Hi, and thanks for using JustAnswer. Add this page to your Favorites/Bookmarks first, so as to get back to me anytime later on, if needed.
Are you on the MacBookAir now?
No, I'm on a MacBook.
It connects fine. The MacBook Air is the one that keeps giving me trouble.
Ok, great. Do you also have your Network Name and Password?
On the MacBook Air click on the Airport icon on the top menu bar and "Open Network Preferences"
Next, highlight any "Airport" device that you have in the left panel and "delete"
Ok, to the left of the "delete" you wlll see a "+", click on that and create an Airport Interface.
Ok. Just go ahead and name it "AirPort 2" as suggested?
Have you deleted all the Airport Interfaces?
Yep. I think, anyway. The left panel is blank.
Ok, great then proceed. Then use the assist to setup up the interface. Reply back if you get stuck with an unknown question.
Ok. Going through it now...
Ok. I made it to the end. It says "Unable to establish a network connection" and another little message.
Run the troublshooter
Ask me questions if your not sure what to select.
Ok, locations ... Automatic, yes?
versus "New Location"
Check to see if you have other locations
Use new location.
Automatic and New Location are only options
Ok. Now under "Choose the network port configuration ..." the only options I can click are Ethernet and Other. External Modem and AirPort cannot be clicked. However, AirPort is checked already
restarting router now
What make and model router do you have?
When you set up the Airport, did you see your WiFi network?
The setup assistant said it couldn't fix it.
What version OS X do you have on the MBA?
Go back to Network Preferences
Click on the gear to the right of the "-"
Select "Set Service Order"
Move Airport to the top of the list.
Ok. The only other thing was Bluetooth DUN. Just changed it.
Turn Airport off, then turn it back on.
Ok. It recognizes the network and gets all the bars, but in the menu it says the thing about the self-assigned IP Address
What happens when you open Safari?
And try to go to www.ibm.com
Is the Airport Icon greyed out?
Now it is, yes. With an ! in the middle.
Did you enter a static IP on this Mac at some time?
What's a static IP?
Have you tried to tether with a hotspot or 3g device with this Mac?
Only the wireless router that Time Warner gave me
Ok, click on the Airport icon and then click on "Advancced"
How many "Preferred Networks" so you see?
Just "tuba." That's the one I've been trying to connect to. That said, earlier tonight I deleted all the other ones that were stored there.
Delete that one with the "-" sign please.
Ok. It's empty now.
Then use the "+" sign to add a new network. Make sure you are using the correct sercurity (WEP, WPA, WPA2)
done. Now click OK?
It should try to connect.
Do I need to hit "apply"?
What is the status of the Airport icon now?
Same deal. Greyed-out AirPort icon with an exclamation point
AirPort has self assigned IP
Ok, go back to network preferences
in network preferences
Click on Advanced
Click on TCP/IP
Make sure the settings here are "Using DHCP" and "Automatically"
Comparing that screen with the equivalent on my macbook that I'm currently using. There is no router info on the Macbook Air
Ok, go to DNS and tell me what entries you have.
Everything is blank on DNS
go to Proxies and make sure all the boxes are UNchecked and then tell me what you see in the white space
All of the protocols are unchecked. At the bottom there is a checked box for "Use Passive FTP Mode (PASV).
The white space says ...
ok, good. Go to Ethernet and tell me what the settings are please.
Ethernet ID: 78:ca:39:3f:d6:5e
MTU: Standard (1500), but it can't be clicked
and that's it
Close that then open network preferences again.
Now try to connect to your WiFi.
it's trying ...
It may be that your router DHCP has been turned off. Have you checked that?
How do I check that?
Go to your Mac that's on your WiFi
Go to Network Preferences
It says it's "Using DHCP"
What is the IPv4 IP address you see?
Click on "Renew DHCP Lease"
Did it flash and comback?
Ok, I'm going to leave chat and do some research on this issue. I will reply back when I have a resolution.
Thank you for your patience.
Thank YOU, Richard
