Is there any way to return it as it is not working as advertised....

@QRene hi thanks for replying back.... As when ever i connect my s21 ultra with wifi it shows 6 for wifi 6 band.....but when i connect to extender 2.4 it shows normal bars...more over phones often...

My extender is not supporting wifi 6 on 2.4 G network But on 5G it is working fine....kindly suggest if need to change any setting...also updated the firmware... Host router is Archer AXE95.
