I have a TP-Link WR541G/542G router which I would like to utilize as a switch to connect my xbox 360, blue ray player and TV box to the internet. The switch is connected to a powerline adapter and another adapter is connected to the main router Huawei HG533. I have tried to follow your instructions I found in the thread however it did not work. I am not sure what I am doing wrong. Could you help please?
Perhaps you mean using the TP-Link as an AP/switch.
To do that you turn off the DHCP in the TP-Link and give it a static IP address that is in the network range but outside the DHCP address assignment range. That static address has to be entered in both the TP-Link and the main router. So for example if your Huawei has a gateway address of 192.168.1.1, give the TP-Link a static address of 192.168.1.2 and then save a few static addresses, so make the DHCP assignment range on the Huawei 192.168.1.16 to 1.254.
For the TP-Link wireless radio use the same SSID and security type/password, but a different radio channel than the main router if it also has wireless.
