It runs fq_codel on the USB-3g dongle modem interface, and it runs very well at rest. I put it inside a car, and while driving, I notice some induced latency: https://www.dslreports.com/speedtest/6354936 Can someone who has some understanding of 3g/4g internals shed some light ? Could the 3g/4g modem be buffering due to varying strength of the signal or due to handover in base station ?
