The laptop i'm using is an Acer Ferrari F0200 running on windows 7. It does not have wireless wifi link built into it. So i bought a wireless adapter: Aztech Wireless-N USB 2.0 adaptor(wireless-N WL552USB). I can't install it since the laptop doesn't have a DVD driver but just from plugging in, it is able to find a few secured network.
However, the particular network which i'm looking for pops out for a few seconds and then disappear. Even after connecting, I can't access the internet. Need some help here, thanks.
