Below is an excerpt from a near–clean Ubuntu 25.04 install that lost network connectivity midday. The machine remained in Wi-Fi range after reboot (see log excerpt below), and - being constantly connected to power - issues related to wake/sleep cycles can be largely ruled out. The secondary USB-C hub’s wired connection remained stable, as expected. All of the recurring “Activation of network connection failed” pop-ups referred to the wireless interface attempting - and failing - to reconnect.

Description: Firmware for Linux kernel drivers
This package provides firmware used by Linux kernel drivers.
I’ve just updated Fedora 42 to kernel 6.14.4-300.fc42.x86_64.
The good news is the connection now seems to be stable - I’m no longer getting any more disconnections.
The bad news is it’s still slow. Never more than 90Mbps on any speed test, with devices right next to it getting far higher speeds (and Windows on the same device getting very high speeds). This is whilst connected to a WiFi 7 AP.
Gnome network settings does show a 6GHz connection sometimes when I’ve just connected, however quickly switches to the 5GHz band. Not the end of the world - but 90Mbps is slow even for 5GHz! WiFi 6 devices in the same location get around 500Mbps.
I’ve also tried dracut --force as suggested, rebooting, restarting WiFi again… nada.
I have the same operating system and firmware as Daniel, but my problem is somehow different.
My laptop connects just fine upon boot and it will stay connected throughout the day, but it will stop working outright when I decide do switch networks. Both connecting to a new network as well as reconnecting to the old one fails. To get WiFi working I have to turn it off and on again.
Matt, any update on Ubuntu for the Ryzen AI? I’m still seeing networking issues in Bazzite (slow speeds), and it seems that the MAC address issue recurs (I had to reset it at least once)…
@thedaniel I’ve been using Linux for 17 years and to this day I’ve never known that there was a way to use the newest stuffs. Is there an easy walkthrough for this?
The MT7925 driver in 6.14.3 and 4 has a multicast problem. This also means no ipv6 address is assigned because its not receiving the router advertisements.
To hazard a guess, MAC randomization with the authentication/association phases. Generally in situations like this, at least in GNOME. This example I provided is specific to Mesh in this case below. BSSID is also fine if married to a single WAP device.
Network manager for that connection.
Identity, Stable per SSID or stable.
Save, reboot or restart network manager.
Also just edit /etc/NetworkManager/system-connections/NetworkConnectionName.nmconnection
Emphasis on adding cloned-mac-address=stable
(This can be don in GNOME via GUI)
Close, reboot or restart Network Manager service.
Being clear, you should be on 6.14.3+ for a happy place in terms of power management.
This is addressing a “possible” MAC address randomization challenge with a workaround if you find you are absolutely on 6.14.3+ and still see drop offs.
This is not a fix, this is a troubleshooting tool to determine possible cause. So a bug report can be filed as needed.
thanks for your reply. unfortunately changing to cloned-mac-address=stable didnt solve the issue - when switching to the 5GhZ BSSID, my connection drops dead.
Just a friendly reminder (looking at Ubuntu users specifically), if you are on older than 6.14.3, you will see wifi drop off. Thank you.
Please be sure to include:
Distro and version (For rolling, date of last update):

WAP type and model: (Especially Mesh configurations and when your last WAP firmware update was)
@Matt_Hartley I replaced the Mediatek modem in my FW13 (Ryzen 7 AI) with a refurb AX210 and all networking issues seem to be resolved. Only been testing a day but zero connection drops on both Ubuntu and Bazzite so far…
I just got the new F13 AI 300 series, installed latest Fedora, WiFi works. Ran dnf upgrade, rebooted and WiFi does not work any longer. Any tips to make this work?
