I'm finding many routers are under control by the ISP and some are turning on firewalls. I'd check that.
I have a LG-47LM6700 Smart TV and I had SmartShare all set up and working a while ago but for some reason my TV can't see my computer anymore. I have not knowingly changed any settings and have tried to figure it out, which included calling LG, but have had no luck.
If anyone has any ideas on what's wrong and how to rectify it they would be greatly appreciated.
