MacBook Pro Loses Wireless Printer Connection

I have installed my new HP wireless printer twice now. Each time it prints successfully, but after a few hours it loses the connection to the printer. My PC always works fine with the printer. I did discover that if I turn the printer off and then back on, the Mac will find it again. But of course that is a pain. Can anyone tell me why the Mac is losing connection and if there is a way to fix it? Thanks.

Printing from MacBook Pro to a Printer Connected to the USB Port on A MacG5

November 17, 2009
Apple Tells Me: It is completely valid to connect the HP 4360 printer (not wireless) to the USB Port of my MacG5 and print pages from my MacBook Pro if I select Print Share in the Apple Preferences of my MacG5. The MacBook Pro and MacG5 are connected through a Router and a wired Local Area Network through a Router.
HP Tells Me: Since the D4360 is not a wireless printer and since it is not supported to print from a MacBook Pro on the same wired local area network also connected to a MacG5 computer. In particular, they said that use of the Print Share option on the MacG5 to print from the MacBook Pro will cause damage to the HP D4360 printer or print driver and when this occurs it will invalidate the warranty on the HPD4360.
Questions:
1. Is there any validity to the HP answer on this subject??
My analysis to date says that the Apple statement is 100% true, with the exception that if the driver is damaged it can be restored without any damage to the printer.
2. Is there any documentation of the HP concern?

Is there any validity to the HP answer on this subject?
No. It's very difficult for any software to damage a hardware component, and on the rare case the driver becomes damaged, which is also highly unlikely, it won't affect the printer's warranty.

Macbook and macbook pro lose wifi internet connection. Why?

Have moved house, got a new internet connection everything has been ok for 2 weeks. Suddenly both my macbook and my son's macbook pro won't stay on the internet. They lose connection every 3/4 minutes.
We turn the airport off, close safari and then turn ariport in again. You can reconnect again but only for a short while.
We have other devices that connect to internet - internet radio etc. These don't drop connection so I don't think it's the internet/modem playing up. Even when these devices are turned off the internet connection fails on the macs.
I can also connect successfully to the internet using the ethernet cable.
What has happened?
Have we got malware?
What can I do?

You haven't brought any new technology which will effect your wifi signal? Like TV or Audio?
Have you tried to change the channel?
The problem really has to be related to the actual wifi router as both MacBooks have become effected.
If it was just the one MacBook, then there could be a possibility of some hardware having problems in the MacBook.
Are you getting a strong signal but no Internet?
If you have a house phone connected to the same socket as the router, the filter could need replacement.
Most DSL lines have filters that often need replacement after a period of time.

It's all about setting up what ever version of windows you have running on your pc to share the printer. If you still get stuck post in a windows forum for help.

My Macbook Pro doesnt seem to connect to my Belkin wireless router. It is connected but the internet would not work. any suggestions?

hey guys. I am having trouble with my internet. My MacBook Pro seems to be connected with Belkin wireless router, but the internet would not work. We recently changed the router so its pretty new, and it used to work on my HP laptop. Although there were some problems, it still worked. But now, the internet works and stops suddenly, and then works again.
I would love to hear some suggestions to get rid of this.
Thanks
Kiran

If you have not already done so, read the troubleshooting section in Belkin's user manual, contact their customer tech support by phone or go to its website. Please detail all you have done to resolve your issue. Need this information so that the users can avoid the "been there, done that" scenario type responses. This is to avoid repeating the troubleshooting you may have already tried. Thank you.

HT1349 My macbook pro will not print to wireless printer-it just printed fine the other day. Even reloaded the printer driver, etc, message is "there is a communication error" -in the printer queue it says it is printing then error message pops up

Macbook Pro unable to print to wireless printer-other PC prints fine and mac just printed a couple days ago just fine. Tried reboot of router-no change, tried reinstall printer driver, etc, no change. what do I do now?

