兄弟看一下这个。这个网卡应该能解决，资料很多。


T-Mobile Internet on Linux
The wireless data landscape
T-mobile lowered the price on their unlimited data option. It's now $30/month ($20 if you already have a voice plan) whereas all the other guys are at $80/month (Verizon, Sprint) or they don't offer unlimited at all (AT&T).

It should be noted that GPRS (T-Mobile, AT&T) is slower than 1xrtt (Verizon, Sprint). GPRS is rated at a max of 56k but 1xrtt is supposed to reach 144k. I haven't tried 1xrtt but I can tell you that the rates I get with GPRS are well below 56k. T-Mobile may not have a speed advantage, but you have to give it to them for their price advantage.

Verizon is starting to deploy a real 3G network in some cities (Washington DC was one). At some point it may be worth looking into a bluetooth phone from Verizon that can do 1xrtt and also cdma2000 aka 1xEV aka 1xEV-DO once it's deployed in my town... I asked Verizon which phones could do all that and they were basically clueless (maybe because they are resisting bluetooth adoption for some reason).

Verizon sells a PCMCIA card made by Qualcomm ("C 5220" for "CDMA 1xEVDO") that is supposed to handle 3G as well as current technologies. It is not supported in Linux however. It shows up as a USB adapter with an unknown device attached:

Sierra Wireless plans to have a strikingly similar high-speed card (Aircard 580) out in 2004. No official Linux support, but they may provide hints about how to use it like they do with their other cards.

This is intriguing... GSMTM? http://www.pcclub.com/edge/
Hardware
I originally opted for the Sierra Wireless Aircard 750. I'm not going to use T-Mobile for voice much and I figured I didn't need one more device to keep charged. (Actually, you can make voice calls using this card; under Linux you might be able to use an approach similar to the what one Linux user did on an Aircard 555.)



Set up the windows software and make sure the card works under windows. This registers the card and also updates the firmware.
Driver
Get the pcmcia files from Sierra Wireless. They also provide some of the config information below but not specifically for T-Mobile's network. Note that a recent pcmcia package may already have these settings in place.
Configuration
These are the main places to get the configuration right. I'm calling my configuration tmobile in these examples...

Regarding "internet2" below in the configuration... from a post by MattPackwood@cs.com:

If you have an "Internet Plan" you can access wap.voicestream.com and internet2.voicestream.com.

If you have the "ro" or "VPN" service (there is no extra cost for this compared to a "regular Internet Plan") you can access internet3.voicestream.com and wap.voicestream.com (but NOT internet2.voicestream.com!).

So use whatever works, but take note that internet2 will give you "private" IP addresses so there may be some network services that don't work.

/etc/ppp/peers/tmobile:

noauth
connect "/usr/sbin/chat -v -f /etc/chatscripts/tmobile"
debug
/dev/ttyS1
57600
defaultroute
noipdefault
user ''
remotename tmobile
ipparam tmobile
crtscts
idle 300

/etc/ppp/chatscripts/tmobile:

ABORT ERROR
'' ATZ
OK AT+cgdcont=1,"IP","internet2.voicestream.com"
OK ATD*99#
CONNECT ''

/etc/ppp/pap-secrets:

(none)  *       password
'' tmobile

/etc/ppp/resolv/tmobile:

nameserver  216.155.175.40
nameserver  216.155.165.50
You must hardcode the DNS servers this way when using the Sierra card for some reason. Trying to get PPP to discover the servers always made the connection fail for me. You may want to try your own ISP's DNS servers if this one doesn't work.

I suggest you disable image compression on http://getmorespeed.t-mobile.com. You must be using t-mobile DNS in order for getmorespeed to resolve.

/etc/ppp/options:
You MUST disable the lines that give values for lcp-echo-interval and lcp-echo-failure or your connection will always terminate (eg after two minutes). It appears that GPRS providers do not reply to lcp echo requests but pppd normally uses these to determine if the connection is still good.

