I have a RE505X connected via onemesh to Archer AX75 (HW V1.0, Firmware 1.0.6).  When using a voip app on iphone and connected to Archer AX75, everything works well.  When moving and eventually switching over to RE505X, downstream audio is lost (cant hear other party but they can still hear me).  When walking back towards the Archer AX75 full audio functionality is restored (while the call is still active).

How to resolve this issue?
