[Dell Latitude 6430u] 413c:819b 3G modem is not working

[Po-Hsu Lin]

CID: 201208-11537 Dell Latitude 6430u

There is a SIM card slot on this system, however, there is no such option for it to connect to 3G network in the Network Manager

But there is one extra non-working Ethernet device in it, "Novatel Wireless HSPA" [413c:819b]

I guess maybe it's for the 3G modem, but was incorrectly detected.

Three devices detected by udev and Network Manager:

Verified with 12.04.2 + v3.10-rc7 on 201208-11537
The modem is now available in Network manager, and the 3G network is working.

By the way, I can't connect to 3G network easily, I have to retry 3 or 4 times to get it connected.

[penalvch (penalvch)]

Po-Hsu Lin, as per your https://launchpadlibrarian.net/143527660/BootDmesg.txt :
[ 0.502870] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored

Hence, as per http://www.dell.com/support/drivers/us/en/19/Product/latitude-6430u-ultrabook an update is available for your BIOS (A06). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and just provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

[Po-Hsu Lin (cypressyew)]

Hello Christopher,

As this 3G modem could work with newer kenel, and the error message you pointed out is a "Firmware Bug",
I don't think this will be BIOS, related.

Thanks

[Po-Hsu Lin (cypressyew)]

Verified with 12.04.3 (3.8 kernel) this bug does not exist in stock image.
Verified with 12.04.2 + update (3.5.0-54) it works!

Therefore I will mark this bug as Fix-released

Please feel free to open a new one if you're still experiencing this kind of issue.
