Apple TV looses network configuration

Hi people;
I have configured my Apple TV and everything works fine. I accessed ITunes, photos etc...
When I put the AppleTV on a stand by mode it loose the network configuration every time.
Does somebody know how to save the network configuration in oder not to loose it?
Thanks;
Joaquim Santos Neto

It might not solve your problem but you could eliminate it as a possible cause by changing to a 5 letter password for 64/40 bit encryption or a 13 letter password for 128/104 bit encryption.

OEL 5.6 after reboot looses network configuration

I have a HP-DL980 with OEL 5.6 kernel 2.6.32-100.26.2.el5 #1 SMP Tue Jan 18 20:11:49 EST 2011 x86_64 x86_64 x86_64 GNU/Linux
It has 2x 10Gb NIC's and 4x 1Gb NICs, after a reboot the server looses network configuration and can't login or ping the server. NIC's were replaced and tested in another server and they work fiine, cabling re-checked works fine. I am able to reproduce it on a DL-585 as well with the same OEL version and kernel. I've tried to re-enable the NIC's and still no connectivity.
Any thoughts, ideas?

I think you may be correct. The DL980 has a extension board where the NIC card is added. I don't have this issue on a DL585. If I remove the module from the kernel and reload it then it appears to work, only if the server reboots it doesn't recognize the cards at all and gives me the error messages above. I have opened a call with oracle, working on getting the files to them right now. thanks for the note on the bugzilla. I'll check it out. I posted info on the bug 680411 and got a response back that they do not have such a kernel and it is nont related. I am using the OEL5.6 with the unbreakable kernel.

Multihomed network configuration

So, when I say multihomed what I really mean is that Macbook Air is configured to use two network interfaces -- Wi-Fi and USB ethernet -- in one Location. Each interface is configured to work on a different subnet. In fact, wi-fi is assigned a public IP address of 195.88.xxx.xxx, and USB ethernet NIC a private address of 192.168.0.252/24. Wi-Fi is en0, and USB ethernet is en2. Both interfaces are in active state.
My goal is to have MBA to route all traffic to en0, except for 192.168.0.0/24 network which I want to go via en2, the USB ethernet card.
The topology is pretty simple:
Linux Laptop <--- Linksys Cisco Router <---   en2 via <--- MBA ---> via en0   ---> Linksys Cisco Router ---> <Internet>
Essentially, I need to put en2 on the ethernet segment where the Linux laptop is to be able to talk to it directly. No routing needed. This apporach works without any problems in Linux environment. However, on Mac OS X it doesn't work and it makes me wonder why.
A few details on what happens on the network:
tcpdump output from Linux machine (it is assigned 192.168.0.253/24):

I tried Service Reorder (in System Settings->Network) and set en2 as the first device on the list, or one position behind en0. It doesn't change anything.
My question is similar to these discussions:
https://discussions.apple.com/thread/2297388?start=0&tstart=0
https://discussions.apple.com/message/9984744?messageID=9984744#9984744?messageI D=9984744
and in one of them it is implied that no extra configuration should be made beyond what I've already done, but clearly Mac OS X doesn't see ARP request reply from the Linux machine.
BTW, firewalls are down on both systems.
I also found this network configuration manual for Princeton University campus network
http://www.net.princeton.edu/mac/network-config-x-10.8/caveats.html#ip-weakend
that claims that Mac OS X actually cannot do what I'm attempting to and refers to Weak End System Model which in essence is described in RFC4907 as:
In the Weak End System model, addresses refer to a host. As a
        result, packets sent on an outgoing interface need not
        necessarily have a source address configured on that interface,
        and incoming packets whose destination address does not
        correspond to the physical interface through which it is
        received are accepted.
That could explain why ARP request reply never makes it back to Mac OS X.
So, any ideas? Any tips?
I'd highly appreciate help of the community because I'm stuck

I dont have a PSC2210 but one of the documents I saw said to go to the front panel of the printer, press the Setup button, press 6 and then press 1 to print the Network Configuration page.

