Wireless networking issues .... upgrade from 12.04 to 14.04

[verber001]

My wireless radio keeps disconnecting so much so now....that I can even search at all on the net. I ran iwconfig and got:

eth0 no wireless extensions.


lo no wireless extensions.


wlan0 IEEE 802.11bgn ESSIDff/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr=2347 B Fragment thrff
Encryption keyff
Power Managementff

Power management is off which I´ve seen others say was the problem. But I see no access point associated. Not sure if this is the problem or not. Can anyone help me out?
