Ethernet fine, airport not, settings look fine

I can usually sort out problems like this, but this time I'm beat. I have connectivity, full strength. I have an IP address but no web, email or ftp access. TCP/IP looks good and I've renewed the DHCP lease numerous times. DNS looks good, no proxies enabled. The computer is visible on the router interface. Ethernet is working fine. I've run maintenance scripts and verified preferences.
Any ideas? Which preference files relate specifically to airport functions? Maybe those are corrupt. I've checked support documents relating to WiFi but nothing looks out of line to me.
I have 2 wireless networks running with other computers, playstation, iphone and 3 androids in the family all online, but the MacBook Pro isn't working on either of them.
The computer has been performing flawlessly until now. What else should I be checking?
Many thanks,
Dave

Nevermind, the mac's been trouble-free so long I'd forgotten the basic troubleshooting step of creating a new acct, and that works fine, so we're on track here. Cheers.

Extreme Network Problem - Ethernet versus Airport

I will try to make this problem/question simple.
I have a home network with various computers around the house. I have an Ethernet switch in the closet, and various nodes running throughout the house to various rooms.
Also attached to my switch is a Time Capsule, which is used to create a wireless network and distribute DHCP addresses to other wireless computers in the house.
I also have an Airport Extreme in my home office that is configured, via Airport Utility, to extend the Time Capsule network, and is on the home network wirelessly. In other words, the Extreme is not hard-wired to the network with an Ethernet cable.
I have two Ethernet printers connected to the Extreme in my home office (by Ethernet cable), which I wish to use as network printers throughout the house.
In my home office, my iMac is hard wired to Ethernet, but also has the capability for an airport connection. I prefer, of course, to use the Ethernet, for speed reasons.
Here is my problem/question: In my home office, I can only print to the two Ethernet printers connected to the Extreme if my iMac is on the home network via its Airport setting (in other words, Airport is above Ethernet in the network connections order). In that case, the printers print fine.
If, however, I switch the iMac’s network connection to Ethernet (by setting the service order to put Ethernet above Airport), I cannot print to the two Ethernet printers connected to the Extreme - I get caught in the “attempting to connect to host...” mode.
First question: Why is this? The Ethernet and Airport network settings appear the same, except for the computer’s IP address (i.e., the subnet and router addresses are the same on Ethernet as on Airport). Seems to me that if the printers are on the network, they are on the network.
Second question: Even if I am on Ethernet (and therefore cannot print to the printers attached to the Extreme), the two printers attached to the Extreme do show up in the Print & Fax window. In other words, I can select them and add them as printers, but I just can’t then print to them.
What am I missing here? Shouldn’t I be able to print from the iMac when it is on the network via Ethernet? If not, why not?
I can always, of course (I guess), attach the Extreme to the network via an Ethernet cable from its WAN port to avoid the problem. But that would require running a LONG Ethernet cable, drilling holes in the top of my desk and bottom of a bookcase, etc., and I don’t wish to do that.
Any help would be appreciated. Thanks..

Yes, it’s Verizon FiOS coming into the modem, the modem to the switch. Make and model unknown, but don’t see how that would be an issue here.
I am trying to ascertain, whether or not, your entire network is on the same subnet. If you are using an Ethernet switch and not an Internet router (with a built-in Ethernet switch) directly connected to the modem, then your basic network will not work ... as the modem is only expecting a single device to be connected to it.
If you had the TC directly connected to the modem, and then, the Ethernet switch connected to one of the TC's LAN ports to provide additional network nodes throughout the house this would be workable.

Everything on my 4gs works fine, but the ringtone suddenly is silent on in calls. has been ok until recently. All settings "look" ok. Am I missing something in the settings?

IMac connects via ethernet fine but iBook doesn't get the wifi connection

I'm not computer literate. I'm told this has to do with the airport sharing but it looks to me like the airport sharing has to do with reading OTHER wifi connections on my iMac. I don't need that. The iMac is connected to the internet just fine. My iBook and my iPhone don't get the wifi connection that it used to get and I can't figure out why not. Thanks in advance for any and all help.

