Model: Deco S7  
Hardware Version: V1
Firmware Version: 1.5.0

Problem arising after recent firmware update. 1.5.0 Build 20240329 Rel. 61026.

I have TP-Link Deco S7 AC1900 pack of three S7(1.0). Almost every morning (midnight to 4am) the Main unit loses internet connection and devices cannot connect to the Main unit even though the WiFi name is visible (I use an iPad for testing).

My usual set up is: Virgin Media Super Hub 3 in modem mode with 250 Mbps BB. I get between 250 Mbps and 290 Mbps on my phone using speedtest app. Usual Operation Mode WiFi Router, fast Roaming disabled  and Beamforming enabled. LED Control set to off but now switched on ready for next time.

I have also tried using the Deco as an Access Point but it is just the same. I have just set the Deco and the Superhub as two separate networks so I don’t lose the WiFI overnight (the Superhub is used as the main network and the Deco WiFi is just for testing and for my Sky stream TV box).

I have factory reset all three Decos and swapped the Main unit for what was a satellite unit and which is now the Main unit. Still fails overnight.

Deco S7s are as they came out the box, except for the settings to get them connected. Nothing else on the Network except the usual clients.

I see older versions of firmware are available for download but the release notes for the latest says no going back?

Hi, Thanks for the feedback.

I noticed you mentioned the disconnection always started at a specific time which reminds me of a similar post a few days ago also with the VM hub: https://community.tp-link.com/en/home/forum/topic/670928. But Hub 3 doesn't have a 2.5Ghz port so it might not be completely the same.

So I hope you can keep VM Hub 3 in the default router mode, and also set Deco S7 in wireless router mode to see whether it maintains a stable connection.

(you could disable the WiFi on VM Hub 3 and use the Mesh WiFi on Deco S7 only.)

 

As for the firmware downgrade, it could be implemented via firmware recovery here:

How to use firmware recovery on Deco

Moreover, since 1.5.0 was released a few weeks ago, I wish you could test the first suggestion first for some time before downgrading the firmware.

Wait for your reply and best regards.

So current setup is VM Super Hub 3 in wireless router mode and Deco S7 in wireless router mode with different network names. Most devices (30+) connected to the Hub 3 and the Sky Stream box connected wirelessly to the Deco (the Sky Stream is the reason I bought the Deco in the first place). That worked fine overnight so I plan to keep it like that for a week or so and then try some changes from a stable starting point.

I don’t want to do the firmware downgrade but it’s good to know I can. If I do would I need to do all three Decos or just the one that’s connected to the Hub 3?

Thanks for the info yes.

  @Tim_7 I am having the exact same issue. Since updating to 1.5.0 Build 20240329 Rel. 61026 on my TP-Link Deco S7 AC1900 pack of three S7(1.0). Mine spaz out and go offline at random times of the day. Sometimes the secondary deco units appear offline even though the light is white. Sometimes they are all online but all my devices disconnect. 
 

is there a way I can roll back the firmware or get a refund?

Ive only had them since August 2023. I might just buy a new set and send these back as those for a refund and keep the new ones on older firmwa

Hi, You need to downgrade all three Deco S7s. But as I mentioned earlier, the issue might not be related to 1.5.0, so you could download the main S7 that’s connected to the Hub 3, then make sure the old firmware 1.4.1 works great, then download the other two satellite S7s.

Thank you very much.

Hi, you could refer to the suggestions here to roll back the firmware:

 

As for the firmware downgrade, it could be implemented via firmware recovery here:

How to use firmware recovery on Deco

 

Moreover,  I have documented the recent feedback on version 1.5.0, and none of the reported issues have been confirmed to be related to the firmware upgrade. Some users fixed the issue by resetting and reconfiguring the Deco, others by restarting the whole Mesh system. One user disabled the IPV6 to stop the disconnection issue on mobile clients.

 

The new firmware has added many advanced features. Sometimes after the firmware upgrade, it might take time to sync with the current network devices. I do wish you could manually restart the whole Mesh system( also try to retart the ISP modem/hub once if possible) and check again whether the Mesh system would get better.

Thank you very much and wait for your reply.

History: factory reset all three Deco S7 and Virgin Media Hub 3. Deco S7 firmware 1.5.0.

Tested with Hub 3 in modem mode, and in router mode with the S7 in router mode and in access point mode.

All the same result: more or less twice a day the main S7 loses connection with Hub 3 and only recovery path is to power cycle the S7. As well as this, either of the satellites will randomly go offline (when the other S7s are working OK).

Progress: rolled all three back to 1.4.1 and now working perfectly for two days so far. Hub 3 in router mode (wireless off) with the S7 in router mode.

Plan: wait for 1.6 laugh.

I am experiencing issues with this as well

 

My setup is:

PfSense Firewall and Router (provides DHCP, DNS etc) -> Netgear Smart Swtich -> Each Deco connected to the switch, Decos setup in Access Point mode

 

Working on 1.4.5 firmware, no issues at all, complete stability.

 

Upgraded to 1.5.0 and disconnects happen multiple times a day where main deco needs to be rebooted for things to start back up; we're looking at rebooting every 4/5 hours and always in the morning. Devices connected to the satellite decos, via ethernet, work fine even though they're flashing red, though the web console for satellite decos does not respond (no logs). WiFi devices though (smart cameras, laptops and phones) will sense they have a WiFi connection but will stop working until their individual WiFis are turned off and back on.

 

The deco app begins to load and then says it cannot communicate with deco network. On the off chance that the app does load, it'll show 1 or both of the satellite decos as offline, then say it cannot communicate with the deco network.

 

As some suggested resetting all decos and starting fresh, I did try that and I thought it worked but a few hours later, the issues all came flooding back. 

 

Followed the guide to downgrade the firmware back to 1.4.5 and it's been over 24 hours with no issues, all devices have remained connected and no network loss issues.

Sounds very very similar to my experience. My kit has been running perfectly for a week now on 1.4.1 so I would say there is something wrong with 1.5.0.

Hi, 

I'm, experiencing the same issues as you mentioned. But in an even crazier way. 
My Deco S7 1.20 units are losing connection to the internet 10 - 15 times a day. 
I have one switch that converts the optical internet to RJ-45, the main unit is directly connected to it, and all other Deco units are connected with ethernet cable. 
The only way how to get the internet back up and running is to restart the whole mesh system. Even all of the PCs that are connected from the Deco unit with cable will lose connection. 
As a software developer working full-time from home, this is crazy. Issues with units start after the upgrade to 1.5.0 Build 2024032 Rel. 61026. 
I will give them one more try and do the downgrade manually, which is also annoying because it's blocked from doing the downgrade through WEB UI. 

I will let you know if the downgrade worked and the mesh system is stable or if I sent all Deco S7 for a flying trip through the window. 
But all I can say about this upgrade is that it's not an upgrade but a failure. I've been using the TP-Link system for years and never had issues like this.
