Wireless keeps on disconnecting

[Reborns]

Hi guys

ok this is abit weird
i already called Applecare.. their solution doesnt work at all

i turned on my MBP-r
it will auto connect to my WIFI
i will surf internet ... less than 1 min.. it will self disconnect
i will open the Network Preferences
drop down the network.. select my WIFI
connect,,,, immediately auto disconnect
i will have do this like 3-4 times
then it will stay connected forever until i shutdown

i am using my computer on clamshell mode... but non clamshell also same issue

i have done this as suggested by Apple Support
reset my PRAM
reset my SMC
....

what should i do now?
i know my WIFI is working fine because
all my other devices didnt get disconnect
and i do not have this problem until the last update which apparently update the BIOS.... :O

turn off wifi, go to system preferences > network, click on wifi then advanced in the bottom right, go to Wifi Networks, remove your home wifi from the list.

then open up Keychain Access, look for your wifi name (it should show Airport Network pwd as kind) and delete it. restart computer and try connecting to the wifi again.
