Dotaz: PCMCIA Option GlobeTrotter EDGE pada spojeni

[TNT]

Pořídil jsem si tuto kartu s předplacenou SIM od T-Mobile (http://www.czechcomputer.cz/product.jsp?artno=46358). Ve Windows spojení chodí dobře, ale v linuxu se vždy po přenesení nějakého množství dat spojení rozpadne a už nejde navázat znovu nebo to trvá desítky sekund.

Používám modul serial_cs (s ipwireless_cs, option ani pl2303 to vůbec nenajde modem).

Po vložení karty se v logu objeví toto:

pccard: PCMCIA card inserted into slot 0
pcmcia: registering new device pcmcia0.0
pcmcia: request for exclusive IRQ could not be fulfilled.
pcmcia: the driver needs updating to supported shared IRQ lines.
0.0: ttyS0 at I/O 0x93e8 (irq = 16) is a 16550A

Potom pomocí comgt -x GTEDGE a comgt -x nastavím kartu (jinak hlásí chybu už při AT...) a spojení vytáčím pomocí pppd, log vypadá následovně:

Potom to nějakou dobu chodí ale jakmile zkusím něco přenést (načíst html stránku apod), tak to obvykle spadne (např. test na http://www.rychlost.cz nikdy neprošel). V logu je potom najednou spojení ukončeno a pokus o automatické vytočení neprojde, čeká to velmi dlouho a karta nic nevysílá:

A tam čeká až dostane alarm a skončí. Může to souviset s tím sdílením IRQ na začátku? Vypadá to, že se to spojení rozpadne vždy při nějakém vytížení, když pustím třeba jen ping, tak to nevypadne snad vůbec. Můžete mi někdo prosím poradit?

Zdravim,

nevim jestli to pomuze - ted tu kartu nemam u sebe, ale kdyz jsem ji pouzival, tak fungovala bez problemu (ubuntu, dapper)

v lspci:

03:00.1 Serial controller: Broadcom Corporation: Unknown device 4333 (rev 03)

sama se detekovala jako ttySxx, nebylo treba zavadet zadne moduly

dmesg | grep -B 1 tty:
PCI: Enabling device 0000:03:00.1 (0000 -> 0001)
ttyS4 at I/O 0x4000 (irq = 10) is a 16550A

pro vytaceni jsem pouzival wvdial:

/etc/wvdial.conf pro T-mobile, bez PINu:

[Dialer Defaults]
Modem = /dev/ttyS4
Baud = 57600
Init1 = ATZ+CFUN=1
Init2 = AT+CGDCONT=1,"IP","internet"
Phone = *99***1#
Idle Seconds = 0
Username = a
Password = b

Nebyla to verze COMBO (s wifi)? Tuhle pres lspci vubec nevidim.

[Dan1]

pravda, byla to PCMCIA Option Globetrotter EDGE Combo (GPRS/Wi-fi) od T-mobilu, netusil jsem ze delaji taky verzi "necombo"

[kenny_1]

podivej se do /etc/ppp/options na lcp-echo-interval jaka tam je hodnota pokud je nizka, tak to muze padat, ja si davam 36000 ;) a na lcp-echo-failure 48 obvykle to pomuze ;)

[TNT]

Diky, to pomohlo! Sice se to obcas misto rozpojeni zasekne a par sekund nic neprenasi, ale spojeni se nerozpadne, takze uz je to pouzitelne.
