Using Wireshark to Troubleshoot Network Connectivity Issues: Follow TCP Stream
One of the most useful features in Wireshark is the “Follow TCP Stream” feature, which allows you to view the full conversation between two devices as a single stream of data. This can be especially helpful when trying to troubleshoot connectivity issues, as it allows you to see the entire exchange of packets between the devices, rather than just individual packets.
To use the “Follow TCP Stream” feature, first select the packet in the packet list that you want to start the stream with. Then, right-click on the packet and select “Follow TCP Stream” from the context menu. This will open a new window showing the full conversation between the two devices as a single stream of data.
You can use the “Follow TCP Stream” feature to identify any problems with the exchange of packets between the devices. For example, if you see a large number of retransmissions or errors in the stream, it could indicate a problem with the connection. You can also use the “Follow TCP Stream” feature to see if any packets are being dropped or blocked, which can also cause connectivity issues.
