WAN/WLAN slower than LAN/WLAN on RT-AC68U

[EnfermeraSexy]

Hello! i've got this router yesterday and finally got it "perfectly" configured. I've got a 400 Mbps symmetric net in my house, but i can't get the full speed through wlan. I'm getting about 320-330 Mbps of download, but if i transfer something from my computer connected over ethernet to my phone, i can see speeds over 500 Mbps.

What could it be? CPU isn't near to 100%

Wish I had that problem

Good discussion of tuning WAN-LAN here: https://www.snbforums.com/threads/rt-ac68u-getting-1gbps-wan-lan-throughput.29471/

Make sure you have at least CTF enabled.

I saw that thread, but it didn't help me. First i have to say that i can get full speed through ethernet (400), but not over wifi. Yes, it could be that my phone/router can't reach that speed but i can get over 500 Mbps in LAN-to-WLAN transfers!

My actual firmware is Merlin 384.4_2, i've got QoS disabled, firewall disabled and aiprotect disabled, everything is disabled.
CTF is enabled but i can't get FA enabled, anyway i read somewhere that AC68U don't have it.

Thanks for your reply

Don't disable the firewall!

Why? I always did it on the Asus routers because the first one I had made internet browsing slower with it enabled

Then I hope you won't be coming here asking for help when your router is taken over by a botnet.

That firewall is there for a reason.

The router's firewall is your first and most important layer of protection from unsolicited attempts to gain access to your network.

Enabling the firewall should not have any effect on browsing speed. If you're experiencing that then there is a problem elsewhere.

The only time you would turn off the firewall is when the network connected to the WAN interface is not a public network. Such a setup might be when the router is being used in a corporate environment.
