Cannot connect my Photosmart C4780 to my network wireless (home)


I searched this forum and tried to solve my problem, but none of the elaborate suggestions.

I have a Photosmart C4780 and am under OSX10.8

Recently, our internet provider changed our wireless router and our SSID. As a result, the printer that is connected to the original network and properly functioning has stopped working. I tried to connect the printer to the new network, but failed. He said now that the printer is connected to the hp network (something) and I can't change it for the new SSID.

Could you please tell me what to do? I have installed the software mentioned in the HP website, plugged the USB cable into the printer to try to set it up, but it says that the printer cannot find any existing network (although I'm next to the printer and connected to the intended network wireless)

Fact a little kind of hard-reset on the printer can be a good strategy? How can he do?

Thanks in advance


PS: The printer works correctly when printing via USB

PS2: It is not an option to return the SSID of the router to the previous


Hi @pedroa

You say "I have installed the software mentioned in the HP website", but there is no software for the compatible with 10.8 c4780. Mountain V10.8 OS X Lion: installing and using the printer on a Mac with the Mountain Lion.

As you know, this printer has not a wizard wireless version in the front panel instead us would typically connect the USB cable from the printer to the computer and run the installation wizard.

Because you have 10.8 on Mac, and it there is no full feature software and drivers, you won't be the configuration wizard, to configure the printer. You may be wondering now, well how can I set up then?  Good question, we will restore the default network printers and the printer will have its own IP address designed for whats called an Ad-Hoc connection (wireless router). We will put the computer on the network printer and then print a report to get the printers IP address. At this point, we can access the built-in web server (EWS) and run the wireless from there. Once the printer on the network with the router, we can put the computer on the network and vuala that the printer and the computer will be on your network.

To restore the default network settings - since you have done this before I guess you know how, but for others who can see the message, here are the steps

  1. Press the wireless button
  2. Select wireless settings
  3. Scroll and select default network.  Press Yes to recognize
  4. The radio turns off (the blue LED turns off).  You may need to press the wireless button to turn on wireless

Put the computer on the network printer (temporary)

1. click on the symbol of the airport on the upper left side of the screen Mac
2. choose the network looking compared to the printer (we could say a variant of the name of your printer or HP setup) - it may take a few minutes to make it appear

Print the wireless network test - wait a few minutes to make sure the computer have established an ad hoc connection, otherwise the report will not have an IP address

  1. Press the Scan button (it also the wireless menu button)
  2. Select wireless settings
  3. Testing wireless access, then select.

The wireless network Test prints, search and note the IP address.

Open a browser (Safari) and enter the IP address in the URL (address bar).

Click on the network, on the left tab, click on wireless or 802.11.

At this point, we are looking at fore 'start the wizard' should be on the right side.

As soon as we will have to set up the printer to your network, you can put your computer on your own network.

Now you can add the printer in system preferences and print

Please let me know if that fixes the problem, thanks.

  • Wireless laptop cannot connect to Photosmart C5180 printer on network

    I recently got a new computer, which is the main connection to our home network.  We have a laptop and a Photosmart C5180 printer.  I can't get the wireless laptop to connect to the printer, even though I have the shared printer on the pc.  I have the printer connected to the pc via a USB cable.

    I see the printer shared and available on the laptop, but get the error message when you try to print.

    Does anyone know what I'm missing that will allow me to print from wireless laptop?  It worked until I'm the new pc, so I know I'm missing something.  Should the laptop have both installed printer software/drivers?

    Yes, the printer directly connected to a router with an Ethernet cable will be the simplest solution.

    Yes, all computers will be able to access the printer on the network as long as they are connected to the same router (Ethernet or wireless, regardless).

    He shared from the computer and the printer connected to a computer with a USB cable are not a real printer on a network.  This creates what is essentially a print server and the computer with the USB connection manages the interaction of this printer with all the devices on the network.

    A USB connected printer sharing can be done, but it's a lot more work that the printer is connected to the router with an Ethernet cable.

    It's really a lot more work to set up the printer with a printer shared over a network connection USB method true when it comes to do this with Windows 7.

