Buon salve, di questi tempi non v'è tempo da perdere, quindi andiamo subito al tuorlo!
Come da titolo lavoro sotto BackBox Linux, kernel 2.6.38-15-generic-pae. Quando collego la scheda esterna "Alfa network AWUSO36H" il manager di rete grafico, mi risponde con: "rete senza fili (manufacturer realtek rtl8187 rtl8187 wireless) dispositivo non pronto". So per certo che la scheda funziona, poiché su Ubuntu 12.04 Precise, gira perfettamente.
I moduli rtl8187 sono installai perfettamente come si può osservare dal seguente output:
Quando cerco di mandare in up la scheda il sistema mi risponde con "argomento non valido":codice:sinec@dante-HP-630-Notebook-PC:~$ sudo lsmod Module Size Used by rtl8187 55996 0 eeprom_93cx6 13134 1 rtl8187 binfmt_misc 13213 1 vboxnetadp 13323 0 vboxnetflt 27855 0 vboxdrv 219250 2 vboxnetadp,vboxnetflt rfcomm 37332 8 bnep 17617 2 joydev 17322 0 parport_pc 32111 0 ppdev 12849 0 btusb 17911 0 snd_hda_codec_hdmi 27535 1 snd_hda_codec_realtek 255882 1 snd_hda_intel 28209 3 arc4 12473 4 snd_hda_codec 90901 3 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel ath3k 12786 0 snd_hwdep 13274 1 snd_hda_codec snd_pcm 80042 3 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec uvcvideo 66851 0 ath9k 115624 0 bluetooth 182891 25 rfcomm,bnep,btusb,ath3k videodev 75143 1 uvcvideo snd_seq_midi 13132 0 snd_rawmidi 25269 1 snd_seq_midi mac80211 460893 2 rtl8187,ath9k snd_seq_midi_event 14475 1 snd_seq_midi snd_seq 51291 2 snd_seq_midi,snd_seq_midi_event i915 451088 3 ath9k_common 13780 1 ath9k ath9k_hw 379968 2 ath9k,ath9k_common ath 19182 3 ath9k,ath9k_common,ath9k_hw snd_timer 28659 2 snd_pcm,snd_seq snd_seq_device 14110 3 snd_seq_midi,snd_rawmidi,snd_seq hp_wmi 13418 0 drm_kms_helper 40971 1 i915 sparse_keymap 13666 1 hp_wmi drm 184164 4 i915,drm_kms_helper cfg80211 177896 4 rtl8187,ath9k,mac80211,ath psmouse 59039 0 snd 55295 16 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device rts_pstor 348243 0 soundcore 12600 1 snd snd_page_alloc 14073 2 snd_hda_intel,snd_pcm serio_raw 12990 0 compat 16044 11 rtl8187,rfcomm,bnep,btusb,ath3k,bluetooth,ath9k,mac80211,ath9k_common,ath9k_hw,cfg80211 i2c_algo_bit 13184 1 i915 video 19112 1 i915 lp 13349 0 parport 36746 3 parport_pc,ppdev,lp ahci 21591 2 r8169 46630 0 libahci 25548 1 ahci sinec@dante-HP-630-Notebook-PC:~$
