I switched from Comcast to WOW and dropped my TV and phone to just internet, The 1Gig tier $80 per month, but I could never realize more than 460 Mbps. They came out about 4 times, shuffled their feet, climbed some ladders, nothing changed on my end so I downgraded to their 500/25 tier. I'm paying about $50 per month with all the fees for just the internet. I was paying Comcast $290 per month for TV, Internet 350/25, & Phone. They can have it and choke on it.
I'll run a test soon when I'm home.
