I'm new to the Mac World.
I got a Macbook Pro and I'm having issues with internet connection.

I have set up the networks at pretty much all the locations I visit frequently. My Macbook shows the Networks under the Airport Icon. I have all the passwords saved on these networks as to automatically connect.

My problem is that why is it that at times I can not connect. Sometimes I can and sometimes I can't. When I can't, I would have to shut down and re-boot and that works sometimes. Other times it doesn't and I just wait to try it again later.

For instance... this happens at my home. I know it's not the internet connection because I have my other computer connected via ethernet and it works. I also have my xp laptop and it works wireless. It's just this Macbook Pro.

Any Suggestions?????

I have had a problem similar to this with my iPod touch, where if yells at me and says i cant connect....Are you sure you have a strong signal? That's the only solution I can think of.

My signal has full bars. I know that's not an issue.

What I noticed is that when I went to Network Settings... I saw that the AirPort light was green and said "Self-Assigned IP" underneath it.

Then on the "Status" it said it was "On" and underneath that, it said this:
"AirPort has a self-assigned IP address and may not be able to connect to the internet."

I'm not sure how or why this happens.

Can anyone explain and give me a fix for this?

Hi,

I had this same problem and after much discussion with Apple support, we reset my Airport and, instead of "Bridge" mode, tell it to share a public IP address. This is because my ethernet connection comes directly from the wall and is provided by my apartment management (i.e. I don't have my own modem). So, I don't know if this is the situation for the original poster, and his post was a while ago anyway, but in case someone else lands here like I did, here's what we did to fix my problem:

First, to check whether you're in Bridge mode:

-Go to Airport Utility.
-Go to Manual Setup.
-Go to the Internet symbol at the top.
-Under "Connection Sharing," you should have "Share a public IP address" (not "Off (Bridge Mode)").

If you are in Bridge Mode, then you have to reset your airport (the little button next to the audio port), go through the whole setup shebang again, and be sure NOT to select "Bridge Mode", but rather, select "Share Public IP Address."

Hope this helps someone.

I have the same problem but i cannot even enter manual setup because it cannot even find any airport wireless devices. My internet is working because my mini mac is connecting. My macbook pro connects to the wireless but after a short while it turns to an exclamation mark and says there is no connection.

Any tips would be great! I really need the internet on my laptop right now for work.

have you updated your airport via software update ?
if you did , then the problem is still appear
try to go to system pref > network > delete airport > close system pref > restart your mac > open system pref > network > add new airport ..

if you use your own wifi router not public router, try to reset the router, after that try to connect your mac again ..

Have you tried connecting via ethernet cable to your Airport then check for IPv4 config DHCP
this will give it an ip then you should be able to get on depending on the modem you may
have to disconnect the wan for 15 to 20 seconds then plug back in.

It will be in your Airport Utility and in system preferences under TCP/IP
Go to system pref >network>advanced>TCP/IP > connect (DHCP) might have
to hit renew ip.
Airport Utility >Manual setup >internet>TCP/IP >config IPv4 using DHCP also may have to click on renew DHCP lease. Sometimes after this you may have to reboot the AE.