Mac Mini Late 2012 OS X 10.9.4 loosing network connectivity

I haven't found the exact issue on the forums nor outside it so I'm creating a new thread.
My Late 2012 Mini started loosing network connectivity after upgrading to 10.9.4, both WiFi and Ethernet.
Sometimes it takes around 5 minutes, sometimes more than 30 but the connectivity gets disrupted continuously, the packets stop going in or out for around 30 seconds. I've done PRAM and SMC resets, I've changed network locations, nothing helps and I've found nothing interesting in the system logs.
Also I can't login to the Apple bugtracker due to some error so I'm reporting it here.
The only USB devices i have connected are keyboard and mouse.
Any help will be appreciated.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Getting Apple's "Midi Network" to work

I recently purchased a new MacBook Pro computer to work as a wonderful "slave computer". Basically, because I extensively use the "CPU & Memory hog" Kontakt/Kontakt Player programs, I purchased the new MacBook Pro to divide the work load. So far, it's proven to do this nicely! The MacBook Pro is a 2.4 Ghz Intel Core 2 Duo with 4 GB's of SDRAM running on Leopard 10.5.4. I have an external hard disk drive which houses all of the instrumental sound libraries. The external hard disk drive is connected to the MacBook Pro using an eSATA connector. The audio device used is a new MOTU 828 MK3.
My older Mac Pro workstation is noted below. Please note that I have not upgraded the older Mac Pro workstation to Leopard YET. Although I do plan on upgrading the operating system, things are working quite fine using 10.4.11. I use M-Audio's Keystation Pro 88, connected to the older Mac Pro workstation, as the midi controller.
The issue. . .
I can't get the Apple Midi Network to work between the two Apple computers. They both seem to see each other, but midi information does not seem to be transferred between the two computers.
At present, I have both networked via a NETGEAR 8 Port 10/100/1000 Mbps Gigabit Switch. This is so that I can have access to the Internet. Now, I am able to transfer files between the two computers. Both computers seem to "see" each other using this network method.
For the MacBook Pro, I am using a CAT6 ethernet cable. I think that this is also true for the older Mac Pro workstation.
I believe that I am configuring the "Midi Network" function correctly. I can see it via the Logic Pro 8.02 program (in the Environment).
Finally. . . I am able to use Music Lab's MidiOverLan CP3 between the two Apple computers!! This is solid! Why, though, am I NOT able to get Apple's "Midi Network" to work?? Am I misunderstanding its function?? Does it not work when one computer is operating under Leopard and the other (older) computer is using the older version?? Could it be the CAT 6 cables?? The NETGEAR switch??
At present, I am happy using the MidiOverLan CP3 program to communicate midi information between the two computers. It would be nice to be able to correctly use Apple's own software, though. (Maybe it's user error??)
Thank you in advance.

Several months ago, I DID get this feature to work...And I'm sorry, I don't remember exactly what I did. It took several attempts. I linked my intel and PPC mactogether.
The problem was, there was too much of delay to make this a useful feature for realtime recording. I was trying to play a virtual instrument, that was a PPC plug-in while recording on a newer macpro..
If you were willing to create 'scratch' tracks one computer, using native Logic plugins, until you had all the midi data right. and then wanted to port midi over to the 2nd computer, and create a more detailed sound to port back into your 2nd computer, it CAN be done. but like I said the delay was too much..(I couldn't get it to be a realtime feature)
There was a 'delay adjustment' feature, in the midi, but I couldn't get that to be useful. If you have plug-ins that you absolutely can't live without, you can try this, but I found it to be too much trouble, and there were some computer lockups involved.

IOS 5 not saving Network configuration - bug

Can't find a place to report this bug so I'm doing it here...
1. Upgraded both iphone 3GS and Ipad 2 to IOS 5 - all working correctly.
2. Changed Enteprise password (due to corporate policy).
3. Now both devices require manual configuration of WPA2 Enterprise authentication whenever they are woken up. The network configuration is clearly being reset to WEP when they go to sleep.
I therefore conclude that the Authentication type is not being stored correctly by IOS 5, hence it is reverting to WEP.
Apple - please fix asap as this is severely impacting corporate use of both devices.
Thanks.

