La connection wifi fonctionne mal Wifi connection fails

The wifi connection does not work (after working perfectly). I cannot read or send mails and go to the internet. But it works fine with an ethernet cable. Yesterday, I reinstall Yosemite. It allows me to restore a good wifi connection. But after one day I have the same symptom. Wifi connection is no more active or useful (i am connected to the wifi network but nothing happens)

What does Wireless Diagnostics show?

Macbook pro fails to auto connect Internet after rebooting wifi router

My macbook pro with retina can’t automatically connect to wifi after the wifi router was rebooted.
There is exclamation mark on wifi sign. As the picture shows, when I clicked the wifi sign, it shows no Internet connection. However, It is strange there is a tick in front of my wifi name. Moreover, in preference set, it shows a confused self-assigned IP address 169.254…(showed in picture). In order to use wifi, I had to turn wifi off, and then turn it on. And the correct IP address for my mac should be 192… (showed in picture).
I had tried to delete my preferred networks and tested macbook in my friend’s home, but it still failed. This bug happens in my friend’s macbook pro with retina (same to mine) and macbook air. However, the previous version, Macbook pro (not retina), has no this problem.
This happened just when I reboot the router. It is normal working (connect automatically) when I come back home. Appreciating for any way to solve it!

I have no clue of what an Airport antenna is either. I know my Airport Extreme does not have one.
Try the basics first:
Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.

Want stream Netflix to blueray via Airport Express wifi. The blueray finds my wifi but the wireless connection failed - said, Ensure DHCP server is enabled on router and restart router. Don't think I have DHCP server. Suggestions anyone?

Want to stream Netflix to blueray player via my existing Airport Express wifi. The player finds my wifi but the wireless connection fails - says, " Ensure DHCP server is enabled on router and restart router." I don't think I have a DHCP server. Suggestions anyone?

I can't speak specifically regarding LG, but the Whole Home feature on Direct TV (record a movie on one DVR and watch it on another TV in another location) just won't work with wireless, and I have a strong fast connection at 300 Mbps. Ethernet works perfectly.
Few audio/video products will accept "n" wireless at 5 GHz. I suspect that your LG accepts a 2.4 GHz signal, which would top out at 130 Mpbs.
If you are trying to stream High Definition video, especially at 1080P, my opinion would be that it is unlikely that you will be able to do so reliably using wireless.
Perhaps another user who has figured out how to do this will post with some input.

TS1398 My iPhone 4 won't connect to my home WiFi, but all my other devices are connecting to it just fine. Please help!

Hey everyone, I have been having this problem for about a day or two now. I have an iPhone 4, and have iOS 7.1.2. Basically, my iPhone will connect to my home WiFi sometimes, but it randomly loses connection and won't connect for hours upon hours. I have tried turning it on and off multiple times as well as resetting the network settings. I know that it is not my network's problem because a member of my family has an iPhone 5S, and it works fine with the WiFi, along with all of my other devices. This issue is getting very annoying as I don't like to use my cellular data at home since it is limited. Please help me!!

Does the iOS device connect to other networks? If yes that tends to indicate a problem with your network.
What happens when it fail to connect?
----- 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.

Why can't I connect to my home WiFi after the 8.3 update?

I have updated my iPhone 6 to the latest iOS 8.3 and now I cannot connect to my WiFi at home, why? I've done a clean install and rebooted my home router and still no connection. However the device does connect to my workplace WiFi. All my other devices are connecting to home router as well.

Do you get an error message?
Reboot your router again, but this time do it by removing all power for about 30 seconds.
If it still doesn't connect and doesn't display an error, wait 1 minute after selecting the SSID on the phone, then go to Settings/WiFi and tap on the i next to the SSID. Look at the IP address. If it begins 169.254 then it's a router problem; the router has failed to assign an IP address to the phone within 30 seconds of a request from the phone. The phone then self-assigned an ad hoc IP address.

