X8 WIFI ISSUES help

Wondering can you help me! I have a Eufy X8 and its amazing, as a dog owner I love it! Today for an unknown reason the wifi has become disconnected. I have tried all the router related trouble shooting recommended on the Eufy website, I have reset it and nothing is working. I also tried to add a new device and the temp Eufy wifi link does not appear in my wifi options which leads me to believe that the wifi connector is faulty somehow. Any advice? thanks in advance Ingrid