As you can see here, that particular Canon printer is not supported by AirPrint:

I have an epson xp600 and a mac book pro. Wireless printing is OK if I'm lucky for one time only then a 'failed to connect' message so I have to delete and re add the printer to get it working again (but just once!) then the same occurs. Why?

I am not certain this will fix your problem but I suggest you assign the printer a static IP address.
Using the printer's front panel, select Menu > Network > WLAN > TCP/IP > Boot method, and change it to "static". Provide a static IP address that is on your LAN's subnet.
For example, if you are using an AirPort Extreme, you might give it an IP address of 10.0.1.100. If you are using a Netgear or Linksys router that defaults to issuing 192.168.x.x addresses, you might give it an address of 192.168.1.100. That way, the printer will always "reside at the same address" on your network. If your router has the ability, you should reserve that address so that the router does not attempt to assign it to another DHCP device.
Then, go to System Preferences > Print & Scan, and delete your existing printer with the "–" (minus) button. Add it again, using the "+" (plus) button. In the window that appears, select the IP pane, and from the Protocol menu select "Line Printer Daemon (LPD)". In the Address field type the IP address you gave your printer.
If all goes well the "Pring Using" field will detect the printer at that address and automatically select the appropriate driver. You will see something similar to the following screenshot ("name" can be whatever you decide, and "location" is optional):
Click Add, then you can close System Preferences.
There are other possible reasons your printer is "not responding" which could include wireless interference from competing wireless networks, but try this "static IP" method first. It should mitigate the problem.

MacBook Pro drops Wi-Fi connection after upgrading to 10.6.5. Fixed!

MacBook Pro drops Wi-Fi connection after upgrading to 10.6.5. Airport says no IP is detected then suddenly reconnects?
This has been a problem I’ve been troubleshooting for the last month. I’m new to the Mac family and have loved my experience up until this point. I was under the impression that mac’s are supposed to be so user friendly that even your grandmother could use one with out having any technical knowledge. I mean I shouldn’t have to be deleting drivers or reformat my mac because of an OS update glitch? (That’s what the guy at the Genius Bar told me to do.) What I refused to succumb to was that I’m really good with computers. I get at least a phone call every other week from someone asking me for tech support. So I’d like to think that nothing I’ve done to the system would have caused this anomaly.
After numerous attempts of troubleshooting and researching forms I believe I’ve discovered a solutions that seems to be working for me.
Here are the steps I took to create a consistent connection to my Wi-Fi. I believe it was a combination of all these steps to create success.
1.) Changed my router to use G Wireless Only. (I’m assuming this removed any unnecessary frequencies to allow G to broadcast stronger?)
2.) Did a scan on the other networks in my area to find out what channel everyone else was broadcasting on. Copy and past the text below into a terminal window.
sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resourc es/airport /usr/sbin/airport
This will allow you to simply type “airport” in the terminal window to execute the command.
Type airport –s
This will display all the networks in your area and what channel they are broadcasting on.
3.) Changed my router to use a channel that no one in my area was using. (This helped to make my network stronger and free of interference.)
The last steps will help your home network improve but these next steps I believe helped fix any install errors caused maybe by the 10.6.5 update on my mac.
4.) Boot your Mac into safe mode by holding down the shift key while booting.
5.) Open System Preferences and Click on Network.
6.) Click the drop down menu from Locations at the top of the screen. Click edit locations..
7.) Create a new location by clicking the + and give it a new name.
8.) Delete the old location by clicking on the old locations name and click the – to remove.
9.) Reboot
10.) Open System Preference and click on Network.
11.) Click on the settings sprocket next to the + and – and click on Set Service Order…
12.) Drag Airport to the top of the list of devices then click Ok.
Now this last step is what seemed to eliminate the issue. I hardcoded my IP address to my network. This way my computer will always use the same IP and not have to search.
13.) Click on Advanced under Network.
14.) Click on TCP/IP. Click on the drop down for Configure IPv4 and change it to Manually.
15.) Fill out the fields with your IPv4 Address: 192.168.1.1xx (x=whatever number) Subnet Mask: 255.255.255.0 Router: 192.168.1.1 (All of these settings are pretty standard for most home networks.)
16.) Click on the drop down for Configure IPv6 and change it to Off.
17.) Next click on the DNS tab at the top.
18.) Click the + to add a DNS Record.
To find your DNS Server open a Terminal window by launching Applications --> Utilities --> Terminal
Then Type cat /etc/resolv.conf
(There is a space between cat and /. Without it you’ll get no such file or directory.)
This should return two addresses. Your ISP’s DNS Servers.
19.) Add both records to the DNS and click Ok.
20.) Click Ok then under Network Click Ok.
21.) Reboot router then Mac
22.) Fixed my connection issue
The symptoms I experienced eluded me to believe that something with the DHCP is going into an idle then disconnecting. Before when DHCP was set to automatically assign the network signal would time out then searchers for a new IP resulting in Airport displaying No IP is detected. By setting my IP to a fixed address I still notice a slight drop in bandwidth at moments but because of the assigned IP I never loose connection. I can now stream video, play games, chat all without getting disconnected.
I believe this fix will work for my home network but I also noticed this issue at work so for each location that I connect for the time being I’ll create each there own location and hardcode the IP address to that network. I’ve been reading that 10.6.6 is coming soon so maybe this will be resolved for good in the next update.
Let me know if this helps or if you have any questions.
Best of luck.

