Thanks for your help, well my operating system is windows 10, a week ago, the divice was dropping the signal every single minute, it´s very weird because right now it´s working normally, but sometimes it just stop working, the distance between the router and my pc is about four meters and a half i guess. it has a strong signal, to make it work again i have to unnistall the drive, install again, sometimes with just changing the usb port, or restart my router, in other cases it just come back to work randomly without do nothing, in other devices sometimes the signal drops but when they catch the signal once the signal appears, all goes normally again, it happens seldomly, i´m starting to suspect thay maybe my internet service is having faults, but it´s really strange that it do work sometimes and  sometimes not, i don´t really know who the problem is with 

First i used the official page Drivers, i tried with three versions, but the V3 seems to be the correct, after the problems, i tried using the CD, but it was the same 

@Kevin_Z I have the same problem. It begin around one year ago (so about time of that post with one of Windows 10 updates).

Basically it's not connection problem. Dongle randomly dissapears from devices and putting it out and in helps.. for 5 minutes. It's extremaly annoying. I used Linux for some times and now I'm back at Windows and I see you still didn't fix drivers. Shame on you. Never will buy again hardware made by you.

@Emme_Strt I have the same problem, when i bought it it worked great for first week and after that it start constantly dropping after +- 30 seconds
