Imac g5 won't connect to internet wirelessly or by ethernet

I have an early 2006 iMac g5. I haven't been able to connect wirelessly for several months now (all other computers will) and this past tuesday we had a power outage and now I cannot connect via ethernet either. My laptop will connect fine through the same ethernet cable but the g5 gets nothing.
Could this be the airport card?

Hello Jwine2011
It could possibly be the AirPort card giving you troubles. To troubleshoot the issue of not being able to connect to Wi-Fi or wired network connection, start with creating a new network location. Check out the first article to go over that. If you are still having issues, then check out the second article with troubleshooting issues connecting to Wi-Fi.
Using network locations in OS X v10.5 or earlier

My iMac g5 won't connect to a wireless network

I just got a new hard drive- and now I can't connect to our wireless network- all our other items are connecting so its not the router- thoughts?

Hi, this has worked for a few...
Though all of these steps may or may not be needed, I'm including them all.
Make a New Location, Using network locations in Mac OS X ...

10.7 & 10.8…
System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.
10.5.x/10.6.x/10.7.x instructions...
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
10.4 instructions...
Is that Interface dragged to the top of Network>Show:>Network Port Configurations.
If using Wifi/Airport...
Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.
For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...

(There may be better or faster DNS numbers in your area, but these should be a good test).

IMac G5 won't connect to internet via Ethernet

So i have an iMac G5 that isn't connecting to the internet via ethernet.
I have already taken a look through all the Network Preferences, tried going through the network port configurations and setting all of that up again, created a new location for it.
I tried turning off the modem, and letting it restart - restarted the iMac - tried to set up all of these settings again.
I also created a test user account to see if it would work there - still nothing.
I hooked my own 17" MacBook Pro to it and it works perfectly. I never had to go through any settings on mine - it just worked as soon as i plugged the Ethernet cable in.
So the modem itself works - because my computer works. What else could be the problem?
I went through the Network Diagnostics on hers - all green dots and it says that the internet connection is working perfectly. It gives me an IP address - but it still won't load a webpage, and it tells me there that i am not connected to the internet. I am all out of ideas.
If anyone can help me with this it would be greatly appreciated. Thank you so much!

What OS you using? 10.5?
My memory of 10.5 is fading so you may need to figure out the vague instructions.
To make this easier to type Macbook Pro = MBP
When testing disable wifi & use ethernet on both machines.
Are both set to use DHCP? Or are you using manual settings?
Compare the IP addresses of the MBP & the iMac when they both use ethernet.
Compare the subnet masks too just to be sure nothing is different.
Does the iMac do any local networking at all? (e.g. is iTunes or File sharing visible on it). see *
Does it see the MBP in the sharing sidebar or can it connect to anything on the local network?
Have you connected the MBP to the iMac using the exact same cable that the iMac connects to the router?
Does the MBP work if connected to the router using the iMacs ethernet cable?
* You will need to enable file sharing to see the shared Mac in the sidebar (or have mother service shared). Enable it in System Preferences > Sharing whilst you test.
If you are have local networking in a functional state it could be…
DNS - what is the iMac DNS set to on each Mac?
Are either of them showing a grey DNS entry in System Preferences > Network? That means the router is supplying that info.

Imac 500dv won't connect to internet

Hi, I'm trying to help some friends out, I gave them an imac 500DV (grape?) a year ago and they haven't been able to connect to the internet. They are disabled and unable to work so money is tight, for this reason they chose Talk Talk broadband which is free with their phone contract but is known in the UK to be far from the best and badly organised. Also neither of them has a good knowledge of computers and have wasted time with the Talk Talk helpline. It had connected fine when I had it, I did a clean install of 10.2 before I gave it to them too.
I am visiting them for a day after new year and I want to get it working for them or at least find out if the problem is with the computer or the broadband provider.
They are currently running 10.2, I plan to put 10.3 on there when I visit, I'm hoping his will help as I know originally there was a line problem and many computer setting were messed with before this fault was recognised. I'll then try what I know and phone the helpline myself to see what they recommend.
Basically I'm wondering if someone could give me a list of checks I can run through (on 10.3) to see where the problem is. I might change the PRAM battery too while I'm there as it's never been done and may well need replacing. How do I do this on the old imac?
Thanks in advance for any assistance,
James

