When it comes to satisfying its customers, Mediacom falls short. The American Consumer Satisfaction Index rated it 56/100, and it only managed to rank in the West region with 2/5 from J.D. Power, the lowest publishable score. Mediacom complaints typically consist of unresolved issues, frequent outages, and double billing.
In most cities, Mediacom promotes TV and internet service starting at just $40 per month, a bundle that unlocks 100+ channels and 60 Mbps of speed. While it seems like an excellent deal, it won't be reflected on your bill: You'll be responsible for a $10 modem rental fee and a $10 local station surcharge each month, plus a one-time $10 activation fee and $100 installation fee.
Across all types of internet, Mediacom provides fairly average reliability to customers. In 2016, the Federal Communications Commission reported on the performance and reliability of internet providers, including how often their subscribers receive advertised speeds. Mediacom provided advertised speeds about 80% percent of the time. That's better than Cox, which does so 75% of the time — but it pales in comparison to Comcast, which achieves its advertised speeds just over 90% of the time.
