iPhone keeps forgetting my wifi network

Move the Wi-Fi to 5 GHz (only), and see if that works better.

Hi there!

There is a few possible things that could be causing this. if you could please upload a picture of your router that would be nice. Also, you may be using a multi AP system that is improperly configured which may cause the iPhone to try and grab a different SSID. Also restart the device. Another thing it may be is that the wifi network is going out which may sometimes cause the iPhone to refuse to grab that signal.

Hope that helps,

Adin

You have asked your question really well and supplied excellent supporting documentation (screenshots).

If that happened to me, here’s what I would check:

Based on this comment shown in your screenshot:

”You can also access this Wi-Fi network by bringing your iPhone near any iPhone, iPad, or Mac which has connected to this network and has you in their contacts.”

I would check Settings > Contacts > My Info and be certain it’s set correctly.

Go to Settings/Cellular and scroll to the bottom. Turn off Wi-Fi Assist. This feature switches to cellular when the cellular signal is better than your Wi-Fi signal. As 5Guc is faster than most Wi-Fi networks (mine clocks at over 500 mbps) this might be your issue.

Lawrence,

Do you think it would still prioritize 1 bar of 5G over a wifi network?

Thanks,

Adin

If the 5G is faster than your Wi-Fi, yes.

But turning it off to test doesn’t hurt.

Something else just occurred to me, based on another thread I responded in. Do you share an Apple ID with anyone else, who might have switched to a different network?

I have used Wifi assist for years. the fact is the SSID Password is not available under information for the wifi network (should show under the Auto-Join switch). Even if the iphone "grabbed" a better connection, it should NOT EVER delete the password. I have passwords to wifi accounts I used months ago (and not since). Phone has grabbed both cell and wifi accounts since then but passwords exist. Something is going on in 16.4.1 causing the password not to be retained

I’ve never had an occasion where my phone deleted passwords, unless the password was deleted from another device that shares an Apple ID with an iPhone; Wi-Fi passwords sync between devices that share an iCloud account. I also haven’t seen you in this thread before, so it would be helpful if you would tell us what model iPhone you have and what iOS version.

If you have iOS 16 you can see the Wi-Fi password by tapping on the obfuscated password dots.

ios 16.4.1(a) 12 mini

Your last sentence is the very problem, as I discovered today. Unlike the normal display you would see with the obfuscated password dots - that line DOES NOT EXIST on my problem network (it does exist for the other two networks I have used on this phone). It should appear after the Auto-Join switch and before the Low Data Mode switch.

Also having this same issue, both my iPhone & Mac have 'forgotten' my wifi passwords three times this week. And it's not just my home router that is forgotten.

Same problem, has been happening for about 1 month. Iphone 13 mini, IOS16.5. Macbook pro, IOS 10.15.7. It happens to multiple wifi networks at different locations which I frequent. Some homes, some restaurants. It doesn't happen everytime I leave and return but sometimes it happens even while I'm still there. Manually joining the network and adding the password works fine.

@apple: this is obviously not a problem w/ the various wifi networks. Once manually joined w/ the password everything works fine for a while. These wifi networks have all worked w/ out issue for years. They are managed by different entities (some me, some others) and other people I know who frequent some of the same areas don't have the same issues. Both iphone and macbook share the same icloud id and I have my keychain passwords saved there. I have tried removing the keychain entry when connected to the wifi network and that doesn't resolve the issue. When I am disconnected from a wifi network which I have previously used and w/ in range, the keychain entry for that network doesn't exist, so clearly this is an issue w/ the keychain entry being removed from the icloud keychain data. Obviously this similar problem is affecting other users so please take it seriously and put some effort into resolving it. If you contact me, I can provide detailed info and assist troubleshooting.

I am having the same issue

I believe it has nothing to do with the latest ios update because I am having the same problem with my macos Catalina

Ironically, I have my apple id installed also on iPad 8th and this never occurred

I think this problem started only after I installed my ID on the new iphobe 14plus

Before it was ok when I was using mac and iPad

Hoping these will make someone connect the dots

I updated to iOS 16.5.1 the other night and since then, my Wifi password has remained intact (finger crossed this continues).
