My very old laptop has informed me one day that he can no longer be connected to the Internet. The WiFi card made no longer with. Although I have a different built-in, the connection failed to materialize. So I bought the stick. The part inserted into USB slot and voila! There is again the internet. Biggest advantage - look small, so that it can remain permanently in the slot. This is also a disadvantage. The antenna is very small and thus receiving weak. But at home, it is enough perfectly!
