It seems you're experiencing a common issue with Broadcom wireless drivers (broadcom-sta-dkms) on Ubuntu 25.04, where your 5GHz Wi-Fi is limited to channels below 50, even though your router and the same hardware on Windows Server 2022 support higher channels (like 106). This points to a driver-level or regulatory domain misconfiguration within your Ubuntu installation. https://www.upsers.us.com
