Backup internet options in Knoxville

Home 5G and fixed-wireless plans from T-Mobile Home Internet (84%) and Verizon (80%) report coverage of Knoxville homes (Verizon’s figure combines Fios fiber and 5G Home). They run over cell towers rather than cable or fiber, so they can work when a wired network is down. Cell coverage by area is 100% for 4G LTE and 98.2% for 5G.
About 13.3% of Knoxville households, roughly 11,500 homes, get online only through a cell plan. For them a mobile outage is an internet outage.
Power and weather behind internet outages in Knoxville
Knoxville Utilities Board (KUB) customers averaged 352 minutes without power in 2024, across 1.86 interruptions each, against 279 minutes for Tennessee as a whole. Cable nodes and fiber cabinets run on batteries that last hours, not days, so a long power cut can take internet down even for homes whose own power has returned. See Knoxville power outages when both go out together.
Knox County logged 317 storm reports since 2015, most often thunderstorm wind, flash flood, and hail. Reports peak in July. Power outages were named in 7 of those storm episodes. Wind, ice and flooding damage poles and buried lines, which is how a storm turns into an internet outage as well as a power outage.
Fiber reports reach 97.9% of Knoxville homes, cable 98.9% and copper lines 67.3%. Where fiber runs to the home, a red or blinking LOS light on the optical terminal points to a line problem that a restart will not fix.
