My HP Photosmart C4780 Wireless keeps disconnecting

• Photosmart C4780 wireless Mac connection failure

  I, like some others I've seen messages on, will have exactly the same problem with my HP Photosmart C4780 of wireless connection to my MacBook.  I just bought this printer a couple of days with a new iMac (which I have not yet unpacked, yet).  I decided to see if I could go ahead and get the printer works with my Macbook.  Here is a breakdown of the specs, measures and tests.

  1 MacBook OS X 10.5.8 (Leopard) running.

  2. software is installed.

  3. to set up a wireless connection, the "Device unavailable" error appears in a dialog box.  This is the same error that others have had.  He continues with... "The network configuration has been correctly transferred to the device.  However, to continue the configuration of the device in the network, your Mac must have access to the device... ».

  4. I can load the page HTTP for my router (a Qwest Actiontec M1000) and see the IP address of the printer.

  5. I can successfully ping the the IP address Mac printers.

  6. I cannot correctly load the HTTP page to the printer via the IP address and the view that it is different pages.  I can even change some of the settings, however, apparently never really complete updates.

  7. After talking with HP support for more than 90 minutes (after waiting on hold for nearly 45 minutes, not a joke), we arrived at the conclusion that the modem/router must be the cause of the problem.  So, I was told to contact Qwest to get help.  Furthermore, technical support had me through many of the same steps I've seen on other items (for example, reset the printing system, uninstalling and reinstalling the software, reset my router, etc.).

  8 next, before calling Qwest, I decided to see if I could get the printer runs on Windows.  Under WinXP SP2 on a platform completely separate (but), I was able to install the software correctly and successfully a wireless connection to the printer.  I rebooted the machine Windows several times and disconnected the power to the printer just to make the connection is when it was re-powered and rebooted.  And Yes, everything works perfectly on the Windows machine.  It tells me there is nothing wrong with the router (with a possible exception, which I will speak in a moment).

  9. given that the installation worked in the windows box, I decided to call HP.  This time I isn't that hold it for about 20 min.  I told them what the results were in the Windows world, and we proceeded to work on this issue with the Mac for about an hour.  We have made some of the same things, as for the first phone call, in addition to a few other checks.  It simply seems that software on Mac just cannot see the printer, which means that the HP software will be unable to see it as well.  It's very weird because I can still ping and also set up its Web page (on the Mac and Windows machines).  Now technology seems to think that this is a problem with Mac OS because it certainly works with a different OS with the same router.  I'm leaning toward the same conclusion as well.

  10. now for the question of the possible router I mentioned earlier.  I saw in another post where someone says hello.  Something the Actiontec only modems no routing of packets used by Hello.  I have absolutely no idea what the Hello devil is.  I tried to do a little research on this and am still confused as to what it is and what it does.  However, if Hello is something specific to the Mac and has nothing to do with the router itself, then it seems to me that the router had no knowledge of Hello (and certainly would not care).  Therefore, the ability of routers delivers packages for different platforms should not be affected by this Hello thing.  However, this does not mean the packets are not getting lost once they arrive at the Mac because of Hello (again, not knowing what it is).  Now if that's the case, then it seems to me that the problem would be with the Mac (in conjunction with this thing Hello), not the router.

  11. other positions reported this same problem wireless with this same printer using OS X 10.6 (Snow Leopard).  If this is true, then when I finally unpack my new iMac, I expect to have the same problem... we'll see when I am near to it.  If he did not have this same problem, so maybe there is hope if I upgrade my MacBook to Snow Leopard.

  If anyone has any other light to this problem, please let me know what might be the underlying issue, and how can I fix this (if someone already has).  Thank you.

  Finally, problem solved!  Here is the solution, if someone else is facing a similar problem.

