MBP won't connect to the internet via my home network

I recently moved to a new apt and I have the same cable provider as in my last apt. The internet is up and running and my imac connects to it via my AE router while my mbp doesn't. my iphone also cannot surf the web using the signal coming off my router. anybody know why this is happening?

Ok. My iPhone's ip address is 10.0.1.2 My iMac's is 216.164.210.117
I should let you know that I recently moved 2 weeks ago from one apartment to another. When I lived in my old apt, everything worked fine. My MBP, iMac and iPhone were all able to use the internet wirelessly. I just recently got my internet hook up on Saturday and since then things have been going awry. For example, when I originally wrote up this post, my MBP couldn't connect wirelessly to the internet. Without me doing anything, 2 days later it works and since yesterday, I haven't been able to connect wirelessly to the internet with my MBP. My iPhone never connected to the signal at home since the router has been hooked up. Does my IP address have anything to do with it?

Hello Rattisate,
Sorry to hear you are not able to connect to Wi-Fi on your MacBook Pro. I would be concerned about this too. You can find information on how to troubleshoot this in the following article:
Troubleshooting Wi-Fi issues in OS X Lion and Mac OS X v10.6
http://support.apple.com/kb/HT4628
Follow the steps in the section labeled, "Symptom: My Mac does not connect to the Internet."
Thank you for posting in the Apple Support Communities.
Best,

Hi, my ipod (2nd gen) won't connect to the internet via Safari or through apps but my email does work. Any ideas without needing to reset the ipod?

Hi, my ipod (2nd gen) won't connect to the internet via Safari or through apps but my email does work. Any ideas without needing to reset the ipod?

- Have you tried when connected to other networks? Maybe the router is blocking the ports used by Safari and the other apps.
- What kind of network are you using? a personel or bussines?

Powerbook won't connect to the internet via Ethernet?

Hi
Just recently, my 1.5 GHz powerbook won't connect to the internet with an ethernet cable. It connects fine at home when it's connecting through the airport, but then I try to use it with the ethernet cable it tells me that "Ehternet may not be able to connect because it has a self assigned IP address" But I didn't assign it an address, OS X configured it. Thanks in advance for any help.

And your settings in:
System Preferences/Network/Show: built-in Ethernet/
(Tab): TCP/IP; configure IPv4 is set to "DHCP"?

2010 MBP Won't Connect to the Internet

Hi I have a 2010 15" MacBook Pro. I am running Mac OS X 10.10.2 . All of a sudden yesterday it stopped connecting to the internet. I did the obvious things such as restarting my router, re-connecting to my Wi-Fi, restarting the computer, but nothing as worked. I logged onto my Windows 8 Boot Camp partition and the Internet is working fine. Do you have any suggestions on what to do? Again, it's working fine in Windows 8 so it can't be a dead wireless card.

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.
Be sure to test on more than one Wi-Fi network, if at all possible. A desktop computer can be tested with a mobile hotspot, such as the hotspot created by a cell phone. If the problem only exists on one network, then the access point of that network should be the focus of your attention, not the computer.
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 Energy Saver pane in System Preferences and unlock the settings, if necessary. Select the Power Adapter tab, if there is one. Uncheck the box marked
Wake for Wi-Fi network access
if it's checked.
Step 5
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 6
In the Wi-Fi settings, select
Advanced... ▹ TCP/IP ▹ Configure IPv6: Link-local only
Click OK and then Apply.
Step 7
Reset the System Management Controller.
Step 8
Reset the PRAM.
Step 9
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. Turn Wi-Fi off and then back on. You'll be prompted for the password when you reconnect. Save it in the keychain.
Step 10
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

MBP Won't connect to the Internet

Hello,
As of a few days ago my MBP(Summer 09) will not connect to my home internet. It picks up the wireless network, but always self assigns an IP address. I have full bars indicating a strong signal. I have used this connection for almost a year and now it won't work. It still won't work when I plug it in dirrectly to the modem. The little ball next to Airport or Ethernet turns green but the pages won't load. I have read this problem a few times online but have seen no solution. Any help is apperciated. I am running on 10.5.8

Alright guys I was able to finally fix it by going to Security -> Firewall -> Accept all incoming connections. But my question to you NOW is, is this safe to do?

