Wifi network not showing up on laptop but showing up on phone

I have an open WiFi network that I use in my apartment (provided by my realtor). The network shows up on my phone's WiFi and works smoothly but doesn't show up on my laptop. I have Windows 7 and Linux Mint 16 installed on my laptop and the WiFi network doesn't show up on either. However, the WiFi network does show up on my roommate's Macbook Air.

Could this be a problem with my WiFi network card? Or could it be related to something else? I'm not really sure what to Google so I thought I'd post here.


A possible problem as that your phone and your friend's MacBook can access 5GHz networks, while your laptop, which sounds quite old, only can access 2.4GHz networks. Possible solutions are:

  1. Get a new computer
  2. Get a external wireless card that supports 5GHz networks.

Probably time to get an upgrade.
