Windstream is okay. Better customer service and price than Spectrum. They make you use their modem, but the price was included. It required a phone jack which is an inconvenience for some. The range on the Wi-Fi is poor, basically about 500 sq. feet. The wireless speed near the modem or with an ethernet cable is good. No issues at all with the DVR or viewing experience though. I paid around $90/month for the second tier of their internet and the sports version of their cable package.
That being said, if you're looking for a change, I would recommend Allo internet with Hulu Live, that's the best bang for your buck/service combination I've found.
