MacBook suddenly can't connect to wifi

I have been using the same wifi at home for three years, and suddenly today I am not able to connect. My iPad and phone are all able to connect to the wifi except my laptop. It started when I was in queue for playing League of Legends, but I had to force quit out when I couldn't load. immediately afterwards is when the problem started. The airport sees the router, but can't log in to it. I've tried everything to resetting the router, renewing my DHCP lease, deleting all the airport plists in Library/SystemCknfiguration. It seems like I can't log in to any networks as I tried connecting to my mobile hotspot which did not work.
My MacBook is late 2014 15 inch on 10.9.4 Mavericks.
Any ideas to fix this?

Hi,
Do you have an Airport base station, such as Airport Express or Airport Extreme, or a third-party wireless router?
If a router, unplug it for a while and then reconnect. Try Airport Utility again.

MacBook Air can't connect to WiFi; iPhone, iPad can

I'm a pretty experienced Mac and WiFi user, but this one has me stumped.
I was recently waiting for my car to be serviced and tried to connect to the dealer's free WiFi network (Sonic via ATT broadband). My iPhone 4s and my iPad3 had no problem signing-in to Sonic (OK'ing the terms) and accessing the internet, but I could not connect using my MacBook Air (model 4.2). I tried a number of things (e.g., refreshing the DHCP address, turning wifi off/on, etc.) - none worked.
The person at the dealership said, "Macs seem to have a probelm connecting."
FWIW, I have no problem connecting to my home, my work, and other WiFi networks on any of these devices.
Any ideas about why my iPhone and iPad can connect to the Sonic WiFi and my MacBook Air can't?

Ipad2 suddenly can't connect to wifi - password help ?

Hello
We've had an ipad2 for about 2 months. We got it connected to WiFi fine by putting in the security key from the Livebox modem and everything was hunkydory. Then we went on holiday for a fortnight and when we got back, there was no way of connecting it to WiFi. It asks for the Livebox password, a maximum of 21 characters. The security key is 26 characters long so it isn't that. I've entered every password we own (from the original ISP/Livebox signup letter) and none of them work. I read in a few places online about changing the security option from WPA to WEP, I did all three options but nothing changed. I also rebooted the modem - no change.
I phoned Orange (our internet provider) to ask for help and they said that the password is always the security key. When I said that that was too long, they said that there is no such thing as a Livebox password so they couldn't help me.
There are lots of people asking the same question on the Orange forum (I'm in France) but no solution. Some people said that it comes back all by itself after a few days but it's been 10 days and we still can't connect.
Help !! Thanks in advance !

Does the Router have a common default SSID like "linksys" or such?
Go to System Preferences
Click Network
Highlight AirPort and click Configure...
Choose “By default, join: Preferred networks”
Select your access point and Remove your access point with the minus button.
Launch your keychain access in Utilities and delete your access point keychain entry.
Reboot
Go back to the “By default, join:” page and click the plus this time to add your access point. Enter the correct password, save, reboot.

I have a macbook air, have never had a problem with it, but all of a sudden can't connect to wifi. Says "ip address fail". Any suggestions?

I've also tried network idagnostics, it can never get further than ISP. Sometimes ill get lucky and it'll connect, but the connection *****. I know the internet itself is working cause the other computers in the house are working fine. Help!

Thanks Bob, I don't know why but it all of a sudden worked a few days later. It's a mystery but at least problem solved.

Macbook air can't connect to wifi but at the same time is connnected.

Hey there fellow mac users, I got myself a tiny problem around here.
My mid 2013 mba is connecting to my wifi at home, but when it's done connecting (and shows it's connected at the network panel) it doesn't load anything from firefox, safari, steam, apps, twitter etc etc. The problem lies within my mba I think, because all our other devices, (windows laptops, android phones, windows pc's and our ipad) can connect to the wifi and actually use it.
Here's a few things I tried :
I tried turning it on and off (basic everyone does that)
resetting the router which I am connected to
creating a new wifi location
using different dhcp adresses (i set it to 8.8.8.8. to test it with google)
and as a final thing I heard one of my friends worked around with something on the hardware (a 1453 thing Idk what it does but it didn't fix it)
Is there someone with enough knowledge of internet connectivity on Macs willing to help?

It appears that you have a question about the MacBook Air.......and we handle support for the Apple AirPort Express, AirPort Extreme and Time Capsule on this forum......so you will likely get a much faster and more informed response if you ask your question about a MacBook Air in the MacBook Air support forum.
The link is just below:

If you do have a question about one of the Apple routers, we can likely help on that.

