I've had FIOS pretty much since they stalked the neighborhood with sales people (close to 2yrs now).
A couple of weeks back my internet didn't work anymore; this coincided with me hooking up my new ps3. I had the fios router connected to a wireless router and all my consoles/pc/laptops connected to the wireless router. The tech who came out said that I no longer needed to use the wireless router as Verizon&Xbox fixed their connectivity issues. I removed the wireless router, connected everything to the fios router and everything worked great for about 2 weeks.
Yesterday, I had no internet connection at all but the connectivity light was green, not amber. I reset the router, I unplugged the router power cable from a power strip and plugged right into the wall; still no luck. I had a tech on site last nite from 7pm-9pm. He replaced my router, replaced the splitter in the basement, replaced the box outside on my house but still no internet (except Google would come up but you couldn't do any searches or go anywhere else). He threw his hands up and said he did all he could do for me and that he would have to escalate to higher support.
He was talking to the "network" people and they are suppose to look into this today. They couldn't do anymore for me last night as their department was closing at 9pm. He told them that I was cancelling the service today and going back to comcast (where I never had a Internet issue) if it was not resolved today.
My wife is a work from home SEO contractor. Every hour we have no internet, we are losing money. Maybe someone at Verizon will read this and try to assist??
