So i just purchased the acrcher c7 in hopes of improving my wifi range and up/download speed. Since my plan is 400mbps i didn't forsee any problem for the router to push that on the 2.4ghz setting only but my dowload is very sluggish peaking 30mbps then going down to15-20. Is anyone else experiencing this or is it just a faulty router? P.S. the 5ghz pushes far better around 300mbps when I turn it on. Thank you!