Suddenly can't connect to wifi

Wifi had been working fine on my macbook and both of my roomates' macbooks until last night, when they all stopped working. This morning one of them could connect to the internet again, but the other two can't. I've already tried restarting the router and the modem, reconnecting the modem, restarting my computer, deleting and adding "Airport" in system preferences//network, and deleting the system configuration folder and restarting. Nothing has worked so far - is there anything else I can do?

Try putting these numbers in Network>TCP/IP>DNS Servers, for the Interface you connect with...
208.67.222.222
208.67.220.220
Then Apply. For 10.5/10.6 Network, highlight Interface>Advanced button>DNS tab>little + icon.
DNS Servers are a bit like Phone books where you look up a name and it gives you the phone number, in our case, you put in apple.com and it comes back with 17.149.160.49 behind the scenes.

Can't connect to wifi as hardware cannot be found

Hi, I m using MacBook and all the while I m able to connect to wifi. However, just 2 days ago, I can't connect to wifi all of a sudden? When I check the wifi icon on the desktop, it says "wifi no hardware installed". Tried going to System Preference to turn it on but the button does not respond to on the wifi. Does anybody know how to resolve this? Thank you

Might be corrupted network preferences ...
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
/Library/Preferences/SystemConfiguration
Click Go then move all the files in the SystemConfiguration folder to the Trash.
See if that makes a difference.
Your Mac will generate a new SystemConfiguration folder for you.

IPhone can't connect to wifi at home

periodically my wife's and my iphone can't connect to wifi at our house. We do have many devices connected - about 7-9 - but it seems like the iphone is at the bottom of the pecking order. No other devices have this problem. Sometimes when I unplug and replug the router it will connect to the phones. Do I have a bad router?

From personal experience, I have learned that all Apple devices are good for detecting netowrking/wifi issues. My home wifi works great most of the time. When I start having problems with my iPhones, it will progress to the iPads, then the MacBooks, then eventually to the ThinkPads. If I resstart my router when I start having problems with my iPhones, everything else is always happy. I have even gotten tot hte point that I restart my router once a month (usually at 8:00pm on the 1st) and then I don't have any problems with any of my devices cconnecting, even the iPhones.

This happened after I connected to a store's network that has a privacy policy pop-up in wifi settings. Hope this doens't happen everytime I connect to such a netowork.

Um okay. And? What have you done to try to fix it? What error messages are you getting? Do you use WiFi or Wired connection?

Suddenly can't login to Wifi on my iPad and have disconnected and restarted router and iPad to no avail. Help!

Suddenly can't login to Wifi on iPad and tried posted solutions with no success.

Thanks, trying to figure out what the ISP might have done is difficult......kind of like trying to operate blind folded with one hand tied behind our back.
We don't like to guess at things, or worse.....get into a series of "try this" and "try that" that only lead to more frustration, but have little choice if you want to try to continue with this. Your call on that.
On your MacBook Air......
Open Finder (the smiley face at the lower left of the screen on the dock)
Open Applications
Open Utilities
Open AirPort Utility
Click on the picture of the AirPort Extreme, then click Edit in the smaller window that appears
Click the Network tab at the top of the next window
What is the current setting that you see for Router Mode?
Is it "Off" (Bridge Mode)?
If yes, then change that setting to read DHCP and NAT
Click Update in the lower right corner of the screen, and allow a full minute for the AirPort Extreme to restart, then power it off
Power off the provider's modem/router
Wait a minute
Power up the provider's modem router and let it run a full minute
Then power up the AirPort Extreme and let it run a full minute
Check the network

TS1398 have been connected to my wireless network using a netgear sky broadband router succesfully for a few weeks, suddenly can't connect, network is showing but no signal - all other wireless gadgets are connected just fine - including iphone - any idea

my ipad 4 has been connected to my wireless network using a netgear sky broadband router succesfully for a few weeks, suddenly can't connect, network is showing but no signal - all other wireless gadgets are connected just fine - including iphone - any ideas?

Some things to try first:
1. 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.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. 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
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Can't connect to wifi hotspots

After I updated my OX I can no longer connect to wifi hot spots.
I contacted apple support and they told me to put "com.apple.airport.preferences.plist" and "preferences.plist" from the library folder to my desktop and restart my computer.
I did nothing. I still can't connect to wifi. When I click net network preferences, under wifi,there is a yellow circle, not green.
Can someone tell me what the problem is? I can't work in libraries and cafes anymore!
(Macbook Air - OS X 10.9.4)

Does the iOS device connect to other networks? If yes that tend to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device 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 your 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 and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.
