Realtek 8723 ne radi ?

Veliki pozdrav svim ljubiteljima, korisnicima i majstorima Linux Mint-a !

Nov sam korisnik Linux-a i odlucio sam se za Mint jer na desktop-u imam Maya-u i sve ide savrseno.
Imam kucni wireless router preko koga, drugim laptopovima, pristupam internetu bez ikakvih problema.
Dakle TP-Link radi. I to dobro.

Sada imam veliki problem da osposobim wireless na tek kuplljenom laptopu Toshiba Satellite C855-12W i tek instaliranoj Maya-i.

Kada u terminal-u unesem:

sudo iwconfig

u rezultatu ne dobijam prisustvo wlan0 vec dobijam samo lo i eth0 (oba kao no wireless extension).

Kada unesem:
sudo lshw -C network -numeric

Dobijem sledece:

Iz ovoga sam, kao novajlija u Linux-u, zakljucio da imam potreban hardver pa sam probao instalacije dodatnih drivera koje sam pronasao na google-u ali nista ne uspeva da ozivi moju karticu…
Probao sam sledece :
rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012
compat-wireless-2012-07-03

Jos jedna stvar. Pokusao sam da unesem Wireless connection i u Network Connections sam dodao konekciju tako sto sam uneo SSID za kucnu mrezu, postavio Mode na Infrastructure, uneo MAC address, postavio Wireless Security na WPA & WPA2 Personal, i uneo lozinku za mrezu.
I nista.

Ima li neko iskustva sa ovom WiFi karticom i/ili Satellite laptopom ?

(izvinjavam se na dugackom post-u i verovatno se neki od prethodnih rezultata preklapaju ali sam malo ocajan…)

Hvala puno na pomoci !

Koji je izlaz komande sudo ifconfig -a?

izlaz sudo ifconfig -a daje:

Skini ova dva fajla i instaliraj… To su drajveri za tvoju wlan karticu.

Skinuo fajlove. Instalirao. Sve radi savrseno !!!
Veliko hvala !!!

p.s. : cisto evidencije radi, u mojim “pokusajima” sam instalirao ovaj drugi fajl ali umesto prvog sam instalirao compat-wireless; izgleda da je tu bio problem; toliko ja mogu da razlucim sta se zapravo desilo; jos jednom hvala !
