Customer Reviews for Internet Service Providers in New Jersey
Customer Reviews
Alexander T.
Starlink Satellite
June 16, 2026 Starlink is a satellite internet service from SpaceX that’s great for people in rural or remote areas. It usually gives fast speeds around 100 to 250 Mbps and works well for things like streaming, video calls, and browsing. It does cost more to set up at first, and bad weather can sometimes affect the signal, but overall it’s a solid option if you don’t have access to cable or fiber internet.
A Wanaque, NJ Customer
Optimum Cable
June 06, 2026 Our internet provider does give us consistent service and high speeds. It's Optimum, and I am happy with that aspect of the company. They are also our cable company, and that aspect of the company has changed for the worse. Prices are climbing but we get poorer service. They are closing local stores and pushing cell phone plans on us instead of fixing our issues. So I have a mixed feeling about the company overall, but the internet service has been solid and reliable.

XFINITY Cable
May 13, 2026 Because Comcast is the only option for internet service unless I want to use a satellite provider, they seem to think they can get away with charging what they link. They refuse to allow existing customers to take advantage of new customer pricing. Their upload speeds are terrible, much slower than download speeds. If I had a viable alternative I would switch but unfortunately I am stuck with them.
