WWAN card DW5811E in E7450?

Hi. Anyone got this card to work in E7450? Notebook cannot see this card on any bus... Any low level checks I can do? Maybe some specific BIOS version?

 

The DW5811E card uses the PCIe interface. A clue is here which states that the DW5809E (compatible with the E7450) "PCI Express card M.2 Form factor (Not standard PCI Express) ".

This suggests that while the E7450 has what looks like an M.2 PCIe slot, it isn't configured as PCIe and consequently doesn't recognise the newer WWAN card. More likely to save a few cents on manufacture than deliberate incompatibility.

Hi,

Thanks for this information, based on this I returned 5811e and got 5809e. It works out of the box with my simcard, however... I'have got this:

Dell Wireless 5809e Gobi(TM) HSPA+ Mobile Broadband Card USB\VID_413C&PID_81B3&MI_0C

and not this:

Dell Wireless 5809e Gobi(TM) 4G LTE Mobile Broadband Card USB\VID_413C&PID_81B1&MI_0C


Do you know if:
- can I reflash it somehow to LTE, or the chips are totally different inside?
- change VID/PID if chip is the same?
- how to distinguish between those versions by reading the label?

What I discovered, they are selled with 3 flavours: K2W44, 52NX8 and 8GHFY. I suspect I need K2W44, sold widely on ebay and not 52NX8 which I have now.
I tried to change driver by force, but on Windows 10 it reverts back to the previous one, and of course no LTE connection (only HSPA+).