I have been having the same issue for the last two weeks. No real indication as to why it ever began other than I had turned off my router and Airport Extreme Base Station off for a weekend while I was away from my place.
iPad, iPhone, iPod Touch, all have no issues at all with my Airport Extreme Base Station. Can stay connected throughout my living room, bathroom, bedroom, no issues whatsoever.
My 5 month old MacBook Pro 2.66 GHz Core i7 Airport is sometimes perfect, able to connect, DHCP, and browse without issue. Then, for no reason, I won't be able to join my wireless network, or when I can join, I can't pick up an IP address. And then it will connect, pick up and IP, and then it won't browse. No real rhyme or reason to when this will happen, or when it works.
I thought that it was an issue with my MacBook Pro, but then my sister visited with her brand new MacBook Pro 2.26 Intel Core 2 Duo, and while a month ago she was able to connect, DHCP, and browse without issue, this weekend she had all of the same issues I was having.
My XBOX 360 and MacBook Pro have absolutely no issues with the wired connection. Only my WAN seems to have this issue.
Did you ever find anything more to this?

MacBook Pro can't actually connect to Wi-Fi with Self-Assigned IP

Hi there
I have a 15 inch MacBook Pro and it can connect to Wi-Fi but have no actual data coming in. And it says self-assigned IP.
This only happens to my home Wi-Fi, however, I can connect and use Wi-fi at school or anywhere else perfectly. In the mean time, my Android phone and my flatmates' Windows have no problem using the Wi-Fi. The problem has been going on and off for a month, sometimes it works again and sometimes it goes wrong like this again.
During this time I mostly use my other MacBook Pro 13 inch Retina. Until today, this problem happens on my 13 Retina mac for the first time, and the 15 Pro again as well. A few days ago, my 15 Pro started working again, and today they just gone wrong together at the same time.
I just found out that my 15 pro can still work if connected to ethernet, but I can't just work in the living room, where the router is. And as you know Retina doesn't support Ethernet.
I've check on the Internet and found many people have the same problem as I do. I also tried lots of ways to fix it with the information I found online. And nothing works. I even suspect that it's actually my flatmate blocks me out with some setting on the router (Is it possible?)
Anyways, can someone please help me fix it thoroughly... Please and thanks.