WiFi Connection timeout error, but still connecting

Since upgrading to Lion I've been having a strange problem. When I connect to a new WiFi hotspot I've been getting an error message suggesting that I have failed to connect, but in reality I have been connected. This happened today at an Apple Store, an office, and when I returned home. It might be related to trying to connect right after waking the computer from sleep, but this never happened with Snow Leopard. Any ideas?

How far do you get in Network Diagnostics? Any difference if you disconnect all other wireless clients?
Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
Enter the name of your wireless network in the search box. You should have one or more "AirPort network password" items with that name. Make a note of the name and password, then delete all the items. Quit Keychain Access. Turn Wi-Fi off and then back on. Reconnect to the network.

MBP does not connect to a hotel WiFi

Hi All,
I'm here in Germany since 6 days. My MBP is not connecting to a free hotel WiFi. The Airport shows full bars but the webpage is not opening. Then, i tried to restart the machine but i didn't work out. The Network Diagnostics shows that every thing is GREEN but the internet and server, they are RED (failed). However, I can join the same network using my iphone and other Windows laptop.
Now, about the diagnostics,
-In the 1st step, I choose the Airport.
-In the 2nd, I selected the "PARKHOTEL". The network i'm trying to connect.
-The 3rd step is the question of having a DSL or cable modem and my answer is NO.
-The 4th step is there any device connected directly like switch or router and my answer is YES.
-The 5th step is to restart the router device and click CONTINUE when it is done restarting. Frankly, i can not restart the router bcoz I'm in a hotel and i'm connecting to the internet from my windows laptop and my iphone. So, i assumed that it has no issue. So, i clicked CONTINUE and the connection singe starts rotating.
-After a while, the 6th step is about any other device i can restart as a router or firewalls or managed switches connected directly to the device that just restarted and my answer is NO. Finally, the diagnostics said "Network diagnostics cannot fix the current networking problems".
(NO RESULT ACHIEVED)
Then, I googled a pit trying to find a solution and i found the same issue. The solution was to disable the firewall and i found it already disabled in my MBP.
(NO RESULT)
In the meantime, i deleted all other networks except for the network & the wifi connection I am trying to connect to.
System Preferences/Network/Advance/Airport
And i restarted my computer.
(NO RESULT)
Finally, i found something today.
The IP address of the Windows lap is 10.1.10.xx
But the IP address of the MBP is 10.0.11.xx
I changed the IP address of the MBP manually and i got the same issue.
Also, (NO RESULT)
Any ideas? Plz..

When this happens to me (top part green, bottom red), it's always dns... At check-in the hotel should have given you some info, including the IP address of the router, and the dns if it's different than the router. You know the first 3 parts -- 10.0.11 -- so you just need to figure out the fourth. Usually it's either 1 or 253, but if it's some random address then you are not going to guess it.

My iPhone 3G won't display or connect to my home wifi network

Hello!
I have an old iPhone 3G that my dad gave me a long time ago. It had some problems, but I figured that's just 'cause it's old. But now I really don't know. One of its biggest (and only) problems is that it refuses to connect to my home wifi network. In fact, when I go to Settings > WiFi, it won't even display my network (it did once, but failed to actually connect), or any network, actually. I found once that in Settings > General > About > Network (Not Available), it tells me "SIM not provisioned". I've heard that you don't need a SIM card at all to use wifi on an iPhone, so what's going on here (in case I didn't make it clear, I do have a SIM card in the phone, and this problem occurs whether it's in or not)? Do I need to activate my SIM card (and if so will it cost me anything)? Or is my iPhone just whack?
If I wasn't clear in my question, please ask for clarification in the comments.
Thanks!

We now have two older phones that will not recognize one of our networks.

My macbook air is not getting internet connection through our home wifi It was working fine yesterday until I took the Air out of the house and used it on another wifi connection.

My macbook air is not getting internet connection through our home wifi. It was working fine yesterday until I took the Air out of the house and used it on another wifi connection. One question is how to delete some of the networks that I don't use. Would too many networks cause the internet connection to fail?
Thanks.

