[Bug 991680] Re: [SOLVED]Huawei E220 and E1550 can't connect on Ubuntu 12.04
It seems many people using more recent editions of Ubuntu and its ofshoot Linux Mint (LM) are reporting problems achieving mobile broadband connections with older Huawei modems. This is despite these modems working well in previous Ubuntu and LM editions. I believe that many of these problems may be due to a bug in the ModemManager Huawei plugin. I have a Huawei modem branded as an E160E but the 'lsusb' command gives the following specifications: 'Bus 001 Device 006: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem / E230/E270/E870 HSDPA/HSUPA Modem' The modem functioned perfectly well in Ubuntu 10.10 and LM 10 but I have had problems connecting in more recent Ubuntu and LM editions, including the latest Ubuntu 12.04 and LM 13. Sometimes after various "fiddles" including plugging and unplugging the modem a number of times, it is recognised by network manager and it may be possible to set up a connection and actually connect. But the work involved to achieve this is really not acceptable. After plugging in the modem, there is a partial system "freeze" for a couple of minutes, during which programs may run spasmodically and it is only possible to type intermittently in a terminal. Finally issuing a 'dmesg' command indicates that the modem is disconnected. After trying various recommended solutions, I came up with following: 1. Backup the file '/usr/lib/ModemManager/libmm-plugin-huawei.so' and replace it with the same file from Ubuntu 10.10 (or LM10). You could get this by running the live CD from one of these editions. After plugging in the modem, there is no more system freeze and issuing a 'dmesg' command indicates that the modem is attached to ttyUSB0 and ttyUSB1. 2. Setup an internet connection using 'sudo pppconfig'. (a) My connection doesn't need a username or password but pppconfig requires some input for these so I simply inserted the word 'blank' for both. (b) I specified ttyUSB0 as the modem port. (c) After writing the configuration files and exiting, edit the /etc/chatscripts/provider file to insert line: OK 'AT+CGDCONT=1,"IP",""' Here is my /etc/chatscripts/provider file as an example: # This chatfile was generated by pppconfig 2.3.18. # Please do not delete any of the comments. Pppconfig needs them. # # ispauth PAP # abortstring ABORT BUSY ABORT 'NO CARRIER' ABORT VOICE ABORT 'NO DIALTONE' ABORT 'NO DIAL TONE' ABORT 'NO ANSWER' ABORT DELAYED # modeminit '' ATZ # ispnumber OK 'AT+CGDCONT=1,"IP","preconnect"' OK-AT-OK "ATDT*99#" # ispconnect CONNECT \d\c # prelogin # ispname # isppassword # postlogin # end of pppconfig stuff 3. Connect with 'sudo pon' and disconnect with 'sudo poff'. Whilst I have found this solution works well, my modem is still not recognised by network manager (? a separate issue). However I have found that a connection is achieved faster using 'pon' than is usual with network manager. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991680 Title: [SOLVED]Huawei E220 and E1550 can't connect on Ubuntu 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-modeswitch/+bug/991680/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Why is this bug tagged as "solved"? Which is the solution? I cannot use my Huawei e220 modem but just sometimes (when it wants to work) With ubuntu 10.04 no problem. Upgrading to 11.10 o 12.04 breaks the recognizing of the modem I've tried the "solutions" proposed in other thread: 1) sudo usb_modeswitch -v 0x12d1 -p 1003 -V 0x12d1 -P 1003 -R 2) sudo echo "AT^U2DIAG=0" >> /dev/ttyUSB1 3) modify the /lib/udev/rules.d/40-usb_modeswitch.rules file 4) downgrade modemmanager to 0.4 version None of them worked for me. Some times the modem is recognized and many many times not. It's really annoying.
