Hi i just signed up here after some googling and your site has a lot of guys with alot of information regarding routers . I'm buying a asus ac5300 and after reading im best to put a merlin firmware on it . Can anyone tell me which one i need .i clicked on merlin and there's a lot of different firmwares for the ac5300 . Im no tech guy so simple instructions would be great . I brought the router for online gaming for my ps4 which is wired and for good wifi. Any help would be great .thank you
