Wi-Fi on a cable or DSL line is not a problem. My issue is with using the mobile cell bandwidth for questionable items. If I break down on the side of the road and I cannot get voice due to overloading then I am rather upset. This is beginning to happen on the west side of Houston near I-10 on Verizon.
Anyone who puts a Wi-Fi router on a mobile cell line should have their favorite parts removed in the most painful manner possible.
