USB LTE modem - jak se připojit přes wvdial (O2 SIM)

[tuxmartin]

Ahoj, mam tu USB LTE modem Huawei E3372. Ma na sobe logo T-Mobile, ale mam v nem O2 SIM.

At delam, co delam, stale se mi na nedari pomoci wvdial pripojit k internetu.

Kdyz pouziiju na naklikani spojeni graficky Network Manager, tak spojeni bez problemu funguje. Vygeneruje si nasledujici nastaveni:

Kód: [Vybrat]

Jenze se mi nedari pripojit pres wvdial.

Modem se detekuje:

Netrvam uplne na wvdial. Stacil by navod, jak se pripojit pres pppd a chatscripty - ani to mi nefunguje.

[tnr]

Uz si to moc nepamatuju, tenhle modem uz nemam. Ale jestli me pamet nekalme, tak se da provozovat v dvou rezimech:
- Modem (obecne celkem na nic, potrebujes resit PPPD)
- cdc_mbim - funguje naprosto bez problemu.

Resi se to prave tim usb_modeswitch, do ktereho rezimu se to prepne.

Ja to pouzival prave v tom CDC rezimu, pak se to tvari jako normalni sitovka a ne jako znakove zarizeni + pres MBIM utility je mozne s tim modemem pracovat (signal, site, SMS atd.)

Ja mam HUAWEI USB E3131 a E1752 na OpenWRT.
Je to na SK O2.

Diky, zkusim se v tom nejak zorientovat.

Povedlo se mi pripojit pres NetworkManager (jinak jsem ho na ne-desktopu nikdy nesnesl). Vubec nechapu, jakou magii pouziva, ze mu to bez problemu funguje.

Modem a usb modeswitch funguje bez problemu:

"dhclient wwan0" (případně ekvivalent) se nechytá?

To jsem nezkoušel, ale ppp0 v té době ještě neexistuje.

Nezlobte se, ale vy mi přijdete trochu zabedněný.

To zařízení umí fungovat jako klasický modem (/dev/ttyUSBx) a také jako klasická usb síťová karta (wwan0). Pro použití jako síťovka se vůbec s žádným PPP nemusíte crcat. Už vám to tu radil jako první tnr... Prostě nakonfigurujte síť pro wwan0 jako by to byla síťovka a finito.

Diky, zkusim se v tom nejak zorientovat.
Asi budu muset prehodnotit svuj nazor na NetworkManager na headless pc...

Hele, ja te nechci prudit, nemyslim to vazne zle - ale pokud nechapes, jak funguje MBIM a NM, ktery ho spravuje, tak se na to proste vykasli a pouzivej proste NM / MM a bude to fungovat.

Zadny PPPD v rezimu CDC MBIM neni a nemuze byt. Spojeni tu navazuje primo modem, ktery se chova jako sitova karta + ma ridici kanal. PPP je tam jako rezim pro stare systemy, modem ho navic jen emuluje, protoze tam nikde PPP uz davno neni na stacku techto modemu. Do jakeho rezimu se to prepne urcuje prave usb_modeswitch. Existuje tam i CDC NDC (nevim zda ho tenhle umi, nebo ne) - pak se to chova jako USB sitovka a modem poskytuje typicky nejaky web interface pro konfiguraci.

Tzn rezimy jsou:
- Emulace starych modemu s PPPD (problematicke a casto nefunkcni)
- CDC NDC (nevim zda je u tebe podporovano, jine Huawei modemy to umi)
- CDC MBIM (viz nize)


Pokud chces pouzit modem v rezimu CDC MBIM, potrebujes:
- CDC MBIM driver v kernelu (coz na 99.999 % mas)
- ovladaci program

Ovladacim programem muze byt:
- mbimcli
- NetworkManager / ModemManager

Pouziti wvdial v tomto rezimu je totalni nesmysl a nemuze nikdy fungovat.

dhclient wwan0 nefunguje, cekal jsem to

Diky za vysvetleni. Tak nejak jsem predpokladal, ze kdyz se s modemem muzu bavit beznymi AT prikazy po /dev/ttyUSB0, tak ze pomoci nich bude mozne i navazat spojeni.

Pokud nefunguje, je třeba ještě zařízení před spuštěním sítě na wwan0 buď nahodit příslušnou utilitou (viz příspěvek tnr) a nebo to udělat ručně, např. posláním příslušné AT sekvence a poté již dhclient...:

# echo -e "AT^NDISDUP=1,1,\"internet\"\r" > /dev/ttyUSB0

# dhclient wwan0

Jinak samozřejmě máte pravdu, že se dá připojit i klasickým PPP, ale proč, kdy to jde jednodušeji a zařízení si to umí zařídit samo?

Tohle nejak nefunguje.
