Make sure your Wi-Fi is working properly by using another device connected to your Wi-Fi network.
Check whether you have correctly remembered and entered your own Wi-Fi network password when connecting the AeroCount particulate matter detector to your Wi-Fi network. (For example, by forgetting the network on your computer/laptop/phone/tablet and reconnecting to your Wi-Fi network.)
Restarting the modem may fix this problem as well. Additionally, some people have more success by using a laptop rather than a mobile phone. Follow the next steps to restart your modem (source):
- Unplug the power and Ethernet cables from the modem. Some modems have backup batteries that need to be removed too.
- Wait 2-3 minutes for the modem to fully power off. All the lights on the modem should be off.
- Reconnect the power and Ethernet cables to the modem.
- Wait for the Internet light to turn solid, then check if the internet is working properly.
