I've installed Ubuntu 14.04 LTS on my HP Chromebook 14. Unfortunately, I've been having some networking problems.

When I connect to the Internet, one of two things happen. Occasionally, the Internet works well. However, more often than not, I get page not loading error. No internet functions, yet I can access the router and local networks (Minecraft LAN worlds for one thing). I've tried with several different networks, some with better results than others. Anything I can try? Or additional information I can provide? Thanks in advance. Contents of wireless-info.txt (thanks wild-man):
