When I initially got my UM 175 Verizon mobile broadband service, it was adequate. It was not super fast where I live but I was able to utilize the internet. Now, it is terrible! I can rarely connect and when I am able to connect, I rarely have more than one bar and I am disconnected after a few minutes. Are there any downloads to help improve service? Are there any free upgrades? Is there any software FREE that will improve service????
