Up until 2 weeks, WiFi was easy to hanle. Whereever I went, and a WiFi network was available, I asked password, and even after months of absence, returning to the same location, the Galaxy automatically switched from 4G to the local WiFi network and still had password in its mind.. very practically.
For uncertein reasons, today, my Galaxy recognizes the WiFi network easily, but askes me every time to enter the password again.. very enoying.. who nows about a possible setting or solution? Thans in advance. Guido
