RT-N66U - Wired cable speed slower than Wifi?

[awaisuk]

Hi,

So ethernet cable connected from router to computer, the speeds are very slow compared to Wifi. On Wifi the speeds are normal.

I tried connecting using the same cable to modem, and the speeds are fine. Only when connecting to router with same cable, the speeds are slow.

The speeds are limited to around 30mbps, when I have a 150mbps connection.

Why is that?

Thanks.

Make sure you are using Cat5e or Cat6 cables - older Cat5 cables won't be stable with Gigabit devices.

If you had enabled it then try disabling QoS.
