I think Kathiravan only wanted to make sure you have the latest bootloader. Looking at the documentation, I don't see a 1.2 GHz frequency level for this platform. Konrad

But from the merchant's publicity, ipq6000 is 1.2GHz: https://wikidevi.wi-cat.ru/Qualcomm/IPQ6000 https://www.gl-inet.com/products/gl-ax1800 (CPU Part) https://www.alldatasheet.com/datasheet-pdf/pdf/1246071/COMPEX/AP.CP03.html Thanks, Chukun

Or perhaps, if there's a cpufreq driver (I don't know), check syfs Konrad

The CPU frequency on OEM firmware is 1.2GHz. 2. The CPU frequency on the BSP kernel is 1.2GHz.