    Windows XP made it incredibly simple, but he was not very secure on a network.  With Windows XP, all you had to do was to share the printer, and then install it on another computer.

    With Windows 7 on both computers, you must configure a homegroup, enable file sharing and printers (disabled by default), share the printer and install the printer on the computer client / remote.  In addition, this method will require the host to be on anytime for remote printing machines.

    The printer is connected to the router with a Ethernet means that the functionality of the printer depends solely on the router being on (most are on 24/7).  Computers will print regardless of the other computer either on or off.  There should be a shorter time in the impression that a computer is responsible for printing rather than two computers.

    Again, I will be more than happy to help you set up with the method USB shared with two Windows 7 computers if that's what you want.  You find that it is much easier to use the Ethernet connected method to be simpler and more efficient to print well.

    If you want, here's a little more information from Microsoft on sharing a printer between two units of Windows 7.

    Setting up a homegroup

    Activate the file & printer sharingand sharing the printer on a Windows 7 computer

    As long as the printer & file sharing is enabled and two Windows 7 computers are in the same group of residential, you should be able to use the USB share method.  Without these two two options being Setup, it simply does not work with two Windows 7 systems.

  • Cannot figure out how to connect HP Photosmart C4680 to my network without Setup CD

    Currently, I moved to a new apartment and I am now trying to set up my HP Photosmart C4680 printer. I have problems connecting my printer to my network wireless with my MacBook Pro computer. The current version is 10.6. I downloaded and installed all necessary drivers and software from the Web site: HP's Web Site. When I go into the installation process he never asked if I want to connect the printer to a wireless network. I just blazes through the installation and said: "Congratulations!" You have successfully installed Photosmart C4600 series." I called HP and they said they can help but its going to cost money because my printer is no longer under warranty. I hope someone could shed some light on my situation.

    So I thought to it. My girlfriend and I just moved into an apartment together and I both are "identical" printers in my office. After a full day of trying to get the first printer to work, I looked at mine and saw a sticker on the front of it wireless. I watched his and realized that his is not the sticker wireless. Then I looked at the model numbers and realized his is a HP Photosmart C4680 and mine is a HP Photosmart C4780. So what I did, I used his MacBook Pro (Version 10.6.8) to download the software for the HP Photosmart C4780 from the HP Web site. I have connected feel to the Mac via USB and begin the installation. During installation, it asked if I wanted to set up the printer to a wireless network. I said "Sure!" He asked for the network I want to use and then set up the printer to the network. Then I had to go to "Print & Fax" in "System Preferences" to add the printer. After that, I was ready.

  • 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 (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 and 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.

  • 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:

    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.


    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.
  • Cannot connect HP Photosmart 5515 series wireless on my laptop

    Hello, I use a hp pavillion g6 and im trying to connect wirelessly to my printer Photosmart, 5515 but im having problems with the computer was implemented wirelessl room in my house for a while and me can print quite easily using my Iphone but I cannot set up wireless. He invites me to enter my IP address I do, but then he repeats just cannot connect I also tried to use hostname, but that does not work either please help the two devices are connected to the internet even and I checked they are running both on the same IP address

    Thank you

    Try to go in the tools on the printer and to restore the default settings of the network.  He's going to knock it out of the network briefly but then set it back up as if it were the first time.  You meet intellectual property conflicts, and it is a first step in troubleshooting.  It can change the IP address of the original one, as well, but that is not a bad thing.  Let me know how it goes.

  • Cannot scan HP Photosmart C4780, Mac OSX 10.9.4

    At the same time, I bought my MacBook Pro about 4 years ago and my HP Photosmart C4780. Recently I replaced my hard drive, so I now have the OS of Mac OSX version 10.9.4. I can always print to my RESUME, but I can scan is no longer. If I try to open HP scan, I get an error message. I tried to go to the--> Printers Scanners &--> scan system preferences, and everything seems to sweep but is not save to my computer. I looked at to download the driver, but it does not list my specific operating system... but lists "Mac OSX" which seems ambiguous for me (it lists specific versions up to 10.6). There is no option to download a driver, but there is an option to have a disk sent by post (paying), but I am unclear if this driver works with my version of Mac OS x.

