Armstrong is such a scummy company. Horrible wifi, horrible prices. I hope they go bankrupt.
Okay internet, base speed not nearly as fast as spectrum and much more expensive for the same speed. Data cap is a scam to get you to buy more services. Stupidly small approved modem list is borderline illegal by FCC rulings.
Yes, Armstrong is a smaller internet service provider (ISP). They may not be able to offer the same services as a bigger ISP like Spectrum. At least the modems listed on the Armstrong approved modem list are current modem models. A company like Blue Ridge has mostly older devices on their approved modem list.
