Internet Access at Michigan State Parks

Thank you all for your responses. It's starting to sound like it may be that I am using Apple products. My husband also has an iPhone and he's having the same problem that I am. For those of you that are getting a strong enough signal AND can use your phone as a hotspot to give your laptop internet access, please let me know what phone and what service provider you have.

Also, one post mentioned a Booster - what's that? Another question - would a mobile hotspot like one from Verizon work better than using a cell phone? Do they have a more reliable signal/better antenna?
