AT&T Beam / Aircard 340U not recognized by Ultrabook PC (Windows 10)
MY 340U is not recognized by my machine when inserted. It appears as though it is stuck in some kind of constant restart loop - The AT&T logo will appear of its screen for a couple seconds, then go b...
zactly, Maybe this is just a matter of symantecs, but I don't feel like this is a "solution", but rather a "work-around".
If you had read my further posts on this thread, I already explored the "usb hub" work-around. While it is functional, and I use it in emergencies, it requires that I carry around yet another peice of hardware that I would much rather not have to carry with me.
So, I decided to get a usb 3.0 hub, with a built in ethernet port, since the XPS 15 does not have one of those either. At least now this extra hardware that I must carry with me servce more than one purpose.
Thanks for your reply to this thread.

Wstyle1, Can you describe the compatibility issues you experienced?
I'm interested in seeing if the 340U behaves the same way as it does in my Dell XPS 15.

I received some items from amazon today-time for some experiments...
First I tried a powered usb 3.0 hub: I plugged in the AC340U and my Dell PC recognized it and it works perfectly.
I then tried a USB cable that allows the user to plug a single usb device into two usb ports to pull more power: I plugged in the AC340U and the PC recognized it, but I could not get it to connect to the net. I think it still wasn't getting enough juice from the USB ports.
All this tells me that the AC340U is a power hungry little brat. It's probably a design flaw that cannot be fixed via firmware. However, at least I can still use it with the powered hub (a majorly inconvenient work-around) if I'm in a bind.
Maybe it's time to look for an unlocked Huawei device since it seems that Netgear (Sierra Wireless) will probably not be releasing any more LTE dongles.
Further experimentation:
I removed the power adapter from the usb hub and plugged it into my PC, then I plugged in the AC340U. It worked!!
Now I really am at a loss. There was no additional power being supplied at all. The only difference is that there was a 3 port hub in between the AC340U and my pc. Perhaps, the chipset in the hub is somehow fixing whatever mis communication is taking place between the AC340U and my PC?
I don't know. I'm stumped. At least now I don't have to cart that power brick around in my laptop bag. :)
