I have tested this last version and the problem with wireless continues.
symptoms: I transfer a file on my local network the speed is good, at the same time I ping a network address with lots of lost packets, I try to open a website it will not open before I stop the transfer. Most of the time the connection is lost in a matter of seconds and the wifi ssid is no longer detectable (either with notebook or phone), openwrt is then accessible over the local network but not over wifi.
I have limited speed of transfer to ~2MByte/s but this is not feasible in the long run.
did not find any suspicious entries in system or kernel log.
setup: notebook connected over wifi, local nas.
I connect with my notebook, iwconfig shows a speed of max 144Mbps on the notebook interface independent of configured channel width.
I flashed the above mentioned pcwrt ( based on openwrt 19.07 ? ) for testing and these symptoms do not show. iwconfig shows 300Mbps, sometimes 270MBps. Speed is fast (~10MByte/s) and consistent and no packet loss only slight increase in latency to ~30-40ms. Seems stable however I would prefer stock openwrt.
Is there any stock openwrt 19.07 available for the 4C ?
