I noticed last night that i had a firmware upgrade pending on the Deco app. I completed the upgrade successfully, but have been plagued by issues ever since.

 

I have a P9 connected to my ISP router in my hallway. I then have another P9 in a garden office that is connected using backhaul (as Wifi is out of reach). I then have three M5s  that are around the house. The mesh network is set up as "Wireless Router" and wifi on my ISP router is disabled. Until yesterday, everything ran smoothly with no issues.

 

Now, when the devices work fine, all is well. But frequently (multiple times an hour), they seem to lose connection completely. Internet is broken, pages don't load on browsers, videos pause, games don't work. This can last anywhere from seconds to minutes. 

 

I'm not particularly network savvy, but when I check out tplinkdeco.net the only consistent thing I can see is that in the periods of outage, CPU usage shows as 100%. I don't understand enough about the log files to know what is causing this, but it only occurred after the recent firmware upgrade. I've tried rebooting the network and the ISP router multiple times to no avail. I've also tried deleting the network, recreating it and adding every TP Link device back one by one, again to no avail.

 

The Deco app is very up and down - i can use it for a few minutes, then it tells me there's no network anymore, then it's back, then it's down etc. Most of the options in the app don't work and I get an error saying changes can't be saved or to access app via my deco wifi to make changes (which I'm doing). The tplinkdeco.net site is even worse - very intermittent in terms of whether I can even get in or not. Often I get a spinny wheel upon log in and I can't get any further.

 

All devices:

 - Main P9 - 1.2.1 Build 20240716 Rel 60900 firmware

 - Living Room M5 - 1.7.8 Build 20240719 Rel 70981 firmware

 - Main Bedroom M5 - 1.7.8 Build 20240719 Rel 70981 firmware

 - Garden Office P9 - 1.2.1 Build 20240716 Rel 60900 firmware

 - Spare Bedroom M5 - 1.7.8 build 20240719 Rel 70981 firmware

 

Examples of repeated log messages (no idea what they mean):
