Ethereal and TCPDUMP cause airport disconnects

While attempting to get packet captures of initial airport connectivity failures, any time I startup Ethereal (installed via forced Darwinport updates) my airport connectivity drops. Once I exit the interface capture menu, I can re-establish connectivity.
On initial startup, TCPDUMP also causes he airport connection to drop, but I can subsequently select "Other" and restart the connection while TCPDUMP is running.
I'm working from a Black Macbook, connecting to multiple Airport Expresses or an Airport Extreme basestation. Connectivity is setup to use WPA2 (personal) over 802.11G.
I also noticed during a capture session of the first 5 seconds after starting my airport, that 802.1x authentication is being attempted. I do not have 802.1x setup (it's not showing in my Internet Connect window). Is that part of the normal WPA or some other Apple specific connectivity??
How does one open a bug report if there's no application crash window to work with??
thanks...

I've resolved this! For some odd reason Apple won't let me denote this so I'm adding this reply. Turns out the problem was POWER related. The Airport was plugged into a power strip with several other devices. I unplugged all of those leaving just the Airport and the problem has not returned. If I add on all the devices, regardless of the power strip used, the problem returns. So it appears the Airport was just not getting enough power.
I've got it on a UPS now and the problem has not returned.

HT204291 I must continually disconnect and reconnect my airport express to get it to play my iTunes library on my TV. Why?

Why must I continually disconnect and reconnect my airport express in order to get it to play my ITunes library on my TV?

I have a HP Pavillion dv6000 running Windows Vista. Itunes is up to date. I have power cycled the router several times it is a Surfboard sbg6580. still no luck with seeing the airplay symbol on itunes, but Isee it on my phone and can stream music via the airport with my phone. I can see both airports on the airport utility on my laptop. I'm stumped...

ITunes 7.3.2 and security 1.0 updates cause Airport

Updated to iTunes 7.3.2 and installed security fix 1.0 Rebooted fine, but now my Appletv no longer appears in iTunes and neither does airport express network. Base station can not be detected in the Airport admin utility.
Everything was working fine before the update. The AppleTV is an Airport issue I guess.
Anyone have any ideas on whether its the security fix or itunes update thats causing this? Have tried reinstalling iTunes 7.3.1 but no change.
Thanks for reading

No, I hadn't tried creating a new user identity, but I just gave it a try. No luck. In fact, no calendar items at all would sync from that user identity (neither ones that I create nor ones--such as holidays--that Outlook adds itself). Furthermore, sync finishes very quickly, even if I import all of my "real" account's calendar items into the test account.
So, I assume something else is wrong relative to the test account, but I can't find it. I don't see any interesting events in the system or application log. The "iTunes Outlook add-in" is active within Outlook. (By the way, as of iTunes 7.3.2.6, after I removed and reinstalled Apple Mobile Device support, the other addin, "Outlook iTunes sync add-in," appears to be gone. Indeed, the OutlookSyncClient.dll file that used to be in c:\program files\common files\... is now an executable, so the deployment architecture has changed a bit.)
I ended up with an empty iPhone calendar using the new test account. When I switched back to my real account, reset the sync history and replaced all calendar items, the iPhone calendar was restored to its usual incomplete state.

Safari and Chrome causing OS X 10.6.7 to crash frequently (daily) on certain websites

I'm having problems with Safari and Chrome causing my MacBook Pro to crash almost daily when visiting some websites (e.g. ABCNews.com). It is happening more frequently after recent upgrade to 10.6.7, but has happened frequently since i bought this laptop. Not sure if it's an applet thing or not. Here's my problem details and system configuration output from the problem report:

I think a similar thing is happening to me on my 2011 MBAir running the latest updates on Yosemite (10.10.1).
First noticed issues on Chrome with websites like FB, Google Docs, some Apple support pages, Gmail, and other random sites. Chrome would show me the "Aw snap" page. Then tried resolving in Chrome by uninstalling extensions and creating a new profile with no luck. Then when I tested it on Safari, similar websites were crashing, except Safari threw up an error log immediately that looks a lot like the one above. The copied and pasted message is at the end of this post.
Then when I was editing a movie on iMovie, it started freezing up with no error messages or warning whenever I tried to edit a title manually.
It seems like a hardware issue, so I rebooted the Mac holding down D (I think) in order to get the hardware checker. Did that, no issues. Also tried repairing permissions.
If I'm seeing a pattern, I'd say that it was crashing on more complex websites like FB and Google Docs. Many other sites work fine, like this page I'm writing this post in, Google searches, etc.
I'm absolutely stumped on this one. The next thing I try will be to reinstall OS X, but I won't be able to do that for a while because it takes about 12 hours on my internet connection...
Any ideas??

