Slow internet on new interface on Flint 2 (GL-MT6000)

Hi All,

I recently bought the new Flint 2 and thought it would be a great way to learn some networking that I've always avoided. One of the things I thought might be something worth trying is setting up another wifi SSID that is exposed to tailscale for some of my IOT devices.

To test the configuration, I:

  • Set up a new SSID, EZ1-TS. Configured exactly like the default SSID
  • Set up a new interface, LAN_TS. Set up exactly like the default interface, LAN, but without any devices connected to it. Also the DHCP assigns IP's on 192.168.7.X instead of 192.168.8.X
  • Attached the firewall policies for the default lan to the lan_ts interface for testing purposes.

The issue is that when I'm on my normal SSID, I get 500 Mbps, and when I'm on EZ1-TS, I get less than 1 Mbps. I switched the EZ1-TS wireless SSID to the default lan interface I get the full speed, so I believe the issue is with the lan_ts interface. However, I cant figure out whats different from the other lan interface as I've copied all the settings but the device setting. I've even ssh'd in and copied the config from the lan interface to the lan_ts interface (just removing the device section) .If I attach a device to the lan_ts interface, it breaks the interface and I can't connect to the SSID and get an IP.

Do you have any suggestions on what I need to do to get it to work at reasonable speeds?

What this interface's gateway is?
If the Tailscale, please check your tailscale virtual network speed, probably the tailscale bandwidth is not high.

Hi @bruce

The interface gateway is set to the default wan.


I haven't set up tailscale on the router yet. I'm fairly confident on how to set up tailscale for the subnet, but wanted to make sure accessing the internet is fine before I set up tailscale. It currently doesn't have the tailscale plugin installed.

The issue seems to be the LAN_TS interface (or bridge) configurations. If it copies as the default LAN, it should same speed with the LAN. To try to move one LAN (like lan4) port from the br-lan to the LAN_TS, and test the cable LAN speed.
