Description

A user has reported that their Wireless adapter no longer works in Tails 4.3. It did work in Tails 4.2.

It would seem that the Wifi device appears in network manager, but it can’t detect any networks. The user can connect an external ALFA card and successfully connect to a network.

The user tried disabling MAC spoofing, that didn’t help.

This is the device information.

I see this sort of errors in the Journal when the iwlwifi driver is used:

kernel: btintel: Unknown symbol hci_cmd_sync (err -2)
kernel: btintel: Unknown symbol bt_info (err -2)
kernel: btintel: Unknown symbol bt_to_errno (err -2)
kernel: btintel: Unknown symbol bt_err (err -2)
kernel: btintel: Unknown symbol __hci_cmd_sync (err -2)

On the same system, the r8169 Ethernet adapter exposes other “Unknown symbol” errors, which are very similar to those I see on the screenshot from Bug #17388.

I’m wondering if the problems I see with btintel and r8169 affect the Intel Wi-Fi adapter: I’ve tentatively classified those “Unknown symbol” errors as fallout of the workaround introduced in Tails 4.1.1, but according to this report, the problem reported here was not present in Tails 4.2 (now, bug reporters, like all human beings, sometimes make mistakes).

Anyway, the driver cries out loud due to a firmware problem:

Feb 21 23:37:14 amnesia kernel: iwlwifi 0000:00:14.3: Firmware not running - cannot dump error

So this could also be a firmware bug introduced by an upgrade.

Next steps:

  • check if we upgraded this firmware between 4.2 and 4.3
  • search the web for similar errors

The user has written to us saying that Tails 4.4 has resolved the issue.

  • Status changed from New to Resolved

Great, closing as resolved then!

numbat, don’t hesitate closing such issues yourself next time, when you learn that a problem you reported is not there anymore :)
