Tentando solucionar esse erro que pertence ao microcódigo, meu cartão de lspci mostra,

Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34)

system.log mostra,

iwlwifi: Detected Intel(R) Centrino(R) Advanced-N 6205 AGN, REV=0xB0

Quando eu corro modinfo , eu recebo, (um monte de coisas cortadas)

description:    Intel(R) Wireless WiFi driver for Linux
## lots of stuff...
firmware:       iwlwifi-6000g2b-6.ucode
firmware:       iwlwifi-6000g2a-6.ucode
firmware:       iwlwifi-6050-5.ucode
firmware:       iwlwifi-6000-6.ucode
## lots of stuff...
## NO iwlwifi-6205-#.ucode
srcversion:     6BA065AF04F0DFDB8D91DBF

Mas nenhuma delas mostra 6205. Qual .ucode é system.log referindo-se a quando diz,

iwlwifi: loaded firmware version 18.168.6.1 op_mode iwldvm

Há dois que eu poderia assumir,

firmware:       iwlwifi-6050-5.ucode
firmware:       iwlwifi-6000-6.ucode

Mas existe maneira de saber com certeza?

Esta resposta é estúpida, faça isso em seu lugar.

Percorrendo a fonte

Abaixo do buraco do coelho. A única maneira que eu poderia descobrir com certeza era grep a árvore fonte,

cd /tmp
apt source linux-modules-$(uname -r)

Depois fui buscar Advanced-N 6205 AGN ,

rgrep -l 'Advanced-N 6205 AGN' ./linux-4.15.0/
./linux-4.15.0/drivers/net/wireless/intel/iwlwifi/cfg/6000.c

E eu verifiquei o 6000.c que tem uma estrutura,

const struct iwl_cfg iwl6005_2agn_cfg = {
  .name = "Intel(R) Centrino(R) Advanced-N 6205 AGN"
  IWL_DEVICE_6005,
  .ht_params = &iwl6000_ht_params,
};

Pesquisando IWL_DEVICE_6005 , vejo que é um pré-processador definido para

#define IWL_DEVICE_6005           \
  .fw_name_pre = IWL6005_FW_PRE,        \
  .ucode_api_max = IWL6000G2_UCODE_API_MAX,   \
  .ucode_api_min = IWL6000G2_UCODE_API_MIN,   \
  .device_family = IWL_DEVICE_FAMILY_6005,    \
  .max_inst_size = IWL60_RTC_INST_SIZE,     \
  .max_data_size = IWL60_RTC_DATA_SIZE,     \
  .nvm_ver = EEPROM_6005_EEPROM_VERSION,    \
  .nvm_calib_ver = EEPROM_6005_TX_POWER_VERSION,  \
  .base_params = &iwl6000_g2_base_params,     \
  .eeprom_params = &iwl6000_eeprom_params,    \
  .led_mode = IWL_LED_RF_STATE,       \
  .max_ht_ampdu_exponent = IEEE80211_HT_MAX_AMPDU_64K

Qual o nome do firmware ( fw_name_pre ) é IWL6005_FW_PRE is

#define IWL6005_FW_PRE "iwlwifi-6000g2a-"

Então, eu acho que a resposta correta para essa pergunta é

iwlwifi-6000g2a-6.ucode

E a versão é

#define EEPROM_6005_EEPROM_VERSION  (0x709)

Embora eu sinta que o dmesg log é a melhor resposta para rastrear o carregamento de um arquivo de firmware, existe um método alternativo para rastrear todos os arquivos abertos em um determinado período de tempo. Vou sair daqui por uma questão de perfeição.

Você sempre pode usar uma ferramenta de rastreamento em tempo real capaz de seguir as chamadas do kernel como sysdig .

Então, depois de instalá-lo com

sudo apt-get install sysdig

Aqui você tem o rastreamento de todos os arquivos abertos por um Debian 9 VM depois que eu inseri meu ralink wifi USB pen. Infelizmente não há arquivos de firmware, caso contrário eles apareceriam no exemplo.

O formato do script sysdig é flexível o suficiente para restringir dados, usuários e nomes de arquivos conforme necessário para fins de depuração:

$sudo sysdig -p "%12user.name %6proc.pid %12proc.name %3fd.num %fd.typechar %fd.name" evt.type=open

Esta tabela reflete a versão mínima de cada firmware hospedado em linux-firmware repositório .git que é conhecido por trabalhar com esse módulo e com a versão do kernel. No seu caso específico, o arquivo é iwlwifi-6000g2a-6.ucode .

modinfo mostrará todos os arquivos de firmware que podem ser usados por esse módulo (e que podem suportar outro hardware). O wiki sem fio é uma maneira bastante confiável de obter informações sobre hardware e firmware.

dmesg | grep firmware pode ajudá-lo a investigar qual arquivo de firmware está sendo usado. Exemplo 1 - o firmware foi carregado corretamente:
