Unable to find wireless network on Photosmart C4780 on MacBook Pro running OS X 10.10.3

I have been successfully using a Photosmart C4780 on my wireless network for a long time. I had internet issues and the network name was changed. Now I can't print wirelessly. Tried reinstalling the software, but the program quits just before set-up.
Help!!

Hey there @physiocan!
Thank you for posting on the HP Forums!
I should be able to provide some suggestions that may get your Photosmart C4780 reconnected to your wireless network. Due to the age of the printer there is no full feature software and driver developed for Mac 10.10. Your printer requires the HP full feature software to setup the wireless through the USB cable. Once the Wi-Fi is setup then the USB cable can be removed. To reconfigure your printer to the new network name you will require a computer running the Windows operating system or a Mac with version 10.7 or lower.
Please post back and let me know! You will only require another computer for the Wi-Fi setup. Once the wireless is setup then you should be able to add it to your Mac 10.10 using the Apple Airprint drivers built into the Mac operating system.
Thanks again for posting on the HP Forums!

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Can't connect wirelessly HP Photosmart C4780 to MacBook Pro OSX 10.8.2 Mountain Lion.

Hi!
Didn't know exactly where to direct this question in the Apple Community so I chose Airport. To everyone, thanks in advance.
I’m really desperate. I’m a big Apple fan. I have two Apple MacBook Pro laptops with Mountain Lion software. I also have an Apple Airport Extreme. My HP Photosmart C4780 printer was also purchased from Apple. Anyway, my Internet service is AT&T. AT&T just upgraded my service with a new modem/router (AT&T U-Verse). Prior to the conversion, my wireless printer connection was working perfectly.
Now can’t print wirelessly. For your information, everything is connected via Wi-Fi. The AT&T technician stated that I no longer needed my Apple Airport Extreme, so it was removed. Naturally, after the tech leaves, we find out the HP printer wirelessly no longer works. Thinking that removing Airport Extreme may have been the problem, I reconnected it to the AT&T modem/router, however no change.
This appears to be an HP printer problem. I went to HP community support with the information below but I have received no solutions outside of buying a new printer.
“Ran the HP wireless network test report and it states that HP printer can’t find wireless router and to verify that the HP printer network name (SSID) matches the wireless router network name (SSID) exactly. The Diagnostic Summary in brief: Wireless On & Working & Security – Pass; Network Name (SSID) Found – Fail. Nothing else under diagnostic summary ran. Under Configuration Summary: It shows old SSID name and Mac Hardware Address but no IP Address.
Next ran the Network Configuration Page and everything is enabled except the 802.11 Wireless. It shows status – disconnected. Under general information it states the following: Network status - Offline; Active Connection Type - None; URL(s) for Embedded Web Server – http://0.0.0.0.”
To be straightforward, I’m no computer tech so I don’t know what this means or where to find. The AT&T tech provided me the new SSID Name and a wireless key number but that’s it. Also I uninstalled and reinstalled via USB. The HP message states can’t find router. At this point, I’ve tried everything to reconfigure without success. If I need to make these changes via Airport Extreme Utility 6.0 not easy to find not that I know what I’m doing.
Most importantly if I ever get wireless working again, do I still need Airport Extreme connection or is the AT&T U-Verse modem/router sufficient?
Any direction or help is greatly appreciated. Thank you for listening.

Thank you for your prompt response. I'll be honest I'm a retiree and a newbie to all of this stuff. I don't even know how to do a thread. (Embarassing) This is my first ever contact with the Apple Community so I'm slowly trying to figure this out as well.
As to your thread request, I'm assuming you want to read my post with HP. Not knowing how to thread, I've copied it below.

Re: Can't connect wirelessly HP Photosmart C4780 to MacBook Pro OSX 10.8.2 Mountain Lion.
I finally figured it out! (Sorry that I'm replying to my own posts btw, but I want to post the solution for anybody else with the SigmaplusEOL1 problem). If you have the SigmaplusEOL1 as your SSID when you print the "Wireless Network Test Report", you do NOT need to return it (I know that's hassle for people). To fix the problem, follow these steps.
1) Unplug your printer.
2) Go to your router's IP address (like 192.168.1.1 or whatever it is for your router).
3) Change the SSID of your wirelss network to "SigmaplusEOL1".
4) For the Security option for your wireless network select none (so that a password is not required to access your wireless network).
5) Power your printer back on and reprint "Wireless Network Test Repor". It should say "No problem found..."
6) The report should also have a the IP Address of the printer (under Configuration Summary at the bottom). Type that IP Address in your browser to get to the printer's settings page.
7) Click the "Network" Tab at the top.
8) Under the "Connections" header in the left pane, click "Wireless (802.11).
9) Click "Start Wizard" at the bottom right.
10) In the wizard, change the SSID and encryption (wep or wpsk) password to whatever you want your wireless network to be. So probably whatever it started out as before you changed the SSID to SigmaplusEOL1
11) Click "Finish" at the end. The page will probably try to keep loading but it won't because you changed the network settings of the printer. Just ignore that
12) Go back to your router's IP address and change the SSID and encryption password to whatever you changed the printer's SSID and password to.
13). Reprint the Wireless Network Test Report. It should say the SSID is the same as your wireless, and everything is good.
That's it. You should be good to go now.
Re: Can't connect wirelessly HP Photosmart C4780 to MacBook Pro OSX 10.8.2 Mountain Lion.
Thank you for your prompt response. This has been a totally frustrating experience. I’ve spent at least 8 hours trying to fix this. My HP problems and your initial steps were identical to mine. I am by no means a tech person and my computer tech knowledge is minimal. However I followed your steps to the best of my ability.
I did get the SigmaplusEOL1 message. I was able to get to Step 6 where the wireless network test report now reads – “HP printer settings do not match your wireless router settings.” So I guess this is a step in the right direction. However unfortunately the Configuration summary message for the IP Address reads – “Not Applicable”. (Note: changing SigmaplusEOL1 to network name knocked out my Internet access. Had to switch back to regular network name to regain access.)
I’m at a loss as to what to do next.   Without the IP Address is it possible to move forward? As I stated earlier, I’m not a tech person. As to your steps 7, 8 and 9, I can’t find them on my computer or maybe I’m looking in the wrong places. In System Preferences - Network, I have none of these steps. If you’re referring to Airport Utility, with the changes in Mountain Lion, these steps are no longer there. If you’re talking about Safari, Firefox or HP, now I’m really lost.
Finally, I don’t know if you can answer this or not. If I ever get wireless working, do I still need Airport Extreme or is the AT&T U-Verse modem/router sufficient?
Again thank you for your time and patience.
Re: Can't connect wirelessly HP Photosmart C4780 to MacBook Pro OSX 10.8.2 Mountain Lion.
Unfortunately I am unable to offer any further advice as I only followed the instructions listed on the other page.
Finally, as to having WEP enabled, I don't know. Don't even know where to look. The best that I could determine is that my security is WPA/WPA2 Personal.
I'm truly sorry about all of this. Thank you for your time and patience. After reading all of this and you change your mind, I would understand.

Unable to reconnect to wireless network after closing lid on macbook pro

After installing recent software updates, I am unable to reconnect to my wireless network when I close the lid on my macbook. It says that it is "connected", but I can't access any website, check e-mail or ping any external server.
I've never had a problem before, but now that I've installed software updates in the past few weeks I noticed the problem.
Anyone have any ideas?
MacBook Pro (Intel) Mac OS X (10.4.9)

which ultimately means apple didn't do enough testing before releasing the last patch
This is not always, and may not be, the case. What many don't realise is that many 3rd party developers stray from the 802.11 series specifications in an attampt to boost speed and get one up on their competitors. For instance D-Link, amongst others, use a short preamble setting by default in some of their routers to improve performance. However, this is non-standard and when it comes across wireless network adapters that don't support this then you have problems. They assume that their network adapters are being used for "maximum speed and compatibility". Whether Apple should or should not support a short preamble is another subject altogether.
However, I do agree with you in that Apple should put more work into their Airport software.

WiFi connection problem from HP Photosmart C4780 to MacBook Pro

I have an HP Photosmart C4780 that will not connection to my MacBook Pro. I am operating on the Mac OS X 10.6.8. It was working just fine when I was using my Apple Airport to project the WiFi in my house, but I recently bought a Apple Time Machine to back up my system and have a main networok and guest network for the house. When I switched to the new device, I am now unable to get my printer to reconnect via WiFi. I have downloaded all of the recommended software from the HP site.
When I click on set up wireless connect, it starts the first step to find the device and then I wait and wait. It just sits and spins and never finds the device. Yes I have it plugged in and turned on. I did not have any problems with this prior to switch the router for the WiFi so I am guessing it has to do with that, but I am lost on what to do. Please Help

Welcome to the HP Forums FlyGirl_1350,
I see by your post that you now have the Apple Time Machine and aren't able to setup the printer again on the network.
I can help you with this issue.
Follow these steps to restore your product's network default settings. This will clear out the old router encryption.
Touch the ATM button () next to Wireless / Scan.
Touch the ATM button () next to Wireless Menu.
Touch the ATM button () next to Wireless Settings.
Use the up and down ATM buttons () to select Restore Network Defaults, and then press OK.
Touch the ATM button () next to Yes to confirm your selection.
Make sure the computer is connected to the Main Network Name and not the Guest Network name.
Vice Versa. Sometimes the printer won't pick up the Guest Network to configure the wireless.
Run the setup again.
This document provides steps for setting up the printer on the network also.
Installing the Printer Software for a Wireless Network Connection (Using an Access Point).
If you are still having issues then power cycle all the devices in this order, power cycle the router, wait till it is back up again, turn the computer off and on again, turn the printer off and disconnect the power cable for 30 seconds, then reconnect it again.
If there is anything else that I can help you with just let me know.
Have a nice day!

Unable to right click shortly after start-up on Macbook Pro running 10.7.5

Hi. Earlier today I was using a Logitech wireless mouse, and suddenly I couldn't right click anymore. I was playing League of Legends and left the game and I still couldn't right click, neither with my Logitech mouse, or even the trackpad. I restarted the computer and when I logged in I was able to right click for a few seconds, then I lost the ability again. I am still able to use control + left click to access the right click functions, but am not sure what could have caused this problem.
I looked around and found old forum advice from as recent as a year ago, back to 2008. Those forums suggested I install a third party software, USB Overdrive, to search for certain files, which I have, or to delete particular ones, like AppleHIDMouse.kext, or com.apple.finder.plst. I turned off and on the double tap right-click function for the trackpad, and I tried at least three different mice, which work on other devices.
The only thing I can think to do is try to upgrade to Mavericks and see if that will have in it what I need to right click. Considering that I can right click until soon after rebooting, my best guess is that some application or process is running or stopping at start-up and causing my issue.

Very strange problem (no surprise to you).
I suggest you reset the SMC (and PRAM, if you are able). That cannot hurt and might help.

From about this Mac -Storage, my only HDD is full. there are 144 GB on Backups. How find and delete it. Macbook pro running Maverick OS X.

Hi, From about this Mac, my only HDD is full. When I have clicked and opened Storage screen when I've saw that there are 144 GB on Backups. I don't know which backup is it. and I really need help to find and delete it. I have Macbook pro running Maverick OS X.
I have a external HDD for time machine, but this backup I didn't know yet.
Please pleople... someone could help me? I'm in troubles.
Sandro

Linc Davis, According below: could I delete those snapshots from MobileBackups folder?   would it solve my problem? ( if I want not my HDD 80% full)     - Thank you a lot in advance.
Ordinarily, the best way to view your Local snapshots is via the normal Time Machine display, perquestion #15. If for some reason that's not working, you can see them via the Finder.
From a Finder menubar, select Go > Go to Folder and type /Volumes in the prompt, and select theMobileBackups folder.   You'll see the same structure as for Time Machine backups on a separate volume: a Backups.backupdb folder containing a folder for your Mac, which contains a time-stamped folder for each snapshot. Inside each of those is a folder for each disk/partition that was backed-up, containing the same folder structure as on the original, with the contents as of the time of the backup.
Note that nothing in the size column is meaningful (if you Get Info on the MobileBackups folder, for example, it will show the total amount of space on the drive it's on!   It will show dashes for the Backups.backupdb folder, or any of the dated snapshot folders).

