802.11n base station and 802.11g CPE

hello teacher:
I put a:

  • base station with Rb/433UAH,radio boards R2N and 2 antenas omnis (working on 802.11n)
  • Cpe CPE ubiquiti nano loco2 (working on 802.11g)

My question is whether any problems exist for the difference in protocols between the base station and CPE

thanks
