Über die WLAN-Funktionalität des Routers möchte ich mit dem iPhone ins Internet.
Ich habe sämtliche Kombinationen von Einstellungen, sowohl am Router als auch am Telefon ausprobiert. Das Ergebnis ist immer das Gleiche: Wenn eine Verbindung zu Stande kommt, dann äußerst instabil. Bedeutet: mal bekommt das iPhone eine passende IP, mal nicht. Dann kann es sein, daß das iPhone eine gültige IP (+ Einstellungen) bekommt, jedoch meinen die Anwendungen (apps), daß keine Verbindung zum Internet besteht.
Eine Auffälligkeit findet sich im (ungeschnittenen!) Log des Routers:

Hat jemand ähnliche Probleme? Was bedeutet "sending OFFER"? Und warum antwortet das iPhone nicht mit "ACK"?
