Did you try moving the two devices really close to each other for a 
test? If the antenna is the only problem, WiFi throughput should improve 
a lot. However, I would not be surprised, if throughput stays the same. 
In which case it would be interesting to find out what else is 
contributing to the bad performance. I don't think it is the CPU.

Interesting idea. In other words, the MK802 _does_ have Ethernet :-)
I would still prefer to run OpenWRT + Freedombox on one and the same 
device. Just saying.
