Q: My mac osx 10.7.5 will connect using ethernet but not wifi. Another computer in the house can connect to wifi. Please help!

HI there,

I have been trying for the last two hours to repair my Mac osx10.7.5 wifi connection with no luck!

I just plugged my mac in directly to the modem and internet works perfectly. My mac says I'm connected to wifi but won't load anything. Was working perfectly last night. If someone could please offer any insight that would be amazing!!
