sa drugih racunara ubuntu i win sistema konektuje se bez problema.
A kod neme na laptopu samo okrece obtain ip adress i nista...

Problem sam jedino resio rucno unosenjem IP adrese i dns.... ali zasto to tako mora?

Hm.. morao bi da budes malo recitiji ,da bismo pokusali da ti pomognemo.
Gde si uneo....IP adrese i dns? ....Imas li neki bezzicni ruter ili.... na koji uredjaj pokusavas da se konektujes?...itd....

untitle · 18.12.2012. 21.47

Ruter je huawei telekomov, probao sam sve moguce zastite i open mrezu i nece, samo se 2 puta na pocetku konektovao...
Ip adrese sam rucno uneo u network manager:
192.168.1.176,za subnet masku, 255.255.255.0 Za default gateway 192.168.1.1, i istu tu adresu (192.168.1.1) za DNS

Sa ovakvim parametrima radi. A na drugom laptopu sa istim ubuntom 12.10 radi automatski sa svim tipovima zastite i bez.

***Tomato*** · 18.12.2012. 22.25

Jel ti podesen DHCP server u ruteru (ako ima tu opciju) ?
Da li si svim ostalim racunarima dodelio staticke IP adrese u ruteru ili idu preko DHCP-a ?
Predpostavljam da si pokusavao u Network mendzeru sa DHCP u IPv4 i automatskom konekcijom.

untitle · 19.12.2012. 15.26

Valjda je podesen, a ostali uredjaju dobijaju automatski Ip adresu. instalirao sam i dhcp server ali opet nije hteo da uspostavi konekciju. Slabo se razumem oko tih stvari.

Koliko znam to da li je mreza Open ili ima neku zastitu ne utice na dodeljivanje IP adresa, ako se racunar poveze na bezicnu mrezu, dalje je isto kao sa kablom.

Ako radi automatsko dodeljivanje IP adresa na drugim racunarima na istom ruteru, onda verovatno nije do rutera nego do necega na tvom racunaru.

Mozda se klijent za DHCP (za automatsko dodeljivanje IP adresa) ne pokrece kako treba na tvojoj masini, to moze biti problem.

Takodje, ako je dosta slab signal moze biti da jednostavno racunar ne moze da komunicira sa ruterom iako se asocirao sa mrezom.

Kad se racunar poveze na wireless mrezu, probaj u terminalu da mi das komandu

Kod:

sudo dhcpcd wlan0

pa da vidis da li ce izbaciti neku gresku.

Ta komanda kaze sistemu da pokusa da automatski dobije adresu od rutera, a izlaz iz komande bi moga da kaze o kakvoj gresci se radi ...

untitle · 08.01.2013. 11.46

Izvini sto kasnim sa odgovorom, ali jos uvek nisam uspeo da se konektujem na mrezu i jako me to nervira.
Uradio sam ovo kao sto si napisao, samo sto nisam dok je bio konektovan vec dok se povezuje i naravno na kraju neuspe.
Evo izlaza iz terminala:

Kod:

sudo dhcpcd wlan0

err, wlan0: timed out

err, wlan0: lease information file `/var/lib/dhcpcd/dhcp~$ dhcpcd.sh: interface wlan0 has been configured with new IP=169.254.45.189

$ dhcpcd.sh: interface wlan0 has been configured with new IP=169.254.45.189

**zika** · 12.01.2013. 18.19

Šta kaže na

Kod:

sudo dhclient wlan0

...?
Da li ste probali da u

Kod:

/etc/network/interfaces

dodate

Kod:

# Wireless device- call this whatever you want

auto wlan0

iface wlan0 inet dhcp

wireless-essid networkessid

wireless-key 5BA323BF25

gde je poslednji redak optional ako postoji key (koji, naravno, valja zameniti pravim)...
Nakon toga

Kod:

sudo service networking restart

...

untitle · 15.01.2013. 13.36

Kada ukucam u terminalu prvu naredbu "sudo dhclient wlan0" izbacuje mi prozor system report eror, tako nesto.... i to vrti, dok ne pritisnem u terminalu ctrl + c da prekinem...
A kada ostale linije dodam u fajl, i restratujem mrezu. Nece da pokrene uopste network ...

darkojuca · 16.01.2013. 12.44

Citat:sudo lshw -C network

to imamo =

Kod:

...

E sad da vidimo ovo:

Kod:

iwlist eth1 scan

i ovo:

Kod:

iwconfig wlan0

Kod:

sudo dhcpcd wlan0

sudo dhclient wlan0

možda da probaš bez sudo

Razlika izmedju dhclient i dhcpcd je to što dhclient šalje samo jedan zahtev dhcp serveru i tu se sve završava. Dok dhcpcd stalno radi u pozadini i upravlja ip adresama.

Naravno ako želimo manuelno da upravljamo podešavanjima networka, onda moramo da eliminišemo NM, pošto će on uvek prebrisati naša manuelna podešavanja.

U slučaju da eliminišemo NM, onda će naš
etc/network/interfaces, izgledati otprilike ovako:

Kod:

auto lo

iface lo inet loopback

auto eth1

iface inet eth1 dhcp

wireless-essid "ime_mreže"

wireless-key "mesto_za_key" restricted

Ali pre svega probaj da dodaš ovu liniju:

Kod:

dhcp=dhcpcd

u
/etc/NetworkManager/NetworkManager.conf

restart NM-a:

Kod:

systemctl restart NetworkManager

Tako ćeš preći sa dhclient na dhcpcd, ako to ne upali onda dakle uninstall NM i probaš da konfigurišeš "interfaces"

evo kod mene sad sam probao na netbook da povezem tl-wn422g wi-fi prijemnik. kad sam ga povezao, docekalo me veoma prijatno iznenadjenje....
ubuntu je prepoznao i ugradjeni i tp-link prijemnik! mogu da ukljucim samo jedan ili oba, kako sam ubacio tako je proradio.

verzija je 11.10 doduse...
