unable to access network with wifi

Dear sir,

I'm using MBP with Retina 14" and OS X 10.9.1 (13B3116)

I can connect to my wifi and using the internet without problem but after about 30 mins to 2 hours, I cannot access the internet anymore and can't ping to my router (the wifi connection is also established, not disconnected or rejoin). When I open console and see wifi.log, I found this error show every time before problem occured.

Sun Feb 16 14:51:48.488 <airportd[86]> _handleLinkEvent: Unable to process link event, op mode request returned -3903 (Operation not supported)

Now, when I faced that problem, I have to turn off my airport and reconnect.

Please help.

Thanks
