When 4+ devices are connected it doesn't do well speedwise, where as the nighthawk never skips a beat.
Other r1 issues I've had are:
1 Random wifi disconnect that requires power cycle to remedy.
2 Can't do wifi speed of 50m so my whole internet speed is slower.
Factory reset, turning off ipv6, wifi workaround, turbo mode etc. Don't help. Firmware 1.03.6
