I thought I’d post this guide after spending a whole afternoon trying to overcome a similar problem – ‘How do I get my HP Deskjet F4580 printer working wirelessly again on a Mac after I’ve changed over to a new router?’ Or as some people have been searching: ‘My wifi HP F4580 won’t connect to my mac’.
The problem I had, and I expect many others still have, was that I upgraded my router which meant the printer no longer recognised it. All I was getting was that infuriating blue blinking light telling me it couldn’t find the old router’s network name and password. So how do you change the printer’s wireless network and password to your new router’s settings?
In this explanation I’m assuming that you’re using either Mountain Lion, Mavericks, Yosemite, El Capitan or Sierra (thanks to all the people who have commented that it works on these OS) and don’t have any installation CDs for your printer (which you don’t need now as Apple Software Update would have installed your driver).
If you access Printers & Scanners in your system preferences and go to the Deskjet utility there’s no option available to change these settings. After looking around I finally found this explanation on the HP forum but it was well hidden. I’ll share it with you now:
- Reset the network settings of your printer by pressing and holding the Cancel button, then after 3 seconds press the wireless button.
- From your Mac click the WiFi icon and then click Join Other Network (some people have found on clicking the WiFi icon they are presented with the option of HPSETUP straight away. If so connect to that now. If not, follow the next instruction).
- Click Show Networks, select the printer SSID, it will be listed as HPSETUP or will include HP or F4500 within its name, then click Join.
- Allow 2-3 minutes to establish the connection. The blue light will stop blinking when it’s done. Mine did it within 30 seconds.
- Open Safari and click the Bookmarks icon.
- Click Bonjour and then click the printer name, the EWS page will appear. This is the admin page for your printer where you can change its settings. Make a note of the IP address in the URL bar if you want so you can access this page again at any time instead of using the Bonjour bookmark.
- Note: if there is no Bonjour option under the bookmarks, click Safari > Preferences > Bookmark and check the show Bonjour option.
- Back on the EWS admin page, click on the ‘Networking’ tab.
- Under Wireless (802.11) click ‘Start Wizard’ and follow the steps listed on the screen to configure the wireless connection. It will give you a drop down menu of the available wireless networks so select yours and then follow the instructions for inputting your new network name and password.
- Note: If you’re required to provide the Security type for your wireless network, you may click the WiFi icon, click Network Preferences and select the Wi-Fi network. Click Advanced and you will find the security type of your network within the Wi-Fi tab.
- Once you’re done inputting all the information you click ‘finish’ however the page may stall while trying to reload. It will give you a message on the page about this problem. Don’t worry, your settings have changed and you can carry on as normal.
- Once the Wireless Setup Wizard (via the EWS) completes, click the Wi-Fi icon of your Mac and reconnect back to your router again, now both of the devices should be connected to your router.
Once you’ve done this process, the printer will recognise your new router again. But your Mac won’t.
Go to System Preferences > Printers & Scanners and remove the printer in the list on the left by highlighting it and clicking on the minus symbol below. This removes the old printer from the Mac. Now go ahead and click on + to add the printer back. Your Mac will scan for available printers and find your ‘new’ printer with all its updated router settings. Once you’ve added this, you’re good to go.
Hope this helps someone.