  Since I found the IP address of the printer on the Web page of my router, I went in "Print and Fax" system preferences.  From there, I clicked on the sign "+" to add a printer.  Nothing appears in the default tab.  So, I went to the IP tab.  From there, I selected the Protocol for the "HP Jetdirect - Socket".  In the address field, I entered the IP address of the printer.  After a few moments, the printer was found and the field "Print using" is automatically filled with the print driver.  I clicked on "Add", and low and here's the printer now appears in my list of printers.

  The second representative of HP I was working with me had to go through this same series of steps with one exception.  Never, we put the Protocol field.  He was left as default "Line Printer Daemon - LPD".  When this was done, nothing ever appeared.  So, I think that the trick was to change the field Protocol, as shown here.

  I hope this helps those who have a similar problem.  Good luck.

• Photosmart C4780 wireless installation under 10.6

  Well, I have a Photosmart C4780 printer, and I try to get connected to the network. I need to connect it wirelessly because that cable of three feet it came with just do not cut it.

  I have no idea how to connect it. I see nothing on the networks in the software of the printer, and the printer itself menus are cryptic and buggy.

  Any statement of Mac, I can find is for older versions using the real HP software. From what I understand, if I'm on Snow Leopard, I'll use drivers and the software I already have. The sole instructions of Snow Leopard I can find hidden only setting via the USB port.

  Help would be greatly appreciated! Thank you.

  Download the latest version of the software HP here

  Run the program and first have the USB cable connected to the printer, you will come to a point in the configuration where you will be asked if you want to configure the wireless printer.  Confirm the configuration wireless and just the follow through.  You will need to know your wireless network security settings and benefit that your Mac is on the wireless network that you want to use with the printer.  It's pretty simple.

• Beats wireless keep disconnecting from my iPhone

• Photosmart C4780: connection for Photosmart C4780 wireless

  I spent two hours through the simplistic menu of the printer, only to print copies of the Configuration Page of HP network and Test wireless network without success reports. I think I made all the necessary steps... such as the restoration's default network.

  "Your HP printer cannot find your wireless router. Check that your wireless router is powered. Make sure that your network printer HP (SSID) name exactly matches the network name (SSID) wireless routher yout. If they do not exactly match, run the installation of the wireless network to set up your HP printer.

  Well, I have entered my IP address of the router as the url of the browser and connected to my cable account, but was not able to change the SSID.

  I also looked at the Youtube page help HP and on discussion forums and tried to use the suggestions.

  One who seems to be similar to my situation is this:

  http://h30434.www3.HP.com/T5/LaserJet-Printing/driver-for-HP-Photosmart-C4780-for-OS-X-Mavericks/TD-...

  I, too, can't find "the HP network configuration.

  I also downloaded the Printer Driver HP Patch for my OS.

  At this point, I'm not sure that I can do. The other suggestion on this page was to find a friend with a PC. I phone my mother on-site, running Windows 10. I also downloaded its respective driver. I don't know what I should do next. Any help would be appreciated.

  I have a D-Link router, and I can provide additional information, such as IP, WiFi SSID, pine, etc., if necessary.

  Hello

  You need to press on you first, WPS option on the printer.

  Please, try this and let me know how it goes:

  1. On the printer control panel, press the button next to Scan, and then press the button next to the Wireless Menu.

• Is it possible to connect the HP Photosmart C4780 Wireless printer without USB cable?

  Hello

  My family and I recently moved and while moving, something inevitably get lost or left for account.  I am fighting to get this printer and will so I don't have to bother people at the front desk at school to print my documents for me.  I have lost/misplaced both the HP Photosmart C4780 printer software disk and the USB cable.  I have no idea where these things are and have not found them within two months, we've been in the new House.

  I solved the issue of the loss of the installation disk by downloading it from the HP site.  My problem is now getting beyond the USB connection and get the currently installed software.  Because I run on a MacBook Pro, it always tells me that I need the USB key to continue the installation.  I'm on a Verizon Wireless router, and I even tried to find the printer on my wireless network with no luck.

  Help, please!

