Maximum Transfer Speed on Concurrent Dual Band Routers

The maximum possible rate depends on the specific router, having adapters with the same capability, and the distance/obstructions/interference that lie in the wireless path.

Personally, I have not yet found any that will stream full 1080p BluRay at any reasonable distance, hence I have had to fall back on wired gigabit.

If you can hold down for some months, you are gonna get the wi-fi routers with 802.11ac (currently you have 802.11n). Its gonna be a 1.3Gbps speed. Almost all the vendors are running in the race to get the chipset from Broadcom.

Also look this Securifi, which is world's first wi-fi router and they have got a touchscreen in their router.
