I have a NetGear WNA3100M(v1) Wireless-N 300 adapter, and it sort of works. That is, the speed annoyingly often drops down to just a few Mbit/s.
I find if I disconnect from my connection, unplug the N-300, plug it back in again, and wait for my computer to reconnect, the speed usually goes back to normal, which I know to be 30-40 Mbit/s.
Should I however unmount the USB adapter before I plug it out? It does not turn up as a USB drive in the file manager, so I can not right click it and choose unmount. On the other hand, it does turn up in the system tray in Windows 10, and from there I can safely eject it, before unplugging it.
I know Ubuntu is not Windows, and all that, but since I unplug the adapter quite often, it's important to know if I need to unmount it to prevent it from becoming corrupt, as in the case of USB memory sticks.
I'm also asking how to unmount it, if I need to do that from the terminal, since it's nowhere to be seen in the GUI - the system tray or file manager. I have searched this forum (related questions and more) as well as googling, but couldn't find a clear and cut procedure on how to do this.
