SSDP - Simple Service Discovery Protocol - can actually turn out to be a disservice, if this protocol acts in the way pictured to the left. As you can see from the Wireshark capture, SSDP is causing some unnecessary congestion in my LAN; in fact, it's not unusual for SSDP to broadcast about 10 frames every couple of minutes. That's annoying, and if it's causing the same problem for you, the following instructions may help stop this spam.
- In Windows: 'Start' > 'Run...' > type in 'services.msc' into the text-input field and press 'Enter'.
- Locate the redundantly named "SSDP Discovery Protocol" > right click > left click 'Properties'
- Under the 'General' tab, locate 'Startup type.' Select 'Disable,' then click 'Apply.'
- Locate "Universal Plug and Play" and repeat steps 2-3.
- If this solves your problem, good for you. If this doesn't solve your problem, proceed to step 6.
- Type your private default gateway address* into the address bar of your internet browser.
- Submit user name & password to login into your router [for the purpose of this Howto, a Linksys will be used].
- Go to the 'Password tab' and identify 'UPnP Services.' Check 'Disable,' then select 'Apply.'
- Logout of the router, or close your browser tab and clear the cookies from this session.
* private default gateway can be found by:
a) 'Start' > 'Run...' > type 'cmd' > press 'Enter'
b) Type 'ipconfig' into the command prompt > press 'Enter'
c) Locate the ip address after 'Default Gateway:'
