Just installed deco M5 system on our home And noticed my modem/router reports different MAC address for base unit. The modem identifics the rest 2 as :F1 as the TP link app reports :F0, which is correct to that device.

what is wrong?is this normal? besides, when I logged out of the app, I couldn't log back in because my password was wrong, well it wasn't. I had to change my password several times. last time the app said my access is blocked and i can't login to deco due to too many attempts. try again in 30 minutes. after half an hour it worked.
