iPhone 4S WIFI Issue Fix! WIFI Grayed Out In Settings Fix! (Easy) 

This is why I love RU-vid. There's literally a video for anything.

This actually worked! I've been researching this for days and finally came across your video. I was at my wits end so I decided to give it a try. I can't believe it worked! Thank you so much for taking the time to make a video and put it up for everyone to use. I really appreciate it!

Great knowledge. My daughter's iphone 4s had this same issue. Tried everything until i found your hair dryer technique and boy believe me it did work. Good job.

Thank you so much for making this video. I followed ever step on my fiancé's phone and it worked. I don't understand why someone would be concerned with your voice which is fine in the video. People should be more concerned with the info you provided.

This did work for me with two caveats, the first of which is very important. 1. Although I had the hair drier aimed at the top of the phone for at least 10 minutes, the OVERHEAT WARNING NEVER APPEARED. The phone was so hot I could barely tolerate holing it for the 3 seconds it took to power it off. The wooden counter upon which it had been sitting was also too hot to touch. I don't know at what point an iPhone 4S melts, but I was darn sure hoping not to find out with my phone! (Many years ago using an iPhone 3 as a GPS I received the heat warning, so I am familiar with it.) The lesson here is use a little common sense with the heat. 2. Immediately after turning the phone back on (after 15 minute cool-down in the fridge) I went to settings and reset the network settings. It is worth noting that I tried this 3 times BEFORE I tried the heat process, so I know it was not that alone that did the trick. Nonetheless, if you are having this problem I would suggest trying the reset first before subjecting your phone to excessive heat., because it is obviously less risky.

IMPORTANT: Thank you all for watching my video.. This really works if you do what I tell in the video. I know it sounds like BS but its legit!! Share like & subscribe people.

Hello! It worked like charm!!! I bought two screwdrivers the pentalobe and plus one, even the wi-fi antenna itself. Replaced it with new antenna, no result, put back the original, then I started yours, I would like to advise as follows: 1. Open up the back plate, take out the antenna which is just about 1 minute job, be patient in doing this, no rush that may bring up more issue to other parts. Try to make your fingers as soft as possible. 2. Put a soft tissue/napkin paper to cover the other parts of phone, especially the battery, and parts with black soft rubber and kinda. 3. Only the area where the wi-fi antenna sits on, as the wifi IC chip module lays underneath the wi-fi antenna. Put your phone into sleep mode. 4. Now "hairdressing" on to this spot of wi-fi module area don't heat up other parts, minimize risk of heating up unnecessarily other parts that hot air may strip the rubber tapes or whatever melting could be possibly too. 5. I needed about 30 seconds only to get the over heat message onto the screen, wake up the phone...message appeared. 6. Just turn off the phone, need not freeze it, physically transferring between hot and deeply cool temperature may harm the other parts too, think about it, this is not bi-metal pieces. 7. Turn the phone ON and its wi-fi too....and OPSSSS! As you wish the baby wi-fi smiles to you. 8. I tried all the way down...U Tube, up and down, downloading, etc. It is there.. Thanks anyway....

Oh my goodness four years I’ve had this phone with no WiFi and this worked!!!! THANKYOU so much

Great video! Worked perfect! Although the "IPhone is too hot" Screen didn't appear. Put it in the fridge after a couple of minutes of heating and it worked.

Thank you!. this worked. I had my last phone like this for the last 2 years, finally fixed.

Thanks you very much, im so lucky you was here and you made this. I truly appreciate this video.

Thank you so much, First I thought how come this will work,,after when I tried it really worked out....Once again Thanks.👍.

Thanks for your hope bro,I jus do what you said in the video and it work peace

worked like a charm !!! :D i want to make some points though. 1. don't do that on the screen it self ! it will make your screen color turn into black ! but it will cool down and get back to its first state so no worries if it did happened ! 2. focus on the top at most even make it all over the phone just to warm it up. 3. you don't have to make the temperature meter appear, its enough to warm it up for 2 minutes without that message appears and just turn it off and turn it back on ! 4. use something to block any explosion that may happened, was sure jam gonna blow the battery after the first minute, so do it safely ! put gloves and cover your eyes just in case lean your hair drier on standing book or any object hard enough to cover you from hurting yourself and focus again as i already said on the top front speaker , NOT the back Battery !! thanks dude for helping !

I just followed your instructions to the letter AND IT WORKED PERFECTLY.. THANKS FOR THE TIP

I truly never expected this to work but it did! So.. thank you for the great video!!

