We are so sorry for the trouble caused here, and we totally understand your feeling and frustration. We will try our best to help you and give you a specific answer. 

May I know when and where did you buy this RE450 V3? 

Except the Onemesh feature, is there any other network requests about the extender? Like the ethernet port, the wireless speed or so? 

Thanks for your kindly support and understanding in advance. 

Good day.

Hello, from the compatbility list, the RE500 is not included, and considering the date for firmware with onemesh for RE450 V3 has been postponed, it has been withdrawn from the compatibility list to avoid potential loss. 

And the RE455 is not ready for Onemesh now; instead, it is not available in the market now. 

If you want to use the onemesh feature, you can contact retailer whether you can return the RE500/RE450 and get a RE300, RE205 or so. 

May it help.

As listed in the compatibility list, the RE500 won't support Onemesh; while the marketing plan varies as time goes by, we cannot guarantee that it will NEVER support Onemesh, but at now, it won't. 

And to use the onemesh feature, it is suggested to order those devices which support Onemesh already. 

Good day.
