I recently discovered a setting in my router for enabling or disabling UPnP, but there isn't enough information in the router manual to explain which way it should be set for the devices on my network. The router log has multiple entries like the one below, since UPnP is enabled as the default setting:
UPnP renew entry 255.255.255.255 <-> 220.127.116.11:59493 <-> 192.168.0.102:59493 UDP timeout:-1 'Teredo'
I'm connecting two Win 7 Home Premium laptops and a network printer to the router via WiFi. The laptops are connecting at 11n speed while the printer is using 11g. I also have an NAS connected to the router via an Ethernet cable. I occasionally connect my Kindle via WiFi 11g. My Internet modem is a cellular data card.
I've considered disabling the UPnP just to see what would happen, but I though I should first ask if any one on the Forum could explain this feature. Without UPnP will Homegroup stop working? Or will something worse happen?