*Before you do this!!!* There is a much easier fix if you haven't tried it. 1. Go into settings and click on reset. In reset page click reset *network settings*. 2. Hold home button and power button at the same time until you see the apple logo 3. After phone reboots turn it off and wait 5 minutes 4. Turn phone back on and wifi will be fixed and not grayed out I would definitely try this before you resort to cooking it with a hair dryer. Which i must admit i did try XD -Hope this helps everyone it can

My wife's phone has had this problem for a long time, this worked a treat. Thank you so much. One thing to note, watch out for any screen cover and don't let the hairdryer get too hot next to it. It temporarily made that corner of the screen go black.

Was really skeptical about doing this, purposely overheating my phone with a hair dryer...but it worked! My phone got so hot the metal was burning my fingers before it said it had overheated, so turned it off at that point and put it in the fridge, 20mins later and it worked perfectly. No regrets, and an easier fix than sending it off to be repaired! Always back your phone up first, just to be safe!

When I saw this video I thought you were crazy! I tried it anyway because I had nothing to lose and to my surprise it worked! Thanks for the tip. I didn’t get the temperature gage but when I got warm I shut it down and it worked fine.

I just tried it on my iPhone 4s and it worked!!! Thank you

A bizarre coincidence is that this wi-fi problem mostly occurs on White iPhone 4S

This really works! I was scared to try it at first especially when my screen started turning black in the corners but I decided to keep trying it anyway! When I turned my phone back on after being in the fridge I shut off my wifi and turned it back on and it connected again, along with my Bluetooth!

Thank you so much for posting this video, fixed the problem in a matter of minutes!

Thank you SO MUCH!!!!!! IT WORKED, to be honest, when I first watched this video I thought it was a bit sketchy, so I asked my sister (who majors in technology) and she said she was not sure if this was going to work and that i should try a few safer methods, and if they don't work, just try this one because my phone is like 4 1/2 years old, and was used when I bought it, and I could just buy a new one if it breaks, I tried ALL OF THE OTHER METHODS DO NOT WORK!!!! I TRIED ALL OF THEM!!!! Then I just said YOLO and did this method, and I was surprised to say that it worked! Thank you so much, and I would also like to thank the other commenters (you guys gave me the motivation to actually try this method)

This video could have been shorter if you just got to the frickin point

This worked perfectly for me! Thanks a ton. Dunno from where you got this idea, but I have saved a lot of money to get this repaired. Hair dryers generate -ve ions. So, it might be doing something to the wifi internal transmitter.

It worked! Thank you! My cousin found this out for me. I was a bit skeptical in doing this as most things I have tried they didn't work. Glad I gave it a go.

Hey man, i tried this maybe three times and all I've gotten is a crack on my front screen. i MAY be doing something wrong, but i don't see what.. do u think u can help?

GUYS STOP THE HATE!!! I have seen this Method Before, sometimes it doesnt work. The problem is that your phone might have an Overheated WiFi card, Like an Inaccessible SIM card. It may damage your phone though.

Thank you for posting this, been going out my mind the past few days! Will it do it again or should it be fine now?

Thank You!!! I just went directly to putting mines in the fridge!!

Okay so I just did this on MY IPHONE 4S, I heated it up with the hair dryer for 12 minutes (until the iPhone said it was too hot) and then I turned it off, after that I placed it in the refrigerator for about 4 minutes and when it was cool (cool, not cold) I turned it on and the wifi turned on just fine except that the wifi bars don't appear but I do get the signal and I do have Internet, I don't really know why I don't get the wifi bars but I don't really care about that as long as I do have Internet. I definitely recommend you to do this, I looked like a fool heating up my phone and then putting it in the fridge but it totally worked!!! PS if you are going to use a hair dryer don't point it directly at the screen, move it up and down or from left to right so it won't damage de screen or anything from the hardware. Black spots on the screen could appear if you don't move the dryer p.

Weird, after i do this it works for 2 minutes but when i try to tap conect to anny wifi then it not work. I go out of settings and in again and then wifi was turned off :(

Sounded sketchy at first, but having tried everything else I could think of with no luck, I gave it a whirl. Actually friggin' worked! Thanks for the vid!

I tried all the different ways but the hair dryer & fridge is the only one that worked. Thank you for your great video

Wow bro thank you, I just got this iphone for graduation and i couldnt get wifi, i had a waranty so i was gonna get a new one but i tried this and it worked, thank you so much man you don't know how much i'm happy. You did something good for me so i hope someone in the world returns the favor to you!!

Hi, just thought I would share my experience. (FIXED) Got a 4S second hand, and wifi was greyed out. The Apple support suggestions did nothing (no surprises) but I wasn't prepared to heat/freeze it just yet. I did the reset/restore by holding on/off and home on startup then releasing on/off when you see the apple logo. Plugged it into my computer and did the restore (about 30mins) then iTunes asked if I wanted to update it to 8.something so I did the software update. It still did not work, so I turned Aeroplane mode ON, then did the "Reset Network Settings". When it came back on, the wifi was turned on, and it brought up all local wifi networks. I am not sure what made it work, but now that it does I am happy! I have since turned it on and off, and done another reset of the network settings just to test it, and it is still working.

