Home 5G and fixed-wireless plans from T-Mobile Home Internet (68%) and Verizon (57%) report coverage of Casper 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 99.2% for 5G.

Power and weather behind internet outages in Casper
Rocky Mountain Power customers averaged 92 minutes without power in 2024, across 0.86 interruptions each, against 138 minutes for Wyoming 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 Casper power outages when both go out together.
Natrona County logged 129 storm reports since 2015, most often thunderstorm wind, hail, and flash flood. Reports peak in June. Power outages were named in 9 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 82.8% of Casper homes, cable 92.4% and copper lines 87.7%. 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.
