@JoannaWang hi! Same issue here. Checked valid till 2019 April. My device stopped working since early August. I’ve tried to rest few times already still not working. Cannot browse Baidu neither. However, can log in to admin to change password and any other settings. So should not be the signal issue. Pls help tks!
