I decided to try Earthlink as I am at least average tech savvy and did not mind that they would…read morejust mail me a box with instructions on connecting. In any event, I saw they had a service guarantee.
I followed the install instructions to the letter, but no matter where I moved the device I still only received a blinking blue light, never a single green light showing some connectivity. I concluded that my apartment was not able to receive the signal from the tower. I then proceeded to call to cancel the service (unable to cancel on the app directly it seems, hmm). The customer service person was rude, talking over me multiple times until I called out their behavior and began talking over them. They insisted that I allow them to centrally activate my device. I told them I had no confidence in the service since I was not able to get a single green bar showing any sign of connectivity potential, and the fact that they can temporarily boost power to activate my device was not reassuring. I wanted to avoid an activated device that nevertheless could not receive the internet signal under normal conditions. I then cancelled the service over the phone, even as the representative admonished me for not letting them activate the device, and warned me that the $85 is nonrefundable. I then had to (successfully) dispute the charge, and got all my money back as the credit card company agreed that Earthlink did not provide the service they promised, and tried to not honor their guarantee. So a fair bit of time wasted, and if you cannot get a single green bar yourself I recommend you dispute the service like I did. Or better, try all other options first--to save yourself time and frustration dealing with indignant and self-righteous customer service representatives.
I hope this review saves you time and effort!
