R500 internet speed slower than ISP provided.

[joshua_sin]

I setup 2 R500 as a mesh network and using 1Gb boradband network. I find that the connection speed dropped to around 400Mb for Cat6 cable connection and 200Mb for Wifi 5G connection (80 Hz) when I connected internet via R500. I tried to connect my notebook to ISP modem directly and got >900 Mb speed. 
What could I do to improve the performance?

Hi Syamantak,

Here is the output. Thanks for helping.

Joshua,  are you using the root node as bridge or gateway mode?

[joshua_sin]

I am using it as gateway mode

[hayward_kong]

Yeah,  you really need to turn off gateway mode and have it in bridge mode which is when gateway mode is checked off. You should either use the isp router as a router or get a wired router that can handle gigabit. When you use the ruckus r500 in gateway mode there’s a bit of overhead so it can’t route as much when doing WAN to LAN. Most people use ruckus APs in bridge mode. This should address the wired performance.
