I have a lenovo g505s which has windows 8.1 and another g450 which has windows 7 ultimate. When i run speedtest .net on both of them, i get just 1-3 Mbps on g505s and 8 Mbps on g450. I have opted for the 8 Mbps plan. Every device in my house shows 8 Mbps except the g505s. Is there a problem with the OS? Cuz even if connected to router via LAN shows 3Mbps. I am thinking of downgrading it to Windows 7 but there are no USB 3.0 drivers available. What do i do?

Yes i am using wifi..but even if i am connected to the router via LAN it shows the same speed. The router is a zyxel dual band 2.4 Ghz. But i dont think there is a problem with the router as every other device shows 8 Mbps except the g505s. It is placed next to the router without any obstacles.

Yes it has got 1 antenna. I tried it with a LAN cable but still no progress. No 1 else used the network. I think it maybe a problem with windows 8.1. The windows 7 laptop shows 8 Mbps. If i downgrade the windows 8.1 laptop, i need the usb 3.0 drivers for windows 7. Do they come with the chipset drivers?
