The WiFi is very limited on the TiDAL - you may need to be within a couple of metres of the access point to use it successfully. Best results are to stand next to an access point that isn't being heavily used. The one in the badge tent itself is good for this! The SSID emfcamp is preconfigured, and it won't make any difference switching to another - the problem is with the badge hardware itself. If you have changed the SSID, the credentials for the duration of EMF 2022 are SSID=emfcamp, username=badge, password=badge (WPA2 Enterprise).
Some people have reported more success by opening "Settings" and changing "WiFi TX power" to "2 dBM". You'll have to be really close to the access point, but that may reduce interference.
