Kokeilin tikulla käynnistystä ja lankayhteys meni heti laakista päälle.

Koneen oman Xubuntun käynnistyessä nettiyhteys syntyy myös heti( langattomana) kun nettikaapeli on irroitettuna ja koneen buuttaa normaalisti.

Kun nettikaapeli on kiinni ei mitään yhteyttä synny. Yhteyskuvakkeessa on teksti ruksattuna
"Enable networking" ja sekin harmaana eikä muuteltavissa, muita vaihtoehtoja ei siinä näy
esim. langattoman verkon yhdistämisestä.

Näinollen voisi olettaa, että koneen rauta on kunnossa. Sen sijaan joku vipu on päivityksen yhteydessä
mennyt poikittain. Näkeekö mistään mitkä ovat viimeisimpiä päivityksiä, mitkä on asennettu ja voiko niitä perua?

Tai muita vinkkejä?

[raimo]

Näkeekö mistään mitkä ovat viimeisimpiä päivityksiä, mitkä on asennettu

Apt historiatiedot näkyy näin:

cat /var/log/apt/history.log

En tiedä, pystyykö kukaan  noista päivityksistä  mitään sanomaan.

Täytyy olla joku noista 16 ja 17 syysk. päivityksistä, todennäköisimmin 17.9 :

[ajaaskel]

Katselin toisaalta hieman. Tämän viestin

https://launchpad.net/~foresto/+archive/ubuntu/extradrivers

perusteella näyttää että Marvell: in ajuri olisi vaihtunut tuosta "sky2" nimisestä joksikin toiseksi ja uuden paketin ylläpitäjäkin haluaa eroon ylläpitotehtävästä kun hänellä ei ole enää rautaa jolla testaisi (vapaa käännös tuolta).


Voisi katsella siellä mainittuja "blacklist" asioita ja ajuria, luulen että ollaan aika lähellä mitä on tapahtunut.

Jos muuttelet "blacklist" asetuksia niin ne tulevat voimaan vasta kun "initrd" tiedot on päivitetty ja kone käynnistetty uudestaan tämän vinkin mukaisesti:

https://bugs.launchpad.net/ubuntu/+source/kino/+bug/6290/comments/78

[Pendeli]

En uskaltanut ruveta noita blacklistoja sorkkimaan, mutta löysin asiaan liityvän listan. Siinä ei näy Sky2:

# Warning: This file is autogenerated by bcmwl. All changes to this file will be lost.
blacklist b43
blacklist b43legacy
blacklist ssb
blacklist bcm43xx
blacklist brcm80211
blacklist brcmfmac

blacklist bcma

[Pendeli]

Kun tuolta vanhoja juttuja kaivelin, niin löysin jollain saman vian eli lankayhteys ei toimi. Siinä pyydettiin
seuraavia komentoja (joilla tosin sekäänei  asiaa auttanut kyseisessä tapauksessa).
Toivottavasti tuosta olisi  apua asian ratkaisuun:

Katsotaan mikä ajuri on ladattu Ethernetille (jos mikään):

Koodia: [Valitse]

lsmod | grep -i sk
Näyttäisi että Marvellin Ethernetille on kahta eri ajuria eli "sky2" ja "sk98lin".

Ylläolevassa esimerkissä ei langallista yhteyttä ole olemassakaan, koska verkkopiuha ei ole kiinni. Mutta langaton toimii, kuten viestinlähetyksestä voi päätellä.
WLAN-verkkoa ei ole esimerkissäsi ole käytössä.

Vaikka verkkopiuha on kiinni, niin komento antaa samat tiedot.

Onko vika silloin verkkokortissa vaiko modeemissa?

Voiko joku asetus estää wlan-verkon toiminnan tai  terminaalissa näkymisen?

[Pendeli]

Tässä häipyi se toimivakin langaton yhteys. (Nyt varakoneella).
Koneelta löytyy tiedosto broadcom wl-4.150....tar.bz2
jonka uskoisin olleen viimeinen toimiva ajuri.
Kuinka saan tuon asennettua?

Jossain oli ohje tar xfj broadcom jne.
Mutta ei se ainakaan terminaalissa auta. Valittaa child jotain.
Ei kai löydä kohdetta.

Mitä pitää tehdä?

[joonas60]

Broadcomin bcm43xx-sarjalaisilla on oma Ubuntu-sivunsa https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx. Sivusto näyttää olevan kutakuinkin ajantasalla.

Oletuksena Ubuntussa on päällä avoimen koodin b43, mutta sen saa vaihdettua Broadcomin wl-ajuriin (sinulla näyttäsi tämä olevan viestien perusteella käytössä).

[Pendeli]

OK latasin sieltä .
b43 (12.04 Precise Pangolin)

ja Ohjeen mukaan pitäisi b43-fwcutterilla purkaa:

tar xfvj broadcom-wl-5.10.56.27.3_mipsel.tar.bz2
sudo b43-fwcutter -w /lib/firmware broadcom-wl-5.10.56.27.3/driver/wl_apsta/wl_prebuilt.o

 Milläs sen purkaa jos mitään fw-cutteria ei löydy?

[joonas60]

b43-ajurin on jo tai pitäisi olla koneellasi. Kokeileppa:

Koodia: [Valitse]

sudo modprobe -r wl
sudo modprobe b43
Sitten allaolevalla komennolla pitäisi nähdä lähtikö homma toimimaan:

Koodia: [Valitse]

dmesg | grep b43

Edit. Korjattu bl43 -> b43

[Pendeli]

Ei mitään reagointia kyseisiin komentoihin
ja FATAL: module b143 not found.

Jossain mätää?

Entäpä tuo broadcomin ajurin asennus?

[joonas60]

Korjasin aiempaan viestiini ajurin nimen oikeaksi. Pahoittelut.

Onko sinulla vielä se blacklist olemassa, jossa mm. b43-ajurit estetty? Toisaalta mitä allaolevat komennot tulostavat?:

Koodia: [Valitse]

sudo lshw -C network
ifconfig
rfkill list all
lsmod | grep "wl\|b43"
Edit. poistettu komennon lshw ylimääräinen välilyönti.

[joonas60]

Entäpä tuo broadcomin ajurin asennus?

Broadcomin omaa ajuria kokeilin USB-muistille asennetulla xubuntu 14.04.1 live-imagella  HP:n miniläppärillä, jossa on Broadcomin BCM4312 WLAN-piiri. Se ei lähtenyt suoriltaan toimimaan, valitteli puuttuvista firmware-tiedostoista, joten päätin kokeilla tuon antamani linkin ohjeita mukaillen:

Lähes välittömästi WLAN alkoi toimia ja löysi langattomia verkkoja. Minulla oli käytössä Huawei E5776 WLAN-4G-modeemi, jolla pääsin Internettiin.

Tuolla Xubuntu 12.04 homma menee varmaan suurin piirtein samoin kuin minulla (libfakeroot ei ilmeisesti tarvitse asentaa)
