Might be a stupid question but I read that you can disable to setting to switch between wired and wireless and have them both active at the same time. Does this boost the DL/UL speeds?
No. Your DL/UL speed depends on the outside connection, not the connection speed between you and the router. If you have for instance a 25Mbps connection, that is all you will get when talking to the outside world. Even if your WiFi is rated at 300Mbps, and your wired is 1,000Mbps.
