OS support for M.2 2230-Intel WIFI

Borislav

I received my Ultra Starter Package several weeks ago. I tried to run wireless only system via the included WIFI card, but I'm unable to get it working. A few minutes after reboot the connection gets unstable and then the card goes offline with microcode errors in dmesg. I tried both ubilinux and Ubunto with latest kernels. Did anyone managed to get this working and if so on what OS/kernel version?
Thanks

Hi Bobsana
Can you please give us the card model/manufacturer?
Also please submit us the output of the sysinfo script as explained here:

https://up-community.org/wiki/Software#Requesting_support_for_Linux_OS

Please use ubilinux 4 to do the test.
Thanks

Hi Bobsana,

In reply to your question, I am using the supplied 'official' Wi-Fi card in my UP squared, (updated to BIOS 2.1) running the release version of Ubuntu 17.10 which recognised the card immediately, and sorted out the necessary drivers etc without any further input from me at all.

The connection has remained constant, and I have not experienced dropped connections.

Hopefully the advice given by Nicola in her post will assist you however.

I'm sorry for late reply, I had some other things on my head.

[edit] The card is the one I received as part of the "UP² Pentium Ultra Starter Package", I suppose it's M.2 2230-Intel WIFI 802.11ac+Bluetooth4.2

I'm running Ubilinux from external SATA hard disk (nothing on the emmc). Attached are two sysinfo dumps from two restarts:

sysinfo-after-hardware-reset:

At about 741 second in dmesg I get some errors and wifi connection stalls

[  742.032105] iwlwifi 0000:04:00.0: Microcode SW error detected.  Restarting 0x2000000.
[  742.040887] iwlwifi 0000:04:00.0: CSR values:
[  742.045781] iwlwifi 0000:04:00.0: (2nd byte of CSR_INT_COALESCING is CSR_INT_PERIODIC_REG)

sysinfo-emmc:

This does not happer every time but it's quite frequently (once every 3-4 reboots). I'm not sure if it's related to the wlan issue.

[    3.285385] mmc0: mmc_select_hs200 failed, error -84
[    3.285675] mmc0: error -84 whilst initialising MMC card
