I 've had the router for a few months and have been very happy with the stability.. but I don't think that UPNP on the router works. After having a bunch of apps fail which use UPNP. I then tried some utilities that test UPNP (like upnptest.exe) and I see that they all report a failure of some sort or another. The router also fails to appear in "my network places"
Belkin also has not released any new firmware for the router..
Any insight? Belkin hasn't answered any emails..
