联通的cdma无线网卡

clayton · 发表于 2007-6-11 17:51:44

你好,

我不是中国人所以用互联网研究不容易.
如国这儿不是好的地方问这样的问题, 请告诉我比较好的地方.

我的问题是, 我买了一张联通的cdma无线网sim卡.
我也找到了一张没有问题的usb的cdma的无线网卡.

可是用这张卡试一试上网的时候, 联通的ppp服务器不给我回答.

下边可以看我的情况. 有人有想法吗?

you can try wvdial.
and put wvdial's log.

Here comes the steps.
1. First you need let your keneral to support USB.
2. Reboot your system and you can find your CDMA has been found. Or check it
out with dmsg.
3. After that, the device should be added. Some use /dev/ttyUSB0, some use
/dev/input/ttyACM0 like mine. You can use cat /dev/input/ttyACM0 to verify it.
4. Config the wvdial with /etc/wvdial.conf.
++++++++++++++++++++++++++++
[Modem0]
Modem = /dev/modem
#Baud = 230400
Baud = 115200
SetVolume = 0
Dial Command = ATDT
Init1 = ATZ
FlowControl = Hardware (CRTSCTS)
[Dialer cdma]
Username = CARD
Password = CARD
Phone = #777
Stupid Mode = 1
Inherits = Modem0
++++++++++++++++++
5. wvdial cdma . Then the pppd will be run.
6. After this, you still need to do one more thing. Since the server won't add
the DNS server for you like the WINXX.
In your /etc/resolv.conf, add the following lines.
nameserver 220.192.8.58
nameserver 211.97.168.129
The nameserver you can check it out in your window 2K using CDMA to access
the internet.
ifconfig /all
After that, you can enjoy CDMA1X.

Thanks a bunch, Yuri, I will give it a try next time I head to Zhongguancun. Something tells me that "Stupid Mode" is probably what does the trick.

Your Chinese is pretty good!
But I haven't use a CDMA card to connect to Internet~

Yuri, I finally bought this card:
http://www.chinawiki.info/doku.p ... oadband:linux:c610u

wvdial works amazingly well, considering how much headache I had from kppp and pppd (which I still have not seen working in this context). I pared your wvdial script down to the bear essentials:

/etc/wvidial.conf:
[Dialer cdma]
Modem = /dev/ttyUSB0
Username = CARD
Password = CARD
Phone = #777
Stupid Mode = 1

Note that in fact "Stupid Mode" does not seem to be essential, it just speeds up the process.

I also found that on my Debian testing machine, /etc/resolv.conf gets updated automatically, so there is nothing to do after "wvdial cdma" except start surfing. I think on Debian the resolvconf package takes care of /etc/resolv.conf.
