Dell Wireless 5570 - problem with linux.
Hi,
im fighting with run this modem (original name MC8805 from Sierra Wireless) under linux (Ubuntu 12.04), Kernel 3.11.7 with small modification - added ID product ID and vendor ID to the sierra.c driver and now i see the ttyUSB* devices corectly. But.
Modem starts in low power mode (forced by BIOS?) - flag triggered to 1:
at!pcinfo show:
State: LowPowerMode
LPM force flags - W_DISABLE:0, User:0, Temp:0, Volt:0
LPM force flags - BIOS:1, GOBIIM:0, IM_AttachDelay:0
W_DISABLE: 0
Poweroff mode: 0
LPM Persistent: 0
but i have on the same laptop Windows 7 - and when i first boot windows 7 system and do soft reboot and boot linux again the modem works:
State: Online
LPM force flags - W_DISABLE:0, User:0, Temp:0, Volt:0
LPM force flags - BIOS:0, GOBIIM:0, IM_AttachDelay:0
W_DISABLE: 0
Poweroff mode: 0
LPM Persistent: 0
So i think that windows driver sends some command/signal to modem for wake up? What it can be?
When the modem is in LowPowerMode when im trying to mage AT+CFUN=1 gives me error.
My laptop is Dell E7240. I have two latptops with this cards and problem is the same.
I updated the bios for the laptops to A06, problem exists still.

The Dell-branded Sierra Wireless modems can be brought out of the low-power mode using the "FCC Auth" QMI command (DMS service, 0x555F), supported now in libqmi and ModemManager git master. See:

If your modem is exposed as an MBIM device, try to switch it to USB configuration #1, which is likely the QMI configuration.

Same problem here with a Precision M4800 and BIOS A06
I'm on kernel 3.13.0-5 and get a wwan0 device
but can't use it either.

Another disappointed customer here. Running on 3.14.0 and people have not been able to figure out how to power it up. Spending nearly 2K on a Dell laptop with this E7440, I really expect some effort by Dell in getting us some information on how to get the card going.

Same problem with en e7240. I got this card 5570 to solve all my dongle problems.
Now I can see a wwan0 but not use it.

Has there been any update on this? I still cannot get the modem to work even with the new kernel 3.16. Can anyone at dell chime in on a solution?

I've replaced the Dell 5570 (a.k.a. Sierra Wireless MC8805) with a
Sierra Wireless MC7710.
The MC7710 has been working flawlessly out of the box under
Linux and Windows with my Dell Precision M4800

I switched mine with Dell 5530, the Ericsson F5321. Also works fine.
