The following setup d-link 2888a as a modem in bridged mode, my connection is VDSL, pppoe, Egypt-WE, & using a tp-link ER605v2 as a router with openwrt, my PCs& TV will connect to it using ethernet, & finally a tp-link VR600 as a dumbAP, which all mobile devices & my printer & Laptops will connect to, then I'll setup sqm/cake on the WAN interface if I understand correctly, will this work fine for all my devices, will it work at all, will I be getting the benefits of sqm on both clients connected directly to my ER605 & others connected through the VR600 whether wirelessly or through it's ports?
-Edit#1 also the ER605v2 looks like a business router or something with a punch of features that I don't know/don't care about, will it be okay for openwrt as a home router, btw this is the one I'm talking about: https://www.amazon.eg/-/en/SafeStream-Gigabit-MultiWAN-VPN-Router/dp/B08MH4VLR3 no idea what safestream Omada SDN, cloud vpn, & all those bs mean, does it make any difference for my use case? or is all that software shit that'll go away with openwrt replacing the stock firmware?
-Edit#2 what's an omada controller & do I need one?
