@David-TP  after upgrade to 1.3.0 i get error previously i use 1.2.8 for long time without problems now i get disconnect to router  spike in ping via wifi network. I use it as mesh system not to acces router.

  @David-TP My internet connection became really slow after the firmware upgrade. I need support to fix it.

I'm on V3 Firmware Version: 1.3.0 Build 20240830 Rel. 50008 not running any extra features,

Is it possible to roll-back firmware?

EDIT: When using client acceleration, I get more speed.

  @AbulSader I will try during weekend to downgrade based on top of this you need to do recovery downgrade here are steps how to do it https://community.tp-link.com/en/home/forum/topic/702312 (i still not do it i want to do it during weekend)

I finally got some time to reinstall the 1.3.0 update. Indeed, the QoS settings seem to be problematic. When I opened the settings, the bandwidth was throttled at 0.1 Mbps both up and down. With this on, the behaviour of my network doesn't surprise me. Turning QoS off indeed gave me much more expected speeds.

I blame two factors:

• The update must have enabled QoS because I didn't have it on before the update.
• The design of the mobile (iOS) app. Take a look at two screenshots:
  • This one shows the QoS settings page, which I must have gotten through. Because both scene acceleration and client acceleration were off, I thought that the entire QoS feature was turned off. I didn't notice that I had to scroll down.

• This one shows what was below it. The most crucial pieces of information were just two lines further.

I will try to keep this version on for now. If I encounter any further issues, I will make sure to collect the logs and post them here.

This link redirects to EU version only, can I upgrade the firmware of my X60 US using this as you indicated "/"? If not, where can I download the X60 US V4.2 firmware that supports captive portal under guest network?

Hi David! I purchased my deco by myself and not thru isp. Our ISP only sells the x55 units and not X60 ones.

I tried updating to the firmware you provided and it did update well, however, the one you posted where Deco X60(EU/US)_V4.2 1.3.0 Build 20240830 won't push through with my Deco US V4.2. Perhaps you could provide me one?
I also saw a difference in the support list of the bin files, the 1.2.9 has 2 more special id than the 1.3.0 you posted. The highlighted ones in the 1.2.9 are not seen in the 1.3.0 build.
Please see the zip file i attached, apologies for the quality, i cannot upload more than 10mb
