I keep losing connection when playing League of Legends!

Whenever I play league of legends, there is a chance that I lose connectivity and/or my ping jumps to over 300!
This happens on a wireless connection and my ISP is charter. All I can do is wait for my connection to come back up, and I lose whatever game I'm playing at the moment. I'm sorry if im not being very specific I'm not sure what information is needed. I posted my ipconfig below.

Hard to say what's going on there, but I will always recommend that people choose wired connections over wireless if at all possible. They are more reliable and secure and less susceptible to interference. Are you able to view the other networks in your area, with a tool like INSSIDER? If you are overlapping with alot of other networks you can change your channel in an attempt to get a better connection. Other factors can be at play here such as microwaves and vacuums etc. Maybe play on wired for a few days and if it's still shaky, contact your ISP.