We also have deployed ain our company a number of iOS devices (iPhones, iPads, etc.). We are using WPA2 Enterprise as a security protocol and all our devices had no problem at all connecting to the WiFi network when at iOS 4. When we started upgrading devices to iOS 5, we started having exactly the problems you mention in your posts. I agree that this should be a major bug to iOS networking facilities, because it seems that it cannot store the WiFi account preferences with the correct authentication type and credentials, resulting in our devices not being able to enter the network AT ALL after being upgraded to iOS 5.
The nice thing regarding the issue is WHEN this issue occurs and when it is not. (it doesn't occur in all devices upgraded so far). If you have upgraded your device to iOS 5 from scratch (restore from iTunesand "Set as New Device" settings (no Restore from backup), then the issue emerges automatically for us.
If your user just upgrades when the iTunes message pop up appears, or manually ("Check for Updates") then all devices behave normally after the upgrade.
Something should be done ASAP, because we are facing a major problem over here...

Reset WLAN network configuration - What .plist file?

I would like to reset my wireless network configurations, delete all network related preferences and settings and start over. This helped me before to solve a problem that I was unable to connect to a network at work.
The 802.11x settings won't load the certificate from the domain that will enable me to connect to my corporate WLAN network.
Can somebody tell me which files these were, so that I can delete them and start again.
Any ideas why this keeps happening and what files these are?
Thanks for any replies and all help.

In Keychain Access, search for the certificate. I don't know how you can check if it is loading. You might just try deleting it and reinstalling.
There are functions in the Keychain Access>Certificate Assistant>Evaluate

Apple TV looses connection to iTunes library after Update 5.1.1

Since I updated my Apple TV to 5.1.1 and iTunes to Version 11, my Apple TV looses repeatable connection to iTunes music library (via wifi)
after ca. 20 min. Any ideas what to do?
Thx, PM

Network Configuration keeps resetting prefs (Three ZTE MF627 Dongle inside)

So I had the problem discussed in this topic (http://discussions.apple.com/message.jspa?messageID=10239922); I followed Lee Collier's instructions in the 6th reply, and it worked like a charm.
The problem is, when I unplug the dongle or when the connection falls for any reason, Network Configuration resets my preferences and I have to set it up all over again. Any idea why that happens?

Anybody out there with the same problem?
This thing is really annoying.

Loose network connection after sleep

Everytime my macbook pro sleeps it looses network connections in my home and I have to go through re-establishing connection including network password

This seems to be a common issue on most Mac platforms lately. I have 2 Macbook Pro's and 1 Air all experiencing this issue. It only happens on hidden networks, at least in my case and most I have read. I have yet to hear any official response from Apple but there must be at least 15 threads on this exact topic thoughout the forums.
Some people claim removing all the "Remembered" networks and re-add them fixes it. I have noticed the only thing that seems to work is if I remove all networks and if I have a hidden network, it can be the only one listed. As soon as I add another saved network hidden or not, the problem comes back.
This is hard since most of the end users that use the macbooks on our hidden networks also use them at home. So they naturally have multiple networks listed. The odd thing is its not ALL of them. We have a bunch of other Mac's that do not experience this issue.
I know this is not a solution but it is what I have found so far...

