iMac using Wifi won't connect to internet!?

[abillybob]

Hey Guys

 

So for some odd reason we have a couple of iMacs and they aren't connecting to the internet. They're connected to our wifi network and receiving a correct IP address served by the DHCP server. The macs aren't connected too the domain in anyway and are using local generic accounts for the students. They also have the correct proxy settings in...

 

Can't seem to ping smooth wall server either!?

 

Any help would be most appreciated

I had this with an iMac a couple of weeks ago. I couldn't figure it out so as a last resort I deleted the WiFi Connection in the Network area and re-added it. This fixed it for me.

Weird... Cheers I wouldn't have thought this would make a difference!! I'm guessing this is a temporary fix though and that it could happen again, does anyone know of a more permanent fix?

Did it work for you?

It's not happened again for me (yet).
