Linux Mint Forums

I'm very new to Linux Mint 13, before I used the "Katya" version though. I've an happy experience with the new Mint 13 Maya except one case, that I'm disconnected from internet always!

I use a Huawei 3G modem (E352) to connect to the internet. I didn't have to worry about usb-mode-switch because they're bundled with Mint. Well, my modem was detected and I made a new connection, my ISP Airtel was in the list. That was fine so far. But when I connect, it either disconnects instantly or after 10-15 seconds. And the modem disappears from network manager. If I reconnect the modem it appears again in network manager but on connection it disconnects and disappears. Strange!! Though lsusb always shows the modem no matter whether it is connected or disconnected or disappeared from network manager.

The same problem persists in Ubuntu 12.04 though. I tried at least 5 tricks but still it remained unsolved. Please help, my Mint is lying uselessly, because, you know, without a working internet a PC is almost useless in 3 parts out of 4.

I guess that the reason is a lack of current, so you could try to give some extra current using branch-USB-wire, which gives some extra current from USB-port.

But the modem works fine under windows. Is it really possible to have lack of current specifically under linux?

What's wrong there?

i didn't see something weird , maybe you can try put in different usb slot, or maybe you can try with your samsung galaxi fit ( cellphone :?:

) disconnect from usb port.

by **nacreous** on Thu Jun 07, 2012 3:09 am

i have the same problem, disconnected after several hours

my modem (via lsusb): Bus 003 Device 009: ID 12d1:140c Huawei Technologies Co., Ltd.

add:
i must unplug the modem first then plug it back to reconnect again because the modem disappear from network manager.

by **mank_in** on Sat Jun 09, 2012 9:43 pm

I don't think the modem lack of current. I am recently have problem like this too ( usb modem disconnectedly ).
Try :

Code: Select all: sudo service network-manager restart

I think recently update (network-manager) fix this problem for me.

@mank_in

still experienced the same (updated yesterday).
i dont think its the modem either, have read this kind of problem in LISA and its fixed.

this is from syslog, maybe tells something ^^

Kalau gitu pakai bahasa indonesia aja ya.
Telkom Flexi evdo sejak awal 2012 suka mengubah-ubah setting servernya ( saya pakai telkom flexy EVDO ) , coba ubah setingan pada network connection , pada mobile broadband ,ppp setting:
hilangkan centang pada allow deflate data compression

Nanti coba saya cek komputer satu lagi yang pakai LM13 MATE , komputer utama saya pakai linux mint 13 cinnamon

by **nacreous** on Sun Jun 10, 2012 3:12 am

iya saya dari Indonesia
is it okay to use Bahasa Indonesia? because im "trying so hard" to explain my problem in english XD
forgot to tell that this occurred both in MATE and Cinnamon

this is getting really annoying
i think this problem has similarity with this viewtopic.php?f=157&t=103159

Hi,
I had the same problem with a Huawei 173 USB modem.
The dmesg shows that your device was recognised and configured properly as a modem (/dev/ttyUSB0) with usbserial driver.
Run 'usb-devices' at the terminal prompt. you should see your modem, alongwith the various modes it supports. Output from my device is below:

T: Bus=01 Lev=01 Prnt=01 Port=05 Cnt=01 Dev#= 5 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs= 1
P: Vendor=12d1 ProdID=1436 Rev=00.00
S: Manufacturer=HUAWEI Technology
S: Product=HUAWEI Mobile
C: #Ifs= 7 Cfg#= 1 Atr=e0 MxPwr=500mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I: If#= 1 Alt= 0 #EPs= 1 Cls=02(commc) Sub=06 Prot=ff Driver=cdc_ether
I: If#= 2 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=cdc_ether
I: If#= 3 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I: If#= 4 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I: If#= 5 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage
I: If#= 6 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage

Note that the vendor and prodID are different in your case -- make a note of them. Also note the interface number for data ('2' in my case).

now run (in terminal)

sudo usb_modeswitch -v YOURVendorID -p YourProdID -R -i YourInterfaceNUMBER -n -s 3

You should see some text being displayed and your modem being reset. Now check your Networkmanager applet icon in the panel. You should see you mobile broadband connection again. If you use Edge predominantly, edit the connection properties to disable roaming ('Any network' checkbox) and set connection type to 2g/EDGE only.

if all works good, copy the last line of code (sudo ...... -s 3) and paste it into a text file , so that next time you just have to copy-paste it!

Happy surfing!
