Connection Problem

[Aspire]

I use a wi-fi connection with a wa3002 g1 model from starcom.
Sometimes i get this message and connection fails, i need to replug my wi-fi device to get a connection

Can someone tell why?

I'm able to connect the two PCs like in LAN, but i cant like access net or play online until i repair the connection OR Replug the Adapter

Yeah it is common problem in a WI-FI i too get these error messages when connection is low, but i never replug it, it reconnects after automatically.
