Safari not connecting to internet after software update

I have just completed a software update and now safari will not connect to our wireless internet... airport says it has full bandwidth and other macs connected to the wireless connection are working without any fault.... has anyone got any ideas????
Thanks!!

Hello Sarah:
As you probably have already guessed, quite a number of things might have happened.
My network is Ethernet, so I am not much help with wireless networks. However, I think I would (if I were you), run an archive and install:
http://docs.info.apple.com/article.html?artnum=107120
An archive and install will place a fresh copy of OS X on your system while, at the same time, preserve your files, programs, and settings. It is always a good idea, however, to have a good backup strategy before any software changes. You should then run software update to bring your system to a current level (in your case, OS X 10.4.11 is current, I think).
The A&I should eliminate any system software issues.

HT4623 My iPad is not connecting to internet after software update what can i do

Hi everyone I just update the software 7.0.4 on my iPad 2 and after doing that cannot connect to internet, can somebody tell me
what to do to correct this issue? Please

You can try resetting your iPad by simultaneously pressing and holding the Home and Sleep/Wake buttons until you see the Apple Logo. This can take up to 15 seconds so be patient and don't release the buttons until the logo appears.
Try again to see if the problem persists.
If yes you can try resetting your Network Settings. Settings > General > Reset > Reset Network Settings. Note that you will have to re-enter all of your WiFI passwords.

Cannot connect to internet after software update

I have an old powerbook G4 running Mac OS X 10.3.9 (this is one of 3 macs) I also have an airport Extreme and an airport Express to make a network in my home. Frequently, after a software update to the old computer, it has trouble getting back on to the internet. Usually, adjusting access to the Keychain fixes this.
Now, after a software update last week--I cannot get on the internet with this computer at all. The computer is connected to the network, the password is in the keychain, the signal is strong (all of the other computers can get on to the network)--but whenever I try to get on, I get 'cannot connect to the server'.
(btw, Last evening, the issue resolved itself for about 3 hours--I don't know why--but today it is out again.) Can anyone help?

Hi, Rathh. Always use Disk Utility to repair permissions immediately after installing any software update that uses Apple's Installer application, or that is installed by the Software Update function accessed through the Apple Menu.

Can't connect to internet after software update to iBook G4

I recently installed updates to itunes, quicktime, and the the latest security update for os x 10.3.9 on my iBook G4. Now I can't connect to the internet via my airport express. This happened the last time I updated the software, but I can't remember what I did to fix it. Can anyone help?

I am experiencing the exact same problem with my sister's laptop. iBook G4 10.3.9 I just installed Security update 2007-008 and quicktime update. After the reboot her airport connected to the house router, but will not acquire an IP address. The other computers in the house have remained connected to the router without change. I have a another iBook G4 running on 10.4.11 with the same network settings and I have no trouble whatsoever. I re-enetered the WAP password, reorganized the network connection priorities and repaired permissions, but cannot get the computer to acquire an IP address.
Any ideas??

Can't connect to internet after software update

I just downloaded todays (3-1-2006) security update from apple. Once I rebooted my ibook I wasn't able to connect to the internet anymore. Any ideas why?
My internet connect is still good as I am typing this on my wifes ibook just fine.
thanks

Mike,
Check my post on the "Customization" thread in reply to "Onthegomike." I experienced a similar problem with my desktop and was able to resolve it. I have not yet downloaded the Security Update to my laptop; however, I'm sure I'll have to go through hoops again once I do that. Repairing permissions before and after sometimes helps, however, I often have to go through the disconnection of my airport express before I'm up and running on the iBook.

Can't connect to internet after software updates to ibook g4

You might have better luck posting in the OS X forum. This forum is for the iPhone.

IPhoto not connected to internet after latest update

I just updated my iPhoto last night according to notification. Then, everytime I change desktop, either to LR3 or CS5 and return, iPhoto is no longer connected to the internet therefore, I cannot upload to Facebook, Flicker or email from iPhoto.
I have to close iPhoto, restart iPhoto, then its OK. How silly. It was never that silly before.
What's happened? Who made what change to the good code? Is there a fix?

As a test launch iPhoto with the Option key held down and create a new, test library. Import some photos and test to see if the same problem persists. Does it? If it does then try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
User/Home/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iPhoto folder (Snow Leopard and Earlier).
or with Lion and Mt. Lion from the User/Library/Containers/com.apple.iPhoto/
Data/Library/Caches/com.apple.iPhoto folder
3 - launch iPhoto and try again.
NOTE 1: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto. You'll also have to reset the iPhoto's various preferences.
NOTE 2: In Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
Have you rebooted since this problem occurred?

HT5642 ipod won't connect to internet after software update

Help. I can't get my ipod to connect to my wifi since I downloaded the new update.

Does the iPod connect to other networks?
Does the iPod see the network?
Any error messages?
Do other devices now connect?
Did the iPod connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router
- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

IPad Air can not connect to internet after updating to iOS8.

Safari CAN NOT OPEN ANY PAGES because the iPad is not connected to internet. I updated to iOS8 last night and have been trying to reset my ipad as well. However, the problem is still there. It even says my Apple ID incorrect. GUYS! DO NOT UPDATE YOUR iPAD TO iOS8 UNTIL FURTHER NOTICE!!!!!!!! Luckily, I did not do anything with my phone. PHEW

Other threads I've read have had people note that the following solutions have worked for them:
If you have a 5 GHz wi-fi router, turn off 5 GHz support and let it fall back to 2.4 GHz.
Change wi-fi router to auto-select channels, or manually select a different channel than what it's on now.
Disable iCloud Drive.
I'm not saying that that any of these will work, but it's something to try (one at a time).

1st problem see http://kb.mozillazine.org/Firewalls

:not with the [x] in upper right corner which close window
:see http://kb.mozillazine.org/Firefox_hangs#Hang_at_exit
:if restarting use "Restartless Restart" extension as mentioned there.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) 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 (Auto or Channel 6 is best). 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.

I cannot connect to internet after I update system.

Hi,
I update my system a few day ago (use systemd to replace rc.d) and I cannot connect internet. I guess my router table is broken, but I cannot find any problem.
I use ping to try some IP. And I find I connect to local machine only.
Do I miss some configuration ?

Safari and iTunes not connecting to internet after 10.5.3 but firefox does

Hi,
My first post ever. I just updated to 10.5.3 from 10.5.2 After the update, I can not connect to the internet using Safari. I get an error message that I have no internet conection. I ran the network diagnostics and everything was reported as working correctly. I also ran a repair permissions from disc utilities. Still can not connect with Safari. I also noticed that itunes can not download any podcasts. My "software update" in system perferences can not connect either. Firefox has no problem going online.
Any suggesttions on how to proceed?
Thanks

Also worked on 10.4.11. I installed an Airport Express and updated all the software and firmware on my MacBook. After Safari, Itunes store, Google earth could not connect but Firefox was connecting fine. Followed your tip. Disableing the proxies on the Network config does the trick. Very simple but very helpful, thanks.
