Past 1-2 months wifi keeps dropping

[xbipin]

i have noticed from past 2 months or so all my devices drop wifi connection after some while but quickly connects again, initially i though it was my device as i recently got a nexus 10 and it had this wifi drop issue and it was only noticeable when transferring large files from lan to wifi and the other way round. later i realized when connecting to other wifi routers it wasn't there and this makes me suspect its the pfsense wifi only and also the sync softwares i use on the device, i reported the same to the developer and later based on logcats etc it was concluded that pfsense was dropping the wifi connection and not the device or the sync software
