New connections can't be made once the first has been closed
You can connect to the network once. But after you disconnect, you have to turn the modem off and back on before you can reconnect to the network. After the unsuccessful attempt to reconnect, you'll see something like this in /var/log/messages:
Jul 20 19:53:32 localhost pppd[5321]: pppd 2.4.4 started by root, uid 0
...
Jul 20 19:53:33 localhost chat[5322]: send (ATZ^M)
Jul 20 19:53:33 localhost chat[5322]: expect (OK)

Daniel Kozák discovered that he could solve this problem by making another driver handle AnyDATA modems. This driver was originally made for GSM/GPRS cards made by Option, and is named 'option'. More information - in Czech - here(http://www.abclinuxu.cz/forum/show/123212) and here(http://kozzi.php5.cz/new.html). This fix is included in the standard kernel since version 2.6.18. Some vendors backported the fix to their versions of the kernel. For instance, it is included in Ubuntu Dapper kernels since update 2.6.15-26. For others, here are versions of the patch for recent kernels:
Patch for 2.6.15 download (http://jk.ufisa.uninett.no/anydata/option-handles-anydata-2....)
Patch for 2.6.16 download (http://jk.ufisa.uninett.no/anydata/option-handles-anydata-2....)
Patch for 2.6.17 download (http://jk.ufisa.uninett.no/anydata/option-handles-anydata-2....)
Все вышесказанное так-же применимо к AirPlus MCD-650.
