How do you check for slowness in Wireshark?
Go to Wireshark Statistics. Select the option TCP stream graph. Choose the Round Trip time graph to find out how long it takes for a file to download.
Why is Wireshark not capturing packets?
A problem you’ll likely run into is that Wireshark may not display any packets after starting a capture using your existing 802.11 client card, especially if running in Windows. The issue is that many of the 802.11 cards don’t support promiscuous mode.
