CM1200 to Orbi AX6000 slows download speeds with WAN Aggregation

I had it disabled as i stumbled upon that forum as well but my speeds remained low even after factory resetting everything and doing it all. However I think i may have fixed my issue. Enabling extended upstream transmit power seemed to have done the trick it rebooted as i checked the box so ill see what occurs in 24 hours and throughout the week and check if there are any drop offs im currently getting 850-950 mb/s again via wifi now with aggregation active so hopefully thats all that needs to be done.