Welcome to the Apple Discussions!
More information would be helpful. Your iMac is connected to your ISP's service with Ethernet? And you are sharing that internet connection for the iMac with other Apple devices from the iMac's AirPort card? Do I have that correct?
If so have you shared that internet connection according to Apple's protocol for doing so?
My Mac mini is connected to the internet by Ethernet cable to my ISP's gateway. I am sharing the Ethernet connection to two iPod Touches via AirPort from my Mac mini. This is how Apple says to configure a Mac to share the connection;
1. In Sys Prefs/Sharing highlight Internet Sharing (do not check the box)
2. Share the connection from: Ethernet (from the dropdown menu)
3. To computers using: AirPort (check the little box)
4. Press the button AirPort Options...
5. Name the Network
6. Use Automatic for the channel or assign a specific channel
7. Encrypt the network with one of the choices
8. For sharing with a non-Apple device; PC laptop, MP3 player, etc, you must use only a 5 alphanumeric character, 40-bit WEP password or only a 13 alphanumeric character 128-bit WEP password. That does not apply if you are setting up sharing for Apple devices only.
9. Press OK
10. Check the box for Internet Sharing
11. Answer any dialog boxes that pop up
Any other forms of configuring sharing the ethernet over AirPort ususally results in various issues.

Ethernet active but not working - Airport works perfect

Dear all,
I have a very strange problem with my iMac.
One hour ago internet was working perfectly while being connected via ethernet cable.
Now it does not anymore.
General Settings - Network
The led of the ethernet is green when IPv4 configured manually - but internet does NOT work!!!
The led of the ethernet is green when IPv4 configured DHCP - and internet works!!!
In both settings then only thing that changes is the IP address, i.e.:
Manually I have to configure it as 192.168.1.21
With DHCP the IP is 192.168.1.160
I have read lots of discussions and tried the following:
Tested cable with LAN tester - fine
Tested switch / router / other computers connectivity via ethernet - fine
Tested connectivity on my computer using Airport and it works fine
Reset the SMC
Set service order Ethernet (top), then Wi-Fi
Launched terminal command netstat with following result
Name Mtu   Network       Address            Ipkts Ierrs    Opkts Oerrs Coll
en0   1500 <Link#4>    34:15:9e:36:b6:16     1040     0     7489     0     0

Please HELP!!!

Yes I can and I've done it.
But it is when I do that, Internet stops working.
I checked IP, subnet, gateway, DNS... all is correct but internet does not work, although the "led" into ethernet connection of the network settings is green!

Airport: Not Configured after 10.4.7 update

I just bought a new macbook 2.0Ghz, proceeded through the first-time installation wizard setup my wifi settings, and everything worked fine.
At first boot in macosx i had my wifi working and i was able to browse and download things.
I installed the 10.4.7 macosx update, restarted, then lost my wifi connection.
The signal indicator reads
Airport: Not Configured
and in the network settings under 'Network Port Configuration' I see a greyed out 'AirPort' configuration. I can"t enable it. I can't add a new one either since the only choices are Bluetooth, Builtin firewire/ethernet, 6 to 4
I found a knowledge base article describing a similar problem:
http://docs.info.apple.com/article.html?artnum=303437
But the described workaround doesn't seem to work.
I also tried to reinstall the 10.4.7 update using the combo installer, the issues remain.
I ran also the permission repair utility at various stages in the process, it never detected any errors.
In the System Profiler under network/Airport section, i see:
Airport Card Information:
Type: AirPort Extreme [..]
Locale: Worldwide
Firwmare: 0.1.24
Current Wireless Network: AirPort is currently turned off
I know the card is there and working, since linux happily uses it when i boot in linux.
Has anyone any clue about what's happening ?
Is there a simple 'enable' button somewhere, or is that a known isse with 10.4.7 updater, how can i revert to 10.4.6 then ?
Thanks a lot!
Macbook Mac OS X (10.4.7)

It's actually a bit more weird:
When stepping through the first-time boot wizard, it asks to select the wifi essid from a list, the scan is ok and shows my network, and i type the WEP key in the box, click next. The 'Configuring your computer' blinks then the setup goes on and asks for my .Mac account and so on.
After the wizard completes i'm able to surf the web and connected BUT !
The signal meter is always empty and clicking on it states 'Airport: Not Configured'. When i open the network preferences it says under 'current status' that i'm using the builtin ethernet device ??!!
The IP and dhcp re-lease stuff work in the UI even if it's clearly not the builtin ethernet card that i'm using since the IP is from the wifi router, and there is no cable plugged in, and i can access the internet.
No mention of Airport port in the setup, so i can't configure it.
As soon as i restart the connection is gone, and the setup created by the first-time wizard is gone.
So the situation is now i have a 10.4.6 os with no airport..

