Keep losing connection to ePrint Server

I have a Photosmart C410a printer which is connected via ethernet (wired) to my router.
I check the ePrintcenter site now and then and over the past few days, I've frequently found that the printer is listed as "Not Connected" even though my router shows that the printer has an outbound connection. I have to turn the printer off and on to get ePrintcenter to show everything as green.
The latest time I had even powered off my printer and turned it on only a few hours earlier so I would have assumed it would be connected, but it wasn't. I had to power it off again and turn it back on.
I don't know why it's doing this. Any ideas?

i have the same problem - when someone else remote-prints on the network, my Mac loses connection. How do I get it back?

IMac keeps losing ISP, internet and Server but still connected to wifi

My Imac keeps losing ISP, Internet, and Server but is still connected to the Wifi. To recnnect, I have to go into Netwrok Diagnostics - assist me. This is happening every twenty minutes or so (sometimes less). Can anyone help? I might add that we have recently moved house and never had this problem before.

Wifi problems seem to crop up a lot on here and unfortunately there doesn't seem to be a 'one fix' solution.
However, sometimes any one of the following can help although, unfortunately, not always. In no particular order:
Check wifi security - if it's WEP change it to WPA or WPA2 (preferably, as it's more secure)
Change the wifi channel on the router
Create a new Network Location: http://support.apple.com/kb/HT5289
Reboot the router
Also take a look at this link and the links within the article for other ideas. They mainly reference Lion, but still seem to be relevant to Mountain Lion:

External drive conntected to Time Capsule keeps losing connection

I've been having this problem since I bought my TC over one year ago. Other than this everything works fine (aside from the occasional need for a restart).
I have an external 500GB drive attached to my 500GB TC via usb. I use the TC strictly for backups and the other drive to host my media files. When I want to use those files I switch on the drive. Only about half of the time does that work. When it does work everything is fine. I see the drive in the finder as expected.
When it doesn't work, I can see the drive name in the finder. But if I click to go into the folder, I get an error saying that the connection cannot be found.
It shows up in the Airport Utility as normal.
Powering the drive off and on does not help.
Relaunching the finder doesn't help either.
The only way I can connect to the drive again is to either logoff and log back into my mac, or restart the TC.
It seems that my computer is remembering some kind of network disk mounting settings that don't get refreshed when I turn on the drive, but then do get refreshed when I logoff and back in. Does anyone know how I could force that refresh to happen? Has anyone had this problem before?
Any suggestions would be much appreciated
PS all my software and firmware are the latest.
Thanks.

Since updating to iso6.0 I have had problems with my email exchange account syncing correctly - I keeps loosing connection with the server.

Are you losing the connection to iTunes on the iPad or the computer? You are saying that iTunes is updated. Of course iTunes is updated when you update the iOS software. That's a no brainer.
If you mean that iTunes is updated on the computer, that has absolutely nothing whatsoever to do with downloading and updating apps on the iPad itself so changing the date on the iPad, signing in and out of the stores on the iPad .... Doing any of that on the iPad would have nothing to do with iTunes on your computer.
If .... you have not been able to connect to the iTunes or app stores at all on the iPad - try this ...
Settings>Privacy>Location Services>System Services (swipe to the bottom of the page to find this)>Location Based iAds>Off.
If the downloads are stalled or "waiting" - try these suggestions.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
Make sure that you do not have a stalled download in iTunes - a song or podcast .... if you have a download in there that did not finish, complete that one first. Only one thing can download at a time on the iPad so that could be what is causing the problem.
If you can't connect at all - you can also try rebooting your router. Unplug it from power for about 30 seconds and then plug it in again.

