MacBook Pro OSX 10.8.4 Internet connection difficulties

Hi, hoping someone can help here. I'm currently using my home network on my iPad, my wife using her older MacBook with our iMac on and both iPhones are surfing the Internet fine. HOWEVER my new MacBook Pro (version 10.8.4) recognises our home network but doesn't always want to 'activate' if that makes sense.
I have seen other users with this issue and have tried getting rid of keychain data and all networks and starting again (with putting a .old for a system preference folder as recommended by one user) however still no joy. Any opinions welcome!
Thanks

If it is a wifi network, here are some troubleshooting suggestions.

New Macbook Pro (Late 2013) Continuously Loses Internet Connection

My new macbook pro is constantly losing internet connection. I have already:
1) Replaced my home modem and router (just in case)
2) Troubleshot the home internet with ISP - they say it is not on their end.
3) Run through a million resets of the home internet system
4) Checked to see if other computers are losing internet (No, it seems to be only this computer affected)
5) Done diagnostics with Apple on two separate occasions (This did no good)
Now the interesting thing here is that I thought at first it might be a hardware issue with the internal mac modem on the computer. That is also what apple was suspecting... HOWEVER, whenever this happens, if I reset the PRAM everything is fine again for 3-7 days. You would think this would not be the case with a hardware issue, right? (It is important to note here that apple said PRAM reset wouldn't change anything - but it clearly does)
I have seen posts saying the antenna could be bad when others have had this problem, but again, if PRAM reset works, you wouldn't think it was the antenna, right?
This is driving me crazy and it is a new machine. I am also in a situation where I don't want to be without it for days to have it repaired so any suggestions on how to fix this problem would be helpful.
I have considered that it might be a profile issue (I did migrate another profile to this machine), but again that seems unlikely.
Any help or suggestions would be appreciated! Thanks much!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

MacBook Pro and Wi-Fi Slow Internet Connection

Hi There,
I just got Macbook Pro. I am new Mac user and ran into strange problem. when I connect to internet through Wi-Fi the speed is really awful in comparison with my other windows based laptop at the same time.
How could I solve this problem? I mean, is there any specific setting I am supposed to do to overcome my slow internet speed?
Thank you

Your ISP's DNS servers are not communicating with your Mac properly. This is a common problem. Follow the instructions and setup your own DNS servers from OpenDNS: http://www.opendns.com/

Hi, I have a MacBook Pro and a PC both connected to a TC who in turn is connected to a cable modem. I have no wifi accessfrom my MacBook pro (self assigned IP - no internet connection msg) while I do on PC through ethernet? can anyone help?

I was working yesterday afternoon when the wifi suddenly went cold. Initially on the MacBookPro and on the ethernet connected PC. I reinitialized modem and TC through the mac and then the ethernet on the PC worked again and has since.
I've reinitialized both the modem and TC many times, as well as checked the cables. Moreover, I've tried to renew the DHCP lease, provide the DNS servers manually, erased all networks in Network preferences and in KeyChain etc. but nothing seems to work.
One strange thing also happened. I had two networks created, one for me and one I created for guests. The latter one just vanished, dissapeared without a trace.
I've tried from the café down the street and the Wifi worked perfectly well though a little slow, but that could be their connection not the Airport. Therefore, my I deduct that there is either something wrong in the TC or something went wrong in the network settings in the Mac. But that doesn't help to move forward and fix the darn thing.
The only thing I haven't done is completely reset the TC, but after reading a couple of help threads on different forums I'm confused as to how to proceed to get it back to worrk? Has anyone had the same or similar issue and found a solution?
Thanks

Eh la Pastenague! Je savais que tu était léthale pour l'homme mais ce sont pluôt les machines à pommes qui devraient te craindre. Merci! Solved.
For future reference.
My TC is a 3rd gen.
I actually had to reset to standard defaults not only once but twice. The first time I simply returned to my old profile but that only led to the same message error on the network settings (i.e. IP by default, cannot connect to the internet). Therefore the second time around I kept my profile as backup and re-created a new one plus a guest one.
The airport utility then signaled to issues remaining:
1) Internet access was cut - this I solved by simply reseting the cable modem
2) There were no DNS Servers - I simply copied the ones I had from the previous setup and it worked
I did have AppleCare....
I'm online again and I hope for good.
Thanks a lot
PS. a small tip - I made captures of all my settings in Network settings, Airport Utility and Network utility using Grab in case of ... if anything it is just handy to get back settings that your are missing when setting up a new configuration

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.

MacBook Pro OSX 10.6 drops Wi-Fi connection when idle/asleep.

My MacBook Pro OSX 10.6 has begun to lose Wi-Fi connection when idle. I can't re-connect unless I shut down computer and re-start. Worse, the system appears to lock up--I can't force quit, must press the power button to shut down. This problem occurs wherever I am using my laptop, not just with one particular Wi-Fi network.

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?

