I have a NetGear DGN3500 router, running OpenWrt 18.06.4.
I no longer use my aDSL port, since I've setup one of my eth lan ports to be a WAN port. I'm basically daisy chaining from my provider's router to my OpenWRT router.
Anyhow, wifi on my netgear isn't as good as I'd like it to be. I'm pretty sure it's just a limit of my router (cpu, etc).
My "stupid" question is: would disabling my aDSL port on my router help in perhaps speeding things up a bit, or at least free up resources on my router? And how would I go about deactivating my DSL? Is it just a matter of going in LuCI -> Network -> Interfaces and hitting "Stop" on the pppoe-wan interface (my case called "WAN")? Is that all I need to do and will it keep it so even after reboot?
Thanks for your replies.