HP 8500 Printer and Connection to eprint server

Refurbished Printer: HP Officejet Pro 8500 Premium A910 n (Changes status from new to refurbished 02-17-2011)
ISP: ATT DSL
Modem/Router: 2wire new from Best Buy. It is white with ATT logo on it. Is using latest firmware.
Network: ethernet
The printer downloaded and installed a firmware update after initialization. So it is connected to the internet.
It then tried to register to the eprint server and said it cannot connect to eprint server.
The printer functions normally in every way except it will not register to eprint server.
Numerous calls and hours with HP Support rebooting, resetting and everything else under the sun have done nothing.
I tried setting IP and DSN addresses per all the suggestions in these forums and nothing works.
Could there be an issue with the HP Sever? Does it really exist? Are there compatibility issues with 2wire router.
ATT did remote session on my computer and could find nothing they could do. They were able to plot a test page remotely.
Any suggestions or help would be greatly appreciated. Thanks.
NEW INFORMATION (02-11-2011):
I noticed today while looking at the EWS that the printer SSID is not the same as the router, but it was grayed out. Does this matter for ethernet? If so how do I change it? I do not think this matters for ethernet.
NEW INFORMATION (02-12-2011):
The support team at 2wire have given me procedure to completely open all in and out traffice to the printer. They said if this does not work then the problem is with the eprint server. I will try this on Monday, but I expect there is a communication problem between the printer and the eprint server that has nothing to with anything at my location or my ISP. Is there any way to check the server this printer is trying to connect to? Where is it? Is it operational? If not, is it rerouting properly to an operational server? The printer must be trying to access a particlar IP address or DNS to establish communication.
NEW INFORMATION (02-14-2011):
Per the instructions from 2wire support team I opened all ports and allowed all services then turned the printer off and on. It did not work. The printer will not connect to the HP eprint server. So the problem is with the HP eprint server. This printer is programmed to look somewhere for a server to connect to. Where is it? Is it operational? Why will not allow a connection? HP the ball is in your court. What can we do?
I have ATT DSL at work and Charter Cable service at home. The problem is the same for both locations and ISP's. Is there anyone out there has connected that has ATT DSL or Charter Cable? If so what are your settings?
NEW COMMENT (02-15-2011)
Can anyone at HP tell me why the printer will connect to the HP Server and download the firmware update, but will not connect to the HP Server to register to eprint? It all seems to be on HP's side. When will we get a fix?
NEW COMMENT (02-16-2011)
The model number is blank in the engineering menu and the printer diagnositc page. If this is an issue can it be added with a firmware update? Do I need to get money back for this one and buy a fully configure one in a local store? Maybe the blank model number is throwing all the other information out of place that is being sent to the server. Can the server be updated to accept blank model numbers?
POSSIBLE SOURCE OF PROBLEM - SOLUTION PENDING (02-16-2011)
I JUST LOOKED ON THE BACK OF MY PRINTER. IT HAS A REMANUFACTURED STICKER ON IT.
It appears that the missing model number on the remanufacturered units is the reason why it will not connect to the eprint server. Print out the printer diagnostic page and see if the model number is blank.
HP is working on a fix.
SOLUTION- (02-22-2011)
I UPGRADED MY ORDER FROM REFURBISHED TO NEW REPLACEMENT. THE NEW REPLACEMENT CONNECTED THE FIRST TIME TO EMPRINT SERVER - NO PROBLEMS. I HAD TO PAY FOR A NEW ONE AND THEY WILL CREDIT MY CARD WHEN THEY GET THE REFURBISHED ONE BACK.
LESSON LEARNED - IF YOU HAVE PRINTER WITH BLANK MODEL NUMBER YOU WILL NOT ABLE TO CONNECT TO EPRINT NO MATTER WHAT YOU DO!
Thanks if anyone can help.
This question was solved.

Try setting a fixed IP/DNS…hopefully you haven’t tried that yet. (The problem is most likely w/how therouter and the printer are communicating…setting the fixed IP/Manua DNS should fix it. )          If previous steps didn’t help, you may need to set a fixed IP address/DNS Server on your printer.
Setting a fixed IP address/DNS Server for your printer may resolve web services connectivity issues that can occur on some networks with some routers. Note: This may be particularly helpful with networks using DSL/VIOS routers.
Please read the entire set of instructions through completely before trying them. You should not attempt these on your own if you don't understand networking basics. Most of us have a "techie" buddy/friend/family member...if you're not comfortable this might be a good time to call him/her, or contact HP support.
Before you begin, we recommend you first remove Web Services from your printer. (See the previous section for where to find this on your printer.) Removing web services will remove your printer from your HPePrintCenter.com account (if you have previously set up an account and added it). When you re-enable web services after completing these steps you will have a new ePrint email address and need to add your printer to your ePC account again.
Setting a manual IP address/DNS Server on your web-connected printer:
Print a Network Configuration Page from the printer front panel. On some printers this will be under Wireless>Wireless Settings, and on other models use the “Print Report” option from the Wireless status screen accessed from the wireless icon on the printer home screen.   Note the printer's IP address that is listed in the IPv4 section of the report. On most printers you can also see the printer’s IP address from the Wireless menu, or on the Wireless status screen.
Type that IP address into your browser address bar (where you would normally type a web page URL) and hit enter - this will load the printer's internal settings page (also known as an Embedded Web Server, or EWS)
Select the “Network” or “Networking” tab (the label varies depending on printer model) from the tabs along the top of the screen in the EWS
Depending on your printer model, the next step(s) will vary:
Select the “IPv4” option from along the left side of the Networking screen
or
Select the “Networking” option from the left side of the screen
Then select the “Network Address (IP)” option from the left side of the screen
The screen you end up on should be the “IP Address Configuration” screen. That screen allows you to choose an Automatic or Manual (i.e., fixed) IP address for your printer, as well as Subnet Mask and Default Gateway values. You will use this screen to set a Manual IP address for your printer.
To continue:
Select the radio button next to “Manual IP”
Select the “Suggest a Manual IP Address” option below the IP address fields. The Manual IP address fields will automatically populate with suggested values.
Select the “Manual DNS Server” radio button in the DNS Address Configuration section
Enter the address just entered in the “Manual Default Gateway” into the “Manual Preferred DNS Server” field. Leave the “Manual Alternate DNS Server” entry blank.
Carefully double-check the values you entered to make sure they are all correct.
Click 'Apply'
Save any open documents and close any web browsers on any computers
Turn off the printer and unplug the router.
Plug in the router, wait for it to start up and for status lights to settle down (approximately a minute at least), then turn on the printer.
If you removed web services from your printer before starting this process, after the printer has connected to your network, re-enable web services on your device and add your printer to your account on HPePrintCenter.
If you did not remove web services before setting a manual IP address and are still having connection issues, remove and re-add web services.
In some cases you might need to add the printer to your computer’s Printer/My Printers folder again, after you set the new fixed IP address.   If you have problems printing to your printer, simply use the option to add a printer, select the Networked printer type, and complete the add printer wizard. You will not need to reinstall any printer software on your computer.