  Thank you.

  It's the type of cable you will need (ignore the color of the cable, the ends are the important part).

  

  Have a new router is not a problem, but remember the SSID and password wireless exactly, otherwise it will not work (if you decide to try Method 1). It's a bit like "trick" your printer into thinking that your new router is your old a long enough to configure the network settings for the new (desired).

• Photosmart C4780 wireless do not print wireless

  The basics - old iMac dual core, new Macbook (both with Snow Lepoard 10.6.1,) relatively new Airport Extreme, new printer 'Wireless' Photosmart C4780.

  Installation/set up progresses to a point, then I get the message "network unavailable. The selected WiFi network is not in range of the aircraft. "The 'device' the C4780 sits 3 feet between the router and showing the strength of the signal higher of all networks in the region.  [BTW - the new Macbook would work wireless from time to time until people e-mail tech support HP's suggestion, I have made an adjustment to the configuration of the router.  Now it works again even if the router settings are returned to their default value.  When you attempt to print wireless from a computer, the printer says it is offline.  I talked to Apple support and they advise that if I can get the IP number of the HP printer, I should be able to configure the printers to work.  HP technical support 'Chat', explains the IP number is assigned by the router.  I've given up o HP Webcam live tech support after being on hold for over a half hour, twice.  HP support 'Chat' is almost exclusively oriented Windows and they send me to technical support of HP "e-mail", which sends an email per day reiterating I already took action.  Sorry for the rant, but this forum is my last hope.  Can someone help me? What can I do to get this working?

  Have you deleted and added the printer in the print queue? Let's try it:

  -Sys Prefs, Print & Fax
  -Select the printer in question and click the sign less down the list
  -Select the sign and add it again.

  If this does not work, do the same thing, only instead of the second stage, right (control), click the box of the print queue and select Reset Printing System.

• Photosmart C4780 wireless set in place the question

  Hi all

  I tried to implement the Photosmart C4780 to print on a wireless network. I have a pc running Windows XP SP2. When I go through the process of configuring the network device it seems to pass a number of steps with no problems before you throw the following: "the printer attempted to join the network but does not receive any data. This may be caused by MAC address, filtering... "I checked the router settings, router is a Netgear Wgr614 and MAC address filtering is turned off.  I have a number of other devices connected to the network and all have very well connected without tinkering with the configuration of the router.
  When I run a wireless network test, she spends the first 5 criteria (Wirless on, working wireless, found network name, security, printer settings in line with the wireless router settings) before failing on the 6 criteria (filtering on).
  Any ideas...

  Have completed using the USB connection and which works very well but I would like to run without thread if poss.

  Thank you for your help. Neil

  It's fixed now, everything worked Ok once I changed the WEP authentication type router "Shared key" setting to "open system".

• Linksys AC1900 Smart Wireless keep disconnecting?

  Hello

  • I installed 2 routers AC1900 Linksys and E1200, my Local network is running on AC1900 at least 50-75 devices on the same time.

  3. Prioritization of media
  4. Wi - Fi Protected Setup (previously it was ON, but the problem exsits).
  5. MAC filtering
  6. DMZ
  7. DDNS

  The firewall is on, with default rules.

  NOTE: I have 2 connections separate intenert (24 Mbps) for each of the routers.

  Thanks in advance

  for the two of you, which version is your hardware and what version is your firmware? If they are material ver 1.0 so make sure that you use the older version of the firmware that ends with 156465 and not the version which is 158863. This version is only for version 1.1 of the material. You can get the 1.0 version of the linksys web page but remember to select hw 1.0 in order to see it. Once download you the install from the browser page and your abandonment should be better

  You can also disable cut through redirection on the login tab admin page and see if that helps. If please post back and let me know. I want to talk this problem to their guys of dev

  Have you tried to update the driver WLan? If this is not the case, do it!
  Try to download the latest version of the driver. If the driver Toshiba page does not the latest one please check the card WLan manufacturing site; Perhaps Intel or Atheros.

