My computer won't connect to the Internet

I just moved home and my computer won't connect to the Internet. All my other apple products do but there is just an exclamation point where my airport symbol is. How can I connect my computer to my Internet?

Some of these you may have already tried.....
Change your router channel. Sometimes this is all you will have to do.
Power cycling the router. Read the router's user manual or contact their tech support for instructions.

Highlight Airport
Click the Assist Me button
In the popup window click the Diagnostic button.
System Preferences/Network- Unlock padlock. Highlight Airport. Network Name-select your name. Click on the Advanced button. Airport/Preferred Networks-delete all that is not your network.
Place a check mark next to "Remember networks this computer has joined." Click the OK button and lock the padlock. Restart your computer.

Vista computer won't connect to the internet

Hello,
I have and airport extreme base station. It connects to macbook; Xbox 360 2 Panasonic network cameras (these only accept WEP) and a Dell Laptop runinng windows 200X(not sure which version)
I am unable to get to the internet with my HP desktop running Vista it keeps telling me I have local only access.
Can anyone help?
Airport Extreme version 7.4.2

My router is not an Airport Extreme (just a standart Actiontec from Verizon Fios). I have the same issue with XP.
Try to disconnect WEP and see if it works better. If it does (as I suspect it), try to enable WAP.
My bottom line is the issue may have nothing to do with Airport extreme.
If what i propose doesn't work, try to desinstall airport utilities and bonjour and re-install them as it has been suggested before:

Installed iTunes 10.5 but after I restarted my computer it won't connect to the Internet. All other computers in the house connect to Internet just fine. Help!! I Did all the regular modem diagnostics but that computer won't connect and it's a hard wire connection, not wireless (too far from the wireless signal). Is anyone else having this problem?

Safari won't connect to the internet (but computer is)

Today,
None of our Macintosh (by Apple) devices will connect to the internet. Actually, only Safari says it won't connect to the internet.
If I run Terminal on our Macbook, I can ping yahoo.com, google.com, etc... Also, Skype works just fine. However, when we run Safari, no web page will load and we get the error screen saying that the computer is not connected to the internet. Running diagnostics (forget where it's located on the computer) says we are indeed connected (which I could tell from Skype and pinging).
Coincidentally, neither our iPhone or iPod can get to any web pages on Safari when connected to our wireless router. Using 3g network they access web pages fine. Our PC has no internet troubles today whatsoever.
Any idea why Safari doesn't work? Unfortunatley we don't have Firefox or Chrome on our Macbook to test it out, not sure how to download those without being able to access their respective web pages.
Thanks!

Try turning off the router for 5 minutes, then turn it back on.
Restart your Mac as well as the iPhone and iPod.
If that doesn't help, on the Mac, go to /Library/Preferences/System Configuration
Move all the files from the System Configuration folder to the Trash.
Now on your iPhone and iPod tap Settings / General / Reset / Reset Network Settings
See if Safari will load pages.
If not, on your Mac, go to System Prerferences - Security.
If the Firewall is turned on, turn that off. Restart your Mac, Try Safari again.
Since you can access the net with 3G, it's got to be your Wi-Fi.
System Preferences / Network / Assist Me is where you find Diagnostics.
Make sure all the light are green. If not, click Continue.

My 1st Generation time capsule won't connect to the internet thru a new motorola sb6121 - get continuously flashing yellow light. Using a router in between the modem and capsule yields good but slower connection to internet. Any thoughts?

My 1st Generation time capsule won't connect to the internet thru a new motorola sb6121 - get continuously flashing yellow light. Using a router in between the modem and capsule yields good but slower connection to internet. Any thoughts?

