Asensin Asus Eee PC 901:lle Ubuntu Netbook 10.04, jonka jälkeen langaton verkkoyhteys lakkasi toimimasta. Kyseessä on DHCP:tä käyttävä wlan.
Nyt kone tunnistaa verkon, kysyy salasanaa yhdistäessä, ja jumittaa sen jälkeen. Muutaman minuutin kuluttua se kysyy salasanaa uudestaan, on yhdistävinään, ja sitten kysyy taas salasanaa.
Aiemman version aikaan (Ubuntu Netbook Remix 9.04) kone yhdisti langattomaan verkkoon mukisematta.
Olisiko tähän jotain simppeliä ratkaisua? Useimmat netistä katsomani ratkaisukeinot menevät aloittelijan taitojeni yli...

Minulla kyllä toimii ihan hyvin. Juuri sama kalusto ja sama jakelu. Tarkemmin sanoen kokeiltu liveajolla asentamatta vielä lopullisesti 10.04 sekä netbook, että desctop jakelulla. Siinä kokeillessa oli tukiasemani WEP-40 salauksella ja peitetyllä verkkonimellä. Sitten sattui niin, että tukiasema meni rikki ja uudessa ei ollut sitä 40 bittistä WEP:tä, joten vaihdoin WPA-WPA2 salaukselle. Sen kanssa jostain syystä kävi niin, että vaikka Lucid pelitti hyvin toisessa koneessa, niin edelleen tässä eee 901:ssä oleva Jaynty ei suostunut yhdistymään peitetyllä verkkonimellä. Miksi niin on, jäi arvoitukseeksi ja verkkonimi on nyt näkyvä, mutta salaus vahva WPA ja sekä Lucid toisessa koneessa, että Jaynty eee:ssä pelittää. Mutta koitin edelleen liveajona sd-kortilta Lucidia eee:ssä ja siinäkin wlan toimi vain, jos verkkonimi ei ole peitetty. Kumma juttu.

Olisikohan tuossa 901:ssä useampia eri wlan-kortteja riippuen tuotantoerästä tai vastaavasta? Minulla on sama kone tavan Ubuntu 10.04:llä ja yhdistyy wpa2-salattuun wlaniin, jossa verkon nimi on näkyvissä, mukisematta.
Saan komennolla lshw -C network seuraavaa tietoa tuosta kortista:

Kuten jo kerroin, ehkä sekavasti, niin eee 901 yhdistyy wlan verkkoon vahvalla tai heikolla wpa salauksella vain jos on näkyvä verkkonimi. Jos verkknimen peittää, niin ei yhisty vaikka millä houkuttelis. Ja juuri tuo sama wlan-sovitin rt 2860.
Vieressä on toinen asus a6r jossa, yleensä mestarikenkkuilija, broadcom air force one ja pelaa kuin juna mutkassa kaikilla vaihtoehdoilla. Jopa koneen käynnistyksessä yhdistyy aina aivan hetkessä ja odottelematta. Ja kävin tosiaan läpi kaikki tukiaseman tarjoamat suojausvaihtoehdot mac suojausta myöten.
(Kaikilla konsteilla työmiestä masennetaan! Jos ei anneta tylsää kirvestä, niin ainakin liian pienet haalarit!)

Olisikohan se tuo inet6 asetus. Minulla on asetukset näin:

Ei ipv6:lla pitäisi käsittääkseni olla väliä tässä tapauksessa.
