HT4628 I can't connect to my wifi. Says "No IP address" under WiFi. Please help!
I can't connect to my wifi. When I go to system preferences it says no IP address. This problem seems to be specific to my MacBook Pro as the other computers in the house get on fine. So ready to go back to a PC laptop.

My iphone suddenly can't connect to any wifi :( Please help me !!
The wifi sign appears on the top left but then the circle in front of the wifi name keeps running. I've waited for a long time and tried resetting the network but it still didn't work. Please help me if anyone knows something
Some people who experience issues connecting to or even seeing there Wireless network should follow these steps.
These steps are just a guideline and its not 100% that it will fix your issue.
Mainly, if the issue persists, its possible there is an issue with your iOS settings or a hardware failure within your iPhone or iPad, specifically the Wifi adapter.
You would want to follow these articles to do a reset & restore prior to saying it is a hardware issue.
#1: Reset: http://support.apple.com/kb/HT1430
#2: Restore: http://support.apple.com/kb/HT1414
You will need to access your Admin control panel for your router.
If you have an Airport Extreme BaseStation, you just need to open the Airport Admin Utility found in Applications > Utilities Folder.
Enter your credentials and you will have access to the settings from there.
For a PC: Do NOT use the CD that came with your router. That is used for people who do not know how to setup a router properly and these settings will not be available for you in most cases.
If you are using anything other than an Airport BaseStation:
Open a web browser:
In the address bar, type:
192.168.1.1 (Mainly used for Asus, Linksys, etc) or 192.168.0.1 (D-link,Belkin)
How to figure out what the IP address is to type in?
Windows:
Hold down the windows key, then press R. This brings up the run box. In that box type "cmd" (without the quotes) and press enter. In the black box that pops up, type "ipconfig" (without quotes) then hit enter. Your default gateway is the IP address for your router. It will start with 192.168.....
Take that number and put it into the address bar in your browser and hit enter. It will then ask you for a user name and password. For linksys, it's admin for both. If you have another brand, just google "default password for ******" replacing the asterisks with the brand name of the router. Once you have entered the correct user name and password, you're there.
Mac:
1.From the Apple menu, select System Preferences.
2.In System Preferences, from the View menu, select Network.
3.Select the appropriate port. For example, choose Ethernet for broadbandconnections, AirPort for wireless, or Internal Modem for dial-up.
4.Click Advanced... , and in the sheet that opens, click the TCP/IP tab.
The number next to "Router:" is your default gateway.
Once you get into your admin panel do these setting changes.
1.On the router change the channel for the 2.4mhz band to channel 1, 6, or 11 (recommended), rather than auto.
2.Also set that channel width to 20hz only, rather than 20hz or 40hz (Auto)
3.Make sure Security is set to WPA/WPA2-Personal. Anything else will cause issues. (of course, make sure you know your password for security)
4.Make sure to Apply/Save these settings. Sometimes the wireless connectivity will go out during this change and will come back on within 15-30 seconds.
5.On the iPhone/iPad go to Settings > Wi fi > click the blue arrow beside the network > Select Forget network
6.Go to Settings > general > reset > reset network settings
7.Power the phone off and on. Connect again

Can't connect my Ipod Touch 2nd gen to home wireless network - please help
I have just received a 2G ipod touch today and it will not connect to my home network. I have a SKY Netgear router with numerous devices wirelessly connected with WPA security. I have input the shared network key when my Ipod asks for a password but it will not connect (even if I am stood next to my router). I just get "Unable to join the network .........". I have tried connecting via the 'other' network route but still the same result. Please help.
Here's a few things you can do to get to the bottom of the problem:
- Have you ever connected to a public hotspot? The only reason I ask is this will rule out hardware problems. If you are not close to anything, download and install the free app WiFinder from the app store. Once you have the app installed, you see what networks are around you. If nothing is working, contact Apple and either visit the Genius Bar or return it Apple.
- If you have disabled encryption in your router and you are still be prompted for a password, you need to tap on that network name and tap Forget Network. And to really make sure everything is cleaned out, go to Settings > General > Reset > Reset Network settings.
- After your iPod restarts, use WiFinder to find your network. WiFinder will tell you whether or not you have encryption on or off and the type of encryption used. If it is still off, just tap the Connect button. If you have turned it back on, go to Settings > WiFi > Other network and enter your network name. You will be prompted for your encryption scheme and your password. WPA and WPA2 should have a password entered. WEP should have the hex key entered.
- If you still can't connect, I would check and reenter my password. Passwords are case sensitive.
- Assuming you have connected, tap the blue arrow (>) next to your network name. You should see your IP address, subnet mask, router IP address, and DNS router addresses, you are good to go.
- If you have an IP address of 169.x.x.x, your router is not supplying an IP address. Recommend router settings are:
SSID - on
DHCP - on
MAC filtering - off
Encryption - on and set to WPA or WPA2
DNS - automatic from ISP
Let us know what happens. -
Can't connect to the Software Update server (lionserver.t3m.private)? Please help!
Has anyone experienced this; Can't connect to the Software Update server (lionserver.t3m.private)?
I can no longer sync my iPhone as it needs an iTunes update. When I select update software and I get the error message above.If you are getting the error message "Unable to check for update" when you try an OTA (over the air update)
Change DNS Servers
Settings -> Wi-Fi
Click the blue arrow on your connected network
Delete everything in DNS and replace it with 208.67.222.222, 208.67.220.220
Try again
If this works, you will probably want to remove the WiFi network using "Forget This Network" and then reconnect to it to get your original DNS servers back. Alternatively, make a note of the original DNS servers before deleting them and replace it after you are done.
If you are getting the error message "Unable to check for update" when you try through iTunes
On your Mac
Choose Apple menu > System Preferences, and then click Network.
Select the network connection service you want to use (such as Wi-Fi or Ethernet, unless you named it something else) from the list, and then click Advanced.
Click DNS, and then click Add at the bottom of the DNS Servers list. Enter the IPv4 address for the DNS server.
208.67.222.222
208.67.220.220
You can Google Public DNS if you want

