The disclosure relates to wireless networks, and more specifically to multiple access networks. This present disclosure provides for a method in a wireless device 10, for predicting Quality of Service of a possible future connection between the wireless device 10 and one or more wireless networks 30. The predicted Quality of Service may be used e.g. for making a handover decision. The disclosed method comprises detecting an access point 31 of a first wireless network within range 100 of the wireless device 10. The method further comprises determining the number of devices 11-13 already being connected to the access point and calculating the predicted Quality of Service based on the determined number of devices already being connected to the access point. The disclosure further relates to a wireless device 10 and to a computer program.