PS3 error: "An Ethernet cable is not connected" with E2000

Problem: My PS3 displays An Ethernet cable is not connected almost immediately after logging in. I am connected through a Linksys E2000 router. If I reset the cable modem, it will work for 10-15 minutes until it errors out again. If I plug the PS3 directly into the cable modem, it works fine. I'm really confused.
1. I do not believe it is the router, as my computer is also connected to the router, and works fine. My Touchpad is connected wirelessly and also works fine.
2. I do not believe it is the PS3, because it works fine if I plug it directly into the cable modem. I tried switching to wireless and it finds a lot of other signals (including mine), but I have the same problem if I choose wireless.
I first had this problem with a launch PS3 and a Netgear router after almost three years of no problems. This was back in November 2010. I replaced it with a Linksys E2000 router in January 2011, and a slim PS3 in late September 2011.
I had no problems from January until last weekend. I have tried to do the DMZ trick, but no luck. I have also tried to set the primary and secondary DNS to 4.2.2.1.
Does anyone have any insight? If I need to buy a new router, I will, but I don't understand because it works for my computer and Touchpad. Is it something crazy like when November comes, my internet settings get corrupted?

Try using the DHCP reservation feature to give your PS3 a "static " ip outside of the DHCP server range. So something above the range called "IP Address Range". 192.168.1.150 should be good, but you can check to confirm that this address isn't in that range.
Make sure your PS3 is set to obtain the network information automatically, NOT through a custom setting. Also, make sure your PS3 is turned off completely before doing this.
Could you also give us a screenshot of the "signals" tab when you go to 192.168.100.1?
I don't work for Cisco. I'm just here to help.

Which one can I use properly to monitor all the wireless Devices in my hous

Actually, none of the options will do what you are looking for it to do. That is because, this application only monitors the traffic from the device it is hosted on. That would also mean that you would have to run a copy on each computer that will access the Internet on your network; note their individual usages, and then, combine them to get an idea of the total usage.
However, if you are only interested in the amount of Wi-Fi traffic that only your computer is seeing, then the "AirPort Network Card" option would be the correct choice.

Sharing my Ethernet with Airport

I live in a dorm and for some stupid reason they disable the wireless network in the rooms. So I've been having my own personal wireless network in my own room by sharing the ethernet through Airport so I can use my iPhone. It was great, I never shut it off. I'd take my laptop with me to places and then when I connect it to the ethernet cable back in my room, the internet sharing turns on automatically too.
But ever since I got back in January the internet sharing randomly turns off by itself. I didn't change a single setting or anything. And the weird thing is that the iBook still thinks it's sharing! Look at the screenshot http://img.photobucket.com/albums/v336/hmarafie77/problem.pnghere.
http://img.photobucket.com/albums/v336/hmarafie77/problem2.pngThis is what it looks like before it turns off by itself. Once that little arrow is gone, there's no internet for my iPhone.
I don't remember if there was an Apple update between early December and January. But if there was, could it have had any effect on this issue or changed some settings or whatever?
Thanks.

You're right, I should have had only Airport checked and share my connection through ethernet.
The way I connect my iPhone to my Airport WiFi is by going to Airport Options in that same Internet Sharing window and that's where you create a network. Pick a name and password and then start the internet sharing. Your iPhone should pick up on that network you created, just enter the password and you're connected.
Thanks for pointing out my error!

Airport not Reconnecting after waking from sleep

Hi all,
I have a problem with Airport not automatically reconnecting after the computer wakes from sleep or is turned on or rebooted. I have it set to join a specific network automatically. Any idea why this may be? It used to work just fine.

I had this problem just recently and seem to have fixed it today. I made the following changes:
I changed security from WPA2 to WPA using the Airport Admin Utility.
I went to the Network Preferences panel and found that the network was still listed as WPA2, so I deleted it.
I then added the WPA network to my preferred network list.
The computer now reconnects automatically after sleep or shutdown.
I don't know whether changing from WPA2 to WPA was necessary. It may be that all you need to do is delete and re-add the network.
Hope that helps!

10.5.7 sleep issues, I don't have ethernet, that's not the problem

I'm not that computer savvy so please simplify your answers and solutions to my problem. I know that my problems have to do with 10.5.7 because they started after I downloaded the update. My computer needs to be rebooted every other time I shut the lid to let it sleep because it won't go into sleep mode. I've done the thing where I hold down control, command, p and r (or whatever it is, I did it right). I fixed my airport so that it would disconnect whenever my computer goes to sleep (I don't use ethernet, that's not the problem). What other solution is there to this problem? How can I remove the update? Please only offer new suggestions, not the two above that I already tried. Hopefully someone can explain this to me in a way I can understand and give some good suggestions. Thanks in advance.