Thanks for your response
Let me give the history - I started with an Apple Express being fed thru a D-Link EBTR 2310 cable Router from an RCA DCM315 Modem (Pure). Comcast service all the way.
Got the 1st generation TC in 2008 and merely replaced the Airport Express with the TC. Worked ok
A year or two ago I did try removing the modem and feeding the TC directly from the modem. Resulted in the same condition I have now - Continuous flashing amber on the TC. So I put the router back in the chain.
Some time later, at the recommendation of a Comcast rep, I replaced the router with (a Belkin F5D 5231) to see if speed and dropout problems would be improved. I thought it helped some at the time but now I am not so sure.
Last week I decided to see if a new modem would help with download speeds. So I got another pure cable modem (Motorola SB 6121- high on the Comcast recommended list).
Got up and running easily with Comcast help and with the modem connected directly to a computer.
Next I put the TC in the link and again could not get past the TC continuing to flash amber. Although I did get connected to the internet with this configuration I lost connection two both of my printers - one connected by USB and the other wirelessly to the TC. Again everything works fine when I put the Belkin router back in the system.
However with the router in there, the modem shows the downstream connection to be 10/100 ethernet speed. (Modem light changes color for indicating speeds.}
I have gone thru all of the combinations of powering down/ up, but all stays the same.
I can live with what I have but something still doesn’t seem right.
Thanks again

My airport extreme shows a green light, but won't connect to the internet.

I have an airport extreme, and it stopped working one day, so I reseted it and it's not connecting to the internet now. It's showing a green light, however, it won't connect to the internet. I live in an apartment complex, so I don't have a cable modem. The router is directly connected to the wall via ethernet. I had the ports checked by connecting the ethernet cord directly to the computer, and the internet is working fine. I tried resetting the router, but it still doesn't connect.

Your problem is typical Yosemite network.. just reboot the Time Capsule.. no luck reboot the network.. do a restart in correct order.. modem.. wait 2min.. TC .. wait 2min.. clients.
No luck then do a full reset of the TC and setup in a way that Yosemite can cope with.
Start from a factory reset. No files are lost on the hard disk doing this.
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 for basestation and TCwifi wireless name.
If the issue is wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round. ie plan on a first and second round of changes to fix this.. hopefully.. I will point out other steps that can be round2.
2. Use all passwords that also comply with 1. but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. If the TC is main router you can skip this point. This is only an issue when the TC is bridged.
Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
5. Mount the TC disk in the computer manually.
In Finder, Go, Connect to server from the top menu,
Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only. Do the same for ethernet if you use it.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
You might need to do some more work on the computer itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
Tell us how you go.
Someone posted a solution.. See this thread.
Macbook can't find Time Capsule anymore
Start from the bottom and work up.. I have a list of good network practice changes but I have avoided Yosemites bug heaven.
Yosemite has serious DNS bug in the networking application.. here is the lets say more arcane method of fixing it by doing a network transplant from mavericks.
http://arstechnica.com/apple/2015/01/why-dns-in-os-x-10-10-is-broken-and-what-yo u-can-do-to-fix-it/
Same thing applies to the Airport Extreme or the Express if used as router.. just replace TC in the instructions with AE.

Brand new HP Stream 7 won't connect to the internet

Took out my brand new HP Stream 7 tablet and set it up - and it won't connect to the internet.
Nothing obvious, but it reports that Wifi hardware can not be found.
I'm sure it's a driver problem - but since I can't get to the network from the machine - not exactly sure how to proceed (or whether its worth the grief - since I can just package up the box and return it).
If I go to the Control Panel - Devices and Printers - it shows a Device with my computer name on it, with a warning graphic indicating a problem, and when I click troubleshoot it tells me there is a problem with the Realtek Bluetooth UART Bus driver and offers to reinstall it again, but when I try I just get an error message telling me there's a driver problem and that the issue isn't fixed.
Have to wonder if anyone actually tests this stuff or whether they just ship it out without worrying about whether or not it works.

Hello shaw44:
Have you tried disabling and reenabling the adapter? Have you run the HP Support Assist which will perform some tests and it also may reset the adapter for you?
Another option is to uninstall the driver from the control panel on the desktop using Device Manager. Windows should uninstall the driver from there. Then, you can click "scan for hardware changes" and it should reinstall the driver.
As a last resort, If you were to get a mini USB to USB adapter or a male to female adapter (to use with the charger cord), you could download the file on anther device, transfer it to a USB flash drive and then copy it onto your Stream 7 tablet.
Hope this helps.

