The root cause is MK908 has a ill built-in antenna, which is no better than trash. I remove the case and connect a cheap antenna to the pin on PCB. Then i found the fix act like a charm, wifi problem all gone. The speed test shows MK908 now has the same connection speed as my NB.
Many people feel upset about MK908, i think you should. FW update can hardly solve this connection issue, consider a real antenna.
