I’ve had sumo fiber for over a year now and haven’t had any issues with it. I switched from comcast where I was paying $50/month for data over the 1tb cap and I was having to restart the modem daily or weekly due to network problems. With sumo, I haven’t ever had to restart my modem unless I restart my personal router for some reason.
The speed is fast, my wife and I cut cable 3 years ago and we have no problem streaming 2 roku’s and a computer or tablet along with phones all at the same time. I’m a 24/7 student and I have to have internet all the time, this is the best internet I’ve ever had. I highly recommend it to anyone who wants great internet!! With utopia and sumo, I’m paying 1/2 what I did for comcast.