AMAZING!!!!!!! It just worked for me too!!!! I have to say the hairdryer part wasn't working for me as it was taking too long and the upper screen started to waver, so I left it in the sun for 5 minutes then followed the rest of your directions, and BAM - it worked.

Legend mate! Worked a treat. Was a bit hesitant at first but saw the comments as well and thought I'd give it ago. Cheers mate

I had the grayed wifi and no Bluetooth issue and found permanent fix, its based on heating but required removing back cover. Already try it on iphone 4s and iphone 4. I would make a tutorial on how to do it at home without any special equipment just dont know if any one still need it?

for those that doesnt want him to bla bla bla all the time for no reason with 0 context ... go to 2:30 .. you're welcome

Thrilled! I did not even use a hairdryer as I could feel the phone was hot! Thanks a million!

I've just tried this and it worked perfectly thank you so much

It’s wrong don’t trying please It’s working perfect 👌 👇🏻 Apple Official Resolution: Wi-Fi settings greyed out or dim If this occurs, you will not be able to turn Wi-Fi on. Follow these steps to resolve the issue: Verify that airplane mode is off by tapping Settings > Airplane Mode. Reset the network settings by tapping Settings > General > Reset > Reset Network Settings

the problem is still going back

First able, thank you for your video. It helped to resolve the greyed out wifi button issue I've been having for months. Even though your "heat" method alone did not work but after restarting, I clicked on reset all networks; which I had tried numerous times before but never worked. So the credit is all yours!!! Secondly, ignore all the haters and keep up all the good work. Thanks again :-)

Worked for me, incredible ! Didn't go up to the heat warning thing because my screen top corners started to black out so I stopped, but still proceeded with the fridge thing and when I switched my phone back on, it was fully functional. Still ordered a reimplacement wifi antenna to fix the issue if it happens to occur again. Thanks anyway for this tutorial, had heard about it but seeing it helped me dare doing it.

It's the new marketing policy of Apple they make you buy new iPhones. I've got iPhone5s. My Phone was working perfectly, when iPhone 7 was released my phone started to have lots of issues, including the WIFI issue!!!

Didn't work

absolute genius just tried this and it works! give this man a medal!

So I honestly saw this video and got scared thinking I would mess up my phone, however it actually worked! thank you so much for this video.

I tried it and it worked! connected it and everything, but the WiFi greys out again after 5 mins or so >.

I did this but I think I damaged my phones battery life, it dies randomly now, it just died at 70% help

Hey, this worked like a charm. Thanks dude!

This is amazing. At first I thought its a hoax, but it actually worked for my phone. Thanks a lot!

You don't have to get it that hot. Heat it (near the headphone jack) with the wifi settings open and at a certain point you'll see it detect networks. At this point do a hard reset (home n power buttons together). Your problem will be solved. You don't need to freeze it. I think overheating the phone risks causing damage to solder joints.

i did this and it still didnt work. I repeated it like 6 times

I tried absolutely everything to fix this ridiculously irritating problem; resetting the phone, forgetting networks, etc. I was going to use factory reset, but thought I'd give this a go first. I was really concerned about any possible damage but, really, what use is an iPhone without Wi-Fi anyway?! It worked and I'm actually shocked it did! I do wonder how this actually works, but considering how hot my phone was after using the hair dryer on it, I'm not sure I'd want to know! One thing I will say, though, is that the phone gets so damn hot it's difficult to hold it and switch it off! Thank you for an awesome fix to what had become the bane of my life the past 24 hours!

this works surprisingly well. You don't have to take the phone apart to fix it. When using the hair dryer I just had to hold it over the speaker for 3-5 minutes, never got the too hot message but it was hot so I shut it down and put in the fridge for 5 minutes and it works. This might work because it helps the solder joints for the chipset to get resoldered. Use to do same thing for old pcb board but with a oven waaaay back in the day. The screen does go black due to the heat but it does return to normal, just don't go crazy. Thank you fore the video.

is this a temporary fix?

Another thing that worked for me is if you turn do not disturb and airplane mode ON then turn the phone off for 5-10 minutes then turn it back on

Hi, thanks for the tip on WiFi with the 4s, got to fit a new battery charger connector before I try your tip!! Thanks Again 😉

Thanks a lot man!! at the beginning I thought that was a ridiculous thing but finally it works...

this doesn't work longterm

i would dance at ur wedding tank I soooo much

This actually really works 😉 Thank you so much for sharing this 💕 I already fixed the phone of my mother

I bought an iPhone 4s that had this problem and the first time I did this trick it didn't work but the second time it worked like a charm.

