Hello DanYingLing

If other devices are getting full speeds have you tried to swap out the Ethernet cable or try to connect the xbox via wireless and see if its getting faster speeds?

i have tried diffeent cables and wireless make no difference. tryed to set up port fowarding and idk if i did it right 

but that didn't help either. wiped my xbox and reset router to factory spec. none of which did anything to help.