Replacing an Airport Express with a Time Capsule but it won't connect to the internet.

Hello, I hope somebody can help.
I am trying to replace an Airport Express with a 2TB Time Capsule but it won't connect to the internet, via an ADSL modem.
I have tried everything I can think of, powering down all devices, re-setting all devices, but nothing seems to solve the problem.
When I first tried to set up the Time Capsule, there was an option to replace the Airport Express using the same settings.
But there were repeated error messages of 'No DNS Servers' and 'PPPoE server couldn't be found'.
I also had messages that the password for PPPoE wasn't correct, but when I plug the Airport Express back in again, everything works fine.
What could the problem be?

99% of issues with authentication are wrong password or wrong username.. eg it can be strange like the user name is missing the domain.. whereas the Airport Express works fine without it.
Ring your ISP and make doubly sure you have exactly the correct username and password.
If it still doesn't work, put the adsl modem back into router mode and try it again directly on the modem.. if it works ok on the modem but fails on the TC that is possible and can be caused by pppoe client using incorrect authentication type, CHAP or PAP which the TC does not allow you to select AFAIK.. some ISP do not give enough time to get the router to switch on auto to the correct authentication method.
In the end run the modem as router and bridge the TC. It will work just as well for most installations in bridge as the modem in bridge.

Curve 9380 unable to connect to the internet via wifi

I'm using curve 9380 and unable to connect to the internet via my home wifi, there is no blackberry logo beside the wifi signal symbol. I don't have this probelm if I'm using my laptop or curve 8520 to connect to the internet via the same wifi router. Please help. Thank you.

Check firewall, if you're on wifi then try ethernet to rule out interference. It is likely a network issue.

If your not hearing dial tone you might have your phone plugged into the wrong port. Most modems have 2 outlets, one is labeled line ( that is the one you should have plugged into the jack (RJ11C). If that's correct, query the modem and see if it tests OK, you may have a defective modem.

My iphone 5 won't make a call when i fail to connect to the internet via 3g

My iphone 5 won't call when i fail to connect to the internet via 3g.
At work i dont have wifi i have 3g, if i launch say the sky go app,or the iplayer, sometimes they work and everything is fine...sometimes they wont load as 3g for whatever reason cant get a connection at that particular time........ if i then try and make a call the call will fail. I've experimented 25 + times and this is definately the cause.
(note: when the 3g connection does work, the phone has absolutely no problem calling people)
Anyone had this problem?
Even better has anyone got a solution?
Thanks,
Nick.

Are you sure that the carrier's signal is strong where you are having this problem? Certain building structures and locations have poor cellular signal strength and this often results in the "No Service" indication. Are other users able to get service in the same locations where you have problems?

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.

HT4628 My Mac Air OSX10.8.5 won't connect to the internet as it says it has a self assigned IP address and thus cannot connect to the internet. I can only connect to a network by manually typing in the configuration specs. Please help.

My mac air OSX10.8.5 won't connect to the internet. It says it has a 'self assigned IP address and therefore cannot connect to the internet'. Network diagnostics is unable to the solve the problem. It happened suddenly for no reason and now I cannot connect except by typing in the configuration settings manually. Please help me!

Use the Airport Utility or log into your wireless device via http and ensure the DHCP/NAT service is enabled. If accessing via HTTP, you will need to manually set an ip within your local subnet (eg: 192.168.0.x).

Spotify won't connect to the internet?

At the moment, Spotify is the only internet-based programme on my laptop that won't connect to the internet. I've tried everything that usually makes it work, e.g. logging out of Spotify and logging in again, turning off the internet via my laptop and switching it on again and turning the internet off via the router and a plug... but nothing seems to be working at all. Spotify for Internet servers like Google Chrome work but not for desktop. Why?

Spotify does the same here. Device Android HTC m8 mini 2.
