No Internet after mutlicast broadcast to etherdongle

[Nightowlz1966]

I am running LSP newest version Updated on Saturday, on my HP Laptop.
I can load LSP and work on the internet at the same time, until I right click
and test a controller output. Once the lightbulb for output comes on and I
broadcast a test to my etherdongle with LSP output set for wireless network
connection my wireless adapter tells me I no longer have internet access and
I don't.    Any suggestions

If you only have one NIC card in your computer, buy a cheap USB to ethernet cable (~$20), and re-route all the communication coming out of LSP to the new network (redo the configure output in LSP sequencer *and* scheduler). That will take care of that problem.

Thanks for the info.
But how come using xlights or vixen to test with I can still access the internet while broadcasting mutlicast?

LSP has some issues...

The reason is most likely the frequency with which the data is being sent.  When you turn on LSP output, LSP sends the data at the full data rate to the etherdongle multicast address.  Your router is most likely trying to forward this out to the interwebs.  With other applications (be xlights / vixen, etc.) the frame rate may not be spamming 0 data packets as often.  It APPEARS (and I'm not a programmer, but based on packet captures) that LSP is sending the full set of universe data with 0s when you enable the output.  With xlights, I know xlights only sends data as needed - as changes occur, plus a packet once or twice per second. 

I'd guess you're saturating your upstream bandwidth with multicast in your current configuration.

The recommendation below does address the issue.  You also may be able to set your router to block outbound multicast data.
