Wirless not loading

[Prevs]

I was having a problem with my wireless connection where it would drop out unexpectedly and especially after rebooting the router. A bit of googling told me to update the firmware since then there hasnt been any problems with it dropping out. Their is a different problem know because the wireless doesnt boot when I login. I have to run a repair because Iv'e got ssid sending off. Once i have connected ive got know problems though. Does anyone know why this is happening ?
