I running my RUT950 with firmware RUT9_R_00.07.01.1, but VPN tunnel it was crushing verey oftem it was not stable . Usage CPU is too high. I decided downgrade firmware to RUT9XX_R_00.06.08.6 and after downgrading a can't change default pass. When I change pass on ssh and change default password flag using "uci set teltonika.sys.pass_changed='1' " then router after log on web, system automaticly logout my and redirect to start page with log form.
How can I fix this issue??
