I have 2 Asus TM-1900 routers, set up as (modem -> router -> AP). I have been using this setup with no issues until recently when I upgraded my speed from 300/300 mbps to 500/500 mpbs.
I believe my download speed is being throttled by my secondary router (AP). As a test, I have my desktop connected to the main router, I run a speedtest and get 500/500, Then I make a connection between one of the LAN ports on the AP to one of the LAN ports on the main router, and after a minute or two, the speeds become 300/500 mbps.
Router 1 is 192.168.29.1 subnetmask: 255.255.255.0 default gateway: 192.168.29.1 DHCP enabled IP Pool start: 192.168.29.100 IP Pool end: 192.168.29.254
Router 2 (AP Mode) is 192.168.29.2 subnetmask: 255.255.255.0 default gateway: 192.168.29.1
QoS is disabled.
All the cables I'm using cat5e, and the routers have gigabit ports. Is this a limitation of the routers or the network setup?
