Home 5G and fixed-wireless plans from Verizon (92%) and T-Mobile Home Internet (89%) report coverage of Wilmington homes (Verizon’s figure combines Fios fiber and 5G Home).

Power and weather behind internet outages in Wilmington
Delmarva Power customers averaged 127 minutes without power in 2024, across 0.77 interruptions each, against 116 minutes for Delaware 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 Wilmington power outages when both go out together.
New Castle County logged 388 storm reports since 2015, most often thunderstorm wind, flash flood, and flood. Reports peak in June. Power outages were named in 26 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 59.2% of Wilmington homes, cable 99.9% and copper lines 0%. 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.
