Since the last Tether App update, I'm pleased to see that my two TL-WPA 7617 powerline extenders are now recognised as One Mesh units in the Tools section of Tether for my Archer MR600 modem router.  They were set up as one mesh units, but until this update, never showed in the Tether App.

It shows the correct number of Connected Clients, but fields such as Signal Strength or Link Speed 2.4 and Link Speed 5 never seem to change.  Signal stength seems to permanently show 4 bars.  Link Speeds are permanently on 0kbps.  Is this normal?  Or should I expect to see more information.
