I'm having some issues with my wireless connection.

I'm using Ubuntu 12.04:

$ cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=12.04
DISTRIB_CODENAME=precise
DISTRIB_DESCRIPTION="Ubuntu 12.04.5 LTS"

Kernel Version:

$ uname -a
Linux dtabar-laptop 3.13.0-49-generic #81~precise1-Ubuntu SMP Wed Mar 25 16:32:15 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

The issue is with the bit rate, it's stuck between 1Mb/s and 6 Mb/s as you can see:

$ iwconfig 
wlan0     IEEE 802.11abgn  ESSID:"NewSocrates"  
          Mode:Managed  Frequency:2.462 GHz  Access Point: E8:DE:27:42:35:82   
      Bit Rate=6 Mb/s   Tx-Power=15 dBm   
      Retry  long limit:7   RTS thr:off   Fragment thr:off
      Power Management:off
      Link Quality=70/70  Signal level=-37 dBm  
      Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
      Tx excessive retries:0  Invalid misc:116   Missed beacon:0

sudo lshw -class network output:

Anything I'm missing? Any ideas of what may be causing this?

Thanks!

It seems from the output of the wireless debugging script that your WiFi is sharing channel 11 with 6 other WiFi networks close to you.

Please go to your router and change the channel to 2 (currently unused by any of the WiFi networks around you). That will improve your throughput.
