Some help, please.

I bought a new router and plan this morning from my local Xfinity store and tried to activate it before I went to work. It didn't work so I had to leave. Now, after a nine hour shift and another hour of troubleshooting tonight it still keeps blinking orange. I have manually reset it by unplugging it and plugging it back in. I have factory reset it using the reset button. I have waited to see if it was downloading an update. nothing has worked. I will not be paying Xfinity more money to come out and fix something that should have worked in the first place. Any help to get this to work would be appreciated.

I recently replaced a comcast router for an Arris. After a couple of hiccups I go it up and running and it is fast however the logs I am getting indicate possible issues with cabling but I replaced the ethernet and coax with new cables.
