 +Note that factory u-boot does not properly round value when calculating clock divider for UART speed. Real value is close to 119050, quite far from 115200, that can cause glitches. Linux kernel use a better rounded value, to a value a little bit lower than 115200.

-It appears that the only difference between this device and the faster E5400 is the firmware. When running OpenWRT, the device reports speeds equivalent to AC1200, double than its advertised N600. More testing is needed to confirm this behavior (July 2022).+It appears that the only difference between speed limited devices and the faster E5400 is the firmware.
