Hello TP-Link community,
After upgrading to 1.5 firmware, there is a huge performance hit, it became almost impossible to manage the Deco with Deco app, as it almost always unable to connect or looses connection just after getting connected (doesn't matter from what phone I try to access, and if I'm on the WLAN or from the MOBILE WAN).
The access thru the web browser to main Deco (192.168.68.1) became also almost impossible as it barely responds, and it takes me dozen of tries just to load the login page.
There was also hit on the internet performance - with 1.4.3 firmware I was hitting 570-580Mbps down and 75Mbps up (600/60 Fiber connection). After the upgrade to 1.5 I can get only 460-470Mbps down and 60-65 up.
=======================================
Tried resetting all 3 units and configuring them again about dozen of times, trying to find out some pattern of the issue. Also tried setting up different unit as the main Deco unit, with the same issues in the end.
There is a huge (!) problem if the unit is connected directly to the internet, just after the internet setup stage, the Deco app looses connection to the unit.
I was able to configure the Deco if I disconnect the WAN cable, and at the internet setup stage if I set static IP internet (with made up values, just to keep it offline).
In that way there was no problem to complete the initial setup and thereafter to access all the features thru the Deco app without loosing any connection in the Deco app.
Once I set the internet back to Dynamic IP, all the issues come back again. And I'm even not able to access the Deco thru the app to change any values as it always loses connection (and as mentioned, doesn't matter if I try to access from WLAN or MOBILE WAN).
As mentioned at the top, there is also an issue accessing the main Deco unit thru the web browser, it takes forever to load the login page and if I even able to login, it fails to load the main page thereafter.
Another time I was able to complete the initial setup is if it was configured only in Access Point mode, there also was no problem to access the Deco unit thru the Deco app.
Once I set it to Router mode, it just freaks out again.
EDIT #987324: The ONE AND ONLY way now to access the configuration thru the Deco app, is to disconnect the WAN cable from the main Deco unit, then and only then I'm able to access and change any of the configuration without any app connection issues. There is definitely something related to WAN that creates huge load on the main Deco unit so it becomes unusable with the Deco app.
=======================================
Before the upgrade to 1.5, there were none of the issues I'm experiencing now with the 1.4.3 firmware.
There is definitely some issue with the 1.5 firmware which maybe eats up the unit resources (cpu/ram) and causes these issues.
So if 1.5 is non-downgradable, how do you solve my issue?
=======================================
Have to mention that I'm disappointed from the TP-LINK TECHNICAL SUPPORT email answer which just ignored from the issues and only referred me to the FAQ section of "resolving interned speed issues".
1. I'm always getting into this situation in the Deco app.
The LEDs on Decos remain solid white.
2. My ISP is Partner Communication here in Israel. The only thing I can tell, is that after getting the fiber optic cable into the apartment, there is only media converter (D-Link DMC-G01LC), and main Deco unit is connected directly to the media convrter.
3. As a workaround to getting into Deco settings with the Deco app, I had to disconnect the WAN cable as I already mentioned in my first post.
Changed to DNS as suggested to Google DNS, and just after plugging back the WAN cable, nothing changed, the problem is still there.
