I have no idea how to check what type of adapter my router supports. Any idea what format that is in which would tell you? Also how can I tell what a dual-band and single-band is? I'll be streaming videos, downloading a good amount of things, gaming, and work.
Dual band means the card can use lets say 2.4GHz AND 5GHz(many use both at the same time, some older ones used one or the other).
MIMO(what gives you all this extra speed many times) means the router and card will use more than 1 channel at a time so they can use all available channels(when it came out it was said to hurt other users wireless performance because it was using all the channels). Either way, as long as router and PC have multiple send and receive antennas and have the right firmware(think of it as the routers OS), this improves speeds quite a bit.
2.4GHz has LOTS more interference because it is used for everything an microwaves just happen to run in that frequency meaning making popcorn can cause your streaming moves to skip(on the internet, buffering should reduce this quite a bit).
