I recently purchased a ASUS PCE-AC68 802.11ac Wireless adapter for my Windows gaming machine so I can benefit from the speed that my Apple Airport Extreme's 802.11ac wireless offers.
After some tweaking I've finally got this setup working perfectly. Offering my Windows 10 Gaming PC a 500Mb/s wireless connection while being three rooms away. Here's what I did to force the PCE-AC68 to join the 5GHz ac network:
I found that when I joined the new ASUS adapter to my Airport Extreme's wireless network, the adapter defaulted to 802.11g speeds and 2.4GHz. I could simply disable the 802.11b/g network on my Airport, but I didnt want to limit my connectivity options (plus I have an older iPad that only supports b/g).
The better option is tell the ASUS adapter to disable its ability to connect to b/g networks so the only wireless network it sees are the a/c networks.
To disable 802.11 b/g bands do the folling:
- First join the wireless network and test to make sure its working.
- Right click on the wireless network bars on the start bar in the lower right and select "Open Network and Sharing Center
- Select the "Change Adapter Settings" option from the left hand side.
- Right click on your wireless network connection, select "Properties" from the dropdown
- Click the "Configure" button
- Select the "Advanced" tab at the top
- On the scrolling list look for "Disable bands" and select it.
- On the drop down list of options select "802.11b/g"
Your adapter should immediately rejoin the network, but this time at 802.11ac speeds. To verify your wireless connection speeds right click the wireless bars in the lower right, select the Network and Sharing Center, click the Wi-Fi connection. The Speed section shows the connection speed between the wireless adapter and your router.
If you're seeing anything above 300Mb/s you're connected via 802.11ac wireless. Want faster speeds above that? It's all about location, location, location. Try moving your adapters antenna into a corner (no closer that 1 ft from any walls).
