Hi all,

I got some problems with my newly purchased Deco E4R and I have existing M5 currently on the network.

After adding both E4 to the network, I immediately updated the firmware as prompted on Deco App (1.1.0 Build 20190823 Rel. 43466)

Both successfully updated and one of the E4s can't work in 5Ghz band. So, I checked for the latest version that's availble in my country which is Indonesia. Can be found here https://www.tp-link.com/id/support/download/deco-e4/#Firmware

Then I manually updated both E4s to 1.1.0 Build 20190910 Rel. 66772, but now both E4s just working as single band (2.4Ghz only). This is so fustrating and I don't know what to do now to make them both to work in dual band.

Before: 1.1.0 Build 20190823 Rel. 43466 Global Version

Now: 1.1.0 Build 20190910 Rel. 66772 ID Version

2.4Ghz Only https://image.prntscr.com/image/rPcajTvVTCCfHDGAfP_5Hg.png

Thank you

Updates:

Now they deleted the firmware file which I downloaded from https://www.tp-link.com/id/support/download/deco-e4/#Firmware.

Here is the file before it got deleted on Indonesia's official website https://drive.google.com/file/d/1o_kX27K0CAW5rIj9wUvNRIftycW3zoKn/view
