I did an update on my Fairphone 2. After the update I can not get a connection to my 5GHz-WLAN. I deleted the connection and created it again, but no success. I can receive the 5GHz ID, put in the password, but I will not get a working connection. 2.4 GHz-WLAN is okay.
Before I did the update, I only used the 5GHz-WLAN successfully.
I can’t believe it ! My device this morning is working on 5GHz-WLAN too !
During the night I switched it off and on, deleted and created the connection without success. Maybe, my fritzbox changed the channel over night. I’ll have an eye on it, the next days.
