RT-AC5300 ASUWRT-Merlin 384.19 impossible to connect to Twinkly Led Lights

[Antoine ZAÏNE]

Hi, just bought Twinkly's gen II Icicle and Strings lights that only connect to 2,4 Ghz Wifi. Not able to connect it to my Asus RT-AC5300 Router to make it work in the app (Ios or Android). Tried to connect to my ISP box (I have 2 ISP's at home: one modem going to my Asus and one ISP' own modem router) and it works fine... No WPA3 in the Asus RT-AC5300 (running Merlin WRT). I have 2 separate networks (1 for 2.4Ghz and the other for 5GhZ)... Must be a configuration problem but don't know what to change... I can see the twinkly linked to the ASUS router as the Blue Dark Led is fixed on the command, I can see in my ASUS router that the Twinkly has an IP (and I can see it's mac adress) but the app never can find the twinkly on the network!!! As soon as I change my router to my ISP modem router it's ok... HELP!!!

Did you connect them to a Guest network perhaps?

 

[Antoine ZAÏNE]

No pretty sure I didn't do that, it's connected to my own 2.4Ghz network

I don't mean an external 'guest' network. I mean your own Guest network (which is isolated by default).

Yes, I've understood, I never activated the guest network in my Asus. I'm logging to my private network as well as all my connected objects (iphone, macbook, wifi speakers etc...)
