iPhone X wifi issues

I went to the Genius Bar at the Apple store and thank goodness I got an employee who knew his stuff! I let him know about the whole issue I was having with my WIFI at home and how I was trying the WIFI at the apple store and I was not having any issues like I have at home.

The first thing he asked me was what kind of router I had (I have Uverse Internet so ATT provided me with their router), he said there are two WIFI frequencies you router broadcasts and did I know which one I was connected to? I said I have no clue, I just sign in to my WIFI network name and put in the password.

He said your router has two WIFI frequencies, one is 2.4 GHz and 5 GHz. The iPhone X is the first iPhone that has to use 5GHz frequency (if it uses the 2.4 GHz frequency, it will work but cause it to drop, but the phone stays connected to that radio frequency). He ran a diagnostic on my iPhone and said my phone is fine. He asked if my WIFI network name was the same or different name regarding 2.4GHz and 5GHz. I checked my router's info, and it has the same name. He said I would have to name the 5 GHz different from the 2.4 GHz cause my iPhone connects to the first available network (2.4 GHz - since both frequencies were named the same thing, I couldn't tell which one it was connecting to). I renamed my 5 GHz and up until this point, everything is working fine and have had no WIFI dropping issue with my iPhone!

I told them that guy who helped me out deserves a **** bonus!!! I hope you guys understood what I am saying, if not let me know, I will try to explain it better.

But this should RESOLVE the issues we are experiencing with WIF dropping.

I went to the Apple Store with my phone. The MRI test indicated my phone had problems with the bluetooth chip which caused the wifi to fail at times. Got the phone swapped immediately. I recommend everyone to visit the Apple Store because the service is very good, however the iPhone X is a pain the ***.

The iPhone was bought on 10 july, I went on 12 july to the Apple Store because people could not hear me during calls => I got a new phone. This phone had problems with wifi connectivity => 13 july I went back to the Apple Store and got the phone swapped again.

3 days gone since my purchase and already on my third phone... says a lot or is it just bad luck

Dare to say PROBLEM SOLVED. Today was one of the worst days that I could not enable wifi at all. Even turning cellular data off had no effect. I was about to restart the phone but just before that I tried the Console thing. Connect the iphone to my macbook and opened Console app. Select iphone on the sidebar and then above the window with the messages select ->Errors and Faults. There were messages like wifi browser starting/stoping preferences messages etc. One thing that caught my eye was ever repeating messages of an application that was not even running! The application in blame was that otherwise useful application called "Wifi Map Pro" (The paid version). I went to the preferences and exluded the app from the background updates. Even started and stoped the app. Messages of errors from the app still repeating.

Finally I removed the app from the phone. No restart performed. The phone does not experience wifi dropping anymore. The Preferences app is not crashing. To make the long story short, everything works so far! My iphone X is back from the sickbay!

Morale: It maybe a third party app issue. It maybe a different app for you. Give it a try!

Thaks for this, i was going out my mind. Apple told me to restore and said nothing was wrong with my phone which was the truth but didnt mention the 2.4 or 5 ghz thing. This only started happening when my router was replaced. Ive now renamed my 5ghz channel and now 2 networks have appeared problem solved.

Problem solved. I restored the iphone as new (not from backup!) and now the wifi works properly well. At genius they told me that sometimes the backup file has some errors that could cause this problem.

Paris523 You are an angel sent straight from the heavens!!

I have had this issue plague me for the last 2 years- towards the end of my iPhone 6's life and transfer over to my iPhone X. I knew it was a software issue as I went through the various steps other people have mentioned in this thread and that apple support recommend trying such as resetting network settings, reseting the iPhone and backing up and starting as a new iPhone. Setting the phone up from new seemed to work for a few days and then when i restored my back up the issue came straight back. So everything pointed toward the software.

I had no idea about "console" on mac never mind for the iPhone, however this didn't help me as it didn't show any errors with the names of apps that might be causing the issue, but as Lawrence Finch pointed out it may be a wifi monitoring app so i tried deleting my "Speedtest" app by "Ookla" and Voila!! All seems to be completely fixed!!

To completely solve the problem I did have to reset network settings and restart the phone after I had deleted this app, but all seems to be working completely normally again after much testing.

Thank you so much for sharing this information here and for all the extremely detailed and informative comments from everyone else. Very thankful this is finally fixed, but slightly disappointed such a small silly thing like a speed test app can cause such frustration on such an extremely expensive and sophisticated device!

I hope everyone else finds a solution to their problems.

Thanks again Paris!

Make a genius bar appointment to have your phone checked out. This is usually a hardware problem. Genius Bar Reservation and Apple Support Options - Apple

It has to do with apps, I had the exact same problem with the new iphone X I got. I went through all of my apps and deleted everything I didn’t use frequently. And now the phone is working normal again. I don’t know which app/combination of apps was causing it, I wasn’t patient enough to test my wifi after every app deletion

That means something is corrupted in your backup. You can try restoring your backup, then go to Settings/General/Reset - Reset Network Settings. If that does not fix the problem whatever the problem is in your backup can't be fixed. You will have to restore iOS and set up the phone as New, then restore your apps and other content.

