I fixed the problem, im not sure if this was the cause, but lemme show what i did:
So at the start, please look at this picture:
The way those 2 slots are populated is not natural- what i mean is that at the beggining i only had the wan card and one slot was free. But, before installing the usb dongle with its card i had to move the wan card from wan slot to sataflash slot and insert the usb dongle into wan slot. Why? See the place i circles (squared?) with red color. This metal border was to close and the dongle was to long so it wouldnt fit.
This way it was buggish and when i turned the switch my mouse wasnt working instead of wireless...
What i did to fix this problem:
I ripped off some of the metal borded using sharp pliers and replaced the cards to the proper slots (wan card in wan slot, usbdongle in sataflash slot).
Everything seems to be working so far.
