In some cases, you may find yourself in an area where traditional Wi-Fi is unavailable, unreliable, or insufficiently secure for your needs. A WiFi router with a built-in LTE modem, which utilizes a SIM card for mobile data, can provide a stable and secure internet connection for Atmocube. As an example, take a look at:
TP-Link Archer MR400 AC1350 Dual Band WiFi Router with 4G LTE, available on Amazon: TP-LINK Archer MR400
This router offers a reliable solution by converting LTE (4G) mobile connections into a private Wi-Fi network, to which you can connect your Atmocube. Please make sure to use a 2.4 GHz Wi-Fi network; 2.4 GHz networks cover longer distances and Atmocube does not connect to 5 GHz Wi-Fi networks.
1. Choose a data plan from a mobile carrier that offers good coverage in your area of interest.
! Data Charges ! : Be mindful of the data plan associated with your SIM card. Ensure it provides sufficient data allowance for Atmocube's needs: average data usage is about 0.25 MB/day. In addition to this, occasional OTA updates can use up to 1.5–2 MB per update: Data and Storage FAQ
2. You may want to double-check that the SIM card has internet access by placing it on your smartphone first.
3. Insert the activated SIM card into the LTE router.
Depending on the router, it may or may not require additional setup. The example router, the TP-LINK Archer MR400, is plug-and-play: just insert a SIM card and you're done.
For a different router, follow the router setup guide to configure the router. This typically involves connecting it to a power source and accessing the router's web interface via a browser or mobile app
Once the LTE router is set up and broadcasting a Wi-Fi signal, configure your Atmocube to connect to this network. Steps in this support article: Wi-Fi Setup via Mobile App
