I bought my wireless adapter three days ago. It worked perfectly, until it started constantly disconnecting (every 1 or 2 minutes). I sometimes have to pull out the stick and put it back in more than five times until it starts working again. Also, even when it is connected it says no connections available. Or it shows an exclamation mark in a yellow triangle and I have to pull out the adapter again. It's impossible to browse for longer than three minutes.
