Samsung Galaxy A53 can't connect to mesh wifi (TP-Link Deco X60)

[Akuher]

Samsung Galaxy A53 is not able to connect to TP-Link Deco X60 mesh wifi. Connecting to the wifi fails most of the time and when it finally succeeds it soon disconnects again. I have tried resetting Galaxy A53 network settings and even hard resetting the phone. Those measures didn't solve the problem. I also got a replacement phone but still the same problem occurs. We have two other Samsung phones and multiple other devices connected to the same mesh wifi without any problems. Galaxy A53 is the only one that fails to connect.

I have tried to solve this problem with TP-Link and they have acknowledged the problem. Unfortunately, they haven't been able to fix it and now they are leaning towards this being Samsung's problem, not theirs. Maybe a problem with latest Exynos chips. You can also find discussion about the problem here:

New Samsung A53 can't connect stable to Wifi on Deco X60, connection keeps dropping - Home Network C...

It seems that the problem is with 5 GHz wifi with safety encrypion enabled. If any kind of safety encryption is enabled on the wifi when 5 GHz is also enabled, A53 is not able to connect to it. As soon as I disable safety encryption, connection becomes stable. Also disabling 5 GHz removes the problem. Sadly, neither of these are a permanent solution to the problem. I also noticed that A53 is able to connect to the mesh wifi's main router. Wifi connection is stable near the main Deco but connection fails as soon as A53 moves nearer one of the two slave Decos.

I really hope Samsung can fix this soon! A few weeks ago I posted about this problem to the US Samsung Community but for some reason that post got deleted without any answer from Samsung. I know this is a wide spread problem as you can see from the TP-Link forum discussion (the link above). Hopefully Samsung isn't trying to wipe this under the rug.

I have the same exact problem. I am living with the mobile living on guest 2.4Ghz network whilst everyone else on the dual band mesh. It appears to be Samsung issue.

I have the same problems on my wife's A53.

I have 35 clients connected to the Deco X60 and none has problems. In tp link forums someone is saying that Samsung is working on a firmware update and will rollout: New Samsung A53 can't connect stable to Wifi on Deco X60, connection keeps dropping - Home Network C...

That is already a long time ago. 

Luckily we have strong customer protections here, i will be returning the phone and buy a S21FE (my wife unfortunately still wants a Samsung)

Yesterday I installed the latest update on my A53. With this update, and change the default value use "Telefon-MAC" instead of "random MAC", the WiFi-connection works. And it looks like it is stable now. I will cross my fingers 🙂

Bad news again, also after installing the newest updates, the wifi-connection is not stable. It was working and It was very fast. But for few minutes only. I still hope, Samsung will fix this issue soon.

Same with me. My A53 received an update this week but this bug was still not solved. Pretty much useless phone without a working wifi.

I got the same problem with my A52s 5g.

Yes, totally rubbish Samsung A53.  I take the phone to customer service.  They always said reset to factory default.

Bought the A53 last monday, after searching, trying a whole week... same problem and temp solved it with a guest network at 2.5 Ghz 😢

My A53 just received One UI 5.1 update and this wifi bug was still not fixed...

Yes, it looks like Samsung is not really working to solve this issue. But in the meantime I read some shouts for help also from Samsung S23 users. Also the new S23 has WiFi-issues. We will see....
