Dear colleague.
Did you solve the problem which the handover time takes too long? I think that you shoul check your wireless bandwith becuase in my case handover time takes about 3-7 seconds normally. However, in your case, it was too long.
Also, when the network has high traffic, the handover time should be late. I am not sure this reply helps you.
Cheers.

Thank you very much Benjamin, it really helped me.
I haven't experienced the priorization of the interface connected directly to the home network to
the other, as you described, but for me it is much better without it, so I am satisfied :-).
The only problem I have now is that the handover between the interfaces takes too long (between 5
and 20 seconds). I have lessened the interval for Router Adverisements (1s Min, 3s Max), set the
MnRouterProbes to 0 (previously it was 1), but nothing helped. Do you have any other hints?
Regards,
Michal
