SuperWifi stopped working after vacuum cleaning

Hi, I have an issue with my super wifi. Our apartment is not big but still the modem was noch reaching everywhere. Then we bought 2 superwifi spots and when we installed them the first time, all went well but as soon as we started vacuum cleaning the signal got lost for some reason. We reset them and one of them worked again but lost quickly the signal again. Since then both spots are showing and orange signal and I retried to reset it several times and connected it back to the modem without success. I would need help to get them installed!
