[help] GK3 J4125 ACEPC suddenly no wifi, no lan hardware is detected but Bluetooth is OK.

[wazoo]

Hello
I have an ACEPC GK3 with J4125 processor running for more than 1 year with HomeAssistant and others in containers under Armbian OS.
Yesterday, it seems that something happened and suddenly the LAN activity LEDs no longer light up and neither does the WLAN.
The LAN cable is OK. When connecting HDMI monitor the miniPC boots normally, except that it doesn't detect LAN and WIFI hardware anymore.
All the hardware seems to work OK, but I have lost connectivity.
The strange thing is that it detects bluetooth hardware which I think is the same chipset/module as WIFI.

I've tried running other liveUSB distro, like Sergei Strelec's distro and even reinstalling linux on another SSD, but it doesn't wake up LAN or WIFI.

It's a rare case. Any idea what could have happened ?
Is it possible that by some software code you can force a hardware lock to sleep / low power mode and it will not be detected or woken up again ?

I am trying to find information about the pinout of the RTL8111BN IC (48pin) to check if there is a power supply problem.
I have checked nearby capacitors and I see 3.3v. So I think it could be a software lockout. But even with a new OS I can't wake it up.

I would appreciate your help.

It is recommended that you try uninstalling recent Windows updates or rolling back the system to a previous stable version.

The same thing happened to me. I tried reinstalling, reverting to the previous version - nothing helped... the strange thing is that it happened at the same time as yours... maybe from some update?
Did you find a solution?

[tmpmnit2370]

nessuna soluzione li sto provando tutte,ora sto riinstallando da cloud vediamo se va se no metto linux

[tmpmnit2370]

reinstallato windows 10 che viene dato qua ma non vengono rivelate le schede si puo' sapere che schede usa magari metterli manuali,neanche con linus funziona in live la scheda wifi va ma installato niente,puo' essere dal bios?

[tmpmnit2370]

ho reinstallato il suo sistema iniziale ma niente continua a non poter usare e vedere sia lan che wifi sono scomparse del tutto,solo con un adattatore ethernet esterno riesco ad avere la rete , avvevo messo linux mint con la live funzionava almeno il wifi pensavo ora funziona,invece no installato continua a non vedere nessuna scheda di rete.

Are you able to see anything in the BIOS? Does the operating system see the device is there, even if it doesn't know how to use it?

non ho guardato nel bios ma le schede di rete sono scomparse ,ho messo il suo hard disk originale e non li trova neanche li,avevo messo una distro linus in live vedeva solo il wifi installandolo nessuna scheda

Please check for it in the BIOS. It's difficult to tell if the operating system doesn't know how to use the card, or if the computer can't detect it. Linux has so many distros, and it's possible it needs drivers that didn't come with it.