LaCie external hard drive keeps losing connection to Windows 8.1 computer

Hello all,
My LaCie external hard drive (Rugged version) seems like it keeps losing connection to my brand new Windows 8.1 laptop. The laptop is an HP Pavillion 15-p 133cl TouchSmart Notebook which I just got today. Basically, every few minutes, or if I nudge the external
a bit, the computer will seem like it disconnected and reconnected to the external hard drive in a split second and bring it up in the Windows Explorer. This external hard drive doesn't show any problems connecting to any other computer, but it has occurred
with 2/3 ports on this computer so far. I'm a bit worried, because I definitely DO NOT want the files on this external to get corrupted in any way. What should I do? Thanks a bunch.

may I know your external HDD model, to check which USB version to isolate power and cable connection issue
if this is USB 3.0 try to attached at USB 3.0 at your laptop, your laptop has 2 USB 3.0 and 1 for 2.0, for external HDD with USB 2.0 sometimes need more power / more than 1 connection, sometimes the power will loose
but since the trigger it will disconnect if you nudge the HDD, I suggest back up data to your laptop first, try to change with other data or power cable, try also update your laptop chipset
try to check with other device to isolate port issue
may I know if you are using other PC, did your external HDD also will disconnect if you nudge it?
contact your external HDD manufactured to get some suggestion

Why does my iPad2 suddenly keep losing connection on facetime?

Why does my iPad2 suddenly keep losing connection on FaceTime and tries to constantly reconnect?

Does it happen anywhere that you use FaceTime or only in your home WiFi network? If it happens with your home network, have you tried power cycling your router? Unplug it for about 30 seconds and then plug it back in.
Turn WiFi off and on in the settings. Reset the network settings.
Have you tried any troubleshooting steps at all?

Why does my mouse keep losing connection every minute

why does my mouse keep losing connection every minute, its not the batteries

I'm having the same issue. Every so often it loses connection then re establishes. This goes on repeatedly.
If you change batteries while the computer is still active then it takes for ever to re connect.
Can't wait until someone replies to your question.

Why does my mouse keep losing connectivity

My magic Mouse (came with the system) keeps losing connectivity. It seems that whenever the mouse has a period of inactivity such as when I am using the key board, it loses connectivity and I have to double tap it (two fingers) to get it to reconnect. Battery is >80%. Is this normal or is there a setting that can insure it stays connected? I appreciate any advice even if it is I have to put up with this annoyance. Thanks.

BDAqua
Thanks for the response. My WFi is a Linksys E2000. Because of the number of messages in the Console I will have to wait until the next time I lose connectivity and then check for messages in Console to see if there are any clues to what is going on.