Here's a link to info about how to get at the guts of an iMac. (Since you are in the UK, no need to "translate" terminology like 'cruciform screws'!) It covers battery replacement as well as a lot of other stuff.
http://www.sterpin.net/uk/imacslotinukp.htm
As for the broadband connection, my experience (in Canada) is that the OS installer looks after it. I have seldom had to fiddle with anything. After the OS installation, which is done with the computer connected to the internet, you are prompted for personal info, including how you connect to the internet. Once the info (ISP provided user id, password etc.) are entered the connection is done for you. If that does not work, there are steps you can try. The easiest and the best is the OS 10.3 included "assistant" that will, if necessary, trouble-shoot the connection process. It goes through the 'list of checks' that you need.
Good luck.

My iMac can't connect to internet wirelessly

I purchased a 27" iMac in 2013 version 10.8.5. For no apparent reason, my iMac won't connect to the wireless. According to my iMac I have full bars but when i open my browser and try to connect to any website, the page won't open. The browser continues to try to load page for some time and eventually displays "Safari can't open the page "http://<website address>/" because the server where this page is located isn't responding." I had, prior to this problem, and still have, after this problem, other devices connected to the same wireless router without problems. My current wireless router doesn't have a password, however, there are no neighbors close enough to connect to my wireless router. I've restarted my computer, shutdown my computer, restarted my wireless router, turned on/off Wifi to no avail.
Per System Preferences>Network>Wifi, i have a green light with status: Connected. My Airport Utility however switches back and forth between connected and not connected. But regardless of what my Airport Utility says, I can't access wireless. I'm looking at the IP address and my macbook pro is connected to the same IP address without any problems. Does someone know what's going on?
Please help!

Hello, littlemold
Thank you for visiting Apple Support Communities.
I see you have already processed most of the relevant troubleshooting steps for this issue. This could be related to your router assigning a self-assigned IP address. I would recommend going through the steps in the article below.

My iMac is not staying connected to my wireless internet. Any suggestions? My provider says it's a computer issue and not their problem.

My iMac is not staying connected to the wireless internet. My provider tells me it's a computer issue and not their problems. Any suggestions?

Please test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
Step 1
Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 2
Disconnect all USB 3 devices. If you don't know which are USB 3, disconnect all USB devices except keyboard and mouse.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.
Step 4
Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
Step 5
Reset the System Management Controller.
Step 6
Reset the PRAM.
Step 7
Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
Step 8
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

My iBook i just bought from USA won't connect to my wireless

My iBook i just bought from USA won't connect to my wireless that my iMac works on. Please help I'm seriously clueless and its driving me crazy!
I just says error when i type in the key and invalid password when I type in it in network assistant! ):): It comes up as WAP being the only option when I click the network name. but i don't actually know what WAP means....

Go to Hard Drive > Applications > Utilities > System Profiler to tell the MHz rating, how much RAM is installed, and what type of optical drive it has.
To run Repair Permissions, go to Utilities again, and click on Disk Utility. Choose the named hard drive ("Macintosh Hard Drive" unless it's been renamed), and click on "Repair Permissions."
What encryption are you running on your network? Do you have a router? If so, it needs to be set to a mode that will work with the 802.11b standard, since that is what the iBook's original AirPort Card uses.

Nokia N80 won't connect to internet via airport extreme

My Nokia N80 connects to the internet through a wireless network at work (not sure of the set up) but won't connect to my wireless network at home which is airport extreme with 128bit encryption. Any clues?
Thanks in advance

Probably a WEP key issue.
One of the problems with WEP is that the actual standard relies on a 10 character HEX key for 40bit WEP and a 26 character HEX key for 128bit WEP.
In order to make things easier for people, vendors use certain algorithms to convert simple alphanumeric passwords (or passphrases) into HEX keys, thus enabling people to use simple memorable WEP password rather than lengthy HEX keys.
The problem is that different vendors use different algorithms to generate the HEX key and therefore a ASCII password on an AEBS will be hashed differently on a Netgear client and vice versa.
One thing is a 13 character 128 bit WEP password will be hashed by all vendors in the same way (if you use 40bit WEP then a 5 character password is required).
Though sometimes not even that works and the HEX key must be used regardless.

