Weak Wireless Signal

[the_hawk22]

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

eth0      no wireless extensions.


lo        no wireless extensions.
