Asus X99-Pro supports 5GHz Wi-Fi connectivity.
The Wi-Fi card on your motherboard is 802.11ac, which typically means it should handle 5GHz channels. But it’s not detecting any 5G networks. In the Device Manager, under the Broadcom 802.11ac adapter settings, 5G isn’t listed as an available option (advanced tab). Screen snippets show this issue clearly. Spoiler: something’s blocking the connection.
Probably due to a color banding problem. Because the board was from earlier, 5GHz bands were very restricted back then. My setup used an x99 MSI Gaming ACK 7 which only supported 2.4GHz Wi-Fi.
5ghz frequency ranges, also known as the actual visible spectrum your Wi-Fi adapter detects, and your router's own 5ghz channels. When these aren't aligned, detection fails. This problem has been observed in older devices.
Your router could be operating on a WiFi channel that the Wi-Fi chip doesn't recognize. 5 Ghz works differently; in the US some frequencies are reserved for radar systems, so certain channels are blocked. Over time more channels have been added, but older cards may not support newer ones. The 802.11a standard was the first to use 5 Ghz. It seems your card does support it. If you're unsure, try switching to a different 5 Ghz channel. USB dongles often don't work well. You might want to replace the built-in Wi-Fi module with one that fits in a M.2 slot on your board. Consult your motherboard manual for details.
I've tried this too. Still nothing working. It's holding up okay on 2.4G right now. The main issue pops up when I'm moving bigger files in or out of my server, but that's rare now that everything is stabilized after the shuffle. By the way, the Deluxe model seems to have a three-cable antenna, while the Pro has two—probably for more channels.