My Ipod touch ios version 6.1.3 will not allow me to connect to my wifi, Please help me!!
My ipod touch ios version 6.1.3 will not allow me to connect to my wifi. I tried rebooting my wifi router, refreshing my ipod, resseting the networks and manually logging into my wifi. Sometimes it will go through for a brief moment, but the wifi connection will ultimately disconnect. Each time i try to connect to my wifi afterwards a small pop up will say "Unable to join the network". Please help. it's really annoying and frustrating.
Thank you Carolyn Samit, but nothing is working.
I've restored my ipod both to a backup and back to factory. I know the password is correct,
the router is the newest version (and it's plugged in and on), my ipod is updated, i've turned my wifi settings on and off, i've turned the ipod off and on. No luck yet. I've been working on it for hours now. About ready to sleep on it...maybe some luck will find me tomorrow...
Still in need of dire help. -

My Hp deskjet won't connect to my wifi, please help!!
I recently bought an iPad so I bought the hp deskjet 3510 to be able to use AirPrint with the iPad. But the printer won't detect a wireless signal. It just keep blinknig the little blue wifi icon on it. I have the printer right next to my router, so there should be no problem. I don't have a desktop or laptop to use, just the iPad. I have googled a million times and it's getting me no where. Please, help!!!
This printer doesn't have a wireless setup wizard, so getting it on the network will be a bit of a chore unless you have a computer. You don't happen to have a computer and a USB cable do you?
-------------How do I give Kudos? | How do I mark a post as Solved? -------------------------------------------------------- -
My ipod touch will not detect any wifi signals but others devices such as my laptops; do connect without a problem. I restored my ipod and updated it and still no wifi signals are being detected.
Go to your ipod touch wireless settings chose your network and right beside there is button looks like ">" click on that check the dhcp what IP are you getting? do you get any ip? if you do your ipod touch should work with wireless no problem. Also, you may have to enter wep key again. After that it shou,d save your device

How do i update 10.5.8 if my macbook does not show any software updates?
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
Snow Leopard General Requirements
1. Mac computer with an Intel processor
2. 1GB of memory
3. 5GB of available disk space
4. DVD drive for installation
5. Some features require a compatible Internet service provider;
fees may apply.
6. Some features require Apple’s iCloud services; fees and
terms apply.
Upgrading from Snow Leopard to Lion or Mountain Lion to Mavericks
To upgrade to Mavericks you must have Snow Leopard 10.6.8, Lion, or Mountain Lion installed. Purchase and download Mavericks (Free) from the App Store. Sign in using your Apple ID. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
OS X Mavericks- System Requirements
Macs that can be upgraded to OS X Mavericks
1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
Model Identifier 5,1 or later
3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
7. Xserve (Early 2009) — Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?
See App Compatibility Table — RoaringApps.
Upgrading to Lion
If your computer does not meet the requirements to install Mavericks, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
Lion System Requirements
1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
or Xeon processor
2. 2GB of memory
3. OS X v10.6.6 or later (v10.6.8 recommended)
4. 7GB of available space
5. Some features require an Apple ID; terms apply. -
My ipod touch will not connect to my wifi, Please help!
So last night I decided to turn off my router just by unplugging it due to my sister keeping me up. So basically when it got plugged in, everything besides the wireless internet works. I think it is more of the router than the ipod. Any information that you need I will gladly tell! I haven't had this problem before.
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
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- 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.

I have a MacBook Pro. My mac can detect wifi. But will not connect anywhere. I did get connected via TCP/IP settings but I can't connect to any wifi anywhere. Network diagnostic has a green light for wi-fi and wi-fi settings. Red light for the rest. (Network settings, ISP, Internet and server.)
Hello NotAppleSavy,
Thanks for the question. After reviewing your post, it sounds like the computer wont connect to networks. I see you have used network diagnostic. I would recommend that you read this article, there are a lot of other things you can do in this article that may be able to help you resolve or isolate the issue.

Can't Connect to any WiFi network
I just got my iPhone yesterday and I'm already having a serious problem,I can't connect to any WiFi networks.
I can see the networks around me and I can select networks that I've setup and I know are open or I know the security passwords, I can even enter the network passwords for the ones that require them and it accepts them without complaint. When I select a network I get a little check mark next to that network which I assumes means it should be connected to that network. However, the iPhone never actually connects to them, i.e. no IP address, no router no nothing in the network settings screen for each network, and always appears to the using the Edge wireless network when accessing the internet.
I've tried DHCP and static IP but neither works.
I updated the phones software to 1.1.4, has anybody reported problems like this with this or any version of the software.
Any help would be much appriciated.
If I can't get this resolved today I'm returning to the AT&T store tonight for a new one.
Thanks
Matt S.theevilone,
I have personally used an iPhone with routers from D-Link, Netgear, Linksys, Apple and Belkin.
Some routers, regardless of manufacturer need to have their firmware updated. Generally speaking if you look at the release notes, the same updates that resolve issues with DHCP for game systems and PDAs, also resolves them for the iPhone.
In addition hardware or MAC address filtering can cause issues where you connect to the network and not get DHCP.
Hope this helps,
Nathan C.
