Almost a complete newb here. After my last upgrade from 12.04 to 13.10 my wifi now randomly drops. The only way I can get a signal back is a shutdown and restart otherwise it shows no network is even available to connect to. Had no problems until the upgrade. Any help would be appreciated.

I apologize for my newbness. I hope this is enough info for the hardware. Thanks Bruno for pointing out I needed to add more info. If I am lacking anything else please let me know and I'll post it.
