The router is AX55.Everything works normally(the extender is in ideal range,the internet works...),the only thing that bothers me is when ,for example,I move my phone away from the extender and move into the range of the router,the internet connection lights on the extender change color from blue to red,something like that doesn't happen to the other people,although they have a different model of extender.That's why I'm interested if anyone has an extender RE605X and if the same thing happens to them.
