Zbt3526 no internet on client devices

I tried lede on a zbt3526 which previously had openwrt 1st I flashed dirty way keeping configs
Result clients have no internet over lan and no wireless 2.4g or 5g but the router had internet acces to install luci and other packages
Now I flashed clean but the only change was lede inscription instead openwrt on luci so long story short still no internet to router clients.
Does anyone have some idea?
