Disconnected from Ethernet

Hello, I have just received my Cisco Polycom and had it set up but it keeps reading the message "Disconnected Ethernet"
Could you please help me with this.
Thanks.

The two problems I have seen that caused this error are;
-> cabling issue; move it to a known working jack to verify cabling. Plug it directly into the switch to eliminate cabling.
-> other is a bad phone.

CRIO disconnects from Ethernet network and stops responding to pings

We are running a cRIO application that periodically disconnects from the Ethernet network even though the VI continues to run on the cRIO.
The application has two parallel loops. One loop reads data from the FPGA and writes it to a RT FIFO. The second loop opens a TCP connection to a remote host, reads data from the RT FIFO, and transmits the data to the remote host. We have instrumented each loop to send messages to the serial port that indicate their status. When the cRIO disconnects, both loops continue to send their status messages to the serial port. The first loop happily continues reading data from the FPGA and writing it into the RT FIFO. The RT FIFO overwrites the oldest data when it fills up to keep it from overflowing. The second loop reports a TCP write timeout (tcp write error 56) around the time that the cRIO disconnects, after which it closes the existing TCP connection and then repeatedly tries to open a new TCP connection (each attempt times out after a 5 second delay).
All that appears normal and usually the connection is automatically restored. Occasionally, however, the cRIO is not able to re-open the TCP connection. Furthermore, the cRIO stops responding to pings from the remote host. On two occasions, the cRIO was finally able to open a new connection after 30-40 minutes. Other than that, the only way we've found out of this dilemma is to reboot the cRIO.
The frequency of the disconnects and the time before they occur doesn't seem connected to whether or not the cRIO is set to run the application at startup or if the application is run via an interactive VI window on the remote computer.
It is possible that the disconnects have something to do with which computer the cRIO is connected to, as the problems seem to happen much more frequently (often within minutes) when the cRIO is sending data to a laptop running Windows XP, but it can run for hours when sending data to a rackmount server running Windows Server 2003. Everything else (the speed and size of data being sent, the ethernet hub and cables, the VI running on the remote computer) is the same.

We're done most of the testing with a 9014 real time controller and a 9104 chassis. However, we've also seen similar behavior with 9014/9103 and 9102/9101 combinations.
The 9014 cRIO normally runs at around 50% CPU usage and less than 40% memory usage when the data is flowing steadily. The RT System Monitor did not indicate a spike in either before the cRIO disconnected.
Measurement and Automation Explorer is not able to connect to the cRIO after it disconnects. We tried pinging the cRIO from a different computer, but that also failed.
After disconnecting, the cRIO sends error messages to the serial port while trying to open a new TCP connection. It reports an error 56 (time-out error) 3 or 4 times (for a total duration of 15 or 20 seconds) and then reports an error 42 (generic error) at least 10 times per second for 18 seconds, and then switches back to 15 seconds of timeouts, and so on. When getting error 42, it ALWAYS gets it for 18 seconds straight. It usually gets error 56 for 15 seconds (3 timeouts) but sometimes for 20 seconds (4 timeouts).
When the cRIO disconnects, it can't be contacted by any computer through the ethernet port, yet the link lights still show that it is connected. If its connected directly, both the green and orange link lights on the cRIO light up, but when it is connected through the 10 Mb hub, only the orange link light lights up, but the hub shows that the cRIO is connected to it. In spite of this, it is still impossible to ping the cRIO in either scenario.
It is possible that, in addition to what computer the cRIO is connected to, the errors could be related to whether the cRIO has a direct connection to a computer or if it is connected through a hub. Today, we have only managed to get errors when the cRIO is directly connected to a laptop (one error after 1.5 minutes, one after 10 minutes, one after 7 minutes, etc.) There were no disconnects when the cRIO was connected to a 10 Mbps hub for more than half an hour.
Do any of those symptoms give you clues about what is happening?
Thanks!

Activate Airport on Disconnecting from Ethernet

Hey, I have a computer I use as a server, so I have it by default plugged into the Ethernet, with Airport Off (so that it uses the ethernet network). But I need to remote into it from off the network, and if it gets accidently unplugged, airport will be off. Is there a way to activate the airport in the event of the deactivation of Ethernet?
Sorry if this is the wrong section

You would have to be in front of the computer to re-activate AirPort. Seeing as how you are using a Mac mini, it should stay stationary for the most part, so there will probably be no need to work about the ethernet coming unplugged. If you have it plugged into ethernet via your router, I believe you can still access the computer remotely. I sometimes connect my MacBook Pro to my ethernet connection and I can still reach it form my iPad. If I may I ask, why are you using ethernet with a Mac mini?

