As per original post this also affects 5Ghz wifi
DFS uses part of the 5Ghz frequency. If I am not mistaken China does not allow wifi use in part of the DFS spectrum channel (96-144) so if you set your 5Ghz wifi to those frequencies, your tablet if it is the Chinese market device will not connect to those WiFi Channels. If you bought a global or international version I don't think you would face this issue.
😮 thanks for sharing more details - much appreciated.
