dell 1802 802.11a/b/g/n adapter using driver version 10.0.0.341 (qualcomm atheros)
The download time for a 100kb file from dell.com took from 90 - 110 secs. Comparable time on a mac is 15 secs and a dell e6420 was 20 secs.
Research seems to find the driver is for win 10 only and this machine is win 7 pro 64 bit.
Does anyone know why this download speed is so slow?
I also faced same problem while working on my blog, i then noticed my firewall was aborting network access, I don't know why? But I resoved clearing my temp files by " CTRL+R -> %temp% ". And restarted, it worked for me. May be it works for you too.
I am also facing this problem while using Windows 10 on my laptop then I update my windows and download the latest wifi drivers now I am getting high download speed on my laptop.
