wi-fi going on and off [SOLVED]

[agvares]

so, I face the following issue: pretty often my Wi Fi connection would stop working (nothing can be pinged also), and the only way to set it back to life is turn Wi Fi off and on after some seconds.

none of that happens on other computers, which share the same network.

any suggestions what that might be and how i'm supposed to get over?

solution: using Wcid rather than a default connection manager