How to change gateway in windows 7 from ethernet to usb 4g modem?

We have a Windows 7 machine that is connected to internet by satelite through ethernet. This workstation also has a USB 4G modem that should be used by a software application. We would like to have all network functionality to go through normal ethernet
traffic and just 1 software application to use the USB 4G modem. How can we set this so we don't have to disconnect everytime from ethernet when we would like to use the 4G connection by the USB Dongle/Modem??

Hi GadgetServer,
If my understanding is right, you want to use USB 4G modem for one software and other network traffic goes by normal Ethernet.
I think we could add route table if you know the detonation address that the application will visit.
For more information about adding route table, please refer to the following article.
http://technet.microsoft.com/en-us/library/bb490991.aspx
Additionally, we could contact the software publisher to see if there are options to choose the USB 4G modem.

my apple tv is disconnected from the wifi intermittently, the problem is not the wifi as it only happens to the apple tv. that I can do to fix this problem.-

That doesn't rule out a network issue, as it can impact devices differently. Intermittent issues are most often related to wifi issues. Try connecting via ethernet. Go to istumbler, netstumbler or similar to get a report of the network, look for signal strength and noise.

MBP Airport consistently disconnecting from the Web, but not the network

My MacBook Pro Airport has been cutting in and out - or at least the Web access has - when I use it in combination with a DLink router. The local wireless network connection always seems to stay connected (or at least it says it's connected), but I can't access the Web. It has shown these symptoms when used in combination with other routers too, but only when I use it with the DLink first and then move to another network.
I can sometimes fix the problem by a combination of restarting OS X and resetting the PRAM, and restarting the router. However, this doesn't always fix the problem, and even if it did, I'd probably be doing it at least once a day with the current frequency of disconnections. So I'd like to get to the route of the problem.
An ethernet connection to the DLink router always works without a hitch.
Does anyone have any suggestions or any knowledge that might help resolve this?

Just remembered I have the 'self assigned IP' error too. There seems to be a fair few posts about this issue. I haven't found a definitive fix yet, but these posts might hold some clues;
http://discussions.apple.com/thread.jspa?messageID=6710925&#6710925
http://discussions.apple.com/thread.jspa?messageID=6708778&#6708778
The second post suggests applying the 'Disconnect from wireless network when logging out', which I've applied, because I've noticed that I often see the problem when I put my MBP to sleep.
p.s. Last year I quick-fixed this issue by attaching a Buffalo wireless router to the network as an extension and connecting to that instead of the Dlink. But I just gave the Buffalo to someone, having forgotten about the issues with connecting to the DLink.

Cannot bring up saved page, complete or HTML only, if disconnected from internet: "Server not found"

I right clicked, chose "Save Page As...", chose both HTML Only and Complete on 2 different tries. When I tried to bring the page back up when disconnected from the internet network, I receive the "Server Not Found" error page. I shouldn't have to be connected to bring a saved page back up. I've not had this happen before, and it has only happened w/ a particular page, but one which is perfectly normal. What might be the explanation and solution? Thank you.
Jeff Bowrs

I would start with seeing if the Web Browser on the G4 can get to 192.168.0.1 which should be the web server (Set Up pages) on the router.
If that does not work I would double check the cable (Use another).
If you can I would connect two computers together and see if the Self Assigned IP (169.xxx.xxx.xxx) works to eliminate the Ethernet Card.
You have no connection to the Internet.
You need to sort out where it is breaking down.
As other devices seem to get on the 'Net then it would appear to be:-
The Ethernet Port on the routing device.
The Cable itself.
The Card or Port on the Mac

I have two problems with my 2012 13" MacBook Pro. 1. Gray screen shows at startup 2. Randomly disconnects from network. Any help will be greatly appreciated.

I have two problems with my 2012 13” MacBook Pro.
Gray screen shows at startup
Randomly disconnects from network.
Any help will be greatly appreciated.

First, open Terminal in your Utilities folder and paste this into the prompt line:
sudo update_dyld_shared_cache
Press RETURN. You will be prompted to enter your admin password which will not be echoed to the screen. Press RETURN again.
Next, boot the computer into Safe Mode.
Next, do the following:
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Disconnects from internet when it goes to sleep

I have Mountain Lion on an iMac I purchased in 2010. Once I installed Mountain Lion, it started disconnecting from the internet when it goes to sleep. Does anybody know how to repair?