  Another clue
  Have you tried to disable encryption and to test the performance? It and if anything does not work you can set it back again once!

• New password Wi - Fi and the need to upgrade the configuration on HP Photosmart C4780 wireless

  We got a new Verizon FiOS router through an upgrade and now have the new network name and password WEP. I use MAC OS X 10.10 (Yosemite) and does not know how I can change settings of the printer wireless to match the new router information. I tried to uninstall and reinstall the printer on my computer, even re-installed the software, but nowhere he gave me the opportunity to enter into new free wi - fi connection settings. Any ideas?

  And the FiOS router does not support WPS, so I can't use it, unfortunately. Thank you!

  Hi @8eleven5

  There is! If it already has the software installed on your mac, connect the printer using a USB cable and open the HP folder, inside the Applications folder. In the HP folder, find ad open peripheral utility then the HP installation wizard. Run the wizard and choose the option to Setup wireless via USB.

  If she didn't already have the software installed, use the following link to install the software, plug the announcement of cable USB Setup will guide you right to the installation wizard.

  Once the software has set up the printer to the wireless network, simply add the printer to your 10.10

• Problems connecting my computer to my wireless network when Photosmart C4780 is connected

  Hello

  I recently bought a new printer Photosmart C4780 wireless. It works fine via USB, but I seem to have problems when I try to set up with my router.

  Here's what happens:

  First of all, I run the Setup on the CD supplied with the printer (while connected wireless to my network).  I am going through the different steps and after Setup finds my network settings to give to the printer. After that, the Setup program tries to find the printer on the network.  It goes very well for about 4 or 5 seconds while the printer connects to my wireless... but then, once the printer connects, my computer disconnects causing an error Setup can not communicate with the printer because I'm not connected to a network.

  What is going on?

  If anyone can solve this problem for me, that would be amazing and be a great help!

  Chuck

  I'm sorry to say this but there are problems between SMC routers and HP printers.

  Search this forum MUCH info on the subject.

• Once I connect my Photosmart C4780 to my wireless network, I lose everything internet.

  My router is a Netgear WNDR3700v3 with firmware version V1.0.0.22_1.0.17.  I can get internet to work on my HP pavilion dv7 with windows 7 64 bit, my smart sony TV, my xbox 360 and a phone that I connect to my wireless router.  The second, I configured my HP Photosmart C4780 wireless router I lose internet on all devices.  I can connect to the router again but can't get out to the internet. What would be the printer could prevent me from accessing internet?

  We will set an IP address of the printer:

  -Print a the front of the printer Network Setup Page. Note the IP address of the printer.
  -Enter the IP address in a browser to reveal the internal settings of the printer.
  -Choose the network tab, then wireless along the left side, then on the IPv4 tab.
  -On this screen, you want to set a manual IP address. You must assign an IP address outside the range that the router sets automatically (called the DHCP range). If you do not know the range, change the last set of numbers (those after the last '.') 250
  -Apply the subnet 255.255.255.0 (unless you know it's different, if so, use it)
  -Enter the IP of your router (on the Page of the Network Config) for the gateway.
  -Enter for the first DNS 8.8.8.8 and 8.8.4.4 for second DNS.
  -Click 'apply '.

  Now, stop the router and printer, start the router, wait, and then start printing.

  After that, you will have to redo 'Add printer' using the new IP address.

• HP Photosmart C4780: Photosmart printer keeps going offline

  HP Photosmart C4780 randomly disconnects.  I connect the printer cable to my Macbook Air running OS X Mavericks. (It allows to print wirelessly, but I had so much trouble now 'online' I dropped and now just plug in when I need to print.) Printer will connect and print for months in a row, then all of a sudden he's going 'offline' and I can't do online. I restarted the laptop and printer but did not help.  Why he continue offline... and how I get it online? THX

  THX... printer works again.
