I agree with Particle as it has been my interpereted experience of friends as well as through research on the internet:
Link to fastest wifi I could findAside from that, it is not realistically possible to send 400MB per second over any wifi connection that a consumer can purchase.
Advertisers are not the brightest in the field and will easily slap a capital "B" on something with out thinking twice about it, thus making it seem like the connection is better than it really is... and i will illustrate this:
General info for whoever is interested:
b = bit = 1 bit
linkB = Byte = 8 bits
K = Kilo = 1024
M = Mega = 1024 Kb
Justification:
8 Mb = 1b x 1024K x 1024M = 1048576 bits
8 MB = 8b (which is 1B) x 1024K x 1024M = 8388608 bits
The difference in connection speed is:
8388608b - 1048576b = 7340032b
In other words:
1 Mb is 1/8 the speed of 1 MB.
So the router with a maximum wifi transfer of 108Mb only has a MB transfer maximum of:
13.5MB13.5 MB = (13824B /1024M)
Which is reduced from:
13824 KiloBytes = (1415576B / 1024K)
Which is reduced from:
14155776 Bytes = (113246208b / 8b)
Which is reduced from:
113246208 bits = (108b x 1024K x 1024M)
Mathematically there is no possible way to achieve 400MB over wifi available to consumers... and on top of that, there is no firmware (open source or proprietary) that supports speeds that fast either.
