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.
