Bridging Modem

I've been having wi-fi problems where my connection would drop frequently and I had people telling me that it's CenturyLink's manufacturing that doesn't support wi-fi really well at all. So in hopes of resolving this for a better, stronger connection, I wanted to try one of the solutions which would to be bridging the networks. I'm still very new this, even when the problem confronted me I had to learn it.

As soon as the page finishes applying the "Transparent Bridging" it says that I have no internet access. I need to configure it's setting, but I'm not really sure how.
