Suffering from the same issue, using Nuki 4.0 Pro.
TP-Link Deco as well
You might also contact TP-Link, last time I did it I was not lucky because hard to know when connection becomes less stable but if we are a lot to contact them and also ask for the ability to change DTIM we can hop they will do something.
I also hop one day a setting implemented in the Nuki smart lock 4 pro will be implemented, within setting level to high but nothing is sure and I don’t know if it finally works for people who have been able to test it.
Hallo, I’m having similar issues with my Nuki 3.0 Pro. I’m losing Wifi connection from time to time. Since I use the Nuki to unlock a holiday apartment, this is really annoying because my guests can’t get into the apartment (I’m using MQTT via Wifi to unlock).
Reading all the discussion here, it seams the best for me is to use a Nuki Bridge and disable Wifi on my Nuki 3.0 pro. Then all communication with the Nuki runs via Bluetooth, and the bridge is constantly powered, so no issues with power saving on Wifi. This should be a reliable, stable solution, right ?
@Jürgen: is this correct ? I assume the Nuki Bridge supports MQTT ?
Thanks and regards
Konrad
I have the same issue, but for me the issues started after updating to firmware 3.9.5, before that it worked perfectly fine. I’m also using Ubiquiti Unifi accesspoints. I’ve tried all suggestions in this thread, but none of them helped. I’ve now connected my Nuki Pro 3.0 to an old Nuki Bridge I had laying around and the Internet connection is stable again, but of course this is not how it should be.
Thanks, Frank, for sharing your experience.
Can you help me with this: I checked the Nuki Bridge documentation in more detail and i understood that it does not support MQTT. It can be interfaced via an HTTP-API. Is this correct ? Does this work without an active Internet connection (to Nuki Server) ? I dont want to rely on Internet or any Nuki Server.
thanks and regards, Konrad
Sorry, I don’t have any experience with that.

It does not support MQTT.
There is a local http API for the Nuki bridge.
I am not sure if it requires the bridge to be connected to the web but the API itself is local communication.
I have had two Nuki 2s running for years, I have had some problems with the API, but they work.
I have installed a nuki 4 and I have had to go several times to restart it with the resulting problem with the guests, now I am trying to return the lock and I do not have a support solution
I have the same problem since the update to 3.9.5 unfortunately. One of my Nuki locks is in another country & I’m not able to connect to it, this is very annoying and frustrating!
Can Nuki support do anything about it?
I confirm my Nuki Pro 3 is working fine after install beta firmware 3.10.1 and set battery to Medium
Unifi report it 100% ok now
My device updated to 3.10.2 and it look like wifi stability has worsen respect 3.10.1
What was changed? i suggest to go back at how it was in 3.10.1 as was stable and Unify reported 100%
Hi.
I have a 3.0 Pro. Since the update it get to the lastets oficial firmware, things beceme a mess. Lossing conecction constantly. Tried the betta. 3.10.1 was more or less fine (problems, but better than latest offical). I left the autoupdate active, and it went to 3.10.2. An horror again… Then update to 3.10.3. It looked promissing, but now after a few days, and with inactivity in the door (not being opened/close) it’s back to not working again basically
It’s connectig to the WIFI for about 30s-1minute in 1 hour intervals.
No way to take it back to the stable release previous to actual one with the problem.

By the way. If you restar the lock with 3.10.3 (remove bateries and then set it back after some seconds), it works ok for a while (no problem with connectivity). I would say around 24h, but now sure about how long.
They restarted it for me (we have it in another place, not home) more than 1h ago, and has been connected since then with no drop.
It was up for about 1 hour. Then it start to have intervals with no connection (disconnecting and reconnecting) of 2-5min. Intervals become bigger and end with 1 hours between the. So frustrating. A way to reinstall and old version is really be needed.
Hello everyone!
Everything has been working fine until I updated 2 months ago to 3.9.5. Since then, I am getting my device in offline status in about 50% of the time when I want to use it. My nuki is very close to the router and there haven’t been changes at home regarding the internet network and the devides I have connected to it. With all the information there is available here, it’s impossible to know exactly if there is any solution to solve the issue. Could anyone help me? It’s awful this behavior as now I always need my keys to open the door

I have the exact same problem as above.
My setup worked for ~2 years, but 2 out of 3 Nukis have been having issues for the past two months.
There also seem to be issued with Time synchronization because even my scheduled lock at night time is happening randomly during the evening.

Same issues for me.
I purchased a Deco XE75 kit, to improve network connection on my nuki, but it worse than my previous AP.
For the price we pay this item, such issues are not acceptable !
