Hallo,

users did encounter some strange problem where some websites cannot be loaded with their iPad whereas the same sites can be loaded with another device.

First of all, I would like to know if there are any serious problems inside the network.

You find attached a network trace of the router's wifi interface. I see some TCP Retransmission packets but I'm not sure if they indicate some serious problem.

My question is: at a first glance is there any indication for some serious wifi issues?

I would say too many Selective Acknowledgement packets. At least for a link between multiple public IP addresses.

Thanks. Could you give me a hint how to identify SACK packets? I searched for "sack" in the trace but I'm not quite sure how to identify those packets.
