I cannot see my network's SSID (name) on the device screen a) The first step here would be to refresh the page with available networks several times and going through all the pages - the scan sometimes does not capture every wifi network, especially in a location where there may be many other networks interfering. We have also seen a very small number of cases where the network's SSID showed up on its own after a few hours. b) If this doesn't help, make sure your router doesn't auto-switch between bands with the same SSID and ideally create separate SSIDs for 2.4 GHz and 5 Ghz. If that's a pain, you can configure a 2.4 GHz guest network with an alternate SSID (you can find how to do both of these in your router's manual). c) If the network you're trying to connect to is on the correct 2.4 GHz band but you still cannot see it, try power cycling the device (just unplug it and plug it back again) and then unplug your router, leave it off for 1 minute and plug it back in. When your router comes back alive, refresh the list of available networks on your Lattice1 and you should see it.
I can see my network's SSID but I cannot connect to it - device says "Unable to connect" a) Okay, let's check if you can connect to another network to make sure the problem is not with the Lattice1's WiFi module. Please create a 2.4 GHz mobile hotspot and try connecting to it. If you can connect to your hotspot, the problem is most likely with your network's configuration. Also, try to connect via Ethernet and see if you can get online this way or not. If you cannot connect to the hotspot you created, please create a ticket and we'll have a look at what's going on. Give us as many details as possible! b) Once you have confirmed that you can connect to a different 2.4 GHz, it's time to check your router settings and look for the encryption type your router is using. The Lattice1 supports WEP, WPA/PSK and WPA2/PSK2, so switch to either of these if the encryption type is something else. c) We have also seen one outlier case where shortening the WiFi password to <31 characters resolved the connectivity issues. d) The steps above will resolve 99% of WiFi connectivity issues we have seen.
I can see the SSID, my router uses the correct encryption type, I have a reasonably long WiFi password, I can connect to a hotspot and via Ethernet but I still see the "Unable to connect" error when connecting to my WiFi network We would recommend you contact a networking expert at this point. The different configuration possibilities are almost endless and can be different with every router manufacturer and model. You can connect the device via Ethernet, if that doesn't work for you (e.g. your router is in another room), you can get a WiFi2Ethernet adapter such as this one.