Oh yeah I forgot to say I use an ETHERNET connection.

Apple TV Randomly Disconnects From iTunes While Streaming Videos

Hey All,
Anyone having an issue where your Apple TV randomly disconnects from your iTunes on another computer while streaming videos from it? Randomly, on different shows and movies, I have had it do it quite a few times.
In the beginning, after it would disconnect, within a few seconds, it would reconnect to iTunes and then I would have to navigate back to what I was watching and and resume it. Now, it will disconnect, and then I will have to quit iTunes on my iMac and then start it up again.
I am curious if it is an issue with the wireless adapter on the ATV because when it happens, it looks like it losses complete connection with the iTunes and then reconnects to the net only after. Then I would need to restart iTunes on my iMac to continue watching my show.
This was happening before the recent update and continues after the update as well.
Any suggestions are appreciated. Thanks!

You're talking about those WIFI bridges they make for xbox 360s that connect the 360 ethernet to a wifi adapter, bridging it?
That is a possible solution, but I will definitely check with Apple first, hoping it will be a no money solution (I am a grad student, every dollar helps).
My apartment is two rooms, my iMac being in another room, so that wouldn't work. The Wifi extender will probably be my only hope if Apple is not cool with the helping a brother out.

Apple TV's disconnects from itunes

I have 2 apple TV's streaming from my mac mini. Whenever I reboot my iMac into bootcamp both AppleTV's disconnect from the iTunes on the mini. This is very weird because I have nothing pretty much on the bootcamp part that would interfere with it, not even iTunes installed. Anyone have a clue as to what might be causing this? Both ATV's are on wireless N to my Airport Extreme router.

E4200 built in Twonky media server disconnecting from PS3

I am having problems with Twonky disconnecting from my PS3 while watching movies from the attached USB drive...anyone else having this issue?
Any ideas on how to manually restart the media server other than turning off the drive or resetting the router? Or perhaps a solution to this in settings...

Same problem here with an XBOX 360. Seems to be a common theme in several threads. The only solutions I've seen posed by admins is to change the MTU to 1365 which doesn't make sense since these problems are reported for hardwired devices and ethernet already does 1500, or to upgrade the firmware and/or reboot... none of which work. I also get the same issue when streaming to a laptop from the router, but have zero issues when the same drive is plugged directly into the laptop. I've also had issues where the Storage tab only reports as connected to the drive at USB 1.1 until a reboot of the router. It will also say "No disks available" even though I can connect to the drive through UPnP. My drive is a Seagate 2TB on the "supported" list of external drives. I would just like someone to acknowledge this is a real problem with a solution forthcoming or I'm going to have to assume it's a hardware fail that no future fix/firmware update will solve or this thing is going to have to be returned.

Airport Express disconnects from LAN overnight

I have set up a brand-new Airport Express (v. 7.6.4) recently. The AP Express is connected via the Ethernet 1 port to a Power Mac running OSX 10.9.5 (Mavericks). The AP Express is in "Join a wireless network" mode, and it connects to a LAN consisting of a cable modem/router, a "smart TV," a printer, and a MacBook.
Most of the time, all of this works fine, and the Power Mac gets a nice fast wireless Internet connection, which is the main objective of having an AP Express. (I'd rather use a direct Ethernet connection between the Mac and cable modem, but that would require snaking a long ugly cable thru my living room somehow.)
However, once or more per day, the AP Express gets disconnected from the host Mac (and the network) The symptom (sometimes) is that AirPort Utility reports that "no configured Airport base station has been found." Another symptom (sometimes) is that the AP Express is visible, but is reported to have a "self-assigned" IP address. It's SUPPOSED to be getting its IP address via DNS, and if it can't do so, no Internet connection...
This **seems** to happen when there is no traffic between the host Mac and the AP Express - most typically, overnight. I don't know of any "sleep" mode on the AirPort... ?
Sometimes, I can get the connection back up by tweaking a harmless parameter in AP Utility and forcing it to "update" itself. In the worst case, I have to power down the AP Express and reconfigure the whole thing.
AFAICS, when this happens on the AP Express, the other devices are talking nicely to the cable modem.
At this point I'm at a total loss.... I thought that this would be a very simple installation, it's very disappointing to have to in effect "reinstall" the AP Express every morning...
thx -- John

I phoned Apple Care and brought the AirPort to the Apple Store
