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?

OK,thanks for helping.
How can I turn off gateway mode without reset it? I can't untick the it.

Hi Joshua,

I  don't think you can change the AP mode from gateway to bridge.

You have to factory reset the APs and reconfigure Unleashed to bridge mode.

Thank, 
Do I need to reset the mesh AP too if I want to change the root AP to bridge?

[syamantakomer]

Please try copying mesh configuration from Unleashed (current settings) and when you reconfigure master AP then use the same mesh configuration (mesh SSID name and passphrase). I think mesh AP should be able to communicate to root.

Just in case if above does not work, please factory reset the mesh AP for reconfiguration.
