Recently I’ve been messing with my wifi card trying to connect to my wifi in Ubuntu server Precise LTS. I couldn't get it to connect so I uninstalled it and installed Trusty. It is a little laggy with all of the window effects but my biggest concern is the WiFi. It says that it is connected and ifconfig displays that its running just fine except that there is 203/412 received packets dropped. Every time I try to do anything online related, it gives errors like it has no connection at all. I can't update it with "sudo apt-get update" and Firefox says "Server not found" at start. Please help because this is my server computer and right now its being as useless as a 30-pound calculator.
