@FireDZ I am getting this in my logs as well every 3 seconds.

@samwardill 

 Just received a firmware update. V1.1.3 Build 202001228 rel 55057.

I run in  AP mode so I can't say anything about improvements. When there are problems, I will report back here. 

@samwardill 

App says:

Modification and bug fixes:

1. Improved backhaul stability and performance

2. Improved Samsung cellphones roaming experience

I also use my in AP mode, so I can't say much about it. I sorted out my connection problems to the DECO farthest from main one, by using a coaxial bridge. That's an awesome tech.

@samwardill Since the firmware update I get a lot of drops of about 20 seconds in Teams-calls (deco farthest  in the chain).

On my middle Netlfix stutters now and then after the upgrade.

Can I upload the old firmware?

The interface doesn't let me.

anyone testing this beta? 1.1.3_20210616

I have 3 P9, running on 1.1.3 build 20201228 Rel. 55057, and I was having issues on performance including drops when I had all the decos turned on, but I noticed if I switch off one of them everything works fine. After almost 1 month exchanging emails with support team and doing loads of tests, etc, etc they have asked me to install this beta.

Update: Just installed the beta... no improvements... back to turn off the second deco so that everything works..... rediculous

  @Brain_Killer I am running the same software. Issues from day 1.

IT WILL NOT GET FIXED EVER!

Running 3 Deco units in router mode has these issues in all software versions.

I run 3 Deco in AP mode. This works fine. But only when plugged into the wall directly.

Support is running a smoke screen as you found out. They will not fix these issues, so they keep wasting your time with these emails. You only get questions from support. Never solutions. 

Get a decent router and run the Deco in AP mode.

If a TP-Link product works you are lucky. If not your money has been stolen.

@ReneP thanks for the reply, really appreciate it. At the moment for me it's not the money anymore, im working from home, I can't continue with this "test subject approach", it's impacting my work. I'm tired of joining calls and say to everyone "sorry, I need to go turn off my deco satellite, I will be back in a couple of minutes". It's a joke, and im surprised the product is still being sold....
