OS X Lion = NO internet connection

We have had the same issue. There are a lot of other threads out there on how to fix this but only one has worked so far and it was a temporary fix. I'm back to no connectivity on my MacBook pro. My 2 iPads and both pcs have no issue with the connection. It is definitely an OS Lion issue.

The issue may be your router may be running older firmware. Check the router's firmware using the manufacturers instructions and update it if needed.

I've been using a (Cisco) Linksys WRT165N V2 wireless router and after upgrading my Macs to Lion I started having issues. I just upgraded the Linksys firmware from 2010 and no change. If I take off the WEP it works fine but my house mates Dell wants to configure it with WPA2 that I can't access. If she skips the configuring she can still get right on unless the Dell is restarted. I'll probably either wait for a possible more current firmware upgrade from Cisco or invest in an Apple Aiport Express.

This may not pertain to your situation, but Lion currently lacks 802.1X compatibility, and thus drops connections to some networks that use that. I'm not a pro in that field, but I know that that is one issue with Lion, as it affects me at my school.

Hopefully in the next Lion update, Apple will address this issue. Until then, all we can do is wait.

If you decide to go with the Airport Expess I think you will be pretty pleased. I have both an Airport Extreme (2009 model) and Airport Express (also 2009) that both work wonders. Never had any issues with either of them.

This is 100% totally incorrect information. While there are some that having issues with Lion and their Wi-Fi networks there are millions (like myself) that are not. I've used my iMac and MacBook Air on a variety of Wi-Fi networks both are currently using Lion 10.7.2 and neither machine has had any issues. The current router I'm on is a DLink model again with no problems. The routers at my home are an Airport Extreme & Airport Express, both work computers and routers work flawlessly.

My first router was the Airport Express and I did enjoy the ease of the set up and also the audio streaming feature but it went bad. I'm in a small town with a Super Walmart and not much else so the easiest and cheapest option at the time was to pick up the Linksys.

Apple sells refurbished (highly recommend) AEX's for $69, click here.

Thanks for the info!

I have the same problem on an i3 21" 2010 iMac. My new MBA running Lion connects perfectly but when I "upgraded" my iMac the internet connection bacame so slow that I couldn't even open nytimes.com... My wireless router is an Airport Express.

Reinstalled Snow Leopard from time machine and is waiting for a refund or Apple fixing this.

Good luck to you all.

Your welcome.