HP Envy 5643 Cannot find wireless networks

Hi,
I purchased this printer a day ago and it connected successfully with my wifi network through the setup wizard. I'm not sure what has happened but it somehow lost the connection and is unable to find wifi networks. When using the setup wizard it searches and doesnt find anything (before it found my network as well as sorrounding networks).
I tried connecting it through a USB and configuring it that way but even then I get an error saying its unable to connect.
I'm using a Mac if that helps.

Hello @Pleaseworkty , and welcome to the HP Forums, I hope you enjoy your experience!
I see you're running into connectivity issues. I'd like to help!
What version of Mac are you using?
- Mac OS X: How Do I Find Which Mac OS X Version Is on My Computer?
I'd recommend performing a power reset on the printer. Disconnect the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug the printer back in. Ensure you plug the printer directly to a wall outlet. Make sure to bypass any sort of surge protector or power bar.
I'd also suggest the following document;

JournE Air 801 Not Finding Wireless Networks

My Air 801 was able to see my wireless networks when I first switched it on. I was having difficulty in getting WPA2 security to work so I reset the 801 to factory defaults using the reset hardware button on the device.
Now I am unable to find any wireless networks.
Any ideas how I can get my 801 to find wireless networks again?
Thanks for your help/advice.

Hi
Are you sure the Wifi is enabled in the settings of Air 801?
Usually the WLan icon should be visible in the left upper corner if the WLan has been enabled.
I downloaded the user manual for Air 801 (Toshiba European page -> Support and download -> user manual). On the page 42 you can find all the details about networking.
You can use the Wifi protected setup. This is the easiest way to connect to the network.
- Select Wifi protected setup and press OK
- press the wps button on your wlan router and then press ok to continue
- press exit to return to the previous page.
Then use the Wifi wizard to detect and to connect to WLan router in your area.
- select wifi wizard
- press up and down to select your preferred router
- press OK to confirm your selection
- enter the password for e secured router
You can also use the advanced configuration
For this check the user manual!

Finding wireless networks abroad

i am in sweden right now, and for the second time, my macbook pro (brand new) is unable to find the network that i am sitting right next to (and currently connected to by wire). the wireless router (which does work with a pc right now) is a dlink DI 624. i have connected without problem to a dlink here in sweden that has already had US-based apple computers on it, as well as to a hotel network here in sweden. this is the second time that i could not connect to a home network. i called applecare in sweden, and the only suggestion was to try entering the network information manually (including preceding the password with a $ and/or "). it did not work.
the information in the dlink manual only relates to setting up a wired connection (no problem, that works). i can't find any information on the dlink site.
any suggestions, it seems strange that airport cannot find find certain routers - btw, both routers to which i tried to connect required WEP passwords. (i have successfully connected to a router with password in the US).
thanks!

Having similar problems with my ageing G5and 10.5.8.
Sometimes get a 3 band wireless /fast connection to my network but at other times when waking from sleep get nothing. I have to reboot my airport extreme base station and the Netgear router and then the G5 can see the network again.
Recently had an issue with the G5 not recognizing the wireless password (WPA 2 personal) without logical reason.
I did a Keychain First Aid verify/repair.
Now back on a 3 band wireless and for now all seems fine.

Establish a wireless network between Photosmart C4385 and a Mac

I have a Photosmart C4385 All-in-One that I'm trying to use wirelessly. I have a MacBook Pro running OS X 10.7.2. I have a ubee wireless router.
I keep finding information saying that I need to run the "wireless network setup wizard" but I can't find it. I tried to use the different diagnostic utilites that HP suggested but they were only for PC, but the printer came with a Mac that I bought a couple of years ago. I have a new computer now and I'm just trying to get it setup to print wirelessly.

Hello,
Thanks for the post. On this one, I would recommend the following steps pasted in the links below. Good Luck!

Takes a long time to find wireless network

So for the past few months my (Santa Rosa) MBP will take an extremely long time to find a wireless network. This happens both at home and other places where I have connected in the past and am wanting to use a remembered network. It can take as long as two and a half minutes to connect. If I click on the airport icon in the menu bar, then it says it's scanning for networks during this time.
Usually if I create a new location then the problem will go away but then seems to come back. The problem also persists if I use a different user.
I've repaired permissions, done a disk repair and even used Diskwarrior. I miss instantly finding wireless networks. It's a small inconvenience, granted but was hoping to get this fixed once and for all.
Anyone have any suggestions of things to try? Thanks all.

