Ubuntu PC is not pingable. Web services are not available over intranet. Mediatek driver issue?

Ubuntu Version:
25.04 Plucky

Desktop Environment (if applicable):
GNOME

Problem Description:
My PC is not visible in my router’s routing table and is not pingable after several minutes of connection to WIFI. Trying to connect to the PC yields a NSURLErrorDomain message on Firefox and “Server not reachable” on Safari. Web services are not reachable over the internet including: *Arr suite, Jellyfin, Transmission web client, SSH. Restarting NetworkManager service fixes this problem temporarily. The connectivity problems seem to start after the following error appears in the logs: bgscan simple: Failed to enable signal strength monitoring. I am still able to access the internet through the WIFI when this occurs.

Relevant System Information:

CPU: AMD Ryzen 9900X
MB: Asrock X870E Nova Wifi

Network controller [0280]: MEDIATEK Corp. Device [14c3:0717]
Subsystem: MEDIATEK Corp. Device [14c3:0717]
Kernel driver in use: mt7925e
Kernel modules: mt7925e

What I’ve Tried:
Restarting the NetworkManager service → fixes the issue temporarily.
Forgetting the WFI network and reconnecting → fixes temporarily.
Rebooting the PC → fixes temporarily
Disabling or re-enabling VPN → No effect
Running netstat and ifconfig revealed no issues that I could discern.

########## wireless info END ############

What drops off the network is the MediaTek mt7925e Wi-Fi chip, not the router.
After a few minutes NetworkManager puts the card into power-save; the current
driver/firmware combo (kernel 6.14) sometimes fails to wake up again, so it
stops answering ARP requests. Out-bound traffic still works, but nothing on
the LAN can find the machine until you bounce NetworkManager.

Quick workaround – turn Wi-Fi power-save off

create a global override
sudo mkdir -p /etc/NetworkManager/conf.d
echo -e "[device]\nwifi.powersave = 2" | \
     sudo tee /etc/NetworkManager/conf.d/99-no-wifi-powersave.conf

 reload NM (no reboot needed)
sudo systemctl restart NetworkManager

wifi.powersave = 2 means “never put the radio into PS mode”.
The card now keeps replying to ARP and stays visible in the router table.

If you prefer to change only one network:

nmcli connection modify Big_Chungus 802-11-wireless.powersave 2
nmcli connection up Big_Chungus

Permanent fix – newer firmware / kernel

Kernel 6.15 includes several mt7925e fixes, and the corresponding firmware
blobs stop the “bgscan simple: Failed to enable signal strength monitoring”
error. When it reaches plucky-updates you’ll get it automatically:

sudo apt update && sudo apt full-upgrade

(or install the oem-6.15 stack from proposed if you’re happy to test).

Summary

The connectivity drop is a mt7925e power-save bug.
Disabling Wi-Fi power-save with the NM override stops the disappearances
right away.
Keep your system updated; when the 6.15 kernel + new firmware land you can
delete the override and re-enable power-save if you want.

I performed the quick workaraound method as written. This method stopped the bgscan simple errors from occurring, but did not solve the overall problem of the web services not being reachable over the intranet until restarting the NetworkManager. Any other suggestions or solutions for why this might be happening?

bgscan simple was only half the story.
Each time the mt7925e chip drops and
re-authenticates NetworkManager also gives it a new random MAC
address (default privacy-randomisation).
The router’s ARP table still maps
your old MAC to 10.0.0.23, so every packet destined for the PC is
sent to the wrong layer-2 address until the table ages out or
NetworkManager is restarted.

Outbound traffic works (it uses the fresh MAC), but anything that tries
to reach the machine by IP fails - the *Arr web UIs, Jellyfin, SSH, your
browser tests, the “not pingable” symptom, the device vanishing from the
router list.

Fix: keep the hardware MAC for that Wi-Fi profile

nmcli connection modify Big_Chungus \
        wifi.cloned-mac-address permanent \
        wifi.mac-address-randomization 0
nmcli connection up Big_Chungus

or in the GUI
Settings - Wi-Fi - Big_Chungus - Privacy - “Device MAC”.

permanent/0 tells NM to use the card’s real address every time, so the
router’s ARP entry never goes stale. (You can leave the global
wifi.powersave = 2 override in place until 6.15 arrives.)

What to expect

No more MAC changes - IP - MAC mapping in the router stays valid.
Services (*Arr, Jellyfin, SSH, etc.) remain reachable for hours /
days without restarting NetworkManager.
When kernel 6.15 + new mt7925e firmware lands you can test re-enabling
Wi-Fi power-save; the fixed driver keeps the link up and the stable MAC
keeps inbound connections working.

If the machine still disappears after that, flush the router’s ARP cache
(management UI or power-cycle) once to clear any old mappings; it should
stay visible afterwards.

I don’t know anything about your specific situation but I have six laptops on the internet full time. They are all visible on my samba local network but are invisible to the www. In other words no outward open ports. Back in the old days (last millennium} I used a static Ip through my domain. As time evolved static Ip’s became very expensive due to the developing lack of IP numbers. There was commercial site that handled this problem but I can’t remember what they were at the time (early onset CR?).

I’m sorry to report that disabling MAC address randomization had no effect on the connectivity issues, including after restarting the pc and router.

Something else I tried: I booted a live USB stick with the most recent version of Linux Mint, installed the *Arr suite and Jellyfin and had no issues. Im wondering if maybe I should do a clean install with Ubuntu 24 LTS to fix this issue?
