Century link router

My doorbell ( 2nd generation) stopped working, though it was broken, since it received a hard blow. Bought a new one ( battery powered plus), and had the same issue with the installation. Is not connecting to my WiFi. After going through all the troubleshooting offered online, called the support number, after they made me repeat the same steps, they asked me what router I have, informed that is the latest one of century link, then they informed that is a issue they are aware of, and contact the internet provider, ask them to disable part of the security of the router ( leave the WiFi open without password…) , and try again. Still not working. Called again, and they informed that is a knows issue, again, and the engineers are working on the problem, and I would be contacted. Has been a week since that phone call, 3 since I saw the old one stopped working, and waiting for the new one. Still not doorbell working…
