Connection problems If you can't connect to WhatsApp, this is usually caused by a problem with your Internet connection or your phone's settings. Troubleshooting Most connection issues can be resolved by doing the following: Restart your phone, by turning it off and back on. Open iPhone Settings and turn Airplane Mode on and off. Try connecting to different Wi-Fi hotspots. Make sure Wi-Fi stays on during sleep mode.

Reboot your Wi-Fi router. Contact your mobile provider and make sure your APN settings are configured correctly. Wifi worked for a while but could not search for networks and now the wifi has grayed out again. Anyone help please. Wi Fi button is grated and I cannot operate it through the settings also. Currently having 7. I have tried all the solution of reset and all.

What should I do to solve this. Pls tell me the solution. Been with out my wifi off for months now off and on.

My problem started loading on ISO 7 just like most of you. We should all be compensated and apologised to for this.

Heated the phone with hair dryer, temperature symbol came up to say phone needed to cool down put it in the freezer and hey presto it worked!!!! I went without my wifi for 7 months and then fixed it in 15 mons with a hair dryer and freezer!! Thanks for the tip! What if i will not use a hair dryer to over heat my phone. All i do is to put in a freezer is it gonna work? Or i have to over heat my phone first? Wifi not working. Tried everything under the sun, then gave up and stuck the phone in the freezer for ten minutes.

Bam, works. Crazy, but true. Just try it.

I think the phone gets hot and turns the wifi off and gets stuck or something and the cooling flips the switch back. This is unbelievable! I use an iron instead of hairdryer. Heated a cloth and covered my iPhone with it and straightaway put my phone in a freezer. Went out from shower and turned it on, and the WiFi is alive!!! Could it also be a problem with the protective covers overheating the phone? C problem. When I first heard the hairdryer thing I thought someone was joking and trying to get people to break their phones… until I read all the comments saying it worked.

That just worked perfectly…. I also had the same problem. Finally bought a new I phone. Tried the blow dryer freezer fix to get wifi going To sell my old phone and it worked!!! Thanks for the info!!! We should start a class action suit!!! Cant believe this, but the blow dryer and deep freezer method worked, as sceptical as I was. Tried the hair dryer and refrigerator cool down.

Wi-Fi still out. Can you redo this process more than once? I also would like to know if they have filed a class action suit against Apple? If so how do you join. I am on an iphone 4s running ios 7.

Wi-Fi not working on your iPhone or iPad? Here's the fix! | iMore

I tried resetting network settings, hard restarting the phone by holding both home and power button , turning airplane mode on then resetting, putting it in the freezer, ect. By just putting it in the freezer the wifi and bluetooth would temporarily work for around 10 min i tried this twice producing the same effect. I did not get a overheat warning the second time but i had kept the screen turned on while heating it up and the screen began to go black so i stopped and the screen returned to normal quickly then i put it in the freezer for around 5 min.

So strangely enough the blow dryer technique for whichever of the two reasons. Just hoping that my iphone works well till i shift to another good phone of course, no more Apples in my basket. I was having to same problems wifi was greyed out. Every now an again it would try to connect an fail, so I not having a hair dryer handy put my iphone on top of the wood heater until it over heated, when it cooled down enough. I reset the network setting, wifi is now alive an working well.

I used to use this wifi until I updated to iOS 7 with this same wifi.

Solutions for iPhone /iPad Wi-Fi issues

Thanks everyone for their posts which makes it so more convincing, thanks once again. The hairdryer worked for me. I had been out in the sun all day before the wifi became greyed out so it may have been overheated that way. Wifi was gone all the next day, heated it up with the hairdryer, got the warning message, powered it off, put in a plastic bag, into the freezer, took it out, powered up and wifi worked. Still working 3 days later so fingers crossed. Enough is enough! Bye bye iphone!

You are so annoying. Same problem here, same solution and it worked!!! I went to Apple store today and they charged me freaking bucks to replace for a new…no way!!! I already turned it off, tried to reset network settings and even all settings, yet nothing happened. Even the auto brightness thing. I also spoke too soon. Today I have no wifi and no bluetooth for my car hands free mode. I lived for 4 months with no wifi condition, and high data usage, every month, hmmmm. Finally, I played around and solved it this way.

Put iphone 4s in airplane mode. Reset phone using top and bottom hard buttons, restart phone, let sit for 10 minutes, while software reboots. Then go to settings and turn airplane mode off, go to wifi setting window, and slide the soft button to the right, should show green. It worked for me. Must be a software glitch, right apple?
