Change the AP Band for Mobile Hotspot auf Huawei
Huawei sets new hotspots to 2.4 GHz because that band is supported by every WLAN chip ever made, including cheap smart-home gadgets and older laptops. The trade-off is speed: 2.4 GHz has fewer non-overlapping channels and gets crowded fast in apartments or offices, which drags down your hotspot throughput.
If the devices connecting to your hotspot are newer, switching to 5 GHz gives you higher real-world speeds and less interference, though the range shrinks slightly compared to 2.4 GHz. The setting sits behind an advanced toggle in EMUI, so it is not visible until you enable it.
To change it, go to Open the Settings ➔ Tap on Mobile network ➔ Tap on Tethering & portable hotspot ➔ Tap on Personal hotspot ➔ Tap on Configure hotspot ➔ Enable Show advanced options ➔ Tap on AP band ➔ Choose 2,4 GHzor5GHz ➔ Confirm with OK.
Keep in mind that switching to 5 GHz can drop connections from older phones, smart-home devices or accessories that only support 2.4 GHz. If you regularly connect a mix of old and new hardware, staying on 2.4 GHz avoids reconnect issues, even though it caps your maximum speed.
