UPnP - My router supports this but doesnt work?
im on Vista Ultimate with a NETGEAR DG834G which Im sure supports UPnP , but in past when ive tried to use it its never worked and ive just ran the Microsoft Internet Conectivity Tool which reports all is OK for VISTA but UPnP isnt supported by my router???

can anyone tell me why this is happening?

EDIT: ive checked and its on...
Turn UPnP On ON
Advertisement Period (in minutes) 30
Advertisement Time To Live (in hops) 4


THANKS

TTL of 4 hops seems pretty short, try making that something like 32.

Here's some additional info:
Advertisement Period: The Advertisement Period is how often the router will broadcast its UPnP information. This value can range from 1 to 1440 minutes. The default period is 30 minutes. Shorter durations will ensure that control points have current device status at the expense of additional network traffic. Longer durations may compromise the freshness of the device status but can significantly reduce network traffic.
Advertisement Time To Live: The time to live for the advertisement is measured in hops (steps) for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is allowed to propagate for each UPnP advertisement before it disappears. The number of hops can range from 1 to 255. The default value for the advertisement time to live is 4 hops, which should be fine for most home networks. If you notice that some devices are not being updated or reached correctly, then it may be necessary to increase this value a little.

yeah will do thanks,

but that doesnt explain why UPnP isnt working? the Microsoft Internet Conectivity Tool says its not supported and when I ran a few p2p apps a while ago they too said UPnP wasnt supported and I had to manually open ports (which is bad as they remain open)

I currently use uTorrent and ive opened a port for that and it supports UPnP - iTHINK it may be working with uTorrent as UPnP on the router shows uTorrent as using it BUT its actually the uTorrent firewall rule thats in UPnP - so I wonder if it works by detecting the port being accessed and if the port is in my Firewall Rules then it opens the port for utorrent...??? I dunno I dont THINK so cos UPnP and Manually opening ports are 2 diff things

Well, since we don't support any P2P applications, I'm afraid I can't help you with uTorrent.
