Long time lurker, first time poster. I know that the MBA has some known issues with WiFi but mine seems to be different. I have a 2010 13" with 4GB ram running Lion. Sometimes, when I am browsing the web, my internet will just stop working but I am still connected to the network. The only thing my computer will do is sit there and attempt to load the page (normally a white screen). My girlfriend has a 2011 MBA and it never has this issue, nor do I have an issue using WiFi on my phone and connecting to a website when a webpage will not load on my MacBook. Does anyone have any ideas? I have searched and searched but have found nothing that matches my issue.