Each country regulates wireless networking differently. Wi-Fi devices are restricted to certain frequencies and power levels. The client devices try to find out where they are and configure themselves accordingly. Since a wireless access point (WAP) usually does not move across national boundaries, the Wi-Fi regulatory domain (country code) is set by querying the first one to respond when the client initializes itself. You don't have any direct control over it on the client. If your device is picking up the wrong country code, and is therefore locked out of using some Wi-Fi channels or operating at full power, the only lasting solution is to fix or remove the misconfigured WAP.
To find out which WAP's are broadcasting a wrong country code, do as follows.
Triple-click anywhere in the line below on this page to select it:
/S*/*/P*/*/*/*/*/airport -s | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V.
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign ($) to appear.
A TextEdit window will open with the output of the command. The first line should look like this:
SSID BSSID RSSI CHANNEL HT CC SECURITY (auth/unicast/group)
Each line below that one represents a WAP within range. Compare the two-letter code in the column headed "CC" with the ISO code for your country. The code "X0" means that the country couldn't be determined. If a WAP with a wrong code is not under your control, try restarting the computer as close as possible to your own router.

As I mentioned above, I am not very tech savvy so I have no idea why a wireless protocol would be showing up there, I'm just listing everything I see in hopes that someone might know something I can try. This is why I am asking for help here - I'm not sure what has happened that has made me unable to connect, especially since it seemingly occured while nobody was using the computer.
I guess I should clarify that I'm not a total hillbilly- normally my firewall is set to 'on', but I set it to 'off' to try and troubleshoot the issues here as I was told that sometimes it can interfere with the computer's ability to connect to the internet. If this is not the case and firewall does not affect anything, I will turn it back on while I try to fix this.
I have tried the method you mentioned above a few times - I actually contacted my ISP earlier this week and they recommended resetting the router like that. They didn't mention any known network issues.

Macbook Pro suddenly will not connect to the internet via ethernet cable.

I know this is a long shot... but I figured I would give it a try.
My macbook pro suddenly does not connect to the internet via ethernet cable. Please bear with me, as I am not very tech-savvy - I will try my best to describe the symptoms!
I connect to the internet via ethernet (we don't have wifi). It was working before I went to work, and when I came home I suddenly couldn't get anything to work (I know everyone says this, but I truly didn't mess with anything). Internet browsers just think for awhile and then turn up the 'You are not connected to the internet' error.
I went into my network preferences and curiously, the 'Ethernet' shows a green dot and says 'connected'. However it says 'Authentication server is not responding' underneath the last part that says '802.1X: WPA: eduroam' (I think that is my user profile).
When I go into my 'security' settings I can see that my firewall is off, so that shouldn't be causing any problems.
I've tried restarting the router and computer itself many times. Diagnostics just gets to a certain point and reports back 'Network Diagnostics cannot fix the current networking problems.' I've also tried switching to a different ethernet cable, and I tried both cables out on a PC laptop and it connected without issue. Additionally, I brought my macbook along to a friend's house and it connected to his wifi just fine, so the problem appears to just be with ethernet connections.
I know it's hard to troubleshoot this kind of thing without being there and having a look at the computer yourself, but any tips wouild be greatly appreciated.

Officejet Pro 8500a wireless printer hangs up when printing document.

I have an officejet pro 8500a wireless printer and it has been working flawlessly. Now all of a sudden it hangs up when sending a document to it. It will say "now printing", with the red "x" and just sits there looking at me. I have discovered that I can open the printer lid and close it and it will then print??????
Also when I click on "apps"on the printer menu screen, it tells me, "unable to connect to the server".
Anybody experience this problem??

I too have this issue with my HP8500a Plus.
I have managed to narrow down the issue to one of the cartridges. Whenever this cartridge is inside the printer, the issue will happen. If it's not, then the issue disappears!
I have tested this discovery on TWO different hp8500a printers, and they both react to this "special" cartridge the same way: its presence inside the cartridge tray triggers the issue.
There is only one thing that makes this cartridge any different form the other ones: even though it IS a genuine HP cartridge, it has been refilled and the max allowed page count has been hit. The issue started happening only after the max allowed page count has been hit.