    Are you sure?  Try to save it on your desktop - give it a distinctive name, so you can easily find it.

  • Problems connecting to a Satellite Pro 4600 for network wireless home

    My computer has a processor Athlon 64 x 2 4200 + and 2 GB of RAM, with XP2 Pro. I have a Linksys WRT54GS broadband router and connected with Virgin Media.

    My daughter gave me an old laptop a Satellite Pro 4600 with a 747 MHz Celeron processor, 384 MB of RAM and XP2 Pro has an Intel Pro/100 VE Network adapter. I set up a Linksys Wireless - G Notebook Adapter with SRX (model No. WPC45GX), so that I could use around the House. However when I try to connect to the home network, although he "finds" a list of networks, I am unable to connect and get an error message - "Windows cannot connect to the selected network (my home network). The network can be is no longer in range. Please refresh the list of available
    networks and try again. »

    I tried to connect with laptop computer in the same room as the router, but get the same message. In the Manager of peripheral devices, network cards, the two are shown and both work properly, but in the taskbar there is a red cross shown on the two icons, they say that a network cable is unplugged, but I don't have a cable network.
    The other tells me that the wireless is not connected.

    I presume that the adapter works as it can 'see' wireless networks, I used Lynksys support to verify that all router and adapter settings are correct.
    My wife has a new laptop and is able to connect to the home network with no problems.

    Please can someone offer advice or assistance.


    for some reason, you need to turn off your wired connection (cable) and use the client of the PCMCIA wireless network card. Maybe just the problem that your system can not separate the two network connections and gets an error it s. You should also visit the site Web of Linksys and download the latest driver and the customer for the card, so you can make sure that the software is up to date.

    Another good idea would be to visit and the support center for any 'knowledge base documents' which could probably solve the problem.
    As your machine is really old and no one is using PCMCIA cards more, you may wait a long time for an answer in this forum. Maybe you should check the site from linksys for a support section. Maybe they could help you...

  • Unable to connect my P1102w printer to my network wireless (using Mac OS 10.6)

    I have a home network wireless vanilla (D-Link to a cable modem) and a MacMini running OS 10.6.8. My Mac laptop and 4th. GEN iPad work seamlessly. But my attempt to long hours to connect my new HP P1102w network was totally frustrating, despite a careful study of the documentation pdf, device/self test the printer configuration sheet, sailing on this forum, I'm looking at a slew of videos YouTube/HP and following all sorts of directions.

    The only consolation is the printer works fine on USB connection.

    Here are a few questions I met and that stopped me in my tracks:

    Carefully following both instructions pdf and video operating instructions online to HP, I get by step 6 w / no problemn. but then I go to step 7, which says:

    "Under the Mode of Communication , Infrastructure -click, select your network SSID from the list of names of the network (SSID)" and then click on the button. ""

    Problem is that there is nothing in this window. What I see is a State of the Wireless: enable or disabled (according to choice). And even if I try to select enabled, happening right now for people with reduced mobility. Aside: I note that the printed instructions show a copyright date of 2011. It's ancient history in the world of the CPU.

    Other issues: the single IP address I can find for the printer is the IPv4 address, but it is only for direct printing Configuration. What is the IP I'm looking for?

    Address of the printer hardward, I suppose, is your MAC? Boy, I sure could use better use of language here.

    So, needless to say, I'm stuck. It seems that it takes THAT hard, but so far nothing that I could find on the HP support or forums seems to help. Thanks for any advice you can provide.

    PS. I wouldn't go back this printer because I am a lover of HP printer, two decade, but alas, I might have if I can't find a solution.

    Dear Gemini02,

    Thanks a lot for your helpful answer. It seems very complete, and I'm happy to give it a status of resolved problem, although I have not yet tried.  The reason is, one day before receiving your message, I benefited from technical support from HP that came with the guarantee of my printer (Oh!) I would have called them first before going on the forums. Lesson learned) and they took me in hand.

