Wireshark is a free network protocol analyser - it captures information about all network activity from your computer and can be used in diagnosing problems you may have with network performance, be it general or for a specific application.
Wireshark can be downloaded from here. Choose the file appropriate to your computer's operating system. Note that a Windows portable version is also available which can be installed on a USB key.
Wireshark was written by an international group of networking experts, and is open source software. Plusnet cannot be held liable for issues that arise from the download or use of the software.
If you think that a particular application is transferring data slowly or performance is not what should be expected, Wireshark can help determine that your data is being prioritised correctly.
The following information shows you how to interpret the data that has been captured by Wireshark.
C:\Documents and Settings\user>nslookup 126.96.36.199 Server: pth-cdns01.plus.net Address: 188.8.131.52 Name: mirror.ac.uk Address: 184.108.40.206 Aliases: 220.127.116.11.in-addr.arpa
C:\Documents and Settings\user>nslookup 18.104.22.168 Server: pth-cdns01.plus.net Address: 22.214.171.124 Name: unknown.ams.astraweb.com Address: 126.96.36.199
The following table shows the various queues and their corresponding hex values in descending priority order.
|Traffic Queue||Hex Value||Example|
|Titanium||0xa0||Gaming & VoIP|
|Gold||0x80 or 0x60||Interactive traffic|
|Bronze||0x20 or 0x00||Non-interactive traffic|
If you find that your traffic has been incorrectly prioritised you can supply us with the captured data so we can get this looked into.
Go to the Help Assistant and choose the path My Broadband Connection >> Incorrect Traffic Management. Include as much information on your problem as you can.
Click Add a file or screenshot, and then click browse. Find the file you want to attach. We are unable to investigate your Wireshark captures unless they are in the .pcap file format. Also please ensure you are uploaded the .pcap file compressed in a .zip file
