Wi-Fi Wrongly Displaying "Incorrect password"

[PhoneHelperUK]

Hi All.

Bit of a weird one, this.

My phone and an S22 Ultra which are both connected to the same WiFi network, and have both worked for over a year now, are beginning to say "Incorrect password" whenever I connect to the network.

Simply, this is surely because of a mistyped password? Well, it cannot be, as the password has not changed since I put it in, and since it has worked for a year, this has to be the nearest "cover up" message for a more major issue.

No other devices on the WiFi have this problem. There are three other Samsung devices (Note3, A5, S20 FE) and all have no problems. Not a problem with the WiFi itself.

Done the basic things - restarted the phone, removed all known WiFi networks, turned off intelligent features etc etc.

Issue still occurs.

At all costs possible, I would like to avoid performing a factory reset. It's a complicated process and will use up a weekend, which may lead to no fix.

Any advice?

Many thanks!

My A73 is doing the same. All other devices does not have this issue and connects automatically

But when I click on the chosen wi-fi (which is my default home wi-fi then it connects without the error message. The moment I leave my house and come back it has the error message again and I constanly need to connect manually every time I come home. This is very annoying 😑

I'm thinking it may have something to do with a software bug or NIC card issue. Sometimes mine even will say "Connected without internet." This is two different routers with the same issue one an AC and other a WiFi6 router. It's annoying and the only fix is to reboot my phone.

Found the issue. In the wifi settings,  turn off randomized mac address, and change to use phone mac.

I'll try that out too. Didn't think of that but after doing some research it seems to be a known issue. Thanks.

I know it's an old thread.

But it started happening to me a week ago. 2 samsung (s20+ and s23) having the same issues, although  15+ devices already connected without issues, including an old samsung s7.

My S20+ was even able to connect to the guest network correctly but not my main network.

It was driving me crazy.

Hope my answer might help others.

Done that, still saying "incorrect password" and when I click on the wi-fi router, it connects without any hassle 😔

Not sure what's the deal with the new Samsung phones. It's making me lose faith with their devices. Maybe the "Nothing Phone" is the next device for me.

It seems like the issue has been happening since the one 6.0 update for me which was last December, but it could have been a month or two before. It's annoying and makes me question Samsungs quality.
