@David-TP 

Thanks for sending, I installed it and unfortunately no change. 

I also tried the router with my phone SIM card and it worked perfectly. The weird thing is that both cards use the same network (3 5g), although they are different companies (3 mobile Vs spusu). 

I have looked up more solutions and I would need to edit some of the router settings, however this is limited because of the app interface. 

I have also raised a call with the technicians, but they seem to have a backlog. 

Any advice you have would be appreciated.

could you also send me beta firmware for testing?

  @David-TP könnten Sie mir die Beta Version auch senden wäre super .