My 2011 Macbook Pro OSX 10.8.4 latest update won't connect to secured Wi-fi

2011 Macbook Pro
OSX 10.8.4 latest updates
Suddenly stopped connecting to any wireless network which is secured, WEP/WPA/WPA2/personal/enterprise all do NOT work.
Connects to unsecured networks just fine.
For example, our wireless password is:
123456890!
I tried with WPA2, no luck.
Tried with WPA2 and pw 1234567890, no luck.
Tried with WPA and pw 1234567890!, no luck.
Tried with WPA and pw 1234567890, no luck.
Tried WEP with 1234567890, no luck.
Tried with NO SECURITY on this wi-fi network, connected right away.
-I did reset PRAM, no luck.
-I deleted from Keychain, no luck.
-I added as prefered network and removed, no luck.
-I added new network location, no luck.
-I removed the Wi-fi network adapter, rebooted, activated, no luck.
-In the mac console logs, all I see are "wlEvent: en1 en1 link DOWN" when I try to connect to my secured wireless network (home or my office or even at a neighbors).
-Wireless diagnostics tell me nothing
-Console logs do not tell me anything
-Warranty is expired and no AppleCare
Seems like a bug to me, even though I have tried with a Netgear, Cisco/Linksys, D-Link router and even tried tethering to a Samsung Galaxy Note 2 and iPhone 5, all same problem, says "Connection failed."
APPLE FRIENDS HELP ME PLEASE!

For example, our wireless password is: 123456890!
Well a password that weak will get cracked in about 6 hours on just about any PC in the area.
Now: LKUY*&T&67NH(*JKÎM<PijriuÎÓyhm8t, that's a real good network password, even a huge botnet would have trouble cracking that. I know because my router was PING flooded by the Flashback botnet and survived.
After OS X is reinstalled over itself to fix it, you might have to do more as it could be a "in user account" issue with a corrupted preference file, bad users permissions or another cause that's not OS X

My macbook pro (lion 10.7.2) stopped connecting to wireless internet even though network indicates it is connected - full bars.

My macbook pro (10.7.2) just stopped connecting to the internet. 2 other macs in the house are working fine. All 3 are in the same room as the airport. The macbook network icon indicates it is connected with full bars. We have turned the computer off and on, but no effect. Any ideas?

Have you tried turning Airport off and then on again? My own q about this is somewhere in the answered q's--what worked was either the Airport on-off or something my phone company did while I was fiddling with Airport. Good luck!

How can I play music on my macbook pro (OSX Lion) through a Pioneer receiver. I've connected them with a mini display port to HDMI cable with audio support bought at the Apple Store, but there's no sound coming through. thanks

How can I play music on my macbook pro (OSX Lion) through a Pioneer receiver? I've connected them with a mini display port to HDMI cable with audio support bought at the Apple Store, but there's no sound coming through. There are 4 HDMI-in ports on the receiver - BD, DVD, DVR/BDR and audio. In my system preferences for sound, the receiver doesn't show up as an output option. Can anyone please advise. (ps, this is my first time posting a question, so I hope I can find your answers!) thanks, JP downunder

For sound, try the audio output port and connecting to the RCA audio input ports on your Pioneer receiver. Use something like this:

My HP ENVY 100 D410a is connection issues between MacBook Pro OSX 10.6

Both my Macbook Pro OSX 10.6 and my HP Envy 100 D410a is connected to my wireless nextwork. Everything was working fine until recently, my macbook does not connect, - keeps saying the printer is offline when it clearly is on and connected. I have tried to reinstall all printer software and drivers from CD and the HP site, it fails when the laptop tries to connect to the printer.
Any advice / help would be appreciated.
Thanks.

Sure.. a reset will surely do it.. a removal of the offending name will also do it.
Can I delete all networks by resetting the router back to factory settings?
Sure can.
I also have this UPDATE "A newer version 5.6.1 of airport utility is available" it KEEPS opening when I open my Airport Utility APP, but when I click on it to UPDATE nothing happens, ever. Im already running 7.6.3
Bit of confusion here.
Latest version of the airport utility for snow leopard is indeed 5.6.1
Open the airport utility, about .. and check what version you are running.
The very latest airport utility is 6.3 and only can be installed on Lion or Mountain Lion computers.
The firmware latest version is 7.6.3
which makes it all a bit confusing.

I'm unable to do a clean install of Firefox 6 on Macbook Pro OSX 10.6.8.

I'm unable to do a clean install of Firefox 6 on Macbook Pro OSX 10.6.8. After trashing the firefox.app from the Applications folder and trashing a related file in the Library folder and then reinstalling, all of my previously opened windows and tabs reappear.

MacBook Pro OSX 10.9.4 - can't open document in pages - message says need updated version and there aren't any

MacBook Pro - OSX 10.9.4 - trying to open document in pages. Message says can't open with this version - go to app store for update, but there aren't any updates.

Hope apple can fix this soon if new patch 10.9.4 cause this.
Apple cannot fix problems they did not create. Eset and Avast are capable of doing nothing beneficial and can only cause problems. Uninstall it and determine if the problems subside.
Use Avast's uninstaller, which will remove it completely. Eset requires using the uninstaller included with its downloaded installation program (see screenshot):
Eset will also require manual techniques to uninstall components its uninstaller leaves behind, a common characteristic of poorly written software.
I am now can access an internet, with zero security.
It's a common misconception that you have "zero security" without junk such as Eset or Avast. OS X already includes robust protections against viruses and malware. Use your Mac the way it was intended to be used - without burdening it with useless garbage.