Would too many networks cause the internet connection to fail?
It shouldn't but sometimes deleting the list of networks actually does solve the problem you are describing. Have you turned WiFi off and then back on on the computer?

My ISP requires a http login. I can use the iPad fine if I am logged in on a PC connected to the same wifi network, but if I login on safari on my ipad, the connection drops after some time.. any workaround?

I understand that the OP failed to do research. But then, I wasn't replying to the OP. I was replying to Chris. I have Verizon. I can talk and use data at the same time with my Droid Maxx. Therefore, the problem is not just with the network. It would be technically possible for an iPhone to do that on Verizon/Sprint if Apple had chosen to use a different chip, such as the kind other phone manufacturers have elected to use.
Of course, this is probably all irrelevant to the OP's issue. It was merely a point of clarification, especially for those people who are used to being able to use both voice and data at the same time on Verizon. When they switch to an iPhone, they are often surprized at the limitation.
Best of luck.

HT3867 I am connected to the hotel wifi network, but the login screen does not appear.

Hi,
I am connected to my hotel wifi network, but the login screen does not appear. I am able to access the login page on my PC, but on the iPhone it does not appear and just tries to connect to the webpage (e.g. google.co.uk), and eventually gives up. I've tried opening pages in Safari and Chrome, but none cause the login screen to appear. I have also tried trying to log into the login page that the PC opens when connected to the wifi, but the same thing happens. I am using a iPhone 3G with the latest iOS version 6.0.1.
Is there a way to make the iPhone try to open the login page?
Ben.

I have the exact same problem as the original poster and I tried many times already the solution proposed by trstark66 and it's still not working. It's not working for both my iPad and iPhone 5. I'm using the latest iOS version available all the time. I have my iPad since 3 years and my iPhone since 1 years and I always had that problem. I'm an airline pilot so I'm always in hotels. I asked my colleagues who also have iPhones and iPads and they all have the same problems from time to time. And when I go in an apple store they all say that it's the first time they hear about that problem. I never have that problem with my PCs, my previous phone and my BB playbook. Only with my iPhone and iPad....since now 3 years...Always the same problem. I'm connected to the Hotel Network, I have an IP address but nothing popup to register with a user name, password or just to access the "I have read and accept the condition.../connect". And when I go in Safari or other Browsers, I am not redirected to a login page. All I have is a message saying cannot access the webpage because I'm not connected to Internet. I tried already hard resets, on/off Wi-Fi, automatic connexion off, forget this network, reset network setting...
My solution for now is to use my Boingo account. I connect to the hotel Network and then I use the Boingo app to connect to Internet.
But, sometimes it works the first time or suddenly for no reason.
Very funny, I was using Boingo on my ipad to write this message in my Hotel room because I was unable to use my free connection as usual. When I tried to press "Add Reply" it failed and I had the message "An error occured while trying to submit your post, please try again". The reason was that boingo was disconnected since I was taking too long to write this message. So I wasn't connected to Internet anymore. I opened a second tab in Safari and what did I see!... the login page to access the free connection from the hotel. This is crazy. Apple, you really suck with hotel/coffee hotspots... I tried for hours and nothing, now hours later I just open a new tab and it works. But tomorrow I know I will try the same and it will not work again. It shouldn't be that complicated.

Back from travelling (???) I am unable to connect to my home WiFi : impossible to turn the WiFi on. Anyone any clue ???

Hi,
Back from holiday (Thailand) where I connected both my Iphone4 And my MacBook Pro, I am unable to connect to my home WiFi. The icon "turn WiFi on" seems not to respond.
Has anyone a clue ???
Thanks

I cannot see how your travel can prevent you turning on wireless.
Did you do a full power cycle of both computer and phone?
Sorry but for phones I have no clue.. but I did find it failed to connect at times and you need to clear out all the old names.. full power off and on again and things suddenly start working.
Laptop can be same.. but apple has specific hardware testing available.
Look at doing tests.. or take them to an apple store and get both tested.
Is there other device still working fine on the home wifi.. have you power cycled that as well.