Sometimes cannot find wireless networks??

i've looked around on a couple messege boards, but they didn't seem to be exactly the same problem i was having.
essentially, after waking up from sleep or hibernate, i sometimes cannot find wireless networks. the wireless switch will be on, Fn + F5 says my wireless is on, yet nothing can be found. strangely, when i try to turn off wireless, whether it's through Fn +F5, or the hardware switch, the light below the monitor remains ON. basically, i can't even turn it off. when i do click the button to try and turn off wireless, it gives me the busy cursor and eventually the whole menu disappears.
the way to fix this is by restarting.
just today, however, i suffered this same problem, even though i wasn't coming back from sleep or hibernate - it just lost connection randomly and then couldn't find any networks. attempts to turn off wireless failed.
is there a solution? is this actually the same problem that was remedied by changing a power setting?
thanks in advance.

Yeah I'm having this problem too, with my antique T41 running XP. It used to be rock solid it seemed to change when I installed XP SP3.
I have tried reinstalling the Intel drivers but that hasn't helped. It seems when it restarts after hibernate (and occasionally at other times, as with the previous poster) it somehow doesn't lock on to the signal or it gets confused in the protocol or something. It doesn't always happen though - about one in three. Rebooting cures it...until the next time....
any assistance / ideas most welcome, thanks.
PS I'm using Windows Zero Configuration not Access Connections. That was a change some years ago that made it work better so I'm inclined to stick with that unless someone can tell me why not....

HT1695 Ipad will not find wireless networks that it used yesterday, but MacBook Pro still finds and uses these networks.

Our ipad will not find wireless networks that it used yesterday. Our Mac Book Pro finds them and uses them.
we have reset the cable modem and wireless router, turned off the ipad and turned it back on. Turned wireless off and back on.
but it just spins trying to find networks but finds none.
What do do next?

Settings for wireless network connections are actually stored in two separate places on your Mac, so in addition to the correct advice offered by Jolly Giant, you will also need to delete old network listings in KeyChain Access.
Macintosh HD > Applications > Utilities > KeyChain Access
Locate the name of the wireless network that you want to delete and click it to highlight it
Click Delete on your keyboard
It would be a good idea to go ahead and also delete the current connection as well in case it has become corrupted. This will clear out the old settings and when you next connect to the network and enter the password, the new settings will be preserved.

AC 6.01 Message: Find wireless Network is disabled. Contact your network administrator

hi, i cant manage wireless networks with AC 6.01. Profile "Create" is greyed out and I am not able to create new profiles, can't find new wireless network etc. Few weeks ago, everything was working fine. When I try Fn+F5 and click "Find Wireless Netowork" I got message "Find wireless Network is disabled. Contact your network administrator". I am administrator on computer.
What i found interesting is that if i stop the service "AcPrfMgrSvc" from services.msc, i can find networks but then i cant use AC profiles i.e. cant create profiles and cant connect to any saved profile. This problem gave me real headache. This might be a problem due to any windows update.
I m using Windows 7 on Thinkpad E520. Please helppppp....

I don't think this is a Windows update problem. I encountered this same problem
immediately after I allowed Lenovo to update my laptop a month or so ago. (I have
always refused to allow Lenovo to update my system since I didn't trust them -
apparently with good reason - but I finally said OK. (My Windows 7 OS has not been
updated since Nov. 2012.) Lenovo has been no help in fixing the problem they
created (which has put Lenovo at the bottom of my list for future systems - see below.)
I have not tried disabling "AcPrfMgrSvc", I am only commenting on not being able
to Find Wireless Networks. I have read posts/comments in various places saying
to revert to a previous "version" of something (I don't remember what - AC?), but
have found nothing that explicitly states how to do that - as if it should be obvious.
Not helpful either. Documenting that would be the least Lenovo itself could do. (I
did try reverting to a full system backup I had made the day before, but I found I could
not do that without having a system disk that Lenovo said would cost $50 - which also
means NONE of the backups I have done over the last year and a half have any
value?)
So I have pretty much stopped using my two recent Lenovo systems and gone back
to my 9-year old Linux system.
