Many router makers offer the old firmware so go back to what worked.
As to your setup, only you know your goals and what is your Internet source. I can't tell from your post.
I've been keeping up with the firmware updates for my Asus RT-AC68U but it seems that as of the last one it is no longer working as a router for my Ethernet connection. It's seen by Windows 7 as an internet connection with no network and it lists itself as a wireless network. If I change it to an access point then I lose my internet connection because it wants a separate router for that.
Is there a work around or do I have the settings all wrong?? I love the router for it's speed but this Mesh thing they've added is screwing me up.
Any help would be greatly appreciated.
Thanks to all.
