Mam tento nb a nahodil som nan Ubuntu 8.04. Nic som nenastavoval. Na desktope s XP Pro som spustil ad-hoc siet bez hesla:
overenie: otvorene
sifrovanie: zakazane
V ubuntu mi ziadnu siet neukazuje(vobec, aj ked su tu dalsie 2 wifiny). Skusal som sa pripojit cez nazov siete ale nic. Takze som cez usb prekopiroval do nb balicky ndiswrapper common a ndiswrapper utils. Tiez som prekopiroval na usb ovladac na sietovku(bcmwl5.inf). Ten som cez ndiswrapper nainstaloval podla wiki a doplnil do /etc/modules na koniec "ndiswrapper". Resetol som nb. Opät mi ziadnu siet neukazuje. Zase som skusil rucne pripojenie na siet ale zase nic. Tak som zadal manualnu konfiguraciu pre wifi a nastavil essid kde som dal nazov siete, nechal som wpa personal(nie je tam none) a nevyplnil heslo. Dal som staticku ip 192.168.0.5, masku 255... a gateway 192.168.0.1(co je ip wifini na desktope). Ale ziadnu siet mi stale neukazuje.
Cize neviete niekto ako rozbehat tu wifi siet?
Skusla som aj opensuse 10, ale bez ndiswrapperu, len to co sa nainstalovalo z dvd(=cista instalacka), ale tiez som sa nikam nedostal.
Teraz mam na nb dualboot xp/ubu a rad by som sa aj z linuxu dostal na net cez desktop.

Ovladace na wifi kartu vypadaji v poradku, i kdyz to iwlist scan je divne ze nevidi zadnou sit. Poslete prosim jeste
iwlist wlan0 txpower
-
wlan0 unknown transmit-power information
current tx-power=0 dBm (1 mW)
cize ak spravne chapem, tak karta nie je aktivna(svetielko nesvieti :D )
-
Ted jsem si vsimnul, ze to txpower je videt z vypisu iwconfig. ::)
Karta je aktivni, ale ma nastaven slaby vykon konretne 0dBm.
current tx-power=0 dBm (1 mW)Blbe je, ze se mel zobrazit seznam dostupnych vykonu, ktere se daji nastavit. Coz se neudelalo (viz. prvni radek)
wlan0 unknown transmit-power informationZkuste tedy nastavit napriklad vykon 20dBm.
sudo iwconfig wlan0 txpower 20A pak poslete: (nenastavujte zadny ESSID, ani nic jineho.):
iwconfig
iwlist scan
Jeste doporucuju precist clanek v me paticce. ;)

Nemohu posoudit. NTB má známá, instaloval jsem tam 7.10. K internetu je připojená přes kabel a wifi tak nemohu odzkoušet.

Nevim jestli to k něčemu bude, ale mě to ukazuje toto:
karel@karel-Neo:~$ iwlist wlan0 txpower
wlan0 unknown transmit-power information.
Current Tx-Power=27 dBm (501 mW)
WiFi mám vypnutou a žádná síť se mi taky nepodařila najít (se zapnutou WIFI :-)) )
Nic jsem nedoinstalovával

Ok, takze som to vyriesil. Musel som si stiahnut b43-fwcutter a firmware. Cez fwcutter som nainstaloval firmware a resetol a vsetko ide ako ma. Len teraz som zistil ze to iste musim spravit aj na dekstope(rt2500), lenze tam uz je to o dost zlozitejsie a zatial neviem ako dalej. V kazdom pripade nb uz fici ako by mal.
