In our rented unit here, we have Frontier DSL. Terrible. half the time, we can't get on or the green modem light goes out and we lose our connection. Mention Frontier down here and everybody makes a face. They took over from Verizon and things went downhill from there. Repairman comes next Friday. I need this service for my job and can't abide the dropped Internet every day. I could see problems with wifi, but with an Ethernet cable, we never had any problem in the 6 years we rented here until this winter.
