Is it safe to enable UPnP on my wireless router?

I have noticed when I enable it on my router running ddwrt the quality of my audio/video streams really improve. I use Roku/ Sonos.

I called tech support for my ISP and was told since my network is password protected I am ok. I also don't run as administrator on my PC.

If it is not safe is there still a way to use it and be (safer)?
It seems to be very usefull.

Depends on how paranoid you are. UPNP allows devices on your network to make temporary changes to your router to forward ports and such. Generally it's ok, but a computer virus could also use upnp but there are other means of NAT traversal. The ISP's response is kind of silly and completely irrelevant, they certainly aren't a good source of information on security.

You should disable WPS (wifi protected setup) on your router. The pin based variants make it possible for some one to crack your wifi in under a minute.

Why do conservative politicians oppose conservation?
Have you ever stopped to think the long-term GOP immigration policy might be to make the United States of America a less desirable place to live than Mexico?

vlan or script to isolate local access. AP isolate if wifi

Generally speaking devices connecting to your home network can only do it with your permission ie: because of an action you took to make it happen.

I disable uPnP on principle. It just makes it too easy for something completely unexpected on the inside of my LAN to use uPnP against me.
