On Monday I upgraded my Mac to the new Operating System dubbed ‘Snow Leopard’. At £29 there’s really no reason not to. I installed it as an upgrade, only took just under an hour, with not issues and by the looks of things no data loss. However on connecting to the internet I noticed the response was really, REALLY slow.
After routing around, I decided to put the firewall on, and turn it off again to see if that would make a different. Much to my dismay, that resulted in the Wifi connection being completely lost. The strange thing was, I could still connect to my router, but could not access any web pages.
When I googled some more (on another computer) I came across a post which outlined that for some reason the DNS had changed. So I changed it back to the DNS for the router and success it worked.
So all you need to do is:
1. Go to; System Preferences -> Network -> Advanced (on Airport) -> DNS
2. Add your router’s IP to the DNS Servers section.
This should fix the problem that took me aages to figure out. Hope that’s helpful for anyone, not entirely sure why the DNS settings would have been messed with but I guess those it reverts back to the factory settings.
This fixed my issue. Thank you so much!!!!
