Wifi v Backtrack5 R3

Zdravím vás

Mám problém s ktorým si už 2 dni lámem hlavu a neviem ako to vyriešiť. Vytvoril som si botovatelne USB Backtrack5 KDE R3 pričom pekne mi ho nabotuje a spustí no problém nastane keď začnem hľadať wifi kartu lebo mi žiadnu wifinu ani originál z notebooku ani externú na USB ALFA chip Atheros 9271 a nefunguje taktiež ani ratlink ani Broatcom nenájde ani po zadaní príkazu IWCONFIG. Jedna sa o notebook ACER aspire V5 171 . Keď to všetko napojím príklad na asus alebo na Lenovo všetko pekne ide a šlape ako ma. Neviem či mam skúsiť preflešovať Bios alebo čo dalej ak mate niekto s tým skúsenosť tak dajte vedieť dik.

EDIT: Ani zmena biosu za staršiu verziu nepomohla momentálna je tam od aceru 1.09 pre win 7

backtrack r3 vysiel v auguste 2012, na interne sietove karty v tom notebooku pravdepodobne nema v sebe potrebny driver.. preco nejde externa si neviem poriadne vysvetlit, leda ze by chybali nejake potrebne drivery na usb alebo chipset.., odporucam stahnut novsiu verziu (backtrack bol nahradeny distribuciou kali linux )

Ta externá USB ALFA chip Atheros 9271 na iných počítačoch s tým istým botovacim USB ide pekne aj wifi karty čo sú v tých notebukoch zabudované. Nejde to len na tom Aceri čo som kupil nový ACER aspire V5 171. Jedna sa o Backtrack 5 R3. Ono mam dojém ako keby notebook nepodporoval linux alebo len wifi v linuxe ozaj som s toho mimo skúšal som aj klasicky xiopan ani tam mi nenašlo žiadnu wifi kartu.

Wifi karty co su v notebookoch zabudovane potrebuju mat driver.. Je velmi caste, ze pri kombinacii novy notebook, stary linux ten linux driver pre potrebny chip neobsahuje a teda zabudovana karta nefunguje

Tu USB kartu strkas do USB 3.0 alebo 2.0, nieco ine v tom porte funguje (napr. iny usb kluc)? Je vseobecne zname ze pred nejakym casom (napr. pred tym rokom ked vysla aktualna verzia backtrack-u) boli na linuxe problemy s usb 3.0..

Ak chces vylucit compatibility issues, tak stahni nejaky lubovolne naupdatovany linux so vsetkymi najnovsimi drivermi (napr. ubuntu 13.10 by mohla obsahovat dostatocne novy kernel a drivre, ked tak este dotiahnut k nej najnovsi balik compat-wireless na sietove karty). Na 99% je to problem ze ti chybaju nejake drivere...

Ked sa ti chce zistovat preco ti to nejde, mozes pripojit ten "alfa chip" a hodit sem vypis tychto prikazov (spustaj ich ako root):

ak niektory z nich bude prilis dlhy (napr. lshw), presmeruj ho do suboru a potom sem hod obsahy tych suborov, napr.

V USB3 mam zapnuté botovacie usb. A anténu Alfa a Myš mam zapojene v uzb2 pričom myš pekne funguje.
Stiahol som ubuntu 13.10 tak zajtra to skúsim cez neho a dám vediet. Kompletný výpis máš tuto dole:

EDIT: Na ubundu 13.10 mi wifi Alfa naskočila ale wifi z notebooku nie no potrebujem aby mi to šlo v Backtrack 5 R3 ešte skúšam nejaké ovládače uvidím ako to dopadne.
