8.1 networking troubles

As a forward I have spent a large amount of time on this already:

Alright, this problem spans 3 laptops which I have used to test my system.

Laptop 1) Lenovo S415 laptop, Broadcomm 800 adapter: Originally the device did not have the drivers for the wireless chip, on windows 8 the system is fixed. Upon update to 8.1 no driver will work with the network. Conducted troubleshoot (listed below). Failure.

Laptop 2) Asus 13.3 inch Zenbook, Intel wireless: After update to 8.1 and a simple driver update, no issues.

Laptop 3) Asus Q501LA, Intel wireless: Very inconsistent connection, often limited much like the S415 but sometimes will connect to the network for a short time. Conducted troubleshoot, still very inconsistent.

All other devices connect without trouble, including: Ipads, Macbooks, windows 8 or lower laptops, desktops (hardwired and with wifi), all types of cell phones.

My router is a netgear WNDR3400 (http://www.netgear.com/home/products/networking/wifi-routers/WNDR3400.aspx) and I have the latest firmware installed.

I really am out of ideas of what to do next, suggestions?

Troubleshooting Conducted:

-Update Drivers

-run ipconfig\all


netsh int ip reset C:\resetlog.exe


netsh int tcp set heuristics disabled

netsh int tcp set global autotuninglevel=disabled

netsh int tcp set global rss=enabled
