problem
When I connected to my logic K480 bluetooth keyboard, the Network speed became obliously slow!
reason
After refer a title about bluetooth and wifi signal would be conflicted, I realize they are in same frequency at 2.4GHz!
solve
Login Router Administration according local IP address.
Find out frequency setting.
Turn 40M to 20M.
(while turn it down, the Network speed would be slow than before, but more stable)
Done!
