hardware offload (HW) hap ac Lile?

my hap ac lite is using 6.48 OS now. my bridge-wan is hardware offload (HW) now, but my bridge-lan (bridge wlan1, wlan2 and ether2) cant be HW. do dou have sugestion ?

I stop rstp, vlan filtering, igmp, and mstp but its still cant be HW. please help

Only one bridge can be hw

so i need to use between bridge-wan or bridge lan right ?
which one os better ?

Whichever has the greatest port to port traffic, e.g. if you have a PC and a NAS connected to a couple of ethernet ports then the bridge including those. Also note that wlan interfaces cannot be hardware accelerated as the traffic is handled by device driver code running on the CPU.

i still cant find the way to hw the bridge lan, is that because of bridging wlan with ether 2 as “bridge-lan” ? as u said wlan uses CPU

so how to reduce cpu load for my bridge-lan expecially when someone is using IDM to download, or open many tabs chorme at the same time on my WLAN 1 ?

Set hw=no for the ethernet interfaces attached to the other bridges under /interface bridge port, in Winbox this is the ‘Hardware Offload’ checkbox on the General tab for the ports under Bridge > Ports.

Hardware offload is only for ethernet to ethernet traffic for ports attached to one bridge, it will not speed up anything using WLAN interfaces or routed traffic to/from the internet. To improve performance for these get a more powerful device e.g. hAP ac^2
