Frontier DSL
March 25, 2023 Frontier does not produce when it comes to what it promises. The DSL speeds are not very fast. It's the same with the upload speeds. Also, the customer service is very lacking. That is if you can ever talk to someone. I wish I wasn't locked into my contract, because I would definitely move to another provider.

Cox Cable
January 19, 2023 Cox Cable offers decent service at best. Outages can be irregular and stutters or lag spikes are common. Pricing is decent but only because our plan being upgraded to unlimited data because of less than advertised speeds. The one positive I can think of is that you can use your own modem.
