This is actually a really bad choice, unless you start using Realtek WiSoCs 
(RT30xx/RT28xx). RTL8186 and RTL8651B are using a Lexra core, which is famous 
for not having 4 patented instructions (lwl, lwr, swl and swr), which 
therefore requires a different toolchain. Also the Linux support is just non-
existent. Finally they use a brain-dead bootloader called ROME which only 
allows a couple of actions to be performed.

More seriously, buy a WRT160NL or WRT54GL from Linksys, which is equally cheap 
as those Realtek devices.

This is a much better choice :)
