The reason is probably a poor antenna. WIFI is the bottleneck, the
processor is running at ~ 30%

I am thinking in the same direction. A combination of an OpenWRT router
and a MK802. The best way to do this is by using the USB-OTG port. If
this port is put in device-mode you can load the Ethernet-gadget kernel
driver. This driver turns the MK802 USB-OTG port into an USB-Ethernet
device. If you then connect the MK802 to the USB port of an OpenWRT
router it will be detected as an Ethernet interface.
Apart from the higher speed there is another benefit. The USB port of
the router can most likely power the MK802. (I have successfully ran the
MK802 from USB power alone). Note: power consumption will probably be
much lower with WIFI and graphics-core turned off.
I have tried to get the USB-OTG port working but failed. The problem
seems to me that it is not yet supported by the kernel. The function
that should do the switching between host<->device mode is empty.
Understandable because the kernel is generic, and not all A10 devices

I have no idea. Ask your question in the forums i mention in my article.
I'm sure more people want the same as you do.