Quick Tip: Turn the phone around so the screen is facing downwards and heat the back of the phone, this will prevent the screen from potentially being damaged from excessive heat. constantly move the hairdryer around to avoid staying in one continuous spot. This method will heat the phone up quicker as the logic board sits on the back cover. You do not need to put it in the fridge just allow the phone to cool down in a natural environment. This method works however the "grey out" may occur again after some usage of the device requiring you to perform these steps again. Ideally the WIFI Chip on the logic board requires a solder reflow for a permanent solution.

You son of a bitch! you owe me momey. i burned my phones screen!

Thank you so much for sharing this video! This really works! I was skeptical at first, but i thought there was no harm in trying anyway as the phone was really old. Took more than 5 minutes for the too hot icon to appear. Then 10 minutes in fridge. Turned it on and it worked right away. Cool!

That's brilliant! Thank you for sharing.. THIS WORKS

Thanks, it works like charm, almost cried when the screen turned half black during the hair drying process

So I was slightly skeptical when I was watching this. But I tried it and it ACTUALLY works. Thank you for this. Cost me far less than to actually have someone fix it

I am SO grateful! I just tried it and this WORKS!!! Thank you for sharing this with everyone! :)

Det fungerade tack för tipset...thanks for the help it worked :)

I am a travel blogger, my wifi died suddenly, I took it to the apple store and they told me I needed a new phone. I use my phone for wifi only, not any cell service. I came home and tried this. I held that hair dryer on the phone for 25 minutes! Finally I got the temp error. I threw the phone in a freezer bag and left it in the freezer for an hour. When I turned the phone back on I had WIFI. I have clue how this works, but damn glad it did. Ill report back to see if this "fix" lasts! Amazing! Congrats to you my man! Thanks from Jays Odyssey for saving me from buying a whole new phone! To the negative ninnys go f#$% yourself UNTIL you try it for your self!

OMG, I have the greyed off Wi-Fi button. Did exactly Hypertux suggested in the video. Hairdryer to heat up my iphone 4s (the over heating message did not come on) until it is quite hot to touch, switch off the phone and then in the freezer for ten minutes. Took it out of freezer, turn the phone on and I can't believe it, the Wi-Fi button can now be switched on and off! Hypertux, you have saved me a lot of aggravations and expense. Thank you, Thank you!

You are a wonderful human being! Thank you so very much for sharing your solution. This is, without a doubt, a contribution. Thanks, thanks, and Thanks.

You are a legend, this fix actually works! Thanks Bro

This is amazing! I tried this and it really worked!

Very straightforward and simple.

That is awesome. After rebooting, resetting, updating iTunes and trying all the technical advice I thought I've got nothing to lose, give it a go. It worked like a charm. Thank You. How do people work this stuff out?? Maybe next time my car breaks down I'll get try to get access to a commercial heater and a fridge and give it a go!!

My dad and I were shocked when this is the simple answer to that issue.

Worked a dream. Thank you for sharing 😊

Good Tip! Worked! Thanks. Updated to ios9 and the wifi and bluetooth bombed out. Heated it up and allowed it to cool naturally and it worked.

I am absolutely dumbstruck... I have been pulling my hair out due to this issue and after watching your video this morning I did it and it worked... i have no words... thanks a lot...

Dude! You are awesome this video totally fixed my phone! Thanks! You saved me the trip of going to the Apple Store.

Wow! Incredibly helpful, It totally worked! Thank you MILLIONS!

Worked!!! Thank you so much! I did get some black spots showing up on the screen at one point (there was no heat warning for me) but I stopped immediately and there were no lasting effects. Just a warning! Stop as soon as you see spots, even if there is no heat warning! But thank you, I know it wasn't your fault it happened. The fix worked in the end anyway!

Thank you so much this helped me.... (: I hope you to share more about I phone

Worked for me, many thanks. Tried all other ways to sort it (including Apple's official suggestion to 'reset network settings', which didn't work!). I'm so pleased. Thanks again.

Thank you it worked. Amazing. 👏

I tried this and it worked!! The only thing is that my iPhone 4 was getting really hot from the hair dryer and the warning never came on so I just turned it off and followed the rest of the steps. After 10 minutes in the fridge, my issues were resolved! Thanks for this video! :)

It worked!!! Thanks! I thought I would have to take it to the iPod repair places

I am having the same problem with my iPhone right now and hopefully it helps. Thanks!

cheers bro your a huge help it works now your a pure g

You're a genius man! How did you come up with this solution?

wow! this video really freaked me out! thanks for this! My 4s just suddenly can't connect to wifi today. I wanna try it but i am still not sure, am afraid the hot and cold thing might bring moist inside the phone.

again, i am so so thankful for you
