My wife & I both have Lenovo laptops and her 1 year older I5 Ideapad gets 56 Mbps download speed vs. my 36 Mbps download speed on my Lenovo Flex3 I7 laptop both connected to the same D-Link home router connected to ISP Comcast. Why the difference? I just uploaded the Intel Network Adapter and Bluetooth drivers on both machines to the latest drivers and still the same speed difference. Both are running Norton 360 Security suite and have mostly the same software on them (except my wife plays lots of games). Both laptops were originally running Win 8.1 a month ago but were upgraded to Win 10 (I think her laptop still had the faster download speed prior to the update but I'm not absolutely sure - I rarely used her laptop except to fix stuff). I know this isn't a major problem but I'm trying to understand why the difference. THANKS IN ADVANCE!