Wireless printing with 2 (or more) printers + manual network configuring

Here's my previous question:
Network configuration: Cable modem (Linksys)-Wired cable router (Linksys)-Airport Extreme Base Station. Wired cable router is used for VOIP phone which is left on 24/7. Base station is shut off when not in use. I had 2 printers, HP multifunction and Samsung color laser printer connected to the Airport via a USB hub, but I could only print from 1. The printer I wanted to use had to be ON and then the Airport turned on to recognize it. So, I purchased a dLink DPR-1260 wireless printer hub. It had to be configured with a Windows operating system, which I did with an XP business laptop. The printer hub had to be configured wired and then the Cat 5 cable removed. The IP address: 10.0.1.2 (dynamic) is what Airport gives whenever anything is plugged into that port. MAC address: 001E589D8035 (which is what the printer hub says on it). SSID is correct. Raw TCP port and LPR/LPD enabled. Re-established Firewall and WPA2 security. Both printers work fine (even scan on HP) wirelessly with Windows XP laptop.
However, neither printer works with either MAC (G5 or iBook) Although they both (HP & Samsung) appear to be ready and start the printing process by downloading percentages of the job.
New info: The IP address of the dLink (DPR-1260) print server is now 10.0.1.3 (Airport is 10.0.1.2) I can connect to 10.0.1.3 thru Safari (or Firefox) and see the device info. I can't configure there. dLink told me to manually configure in network preferences. Their instructions told me to manual change the print server address to 102.168.0.x (x not 10). Then make Appletalk active. When I tried to add the DPR-1260 on the network is said IP Config 10.0.1.3 in use by 00:1e:58:9d:80:35 I guess I need to start over. How can I add the DPR-1260 manually to the network?

xee -
You have two simultaneous problems. Print Server setup, and network-capable CUPS driver required for each printer. Unless either printer is a postscript one, the drivers provided by the manufacturers are Carbon-type, limited to exactly what they programmed it for - probably USB only. That's why Airport Extreme/Express have an advantage over other print servers - Apple has put Mac-to-Mac printer sharing into Extreme/Express, so a USB-only driver works over the network. Other print servers require use of the industry-standard comm protocols LPD or raw port 9100 (=HP Jetdirect) or IPP. Those standard protocols are provided by CUPS and you have to use a CUPS driver with them.
Make it work:
1. Allow the print server to get its IP address just as it has.
2. Install CUPS drivers:

How to handle changing IPv6 network configurations

Hi,
I run a Mac Mini as a server with OS X Server 10.8.5/2.2 on it using an internet connection with DS-lite. The server runs fine on a private IPv4 and a public IPv6 assigned by the ISP thrugh my router. Now from time to time (on some really odd days 5 times a day) my ISP decides to change my IPv6 prefix and as a consequence the IPv6 of my server. This results in a warning and some services seem to work not always properly. When I handle the warning and update the network configuration (although all relevant pieces of configuration that are shown along this proces remain unchanged), everything is back to normal.
Now I wonder whether there is better way to handle changing IPv6 prefixes while everything else is unchanged? Any thougths? Thanks. Steffen

I'll add my 2 cents too Sudheer...
I suppose your versioning strategy should take into account your particular circumstances, impact analysis, ESB architecture etc...
In our case it makes sense to version the service operations because we have some consumers that want to stay on the older version & other that want to move with the changing versions...
We've noticed that SAP, with the standard delivered enterprise services also version step the service operations so you esentially have 2 service contracts but one that caters for additional fields/functionality. The consumer uses the service operation that they prefer.
The other possibility, if you are in a position to make the new fields 'optional' then you could do that without impacting all the consumers, the consumers that have the additional info to pass in the request can do so & the other consumers can carry on business as usual.
Then you could also version step the entire service, that would entail making use of a new software component version but this would entail new endpoints & depending on your architecture it could impact all your consumers. If you're using an integrated ESB architecture, your consumers would have one endpoint & the ESB would route the request to the relevant service version.
So you could minise impact on the consumers & develop a good versioning strategy depending on what your current situation is.
Regards, Trevor

Can you connect an Apple TV to a non-Apple Wi-Fi network?

I just purchased an AirPort express with the hopes of using it for AirTunes while being controlled by my iPhone 3G as the remote. After a number of setup issues Apple support told me that I need an Apple wireless router if I want to use AirTunes and surf the internet at the same time. AirPort express can't join an existing non-Apple Wi-Fi network, it needs to create it's own one. (This means I have to disconnect from my internet connection in order to listen to AirTunes.) Does Apple TV have this same limitation, or can you just connect Apple TV to an existing non-Apple Wi-Fi network? (I'm pretty sure that Apple TV has AirTunes too.)
My AT&T U-verse already provides me with a wireless base station; I don't want to have to purchase another one and have redundant routers.

yes of course.
you can connect it to any wifi network (assuming you know the wifi key of course).
the host itunes library will need to be accessible on that network though.