Intel Core Duo, very slow start up and doesnt recognize airport

Hi,
I just got upgraded to a 2GHz Intel Core Duo (10.4.7) by Apple, after they couldn't fix my iMac G5 iSight. But ever since I got it, on the initial start up every morning, it doesn't start up right away. When I press the power button, the sleep light dims on a little, stays on for about 30 seconds (with a blank screen) then the computer will eventually start up (Much much slower than normal)
Once it finished starting up, and gets to my desktop, my airport icon doesn't show up, and when I look for it, the computer tells me that there isn't one installed (There is).
I tried just restarting it, still doesn't show up. So I shut down, and power-up again. It starts up fast and normal, and then my airport card shows up.
Any idea what is causing this?
Thanks in advance!
Mike

parks2,
Have you reinstalled your RAM?
Have you run the Apple Hardware Test? Check System Profiler under Diagnostics after each startup, as well.

So my airport extreme recently had some nat/dns issue and in the airport utility displayed a warning about it and to correct it. I wasn't sure what to do so i pressed the resolve icon and now my guest network is not working.

Anytime you change networking hardware, it is always a good idea to perform a complete power recycle of your networking components.
I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

Airport disconnect when switching users

I recently changed the password for my airport in an attempt to connect my son's new PSP to my network. (I needed a longer password to mimic a PC network.) After deciding I couldn't make it work I decided to go back to my old basestation password. Nothing was changed but the password using the airport utility program. After doing so I find my airport disconnects when fast switching users. It reconnects fine if I choose it as my network but I need to manually reconnect each time I switch from one user to another. It does it with my new Macbook as well. I've tried every setting I can find using the utility. I've reset my basestation and set it up as a new network. I used to be able to stay connected for days and now it drops whenever I switch users. I've already heard I may need to upload my basestation software again but haven't done so yet (I need to find it first) Any ideas would be greatly appreciated.

Thanks for responding... I've done that more than once. I reloaded the latest AP software and now have it so that I only need to connect one time when my G4 and Macbook are powered up for the day. They stay logged on throughout several fast user switches. I can live with this although my computers used to find the network by themselves each day when first powered up. I've decided I can live with it. Thanks again.

I changed my internet box and now my airport extreme light flashes amber what I need to do to get the green light back

I changed my internet box and now my airport extreme light is flashing amber but I have internet connection, how can I get the green light back

When you change modem (the internet box I presume) you should reset the AE to factory and redo the setup completely.
However if you merely want to stop the amber flashing.. find the cause.
Open the airport utility and click on the AE..
It will give you a list of faults or problems... fix each one and the light will turn green.
The most likely fault is double NAT.
That means the AE should be in bridge mode.. but if you list the fault we can give you further help with what to do to fix it if you cannot understand the instructions.
Apple does give a procedure to remove the problem although it may not always be the best solution.
eg Ignore.. the light will turn green.
Lately Apple is saying to use double NAT and ignore the problem.. I do not thing that is a good idea at all.
To bridge however may be easier after a full factory reset than trying to do a change to the setup.
If you run Yosemite.. then I recommend the following.. please read AE for TC.. (Time Capsule is what I mainly use but the setup is identical).
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
ie Start from a factory reset. No files are lost on the hard disk doing this.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 and TCwifi for basestation and wireless respectively.
Even better if the issue is more wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round.
2. Use all passwords that also comply but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking. If the TC is main router it will not be an issue.
In your case bridge is most likely required.. and it is up to you how you deal with this one.. for now see if it is stable.. if it gives you issues come back and fix it.
4. Set IPv6 to link-local only on the computer..
This is strange one in that apple should have fixed this up ages ago.. but we are finding the auto setting even on Yosemite is still giving the wrong setup.

10.6 Snow Leopard - Airport Disconnect with DVD use

I installed Snow Leopard today only to find out that my Airport disconnects every time a DVD spins up in my drive! Has anyone else experienced this problem?

I am sorry you have this problem. I installed Snow Leopard today on my 2007 Core Duo Mac Mini connected to Airport Extreme sending its WiFi to my 2008 Core 2 Duo Macbook Pro now running under Snow Leopard (and an semi-retired Dell Windows XP Machine) and there are no problems running Airport with or without a DVD in any of the drives. I wish I could be more helpful.

