As I'm having super-low network speed with my ZTE MF90+ (pocket router) I wanted to try connecting with a Vodafone K3806-Z (internet stick) but I can't access any, I have 2 and when I plug them both nothing happens. I should be asked what to do when I plug anything as Removable Devices default settings (that I never changed). Only Disks shows them so they work and contain their software. Even my Momo Design MD-A doesn't work, I think that it misses of the internet software. I plugged all 3 to my laptop with Windows 7 Starter and they work, MomoDesign MD-A works only as mass memory device as it has a button to switch from network to mass memory function. How can fix to access to them?
The simple answer is these may not work with Linux. Just because they work on Windows they may only work on Windows and not Linux or Mac. It's irrelevant if it they work in Windows.
If you can see them that means the system sees them as files, and you need to go in and tell it to see it as a connection. Then you'll also need to install the driver for them. You may also need to install a driver/software for the company that is providing the service as well, I know Vodafone is big on this. But once again that may not be available for Linux. You will need to go the service provider website to see if they have a linux software for those devices.
My suggestion would be to buy a dongle that works with Linux where you slip in a sim card and bypass any provider software
Maybe you should buy a stick that does work with linux, here in our country they are around 20 euro's and work out of the box.
Bought this one last year for my wife because windows 10 update destroyed my wifes wifi card -> https://www.amazon.nl/TP-Link-3-0-adapter-netwerkadapter-Ondersteunt-T3U/dp/B07M69276N
Try this one .... I wrote a T & G about the one I use and it has been working just fine .... please note there are some dongles that support both WiFi & Bluetooth and some just WiFi ..... the one I have supports both .... choose the one you need ..... I also listed some places where you can get it ..... have a look
