The Ranger cannot increase speed of existing source. It can only help pull whatever service is out there a bit stronger to you. Most campgrounds have tons of people drawing from the system and they also cut back speeds the more you use it. It keeps people from streaming TV and downloading movies on their system. for emails, they (CG's) are OK...for good internet speeds...worthless.
