Internet?
Ich habe mit einem.nachbar vereinbart dass wir die Kosten des internet teilen – der hat mir dann die daten und das passwort gegeben – ich kann mich aber nicht anmelden da im Netz die Verbindung nicht angezeigt wird – es ist verschlüsselt – weiss jemand Rat?
Perhaps the reception is not enough to you
it can also be that, the network is just camouflaged and has no SSD entry.
Use the free Android app Fritz App WLAN and check where the WLAN signal is still strong enough in your apartment. Because Wi-Fi has a range of roughly 20-35m, and if thick walls are in between, the range is even lower.
Find a place where the Wi-Fi reception is still reasonably good, and there place a WLAN repeater that can supply the rest of your apartment.

If a smartphone does not display Wi-Fi, but your other device (PC, laptop, ???) does not, then it can not support Wi-Fi channels (often the upper channels 12,13,14 or > 50 cannot be used for the US market).
Good luck!
