Good Wireless Adapter for faster internet?

[Joeliolio]

I recently went from 2 Mbps internet to 50 Mbps internet with my new company, and when I speedtest on speedtest.net. I am only getting about 16 Mbps for my speeds, while my hard wired computer is getting about 50 Mbps or sometimes even higher, so I think it is my old wireless adapter which is a NETGEAR WN111 Wireless-N 300 is not capable of connecting at these speeds. Is there a wireless adapter for a desktop that can get near hard-wired speeds? This is going to be for my self built PC in my room, which is not that far from the modem we received, if it's not my adapter and it's maybe a setting on my computer let me know. If it is, please recommend some good picks for me. I do play FPS and MOBA games on my PC so I would like to possibly have it keep my ping at the same or even lower if possible, thanks.

Thanks for your guy's help.

another thing to consider is your router could be the problem as well

WiFi performance is greatly influenced by environmental conditions.

How far away from the router?
What is in between?
Interference from neighbors?

It's maybe only 20-FT away, 2 walls, no interference from neighbors.

If you have no interference from neighbors you are one of the few or you live way out in the country where neighbors are 100s of feet away.

The network card is only 1/2 your problem. It must match your router to get optimum performance. The card you have with a router with similar features should easily be able to exceed 50m. You will of course never get 300m but 50m should be very possible.

If you were to replace your device with 802.11ac you must also have a 802.11ac router.

I would try a USB extension cable or moving your computer in the room to see if it makes any difference before you spend money on new equipment.

The normal software I recommend to check for interference from neighbors was INSSIDER but they now charge for this package but if you dig around you can find the old free release which they still allow you to use.