HT5569 After ios 7.0.6 update iPad won't connect to my home wifi.

I have just updated my iPad (retina display, one before the air) to iOS 7.0.6 and now it won't connect to my home wifi. I have never had a problem before. I pressed forget network and tried reconnecting. It asks for password but will not connect. Any help would be great.

Alas, this has not resolved the issue for me.
Oddly, my iPad mini (1st gen) CAN connect to the WPA2-Enterprise network at work and it connects at Starbucks (open wifi).
It fails (asks for password then "cannot join network") on my wpa2-personal-secured home network and on McDonald's open wifi network (nearest other place I could test. Honest.).
I've done the network settings reset, the machine hard reboot, forget networks, reset my router and time capsule repeatedly (obviously, can't reset McDonald's), to no avail.
I love shoddy work: nice update, Apple!

BB 9330 - turning off mobile network data services causes BIS WiFi connection to change to not connected

re: v. 6.0.0.719 bundle 3084 platform 4.4.0.560 update
1. History.
a. Received BlackBerry Curve 9330 out of the box with bundle 2333 installed (but missing Verizon Visual Mail Message app.) Installed BB Desktop Software on laptop, connected smartphone to PC, Attempted to install bundle 3084, but initialization apparently failed, phone still showing bundle 2333 installed and no VVM app. Browser app unable to connect to network. On second try was able to complete 3084 install. Still no VVM app. Now some times the browser connects, sometimes it does not. Browser not connecting appears to be BB software bug. VVM issue appears to be one for the service provider.
b. Data service is currently Verizon BlackBerry Social Messaging Data Package which is suppose to have BlackBerry Internet Services via WiFi per Verizon FAQ doc.
2. Problem. With an active WiFi connection the Browser app is not connecting via WiFi giving a error message that WiFi service is required.
Investigation found if mobile network data service was turn off in Mobile Network Options, the BlackBerry Internet Services connection status was changed from connected to "WiFi" to "not connected". Browser appears to work ok when mobile network data service is turned on. BIS connection to WiFi comes back on. Not sure at this point if web data is going via mobile network or WiFi.
I am wondering if other BB 9330 Verizon users are seeing the same symptoms.
Bill
P.S. I could not find where to report this apparent software bug. So I hope is the right place.

If you have your Mobile Network as well as Wi-Fi turned on, your phone will default to the Wi-Fi for browsing (assuming you have a strong Wi-Fi signal). Leaving both on will allow you to browse as well as receive calls and texts.
I hope that helps you.
- If my response has helped you, please click "Options" beside my post and mark it as solved. Clicking the "thumbs up" icon near the bottom of my response would also be appreciated.

IPhone 4 says connected to wifi but shows 3g connection. I've tried turning off 3g - that does enable the wifi logo, but then when I try to connect to something it changes to 2g. Tried resetting network connection in general setting.

I've tried everything.... I see this problem all over the web, but no one seems to have an answer... so I know it's not just me. Laptops and other wireless devices connecting fine, just iPhone 4 has problem.

When you say you have tried "everyihing" that doesn't provide enough information to help you, as one person's "everything" is quite different from another person's "everything". In the absence of knowing what you have tried, the following are the most common causes of this problem.
Turning off 3G will just switch you to EDGE. You can turn off Cellular Data, but that won't make it connect to WiFi if your WiFi isn't working, it will just eliminate all data access to your phone.
Easiest to try answer if it is only your home WiFi, and it works other places: Reboot your router.
Next, update the firmware in your router.
If it doesn't work with any WiFi anywhere first Reset Network settings. If that doesn't fix it, restore the phone using iTunes.
You didn't say what symptoms you got, or when you were trying to use WiFi. You do know that the iPhone turns off WiFi when the phone is on standby to preserve battery, right? So if it only fails to connect to WiFi when you are not actively using it that is normal.
