Hi All
 

i used my iPhone 13 to set up the range extender (RE550).

whenever I scan for wifi networks, it only shows my main router and 2.4 GHz network of range extender. The only time 5 GHz network shows up is why I "forget" my main router which is quite bizzare. So everytime I am on the second floor of my house amd trying to use the 5 Ghz network, i click on forget password of my main network and 5 Ghz network appears immediately.

Strangely, I have 3 other iPhones in my house and none of them seem to have this issue. All other iPhones and my laptops detect all three networks i.e. main network and extender's 2.4GHz and 5 GHz network. Its only this iPhone 13 (which I used to set up the extender) seems to be having this issue

Any recommendation?
