For Float to work you will require a strong wifi signal in the area that it will be used.

• Recommended WiFi settings

  Some WiFi settings might not work well with the Float. When experiencing trouble when connecting the Float to your WiFi, please change your router’s WiFi settings to:Security

  • Disable WPA3
  • Use WPA or WPA2 Personal, NOT WPA2 Enterprise!
  • Max password length: 30 characters! Longer passwords will NOT work!

  Encryption

  • WEP, TKIP or AES

  Main router settings

  • Enable DHCP
  • Use 2.4 GHz band, 5 GHz band NOT supported!
  • Use WiFi channels 1, 6 or 11, do NOT use ‘Auto’
  • Channel width 20/40 Mhz or auto
  • Enable 802.11 b/g/n mode or Legacy mode. Do NOT use ‘Auto’ or ‘802.11n’ mode

  If you still experience any issues:

  • Assign a static IP for your Float via DHCP settings.
    Firmware versions lower than ‘20210315’ show the Float’s MAC address in the ‘Maintenance menu’
  • Try using a WiFi name (SSID) with no spaces and special characters. The same goes for your password
  • Test if a basic WiFi setup does work, so no mesh routers etc. Try setting you modem as also the wifi acces point, and have the modem handle DHCP.
  • Try creating a hotspot with another mobile device. If the Float is able to connect to that, you likely still have wrong WiFi settings.
