Of all ISPs in Blacksburg, NTC has recieved by far the most complaints based on online reviews, word-of-mouth, and rankings at the [[w:Better Business Bureau|Better Business Bureau]]. NTC's packet shaping has led to many residents experiencing sub-100Kbps download and upload speeds when they are paying for speeds of at least 5 Mbps. Some students have described the value, customer service, and speeds experienced as "literally worse than [[w:Alolf Hitler|Hitler]]". NTC formerly required tenants to pay per-device, and was rumored to bill extra if it detected users had a router or if multiple people were sharing a single connection. NTC has also been criticized for anti-competitive practices in which they force landlords to enter into exclusive contracts which prevent other ISPs from offering service to residents. During installation of NTC's Ethernet wiring, the technicians cut the existing coaxial cables in several locations, thus rendering it completely unusable.
