OK, So I also have the download speed issue with the AC 3160 and Windows 8.1. After fighting with Dell and of course them blaming it on my Wireless Router... I do have
an old WRT54G, Version 6. I uninstalled the Dell driver and installed Intel's driver. My download speed on any other device in my home is 20MBPS. With my brand new
Dell system, tops is 5MBPS. I have tried numerous things suggested out on the Internet to correct this issue with no Luck. Very, Very frustrating as others with this issue
would know. Tried different Wireless securities, The following 3 commands on my machine:
- netsh int tcp set heuristics disabled
- netsh int tcp set global autotuninglevel=disabled
- netsh int tcp set global rss=enabled
Nothing so far has corrected my issue. Anyone that has any ideas, Please Please a response, it would be greatly appreciated, before my new Dell laptop
ends up in the lake or the trash can. Thanks for reading.