My macbook won't connect to the internet even though my router/connection is fine

Two days ago my computer was fine. Since yesterday it won't connect to the internet. I've been in touch with my service provider and determined that my router is fine and everything is correctly connected. I've rebooted my modem, restarted my computer, taken dhcp offline and put it back on, repaired disk permissions... Not necessarily in that order but nothing had work. Does anyone have any suggestions?

We've determined, then, that you use your cable rather than wifi for your signal. Approach this in an organized way:
1. ISP. Check your ISP's webmail to make sure you can send and mail email using the webmail interface. If you can, that means your ISP can still send and receive emails - if only on webmail. Useful if your normal email is malfuctioning, like now.
2. Modem. Unplug and reconnect your modem, and make sure the connection is snug.
3. Cables. Make sure all of your cables and plugs are connected; it's easy to disconnect an ethernet cable while cleaning, or after random kicking.
4. Connection wizard. Go to Mail/Window/Connection Doctor, and take down the results.
Most of the time, you can trace the problem after following these steps. If there's still no luck, provide detailed info on your results.

IMac sees the ethernet but won't connect to the internet

we had a power outage that crashed the imac. now it won't connect to the internet. the imac can see the ethernet connection. we have several other apple and dell devices that all see the internet so it's not cabling or hardware. it's a cable modem connection that uses automatic DHCP configuration. I've created a new Location setting with no change. I'm assuming that there is a corrupted file since all the other systems connect fine. any idea which one it may be or what else I should be looking for?

Shot in the dark, but did you try an SMC reset?
SMC Reset
Shut down the computer.
Unplug the computer’s power cord and disconnect peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.

Why do I see: iTunes Help is unavailable because your computer isn't connected to the Internet. IE9 works fine but iTunes does not connect to the store.

I have tried 4 days to get iTunes 10.4 working on my Win7 x64 machine. I purchased a new iPhone4 and after syncing it the first time, I can't connect to the iTunes store.
When I try to run iTunes Help, I get this message "iTunes Help is unavailable because your computer isn’t connected to the Internet." However IE9 and Google Chrome run as always...... no connection problems.
I have already uninstalled IE9 x64 and iTunes 10.4 x64 and reinstalled but still the same. I followed all the instructions I could find about firewalls, ports, SSL etc.

My MacBook Pro won't connect to the Internet, but my phone and PC will.

My MacBook Pro won't connect to the Internet. My iPhone has no problem doing so, and neither does my PC. I think it's something to do with my DNS, but I'm not sure. My network connections say that both my Ethernet or FireWire are failed. What's wrong with my MacBook? Is there a simple way to fix this?

MacBook Pro won't connect to the internet after standby

Hallo all,
I have the following strange problem with my macbook pro:
- after going in stand by and returning in operating mode the mac won't connect to the internet, I have to follow the procedure in order to retry to connect but It does'not work. Go in network preferences, try to change the DNS, use and not use DHCP and so on but nothing change.
- Mac is working in ethernet, I can see other macs and pcs
- When I change the network to connect, same problem even if I turn off the mac.
I have the same problem with Iphone !!!!
I have linksys router and modem but I think that the reason could be a setting in mac.
Anyone can help me???

I tried re-installing Mountain Lion 10.8.3 but it didn´t help.
Assuming your can access email ok ?
First, install the OS X Mountain Lion Update v10.8.4 (Combo)
Then restart your Mac. That will reinstall any missing system files.
Then try Safari.

My iPod Touch 2nd generation won't connect to the Internet

After restoring my iPod Touch 2nd gen to factory settings because that's what iTunes advised me to do after doing the iTunes update a week ago, my iPod won't connect to the internet anymore. I was able to connect to our wifi but it won't go to any website, to iTunes, etc. I'm 100% sure the problem isn't our wifi because I'm using it right now with my laptop so it's not the wireless problem. Before restoring my iPod to factory settings iti has always worked and I never had a problem connecting it. I tried restoring it again but it still didn't work. I already also reset our router but still no luck. I wish someone could help me asap!! Thank you.

You can try:
- reset:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Power off an then backon your router
- Reset network settings: Settings>General>Reset>Reset Network Settings
