problem in metal2shpn

i have bought 2 metal shpn, os version 6.29,
if i stopped the data transmission the ping becomes normal and ccq goes up to 105% but when the data started the ccq goes down to 30% - 35% , none of the user able to use internet properly, both devices creating problem in same time. wht to do.
n there is no registration on 2.4ghz Chanel 2012 t0 2462 only 2472 and 2484 is working but data transfer speed is very low.

Antennas, orientation, signal levels, protocol, environmental scan, settings?
