my download speed goes back to around 5-8 Mbyte/s .

Can anyone provide any hints on how to diagnose this issue?

Re: Wireless connection becomes temporarily faster after restarting device

I've fixed the issue by switching from iwd to wpa_supplicant.
