MacBook Pro 9.2 Ubuntu 14.04 Full Link Quality Wireless Error

[ricardo32]

Hey guys I am using Ubuntu 14.04 on my mac, After being on the wifi for around 5 to 10 mins it randomly shows the signal as being maxed but the internet stops working all together. Here is what it shows when my wifi is working:

wlan0     IEEE 802.11abg  ESSID:"vodafone-15B3"
      Mode:Managed  Frequency:2.417 GHz  Access Point: 08:7A:4C:EF:15:C4
      Bit Rate=144 Mb/s   Tx-Power=200 dBm
      Retry  long limit:7   RTS thr:off   Fragment thr:off

      Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
      Tx excessive retries:0  Invalid misc:0   Missed beacon:0 

And here it is when it happens:

wlan0     IEEE 802.11abg  ESSID:"vodafone-15B3"
      Mode:Managed  Frequency:2.417 GHz  Access Point: 08:7A:4C:EF:15:C4

I have installed the following drivers:
