We have 400 mbps service internet service from Spectrum and have an ASUS RT-AC3200 wireless router for use at home. Generally speaking all works well, but I'm finding a wide range in connectivity speeds between laptops when used at home. My wife's and my work laptop both have download/upload speeds in the 400mbps / 25mbps range. Plenty fast, no worries. Our new Dell Inspiron laptop (model 3793, Intel Core i7) for general family use can't get more than 55mbps / 22mbps range. It's a brand new laptop. Is there a setting or something I can do to boost the speed? Any suggestions on troubleshooting? Thank you.
