I have a 100Mbps internet connection at home. When I connect my laptop direct to internet ethernet port, I get around 90-95Mbps download speed on speedtest. When I place a wireless router(Belkin N Wireless router) between and connect to its wireless network, run speed test, I get around 20-25 Mbps, even if I stand right on top of wireless router.
I get same speedtest results on all wireless devices(smartphones, tablets) around 20-25Mbps. So my question is it normal to have slower speed on wireless network than wired network? I was expecting atleast 50Mbps on wireless devices. I have tried another wireless router with same results. Does buying an AC router will help?
