The router is perfect. The manual on the website is so-so.
Overall impression - the router is perfect, everything works as expected. The only small complaint, I can not find the detailed user's manual that exactly corresponds my firmware. All the manuals that I have found have some differences from what I see on the in UI, For example, the manual shows the items NETWORK / File sharing but this function doesn't exists, though the manual says my model GL-AR300M supports it. Or the manual says the switch can be configured to switch Router / Access point but the UI dropdown doesn't have this option.
