Running Tomato Version 1.04.0944 on Linksys WRT54GS v.4 I went from Thibor to Tomato hoping it would fix this problem. I like Tomato better anyways, but it would be nice if I could fix this. Often UPnP will just stop working - the icon no longer displays in Network Connections. ÂµTorrent is unable to map a port and this UPnP test program fails tests 7 and 8: http://fp.mgillespie.plus.com/upnphelp.htm I am able to get it back up and running if I either clear NVRAM and reconfigure or if I disable UPnP on the router for a bit then re-enable it. I had it working for a while with ÂµTorrent, but then I closed ÂµTorrent and uPnP stopped working. Even when I get it working and don't use any UPnP programs it will still break after time.
