Ain't never had the Service providers do the inside of my house.
Then again? I was THE FIRST ISP in my area. Yeah way back in the days of Dial Up internet. PRE-56K! Sold the crap outta internet access in those early days!
Any customer had a problem? I was the Guy that went and fixed it.
Now I have a Cable feed at 400Mbps. Own my own Router that handles 2.4 GHz and 5 GHz Wi-Fi. Wi-Fi covers my whole house and over 30 yards around us!
