I wasn't able to get Xfinity to install this, gifted to me, modem Arros SB6190 which my friend had it working and installed with Xfinity in Texas ( I saw it working).
The Miami, FL Xfinity rep says signal is good on their side but I cannot get the Up stream light to turn steady blue, as required.
Can't navigate internet, please see attached screen response. Also a picture of how the modem lights look with this problem.
Any assistance will be greatly apprciated.Arris SB6190No Bonded Upstream
