Hi Ainur,

Looks like your WiFi Wi2Wi module is fine. This the problem is with your company's firewall or gateway or proxy server.. I, once upon a time, had a similar problem and got it sorted out with my network admin.. They had a special access rule with the IP address that got assigned.

-->You can manually change/set your ip address and check if it works ("ifconfig wlan0 ip xx:xx:xx:xx" method, and also the correct gateway "ifconfig wlan0 gw", you may have to disable "NetworkManager" by using "pkill").
-->Or alternately connect to a Android phone's HotSpot and then try pinging, make sure your phone has internet access, either 3G, 4G or GPRS.