Deskjet 3520 keeps losing connection to Mac

Last night, I installed an HP Deskjet 3520 printer to use with my desktop Mac (which is using OS Yosemite). I have an etsy shop where I sell prints of my illustrations, so I often have to print out multiple files in a row. When I installed the driver last night, I was able to wirelessly print the test page, but after that, I could not print wirelessly. Instead, I used the USB connection, which worked fine. I printed a round of prints and everything worked fine.
This morning, I need to do some more printing, and my Mac reported that there was no connection to the printer (even though the printer was connected via USB). I deleted the printer from my Systems Preferences Printers and re-added it, and I was finally able to do my printing (still not wirelessly).
Now, tonight, I have tried to do more printing and the Mac reports that there is no connection to the printer, USB or wireless. I tried deleting from Systems Preferences and re-adding again, but that didn't work this time. Then, I tried resetting the printing system, uninstalling HP, and re-installing the driver. Now, I'm at the part of the installer where the device needs to be configured and I am receiving the message:
Device Not Reachable. The wireless network settings were successfully downloaded to your device. However, your Mac was unable to locate the device on the network.
I don't know what keeps going wrong! The little screen on my printer says it is connected to my wireless network AND I am still connected via USB so I don't know how the device would not be reachable. I also don't know why the printer would keep losing connection with the computer every time I need to start printing again. Please help!!

Hi @tylertot
This is in deed a little strange, but I'd like to help! Some of the steps I am going to offer are steps you have done, but I;d like to perform the following steps in the order presented to see what happens. Please give the following a try;
Leave the printer on and unplug the power cable, also unplug the USB cable. Restart teh Mac and then plug the printer power cable back in. You can also go ahead and reconnect the USB cable.
Reset Printing System - (I know you did this already, thus you know how, but here are the steps for others who may view this thread)
Click the Apple icon (   ), and then click System Preferences.
In the Hardware section, click Print & Fax/Scan. The Print & Fax/Scan dialog box opens.
Right-click (or  Ctrl  +click) in the left panel, and then click Reset printing system…
Click OK to confirm the reset.
Type the correct Name and Password.
Click OK to reset the printing system. The Print & Fax dialog box shows no printer selected
Note: This will remove all printers in the print and Fax/Scan, any printer removed can be re-added later by clicking the plus (+) symbol.
Repair Disk Permissions - I don't see that you have tried this yet, and this step might be crucial to resolving the issue.
On the Dock, click Applications, and then click Utilities.
Double-click Disk Utility.
Highlight your hard drive/partition on the left (by default this is "Macintosh HD").
Click the Repair Disk Permissions button at the bottom of the window.
Once the repair is complete, restart the computer and add the printer back.
When you add the printer, please ensure you are using the HP driver. You can add the wireless or the USB, or Both. If you ad both, I suggest adding a name to identify one connection from the other.
Select Add other Printer or Scanner
Select the printer you are adding and next to 'Use' you can the printer driver
You can see in the image above where the name section is, if you add both connection types simply add USB to the beginning of one of the names.
Adding both printers and naming them to help identify them helps when it comes time to print. When you print something you can choose the printer with the appropriate connection type. For example, you can choose the wireless driver ad if you get an offline message try printing again but choose the USB driver. If the USB one works you will know the issue is related to the Wireless connection, and if it doesn;t then the issue is related tot he operating system. Really this is just a proactive troubleshooting attempt in case issue arise in the near future. If you only want to add one connection type that is okay too.
I look forward to hearing from you.

I have an iPad 2 connected to airport express so that I can play and change music whilst I am teaching ballet class. Recently, I keep losing connection and the airport express gets quite hot. I have alway used Archos but changed to Apple for reliability!

I have an ipad 2 with airport express that I use to play and change music whilst teaching ballet class. Recently, I keep losing connection and the airport express appears to be getting quite hot. I did use Archos but changed to Apple for reliabilty! Can anyone help or should I just buy a new airport express.

I agree that it's probably interference. Only other possibility, since you mentioned it, it overheating. Is the express situated so that it is well ventilated? That is to say, not buried under other equipment and laying on its side? What does the status light do when you lose connection?

Unable to connect to eprint server

Though it had been working fine, my photosmart b210 can no longer connect to eprint server. iPad and iPhone can not find printer. Wireless network diagnostic by b210 shows everything fine.

Thanks for the reply and sorry for the trouble. Check out this document which goes out troubleshooting the iPad no finding the printer. There is two different sections, one for AirPrint and one for the Home & Biz app.
'The Printer is not Found,' 'No Printers Found,' or 'Printer is Offline' Message Displays on the iPa...
Be sure to response so I know if this resolved your issue. Good luck!

2008 Mac Pro keeps losing connection to my Plex Blu-ray burner

my 2008 Mac Pro keeps losing connection to my Plex Blu-ray burner. It is installed in the second optical drive bay. If I power down, pull the connections to the drive and re-attach, the drive is again recognized on boot. A day later, no drive found. The first optical (top bay) drive never loses connection. Any thoughts?
