I am running a Netgear Wireless Card on my Desktop tower. I got it working this way....
On the Phone....
Opens up a menu screen:
Screen opens up with:
Click..TETHERING AND PORTABLE HOTSPOT
The USB Tethering is off
Portable Wi-Fi hotspot is checked ON
Go to Configure Wi-Fi Hotspot
The SECURITY tab
in that tab I clicked "OPEN"
I am surfing the net. 54.0 mbps.
I notice it drops when calls come in. Sometimes with texts it does also.
Hope this works for you.
