I have a very weak 1 bar wireless signal. The same laptop has a strong wireless signal in Windows 8. Other laptops and phones in the exact same location will also have a strong wireless signal.
For the above reason, I'm pretty sure it's Ubuntu-related with the wireless driver, but not sure how to proceed.
Here is the output of iwconfig. Would appreciate any help getting this fixed. Roommates named our network CIA
