Can't browse network with Wifi with 5057 while xv6800 was power on

[bmb2n]

I flashed my xv6800 with 5067 kitchen for a few weeks now. Everything works better except the network browsing with Wifi. Turning on Wifi while the phone was on can surf the internet but can not browse the network neighbor hood. I have tried both network plugin andd Resco Explorer with the same error "no network computer found".

If I left the Wifi switch on and soft reset my phone, everything woks fine as normal. Browsing the internet and network drive mapping work as expected. However, If I switch the Wifi off and on again, the network mapped drive would fail to work.
