Huawei E169 disconnects randomly

Post by Rosika » Fri Feb 22, 2019 2:26 pm

Hello,

I so much hope you can help me with my problem.

My system is: Linux/Lubuntu 16.04.5 LTS, 64 bit.
My umts-stick, according to "lsusb | grep -i huawei" is: Bus 001 Device 024: ID 12d1:1001 Huawei Technologies Co., Ltd. E169/E620/E800 HSDPA Modem

Every now and then it happens that my umts-stick disconnects all by itself. It not only cuts the connection to the umts-provider but disconnects from the system and immediately after that gets connected again.

Usb-modeswitch and usb-modeswitch-data are installed. I did that following the instructions on https://wiki.ubuntuusers.de/USB_ModeSwitch/ .

Sometimes I can use my umts-stick for a week without problems. At other times it gets disconnected every other day.

Perhaps the logs can give a clue as to what´s going on.
The entries that strike me as suspicious are: lines containing "Modem hangup" and "usb_wwan_indat_callback: resubmit read urb failed".

Re: Huawei E169 disconnects randomly

Post by Josh » Tue Feb 26, 2019 2:21 pm

First, I have to ask if there are any signs of trouble in the log before that "Modem hangup" line.

It's important to know if the modem is still connected to the system or if there is a "disconnect" on the USB level - which could indicate either a loose electrical connection (I have that on one laptop socket) or an issue with insufficient power supply which may cause the modem to reset.

If there is no indication of any problems ahead of the "Modem hangup" whatsoever, there may be an issue with the provider ending the connection or with the modem itself (faulty firmware, overheating or other).

Re: Huawei E169 disconnects randomly

Post by Rosika » Tue May 14, 2019 3:46 pm

Hello Josh,

thank you very much for you answer and excuse me for my very belated reply.
The thing is: I didn´t get any notice saying there´s an answer available. Sorry about that.

To answer your question:

Code: Select all

First, I have to ask if there are any signs of trouble in the log before that "Modem hangup" line.
I think not. Yet it´s not possible for me to look into those logs, because in the meantime I performed a fresh-/clean-install. I´m on bionic now (18.04.2 LTS, 64 bit). This is due to the fact that xenial reached EOL and thus I had to either upgrade or perform a clean-install of bionic. I opted for the latter.

Ever since I´ve been using my new system things became much better. My web-stick hardly ever disconnects now.
I really don´t know whether those two circumstances are interconnected......
But it´s really better now.

Plus: I have re-arranged my hardware setup a bit.
Perhaps I had too many devices connected to a single hub (albeit with power-supply of its own). So my new arrangement provides me with the choice of either connecting to a wlan-stick or to the Huawei umts-stick separately.

If I encounter more problems in the future I take the liberty of contacting you again, if you don´t mind. :wink:

So thank you again and have a nice day.

Rosika :)