/etc/apm/event.d/ppp:

#!/bin/sh

# stop and also restore ppp connection

case "$1" in
suspend)
/usr/bin/poff
;;

resume)
(sleep 15 && /sbin/ifconfig eth0 >/dev/null 2>&1 || pon tmobile) &
;;

esac

This script ensures that ppp isn't holding onto the port when the laptop is being suspended. This reduced the need to eject and reinsert the card. The connection will be restored at resume time if no ethernet card is present.
Fire it up
On my Debian box, I just issue

pon tmobile

to get it to run. There are significant delays while the chatscript runs, while it's waiting for a reply to modem commands. Actually if it runs without the pauses, something is probably wrong.

I had a lot of trouble whenever a connection failed. I invariably had to either eject the card and reinsert, restart pcmcia services, or both. The Linux driver seems to get in a strange state especially after a failed connection. The card seems to run hot if it's connected for a while and that's often when I see trouble.

When you fire up ssh, use the -C option to enable compression.
Bluetooth
I also have the Socket communications CF "G" model bluetooth adapter and I've set things up with a Nokia N-Gage. This configuration actually works a lot better than the card above. I get much better coverage and basically no connections hanging. Too bad I didn't try this route first.

I installed bluez from cvs, installed pcmcia-cs from unstable.

I set up a resume script in /etc/apm/event.d/bluetooth that starts and stops the bluetooth card:

#!/bin/sh

# stop and also restore bluetooth

case "$1" in
suspend)
    rfcomm release 0
    killall hciattach
    sleep 2
    ;;

resume)
    # this belongs in pcmcia serial script (?)
    hciattach /dev/ttyS1 socket
    hciattach /dev/ttyS3 socket
    rfcomm bind 0 00:60:57:85:BD:5B 1
    ;;

esac

Note this stuff really should be in the pcmcia scripts but I hate to make changes to scripts that will be overwritten when I update the pcmcia package. The only problem I see with this for now is that stuff doesn't come up when I start up the machine, only when I resume it. I rarely have to reboot my laptop so it's not much of an issue.

I use a new config in /etc/ppp/peers/tmobile:

noauth
connect "/usr/sbin/chat -v -f /etc/chatscripts/tmobile"
debug
/dev/rfcomm0
115200
defaultroute
noipdefault
user ''
remotename tmobile
ipparam tmobile
crtscts

The bluetooth setup is very nice. I never have to think about what card is inserted since I leave the bluetooth card in. Whenever I resume my laptop without an ethernet card inserted, it goes online using my Tmobile connection. I don't even have to think about it any more--it's there when I need it.

The AirCard7x0.zip contains SW_7xx_SER.dat, ac750, and ac750chat files

How to Configure Linux to Recognize AirCard 710/750

Before you start, make sure that the AirCard 750 is not inserted into the PCMCIA slot.
The following instructions will configure the AirCard 750 as a serial-only device on Linux:

1. Add the following to /etc/pcmcia/config under the Modems and other serial devices:

card "Sierra Wireless AC710/AC750 GPRS Network Adapter R1"
manfid 0x0192, 0x0710
cis "cis/SW_7xx_SER.dat"
bind "serial_cs"

2. Copy the file SW_7xx_SER.dat in this archive in /etc/pcmcia/cis/
3. Restart computer.
4. Insert the AirCard 710/750

When the card is inserted two high beeps should be heard, indicating that the AirCard750 has been recognized and the serial driver has been successfully loaded. The AirCard750 can be accessed as /dev/modem when inserted. Running minicom should allow access to the AT command interface.

找到这一段，真是太谢谢　北南南北　老兄了！
看样子有戏，可是这一段
1. Add the following to /etc/pcmcia/config under the Modems and other serial devices:

看不太懂，初学linux，还请DX指教。

附上所需的文件，如果成功了，建议将此贴列为精华，因为现在国内用这个卡玩无线的人是最多的了。

那个目录下没有config这个文件，是不是要自已加？用什么加，什么格式的呢？

经过几个小时奋斗我的linux已经认出了我的网卡并且拔号连接成功！

但是，连接上以后，却还是上不了网，打入一个网址，就在解析网址，我就设了DNS，改了几个都不行，这是什么原因啊？

昨晚还能连上，今天却连都连不上了，停在“正在网络注册”，不知道咋回事，如下：
