Personally no I am not too concerned.
spreading gloom and doom helps no one.
if the Verizon routers need updates don’t you think Verizon would have pushed out an update? What purpose would it serve to leave the routers vulnerable when it would cause more harm to their bottom line. Customers equal MONEY and Verizon does not like to lose money.
until Verizon states their are issues with their routers or network, these doom posts just make individuals are worried for no good reason.
more important things to worry about. Like world peace or healthcare or lowering the prices of prescription drugs. A router is not that a major concern.
