If you live in Greater Los Angeles and are fed up with Time Warner Cable, there’s probably not much you can do about it (unless you’re the L.A. city attorney, in which case you can sue). The frequent outages, slow customer service and small number of high-definition channels are a fact of life. But the next time your Time Warner Internet goes down, wait a moment before you shout expletives at your modem. There may be a solution, albeit an unauthorized one.
