I'm on vacation and the wireless internet access I have is restricted by MAC address. I initially signed up on my personal PC (not knowing it was MAC address restricted) but needed access on my work PC.
So I went looking for information on masking my MAC address on my work PC to match my personal PC. Led me to look into the advanced properties of the wireless card, and I found the answer.
As an FYI I have a Dell Wireless 1490 Dual Band WLAN Mini-Card installed.
Step 1: Go to the device manager (if you don't know how to do this, you don't need to be doing any of this).
Step 2: Expand Network Adapters, Right click your wireless card and click properties.
Step 3: At the next window go to the Advanced Tab and select the "Locally Administered MAC Address"
Step 4: Enter in the value field your custom MAC address, and there is how you do it.
Was pretty happy to find it this easy.
