I recently got the arris surfboard G34 WiFi cable modem. I have xfinity as my internet provider. I hooked everything up and was connected to internet and WiFi but was getting a very weak connection (about 8 mbps). So I unplugged and restarted the modem. Now it’s showing it is getting about 115 mbps but won’t connect or give WiFi. The modem just keeps blinking blue and green. Won’t go solid and connect like before. I did a reset as well and still won’t connect. I did a troubleshoot with xfinity but they want to send someone out because it’s not working but because it isn’t their device, if the arris device is faulty I will be charged. I’m not sure what to do to troubleshoot on my end or if my new modem is faulty. But it connected before so I’m unsure.
