I have a Macbook Air I bought in November 2011, v 10.7.4 and I have issues connecting to the internet. Though the wifi symbol shows that I have a strong connection, I have no internet access. The only way to get it is to shut down my laptop, and reset my router by turning the power off and waiting for a bit then turning it back on. I know I don't have a problem with my router/internet access as other users in my flat have no trouble. Anyone have any idea what the trouble is?

Hi, I have a number of questions. 1. Did you ever have a wifi connection? If so, has something changed? 2. If you connect your computer through Ethernet, does that work? 3. If you take you computer to a Starbucks or equivalent, do you get wifi access? 4. Can you update your question with a screenshot of your internet connections? –  David DelMonte Jul 17 '12 at 19:56

Things to check:

  1. If you are using WIFI only, you need to set the Service Order and the first will be your WIFI.

From System Preferences > Network

enter image description here

Then Click "Set Service Order"

Drag and drop the WIFI connection to the top of the order list

  1. On your Network Settings > Wifi > Advanced > DNS, add your Router IP there.