    I quickly reached a support person surprisingly knowledgeable and helpful tech (work of the night in Manila, PI shift), and I quickly accepted allow access remotely to my Mac and printer. For much of the next hour she practically held my hand as she walked through a fairly complex set of steps (very similar to yours) and here!, the problem has been resolved. She later sent me the steps she helped me through, as follows:


  • After the HP update cannot connect to the Internet using my ISP wireless

    I have a HP Pavillion15 Notebook PC, Prod #: E7C83AV using Windows 8. Hp yesterday made an update, and subsequently, my computer does not connect to the Internet, using the same network wireless ISP.  Only way I can get Internet is to use the DSL unit to the computer USB cord.  I had a "Configuration for Invalid IP (106)"

    My ISP is still in my system with the same password, and I can't find any reason why it does not connect.  I have all the correct lights on my computer & the DSL unit.  I have not contacted my ISP, do not know what to say "After HP did an update, your service will not work?"

    Tonight I tried to get help from HP, big whoopie, even when I'm in warranty for 9 months, I was transferred to HP/SmartFriends, who told me that I had to pay for the assistance.  It won't happen!

    I don't know what to do now, I'm not very computer savvy and if HP won't help, do not know where to turn now.

    I'm fighting mad now!

    Someone please help.

  • establishment of a network wireless home

    That's what I have:

    -2 laptops from toshiba with wireless cards
    -a point of access to toshiba
    -two of them are connected to the internet (dsl) via the wireless access point

    That's what I want to do:

    -share files between two laptops

    What should I do?



    There may be different ways to solve this problem.
    What I did at home was to
    (1) establish a working group name - for example the House. Fix all units you home to this working group.
    (2) on a machines to share a folder with read-only access (there is a guide in WinXP that will show you how do it.) You can start it if you unroll the contextmenu of the folder you want to share).
    (3) set computer names that are human. Windows normally gives really strange names, but if you have 1 Toshiba Satellite P20 and Toshiba Tecra M1 1 I give the P20 "P20" name and the idea also for the M1 "M1". Or if you use only the P20 and Uncle Bob the M1, culd you name your machine 'My computer' and the machine of Uncle Bob "Bob."
    4) both units will have to be restarted if their names and / or working groups are changed.
    (5) in the address bar of the browser, type the address of the other machine (the one that has the folder that you want to watch). For example:
    \\M1\ (press ENTER after the last------)
    You should be able to see any file or the other that the other machine.

    Tip: If you have problems see each other, make sure that you're both on the same net. I have problems of hade with that and not understood why we cannot see all the units in my house until I discovered that a neighbourgh also have a wireless connected to my missing unit.

    Hope this helps you.

    I have no idea what password you need, but usually, you have to set the right permission on the folder that you want to share on the network.
    I connected my two computers (both with Win XP) with a crossover network cable.
    Then I put the same name of working group on both computers and manually assigned IP address; IE: and
    Then, I selected the folder-> properties-> sharing tab.
    Here you can set the permissions.

    Using the WiFi network, you must set the option for * Ad-hoc network.

  • Is it Possible to connect HP Photosmart C4780 to FiOS without CD?

    When I arrived at the origin of my printer, I have Verizon DSL and haven't had no problem setting, the printer via the software CD. Since I spent to Verizon FiOS, but my sister lost the CD. How can I connect my printer to FiOS without the CD and then connect it to my laptop? I have a MacBook Pro (OS X 10.9.1) Mavericks running - any help would be greatly appreciated. I wish I could print wireless again!

    Hi AJoyner,

    You do not have a rare problem.  You must use the software on the CD for the printer connected to the network.  You may not use the software on the CD with OS X 10.9.1.  Once the printer is connected to the network, you can use this document to install the printer driver.

    You can use a Windows or Mac running a version of the OS that is authorized by the CD.  The Windows driver can be downloaded and used.  But you would need to use another computer to get the printer on the network and then it might work wireless with 10.9.1