Before I move on to the more complicated suggestion, I wanted to ask about Disk Repair. I opened up the Disk Repair and I verified the hard drive and there weren't any problems.
You mean Disk Utility (in your Applications/Utilities folder)? Did you run the +Verify Disk+ (not permissions) option, or did you look at the bottom where it says *S.M.A.R.T. status: Verified?*
If you didn't run +Verify Disk,+ do that first. If it finds errors, you'll have to boot from your Leopard Install disc to repair them (you can't repair the disk you're running from). Post back if you need to do this but don't know how.
But when I tried to verify the permissions it said there was less than one minute left and the little status bar didn't move past half way so eventually I just had to stop the verifications.
Assuming you ran +Verify Disk+ and it showed no problems, how long did you let +Verify Permissions+ run? It does take quite a while on Leopard; 20 minutes or more, depending on your Mac, how much is on it, etc.
By the way, it's a waste of time to run +Verify Permissions.+ Run +Repair Permissions+ instead.
Can you also sort of simplify the second suggestion about the combo update?
This is a combination (thus the clever name) of all the updates to Leopard since it was first released. Installing it should fix anything that went wrong with any previous "point" update. Download and info are at: http://support.apple.com/downloads/MacOS_X_10_5_7_ComboUpdate
Once it's downloaded, back-up your Mac if you can, then:
1. Disconnect everything except your Keyboard and mouse.
2. Repair permissions if you didn't above.
3. Double-click the downloaded file to install it.
4. After your Mac reboots normally, run Repair Permissions again.

Ethernet and Airport Interfaces Reversed

I created an image of the new Mac Book Pro(Mid 2010) and slapped it on the new Mac Mini(Mid 2010) and everything worked fine except one thing. I used the DVD that came with the Mac Book Pro(Mid 2010) to create the Master Image.
Under Network Preferences, the Ethernet Interface is displaying the Airport status window(i.e, "Turn Airport On/Off" button is in there). And the Airport Interface is displaying the Ethernet stats.
Any ideas what could be causing this?
Message was edited by: jjpotter

I had the same problem (reversed Ethernet and Airport interfaces) on my 13" MacBook Air after plugging in my Thunderbolt Display. The solution was to go to Network in System Preferences, click the minus symbol under interfaces to delete both of them, click plus to add each one back, then click Apply. Now everything is as it should be.

10.5.6 - Network System Preferences confuses Ethernet and Airport

Since upgrading to 10.5.6 I'm having odd behavior from Airport (which is the only network connection I typically use). Symptoms include Airport turning off when the MacBook wakes from sleep, and Airport not automatically connecting to my home network (to which it regularly reconnected prior to 10.5.6).
The strangest symptom, however, is how Ethernet and Airport are mixed-up in the Network preference pane. I can't post a screen shot (hey Apple - why not?!) so I'll describe:
* In the list of Services on the left side, the service named "Ethernet" has an Airport icon, and the service named "AirPort" has an Ethernet icon.
* When Airport connects, a green dot appears next to the service named "Ethernet".
* When I select the service named "Ethernet" (with the AirPort icon) I see options to the right mostly related to AirPort. Thus, it looks like the Network pref pane has become confused about the names of the services... BUT when I rename the services to correct, then restart the computer, the names go back to the mixed-up situation described above.
Any ideas of how to fix?

Or somebody's playing a prank on him.
AirPort does turn itself off when the computer is asleep. It takes a few seconds for AirPort to reconnect. If the WiFi signal is weak or if there are a lot of network noise, AirPort may not reconnect for a long time.

I cannot add a Wi-Fi guest network. Gone to Utilities Airport Utilities and all get is an image/browser of my Airport Extreme. Looking for the browser which has the title Wireless but cannot find anywhere. I need help?

I cannot add a Wi-Fi guest network. Gone to Utilities>Airport Utilities and all I get is an image/browser of my Airport Extreme. Looking for the browser window which has the title Wireless but cannot find anywhere. What am I doing wrong?

Open AirPort Utility. The first screen looks something like this:
Click on the AirPort Extreme and another screen will appear. Click Edit, then the window with the Wireless tab will appear.
If you do not see these screens, you will need to start over and configure your AirPort again.
