I have Windstream for internet and I don't have any complaints. I'm able to get up to 12Mbps but most people in my town are only able to get 6Mbps. Here at work I believe we only have 3Mbps and it works just fine.
Doing a little more digging on Windstream's DSL delivery in general, and their reputation looks relatively bad (although, as with everything else, those with problems are going to be doing the posting, not those who are happy with the service). DSL Reports has many Windstream reviews, and very few are compliementary.
BBB's website has this to say about Windstream:
According to BBB files, Windstream Communications, Inc. has a pattern of consumer complaints alleging slow or inferior Internet speeds. Consumers typically allege that the Internet speeds provided by Windstream are slower than those advertised by the company and that attempts to resolve Internet speed issues directly with the company are unsuccessful.
Windstream has responded to some complaints stating that it cannot guarantee error-free, uninterrupted service and that service performance will vary based on factors such as computer member, age of the computer, and Internet congestion. The company has responded to other complaints by stating that it is aware of Internet traffic issues in a consumer's area and that it is working diligently to resolve Internet speed issues by installing new equipment and system upgrades.
Windstream has responded to BBB request for a response to the allegations presented by consumers by explaining on-going upgrades that include a combination of network equipment supported by copper-fed and fiber-fed wires, depending on the location of the customer. In 2013, Windstream spent approximately $80M to upgrade and plans to upgrade approximately 85% of its customers.
Windstream states that in an effort to address the other 15% of their customers in copper-fed areas, they have applied for funding from the FCC for funds from Connect America Fund (CAF) and plans to match this funding to support projects for under-served areas to begin construction in early 2015.
Customers who will not benefit from upgrades will be given option of migrating to satellite broadband or Internet Access, which utilizes copper-fed areas. Internet Access is provisioned at 1Mbps, is an "AS-IS" services and is sold at a $7.50 discount.
BBB has seen a decrease in complaint volume since meeting with Windstream regarding these specific issues.
This is pretty worrisome. TWC has been pretty fast and dependable for these past 3 years, with a rare outage, and decent response to problems.