One possibility - do you have any apps for managing Wi-Fi connections, or monitoring Wi-Fi activity? If you do it may be causing this problem. At least one other person in this thread found that by deleting an Wi-Fi monitoring app it fixed the problem. The specific app they found that caused the problem was Wifi Map Pro.

I would personally try to delete all the apps that you don’t use often, if you don’t restore your backup then you’re giving up a lot... I had the issue that wifi suddenly deactivated and that I couldn’t turn it on again (I pressed but it immediately deactivated), sometimes after 12 times pressing furiously it stayed on. I also often had the issue that wifi was active and that it showed connected to the wifi network in the wifi settings but that the 3g/4g icon was showing at the top. Then apple support did a remote scan and said that wifi chip was inactive and they sent me a new phone. I never had a totally unresponsive black screen but I often had that my screen would take 10 to 30 second before it went from black to alive after pressing a button, just because it was freezing. Now it is totally fine and it’s a pleasure to work with again.

This is so not apple to happen. But I recently also had my imac crash and was not able to reinstall mac os x on my fusion drive (I had to partition and install on second partition, something I figured out after reading all over the internet and reinstalling 10 times). And then my wife her space key on her macbook stopped working, she brought it in and after repairing the space bar issue her wifi is broken. It’s really heartbreaking, I didn’t have a single issue with apple hardware for the last 8 years and I have the feeling that it’s not only back luck but a decrease in quality that is causing all the issues now... I hope I’m wrong, as I love the company.

Okay, so I went to the Apple store this past Wednesday and I explained the issue to the tech that was assigned. He also reviewed the notes on my account (which you have a summary of in bullet points as per my last post). The tech - as frustrated as I - offered to just give me another new replacement iPhone X. If you've been following my posts, you will see that this is now my 3rd iPhone X replacement. The tech said that if the issue shows up again in this 3rd replacement unit then I should just call Apple Support and he put instructions in the notes on my account to have the support representative escalate the issue to the engineering team.

So I get home from the Apple store and play around with the new device. Everything was fine. Next day, the issue appeared again! ...sigh.

So here are my thoughts to this point and how I plan to proceed:

It is crystal clear to me that the problem exists either solely in the hardware itself (on some units and not on others) or it is a bug in iOS 11 that manifests itself only on iPhone X hardware... and in my technical opinion, it's most probably the latter. I've tentatively come to that conclusion because both the iPhone 5s and the iPhone 6 Plus that run daily on my home network are running iOS 11 and they absolutely never, ever drop WiFi. Not once! Not ever! And they are used with generally the same frequency as my iPhone X by their owners. Not to mention there are 2 iPads, 2 Android tablets,, a Macbook Air and a Macbook Pro along with quite a few other WiFi devices running on my network regularly which absolutely never ever drop WiFi. So why does ONLY my iPhone X have this WiFi dropping issue? For right now, I am hypothesising that it's some issue with iOS particularly on the iPhone X. So what I'm going to do before I call Apple support and have the issue escalated, is I am going to take a leap of faith and install iOS 12 beta on my iPhone X and see if that makes a difference. I've scoured the internet and found that iOS 12 beta is remarkably stable - in fact, it seems by consensus to be the most stable iOS beta ever, especially in it's early stages. In fact, I told the Apple tech that worked on my case at the Apple store that I might consider installing iOS 12 if the issue appeared again and he went on to tell me that he is running iOS 12 on his iPhone X and that it is outstanding in terms of stability and he thought it was a good troubleshooting step to take if the issue appeared again. I can always go back to iOS 11 if things get sketchy. At the moment, there are about 15 very well documented bugs in the current iOS 12 beta and 3 of them will be more of an inconvenience than I care to take on right now. So I will wait for the next beta revision to see if they've cleaned at least those 3 up.

As usual, I will update you all as soon as there is something to tell!

I liaised with apple support, they ran a check and my wifi chip failed it so now they've sent me a new phone. Hopefully more success this time!

I've had the same exact problem and it drove me mad. I changed network settings, restored from back up etc. and eventually got it changed for a new one at the Apple Store last Friday. It just finished restoring from the iCloud back up and seems to be a bit better but its early days. Yesterday it was kept freezing when I was using wifi and then went straight to the web page as soon as I turned it off. This is what kept happening with the old phone. I am not impressed - especially given how much this phone cost. I have had most of the iPhones and did not have this problem on my iPhone 7 plus. My daughter did not upgrade her phone this year and kept last year's iPhone 7 plus but has kept up to date with the iOS updates. Strangely she has not had this problem so maybe its the phone.

After hours of frustration, I reset my modem and router by unplugging them and plugging them back in after a minute. It seems to be working now. (keeping fingers crossed) I think the router was confused by both phones... new and old ones.