Mac Mini won't connect to internet using Apple products (Safari, iTunes, AppStore). Date and time are frozen to the moment CPU is booted up. Firefox works. Cannot update.

For the past few days my Mac Mini has been having issues.
Safari won't connect to internet, but Firefox does.
Time and date are frozen. Only resets when copmuter is re-booted.
Unable to update via App Store and iTunes won't connect either.
Please advise.

Hi again,
Let me ask for some better help for you that is familiar with this problem (if in fact it is a similar problem with the IP address and your ISP.
The other topic concerning this can be found at:
http://discussions.apple.com/thread.jspa?threadID=2725608
It is a somewhat lengthy thread but may just apply to your situation.
Anyways I will see if I can call on some better help for you. Hang in there. Best to arm yourself with enough info before contacting Comcast so they might know what you are dealing with fully.
littleshouders
edit: I have posted for some extra help for you that may have a better idea of what's going on if it is your ISP and their modem and how it handles the IP address causing Safari and iTunes not to connect. Hang in there it may take awhile but I'm sure someone will pop in to help.

How to enable a disabled iPod that won't connect to internet

trying to enable my disabled 5th generation iPod touch. I have tried connecting to iTunes on the computer, which I couldn't get it to do anything. I then tried using the "Find my iPhone" website and erased the iPod. However, I got a message that says "This iPod will be erased when it connects to the internet". How do I connect a disabled/locked iPod to the internet/wifi while it is waiting to be erased because it won't connect to internet/wifi?

Disabled
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Forgot passcode or device disabled
If recovery mode does not work try DFU mode.
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: Back up and restore your iOS device with iCloud or iTunes
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode.

New computer won't connect to internet

I just got a new hp pavillion computer and it won't connect to my wireless. The details say something about IPv6 connectivity having no network access. I'm sending this from a borrowed Nook Color and my wireless is working just fine. Can anyone please help me?

Sorry about that; it's an HP Pavillion 20. However, after calling everyone under the sun, I found out that my router was too old (bought in 2004) so I went and bought a new wireless router. I'm online now and everything is great.

Won't connect to Internet explorer....just got this computer a week ago brand new

I just got this computer brand new a week ago. It started trying to watch vid on the net and it workstation show the picture. Then 2 days later it won't connect to Internet explorer at all. I'm so frustrated I mean how is this possible to have problems already. If I can't fix this tomorrow I'm taking it back. Please help thank you

Before you go there call your provider first and have them check the provisioning on the phone. They will ask if you did this when you go to the Genius Bar.

I'm not familiar with your router but are there any buttons on the front or back of it because sometimes you need to pair the router in order for your PC, laptop, phone or iPad to connect wirelessly with it?
From the routers I have used there are normally two buttons on the front or back (apart from the power button), pressing one of them allows you a few minutes to enter the required password on your iPad. Best look at the instructions for the router.

Touch won't connect to my wireless network

Sometimes my touch won't connect to my wireless network even though settings show it connected with good signal strength. When I go to the main screen the signal strength icon (upper left) doesn't appear. Any ideas?

Try:
- A reset. Nothing will be lost,
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears
- Powering off and then back on the router.
- Reset Nework settings: Settings>General>Reser>Reset Network Settings

ATV2 won't connect to my wireless network.

My ATV2 won't connect to my wireless network, although the network shows up in the list of networks and I'm using the correct password. A laptop approximately 1 foot away connects wirelessly to the network. ATV has worked in the past - haven't tried it recently. Tried reset - didn't help. Any suggestions?

If your wireless router is setup to use WPA or WPA2 security then you need to make sure you match this within your Apple TV device.
You probably already know to match case sensitivity in your password.
