Issues with 802.11ac Network Adapter

[elliotbailey]

Hi LTT Forums,

 

I got a new 802.11ac WiFi adaptor (the kind with antennas) that should support both 2.4Ghz and 5Ghz WiFi. This isn't immediately an issue because my router has a network for both frequencies. However, my PC is unable to find my 2.4Ghz network (or any network at that frequency for the matter). This might not sound like an issue, however it prevents me from doing certain things like connecting to LAN games with my friends/siblings. Furthermore, although counter-intuitive, if anything I've noticed the 5Ghz network is marginally slower than the 2.4Ghz one. All I can find online are cases where people operating at 2.4Ghz are unable to connect to 5Ghz. 

 

I've tried reinstalling drivers but that didn't do anything. The adaptor is listed in device manager as 'Broadcom 802.11ac Network Adapter'.

 

The model of adaptor is 'ASUS PCE-AC56 AC1300 Dual Band Wireless PCI-Express Adaptor'.

 

Does anyone have any ideas of how I would be able to find and connect to 2.4Ghz networks?

Welcome to the forums!  

 

Download the actual driver from Asus. Sometimes Windows will install the basic drivers and they don't work as well. 

 

I assume you're using Windows 10