Have an older iMac and am contemplating adding a new MacBook Air and a 2TB Airport Time Capsule to increase WiFi speeds. My question is (a) is this a compatable setup and (b) will the older iMac slow the WiFi speeds?
Thanks

Be careful about mixing Time Machine backups and other data on the TC's disk. That will cause conflicts, sooner or later. See #Q3 in Using Time Machine with a Time Capsule for an explanation and some possible workarounds.

Hi I just bought the airport express, plugged it in and opened my airport utilities on my macbook and it doesn't seem to recognise it anyone have an idea what I should do?

hi I just bought the airport express, plugged it in and opened my airport utilities on my macbook and it doesn't seem to recognise it anyone have an idea what I should do?

If you are trying to configure the AirPort Express using wireless, you must first log on to the wireless signal that the Express is broadcasting to establish a connection.
Look for a wireless network with a name like Apple Network xxxxxx where the "x" could be a number or letter. No password is required to log on.
Most folks find it easier to temporarily connect using an Ethernet able as stic suggests in his post....if you have one handy. Once the device is configured, you can disconnect the Ethernet cable.

I stay in hotels alot and use my Airport Express to hard wire into hotel network. But hotels seem to have a sensor that will not allow any other device like my I-phone, I-pad to connect. Just one device and that's it. Is there a setting to cure this?

I stay in hotels often and use my Airport Express to hardwire into the hotel's network. This seems to work fine and allows my Macbook Pro to work wirelessly.
The problem is I cannot then hook up my Iphone or Ipad to the network. It seems the hotels have a sensor and only allow one device on their network at a time. Is there a setting in the setup of my Airport Express that might fix this problem?

If you have the AirPort Express setup in Bridge Mode, try changing the Connection Sharing setting to "Share a public IP address"
AirPort Utility - Manual Setup
Click the Internet icon
Connection Sharing = Share a public IP address
Update
You will probably get a message about a Double NAT error. Click to "ignore"
This setting might allow mutliple devices to connect and may not. It's worth a try...I have about a 60-70% success rate at hotels with this setting.
Unfortunately, as you note....hotels have become a lot smarter about connections to their network. At some point, they probably will not even allow another router to connect at all.

I'm looking for some help connecting linksys IP Cameras to my home network to monitor my property when I'm travelling. I used to do this with linksys WAPS, but since I've discarded all my old linksys networking and standardized on airport, I can't get these things working. I know that I have to identify my camera through the DHCP table and set up port forwarding and there is the problem.
My network consists of 4 base stations set up in a roaming network - same network name and passwords. I need to do it this way so I don't have to switch network when I move from one side of the house to the other, go to the cabana, or my shop in the barn. The network works pretty well since I went to a roaming set up. Good performance, yata, yata, yata.
However, the roaming network requires the AEBS's to be set up in bridge mode, rather than sharing an ip address. When the AEBS is set to bridge mode, you don't see a DCHP table or have the ability to identify your IP Cam through the AEBS - and hence, no port forwarding.
I am able to identify and set up my Linksys IP Cam by locating the ip address on my FIOS router, even though, it's plugged into an AEBS. I set it up, see the video, remove the ethernet cable from the IP Cam, restart - and I can't get to it from an AEBS. In researching this, it appears, I should be setting up the AEBS to "share an IP Address", going to the DHCP table and identifying the camera's IP address and setting up port forwarding. However, you don't see any of the DHCP or port forwarding options in Airport Network Utility when configuring in bridge mode.
I'm hoping I'm missing something here and that the solution isn't to set it up at the FIOS router level, but I'm beginning to think that's my only hope. What concerns me there is that I should be able to see the IP cam on the network without port forwarding since I'm not coming from outside, and I can't even do this unless it's connected hard wire.
I'd appreciate any insight into this that anyone might have. I've hit the wall with what I know.
Thanks.

In a roaming network, your "main" router is the device that would require port mapping/forwarding to be configured in order to access the IP camera from the Internet. This router is also the one that would be provide the private IP address for the camera which you will want to be a static one.
So as you described your network, the IP cameras should be getting an IP address or you assigned it a static one and this is the address that you would enter in the Private IP address (or equivalent depending on the router used) field when setting up port mapping.
If you are not able to access this camera from the local network, then this should be troubleshot first.

A view, function and TO_DATE causing an error.

