Posted (edited) · ultimaker UM3 wifi dead ? (hardware not even registered in dmesg)

Hi there. My UM3 suddenly talks no wifi at all.

Firmware is 5.3.0

It will also hang on indefinitely while trying in vain to create a hotspot.

Given the kernel logs, it looks like  `wlan0` hardware is no more showing up as yesterday.
Note that I attached two logs, one from yesterday that show `connmand` correctly sees and handles `wlan0` while the other one (NO-WLAN) show no wifi hardware at all.

(please ignore the message "no space left on device" at the very end, it was just the USB key I used to export the log)

Is my wifi dead ? That would be a pity esp. as I cannot use eth0, so I have to go back like I was in 2012 with an SD card...
What can I do ?

    Thanks for finding this post !  I somehow feels as being a noob since I hacked printers for a full decade. Actually I specifically bought the UM3 with the promise I would never open it, but, well, I have a good reason now 😝
    Will tell in a few days tho, I am far from it right now. Thanks again for the pointer, looks promising 🤞

    Back on the printer. Sadly, no, mine is firmly connected, with its screw to hold it in place. I obviously tried to disconnect and reconnect it without improvement.

    I am now looking for the board pinout (no silscreen), because I could try to find another wifi card.

    I would probably not even look for the official one since whatever comes from Ultimaker is outrageously expensive, and it does not prove reliable in my case. No word either from the official support as shown here.

    To the least, I am pretty disappointed 😢

    Oh I found some replacement : 160€ ! This is utterly ridiculous.
    Or $110 at some third party's while the Olimex board is $330, this can't be serious 😕

    For the record I tried some wifi dongle, in hope linux would see it. Sadly no (one of the logs below).
    I can't keep on trying, what a pain.

    Sadly, these wifi modules do sometimes break down. More info in my post: 

     

    You already tried other WiFi modules. I didn't check, but be aware that the Linux version in the UM3 printer is Debian Jessie, i.e. from 2015. Look for older WiFi models.

    Other paths to try:
    - Find another WiFi usb-module with the same chip (Atheros AR9271), costs about $19. The internal Olimex board has a spare USB port, except that the connector is a different type. Try the external USB connector first for testing.

    - Add an external WiFi access point on the LAN cable
