Who we are ?

Bertram Internet provides dependable, high-speed internet service to underserved communities across Wisconsin since 2003. Headquartered in Random Lake, Wisconsin, we are dedicated to connecting small town communities like ours. We are proud to home our entire staff locally in Wisconsin.

What we do ?

Bertram is not your typical ISP. We specialize in connecting smaller, rural communities many carriers overlook. We connect these locations using innovative wireless technology. We have been pioneers in the industry since the early 2000’s, and we are constantly expanding our network to reach more communities.

Where did we Start?

Bertram Internet was founded in 2005 in Random Lake, Wisconsin by local entrepreneur, Jim Bertram.  Jim, an Adell native, was disappointed with the lack of reliable internet service for his community. He decided to take matters into his own hands, and Bertram Internet was created.

Our Mission

Our mission is to provide our fellow Wisconsin citizens with dependable, high-speed Internet access, in areas our competition is unable to service reliably. With technology advancing at a breathtaking pace, we are dedicated to making sure that no one is left behind and out of touch with the world around them. Using state-of-the-art Point-to-Multipoint technology, we have the capacity and expertise to establish wireless internet access throughout the state, especially in underserved and remote locations where cable and DSL are not available.

We have worked in the industry since the early 2000s and have provided Internet service since 2005. During that time, we had the foresight to build with the future in mind being fully prepared for anticipated growth.