I have the following statement which calls a view, VW_DIST_RPT_WORK_LIST which in turn calls a function which returns either 'Null' or a date string e.g. '07 Oct 2003' as a VARCHAR2 (alias PROJECTED_DELIVERY_DATE).
Statement:
SELECT CUSTOMER_NAME, PROTOCOL_REFERENCE, SHIPPING_REFERENCE, CUSTOMER_REFERENCE, COUNTRY, PROJECTED_DELIVERY_DATE, STATUS, NOTES,
TO_DATE(PROJECTED_DELIVERY_DATE)
FROM VW_DIST_RPT_WORK_LIST
WHERE EXPECTED_DESP_DT IS NOT NULL
AND UPPER(PROJECTED_DELIVERY_DATE) NOT LIKE('NULL%')
AND EXPECTED_DESP_DT <= TO_DATE('07/10/2003', 'DD/MM/YYYY')
AND TO_DATE(PROJECTED_DELIVERY_DATE) <= TO_DATE('31/12/2003', 'DD/MM/YYYY') --< Problem here
I need to be able to specify a date filter on the PROJECTED_DELIVERY_DATE field and hence used the TO_DATE(PROJECTED_DELIVERY_DATE) <= TO_DATE('31/12/2003', 'DD/MM/YYYY') but this is generating an ORA-01858: a non-numeric character was found where a numeric character was expected.
I think the problem lies with the fact that this field can contain 'Null' which cannot be converted to a date using TO_DATE. I've tried adding a NOT LIKE ('NULL%') statement to catch any nulls which may be creeping in bu this doesn't solve the problem.
I've added TO_DATE(PROJECTED_DELIVERY_DATE) to the select above to determine if the nulls are being caught and if the TO_DATE in performing the conversion correctly which it is on both counts.
Any ideas anyone ?

The answer provided above by Monika will work for this situation. However, you should seriously think whether you should be using a string for date datatype. Ideally, you should rewrite the function that returns PROJECTED_DELIVERY_DATE and change the return type to DATE. The least you should do is to return NULL (instead of the string 'NULL') from the function. Oracle handles nulls perfectly, there is no reason you should write code to handle nulls;
One more thing. Looking at the type of error you are receiving, it seems that you are using rule based optimizer. Why do I think so? Because, in rule based optimizer, the conditions are evaluated in a specific order (viz, bottoms-up for AND clauses). To show this, look at the following simple demonstration. I did this in Oracle 8.1.6 (also in 9.2.0.4.0 on Windows).

Does the above example seem familiar to your case? Even though you had the AND UPPER(PROJECTED_DELIVERY_DATE) NOT LIKE('NULL%') in your query, a record with PROJECTED_DELIVERY_DATE = 'NULL' was evaluated first and that caused the error.
Summary
1. Use dates for dates and strings for strings
2. Use cost based optimizer

My home network has an Airport Extreme w/Time Capsule as the base and then an Airport Express and a second Airport Extreme to reach different areas of the house. Is there a way to use the second Airport Extreme for file storage on this network?

My home network has an Airport Extreme w/Time Capsule as the base and then an Airport Express and a second Airport Extreme to reach different areas of the house. Is there a way to use the second Airport Extreme for file storage on this network? Network is administered through an iMac running OS X Yosemite 10.10.2. Ideally, would like for the second Airport Extreme hard drive to appear on the list of devices in the Finder window.

Ok.. gottcha
The problem is network wise.. Yosemite is about equal to tin cans and string.. pathetic.
Here is my usual set of instructions to get anything working on Yosemite.
The best way to fix problems is a full factory reset of all the AE in the network.
Factory reset universal
Power off the AE.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the AE to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg AEgen5 and AEwifi for basestation and wireless respectively.
Even better if the issue is more wireless use AE24ghz and AE5ghz with fixed channels as this also seems to help stop the nonsense.
2. Use all passwords that also comply but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. Ensure the AE always takes the same IP address.. this is not a problem for AE which is router.. it is a problem for AE which is bridged.. you will need to set static IP in the main router by dhcp reservations or use static IP in the AE which is tricky.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric..
5. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only.
6. Now mount the disk of the second AE in finder... manually.
Use Go, Connect to Server and type in the AE ip address.
SMB://10.0.1.2
Where you will replace that address with the actual address. The network resource should be discovered and then it will request the password.. type that in and make sure you tick to save it in your keychain.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
Do as much as you want of the above... not all of it is necessary.. only if you want it reliable.. or as reliable as Yosemite in its current incarnation can manage.
The most important thing is point 6.. mount the disk using direct IP address and not names.. dns in Yosemite is fatally flawed.
