Macbook pro 10.8.3- I'm having a problem with internet connection. It appears that the wifi connection is good but the internet drops out. Other computers on the network do not loose the connection, ipad, iphone, pc. I have tried to change security from WPS2-PSK to WPA-PSK, it worked for about 5 minutes then failed again. When it is bad I checked diagnostics under "assist me" Wifi, wifi settings, network settings are green; isp, internet, server indicators are red, after selecting network, and "continue" it turns it all green and says there is no problem, works for 5 minutes and fails again...grrr Ethernet connection works without issue. Thanks for looking at this.
