Card works with dual-band but fails to detect 5GHz in Windows 10.
Today we experienced an unexpected power interruption. The laptop struggled with battery life and shut down after a short time because I didn’t realize it was still running. The network also stopped working clearly. Once the electricity returned, I was able to see and connect to 5GHz on the device again. It seems the issue might have been caused by either draining the laptop completely or resetting the network settings. I think Windows 10 could be problematic, but it probably wasn’t intentional.
Review the wireless configurations selected by your router or gateway. A wireless survey with WiFi Analyzer can reveal the exact settings, particularly if the device is set to auto-configure. Devices running on WiFi 4 or earlier may encounter difficulties with WiFi 5/6 access points even when equipped with a 5GHz antenna. Some routers attempt to adjust settings automatically after a power cycle and scan. Occasionally, they choose channels and bandwidth that suit older hardware while others prioritize newer ones. In the latter scenario, older devices may lose connection because they can’t detect the access point properly. Many modern routers offer a “legacy” mode (common in Asus models) that dynamically shifts channel widths such as 20/40/80 MHz, supports lower speeds for older 802.11b/g equipment, and avoids DFS channels to maintain compatibility. The benefit here is broader access for older clients, but the drawback is reduced performance for newer ones—a trade-off of using outdated hardware in today’s networks. To bypass this, you can deploy separate APs for legacy and newer devices. Edited February 19, 2021 by Falcon1986 Incorrect statement
I’m completely lost here, trying to wrap my head around this whole mess. The point is so wild it feels like a whale-sized sentence. I should probably hit it outside and give it a solid blow to the back of the head. It’s not even a proper sentence at all—just a bunch of jumbled thoughts. But hey, punctuation’s fine, that part works. Still, as a total newbie, I’m not sure if this thing actually works in Windows 10 with dual-band wireless. I’ve got an HP without WiFi, and I’m using a Linux VM to mimic it. It’s like the modem is trying to connect to something super advanced but it’s just a regular CAT7 cable.
